Percy Jackson

''This article is about the character. You may be looking for the the series, the video game, the film, or the film soundtrack.''

"We're staying together. You're not getting away from me. Never again."

- Percy to Annabeth

Perseus "Percy" Jackson is a seventeen-year-old Greek demigod, the son of Poseidon and Sally Jackson. He is the head counselor of Poseidon's Cabin and a former Praetor of the Twelfth Legion at Camp Jupiter. He is currently in a relationship with Annabeth Chase.

Early life
Perseus "Percy" Jackson was born on August 18, 1993. He was raised by his single mother, Sally Jackson. Sally's parents tragically died in an unfortunate plane crash when Sally was five. When Percy was a baby, his father, Poseidon, left to protect him and his mother from evil monsters. However, Poseidon visited him when he was in his cradle, which Percy described as a "golden glow" and his father's warm smile and a hand on his head. When he was a toddler, his mother married Gabe Ugliano, whom Percy despised and called "Smelly Gabe" because of his body odor that smelled like moldy garlic pizza wrapped in gym shorts.

Strange things often happened around Percy, often resulting in him getting into some kind of trouble or getting kicked out of school. When just a baby, Percy was attacked by a snake, but managed to strangle it to death. When he was in third grade, a large man followed Percy around when he was at school, but by threatening to call the police, the teachers eventually got the man to leave. However, nobody believed him when he said that the man had one big eye. When he was in fourth grade, he accidentally hit the wrong lever on the catwalk when his school was visiting the Sea World Shark Pool and made his class take an unplanned swim. Then in fifth grade, he accidentally fired a war cannon which hit the school bus. Percy recounted that he was expelled from six schools over the course of six years.

The Lost Hero
Even though Percy does not appear in this book, it is revealed that he and Annabeth are officially dating. For most of the book, his location was unknown with the only clue being that he disappeared around the same time that Jason Grace, a son of Jupiter, first physically appeared. It is eventually revealed that Jason and Percy were exchanged by Hera/Juno to unite the demigods of Greece and Rome against Gaea and the Gigantes and other creatures.

Percy Jackson's Greek Gods
Shortly after Gaea and the Giants' defeat in The Blood of Olympus, Percy was asked by a publisher in New York to write down what he knows about the Olympian gods, to which the young demigod agreed, reasoning that it would help inexperienced demigods survive any unexpected divine encounters with a major Olympian. Percy proceeds to compile all of the stories that the demigods of Camp Half-Blood and Camp Jupiter told him over the years.

After finishing his narration of the book, Percy mentions being late to a meeting with Annabeth, which worries him.

Percy Jackson's Greek Heroes
A year after finishing writing Percy Jackson's Greek Gods, Percy is approached by the same New York publisher, who, very impressed with the last book, asked him to write one more, this time focusing more on the Ancient Greek heroes. While Percy had originally refused, he was finally persuaded by an offer of a year's supply of free pepperoni pizza, along with numerous blue jelly beans. Percy reasoned that this book would help his fellow demigods, instructing them on how to properly defeat most of the infamous monsters that they might happen to come across.

Right after finishing his narration of this book, Percy reveals that after the events of The Blood of Olympus, he and the rest of the Seven started the tradition of monthly Argo II reunion parties, and he is quite worried about being late to the current one.

The Staff of Serapis
While Percy himself never actually appears in this story, is mentioned multiple times by Annabeth, who was taking the subway to his apartment before encountering Sadie, and is implied to have gone there after the end of her adventure.

The Hidden Oracle
Apollo takes Meg McCaffrey to Percy's apartment because he thinks he can help them. When they arrive he asked Apollo what he was doing here and was shocked to find that he was not a god anymore. He invited the two in when they said they were being followed by malicious spirits.

Percy tells Apollo that he will take him and Meg to Camp Half-Blood, but that needs to focus on his school work as he promised Annabeth that they would attend New Rome University together and that he would also like to meet his younger half-sister. On the way to camp, the three of them are attacked by three Nosoi. One gets to Percy but he summons water from an underground pipe and washes it off of himself and Apollo before the disease becomes deadly, but becomes contested. He gestures for the fallen god to thank him, which he does. Percy tells the two to go to camp, while he talks to a police officer that has just arrived on the scene, and that he will visit the camp on the weekend.

During Nero's attack on the camp, Percy and Mrs. O'Leary arrive via Shadow Travel, and proceed tto attack the huge Colossus, with Percy slicing off spikes from the automation's crown and throwing them to the ground. He and Chiron distract it, while Apollo takes it down with a plague arrow.

After the battle, Percy and Rachel talk with Apollo about what he is going to do next. After he tells then the prophecy he heard in the Grove of Dodona, Percy interprets that his help well be here momentarily, and Leo Valdez arrives shortly afterwards. While the rest of the camp both greets and hits Leo, Percy is so overjoyed, that he only hugs Leo, after which he proceeds to somewhat awkwardly greet Calypso. Percy heads back home soon afterward that, diving underwater with Mrs. O'Leary.

Personality
"He’s actually pretty intelligent, but he acts so dumb sometimes. I wonder if he does it just to annoy me. The guy has a lot going for him. He’s courageous. He’s got a sense of humor."

- Annabeth about Percy

Percy is a brave, spirited natural leader, and is willing to risk his life to save friends, family, strangers, and sometimes even enemies. He has a sarcastic and smart sense of humor, a laid-back demeanor, and has earned the respect of all the Olympians, including Artemis (who strictly dislikes men), Dionysus (who hates most heroes because of what happened with Ariadne), and Hades (who generally hates people). He also earned the trust and respect of the Romans of Camp Jupiter (who usually don't trust Greeks). Percy remains true and never goes back on his word. However, he is definitely not perfect. Percy is somewhat short-tempered, and thus has trouble controlling his anger (such as when he sees bullying) and tends to do or blurt out things before thinking, no matter the consequences, causing him to get into a lot of trouble. He also feels responsible for everyone and anything which goes wrong.

Many people tell him he is brave such as friends, family, strangers, and even gods and goddesses. He also states that he has the same "brooding" look as his father, that always branded him a rebel, and that his mom also has a rebellious streak just like him. Annabeth Chase mentions that he is technically smart but seems to act dumb; and is obtuse, meaning he doesn't always see the obvious even when it is right in front of him, such as people's feelings and what they are trying to see indirectly. Despite this he is perceptive when he wants to (or needs to) be; he could tell that Gaea wanted to keep him alive and gambled his life knowing that he was too valuable to Gaea for him to die at that time. Percy can also be derisively sarcastic and moody, and he dislikes being manipulated or forced to obey. Percy also has small feelings for Annabeth Chase at the beginning of the series and these feelings became romantic over the course of the series, but he finally confirms it in the The Last Olympian. Although Percy is a leader at Camp Half-Blood, he is considered a troublemaker in school, with a track record of expulsions, like most demigods. His dyslexia makes learning and reading difficult, and his ADHD makes it hard for him to be attentive or to sit still in class. He has never been one of the "cool" kids in class because he hangs out with supposedly "un-cool" people, such as Tyson or Grover Underwood. Possibly because of his bad history in school, Percy feels a strong level of affection and attachment to Camp Half-Blood.

After getting his memories taken by Hera, and living on the streets and fighting monsters, Percy has developed a "wolf stare" that says "No matter how bad you think you are, I'm worse," which enables him to scare off people like gangsters. He is not afraid of anything in the mortal world anymore, including gangs. He notes that it is probably Lupa's influence on him, as he stayed with her and her pack for weeks. Despite being very confident in his own abilities, Hazel Levesque can sense there is a quiet sadness in Percy, like he saw his destiny and knew that one day he would face a monster he couldn't beat (similar to how she feels about Jason Grace). In The House of Hades, Hazel states that Percy was a child of Poseidon's better nature: powerful, but gentle and helpful, a person that would guide ships safely to the shore rather than destroy them.

While in Tartarus in The House of Hades, Percy is starting to show a darker and more dangerous side of himself in his personality. He begins to question himself about his morality, and if he's really a good hero or not. He wonders about the people he had previously treated with apathy: Bob, Calypso and Nico di Angelo. After his return, Percy tries to make up for his tattered relationship with Nico by thanking him for visiting Iapetus and leading the Seven to the Necromanteion. While battling Akhlys, Percy taps into his rage and controls poison to overwhelm Akhlys—to the point where even Annabeth is terrified of him. In Tartarus, there are many instances where Percy feels hopelessness and fear, although he ultimately overcomes it. He's shown to be more prone to aggression when he vows to destroy Gaea and avenge Bob and Damasen, something which does not seem to disappear towards the end of the book.

Fatal Flaw
"To save a friend, you would sacrifice the world."

- Athena to Percy about his fatal flaw

Percy's fatal flaw is excessive personal loyalty: he would risk the world and even his own life to save a loved one or even a stranger according to Athena. Athena was obviously displeased that her own daughter is an object of that loyalty. Kronos previously exploited this trait in The Lightning Thief (Sally Jackson), The Sea of Monsters (Grover), and The Titan's Curse (Annabeth Chase). Athena also says "The most dangerous flaws are good in moderation" when Percy protests that personal loyalty isn't all that bad. In The Son of Neptune, Mars states to Frank Zhang that Percy's flaw would hinder the completion of the Prophecy of Seven unless his son manages to intervene, which worries Frank, but Hera, however, states that his fatal flaw will keep the seven together.

Hence, when Gaea finally awakens in The Blood of Olympus and Jason and Piper are determined to help Leo and Festus defeat her, Percy intervenes, intending to fight the Earth Goddess himself. However, before Percy's fatal flaw dooms the war and the world (as Mars had predicted) Frank intervenes, and manages to convince Percy that he must let Jason and Piper do it instead.

Appearance
"He's good-looking, but don't you dare tell him I said that."

- Annabeth Chase about Percy's appearance

Percy is described as a very handsome young man, with jet black hair and bright sea green eyes. Despite most assuming he is tall, this has never been confirmed, with only the fact that he is an inch shorter than Jason and taller than Annabeth being confirmed. He had a gray streak of hair he obtained in The Titan's Curse from holding the sky, but has since lost it, as stated in The Mark of Athena by Annabeth. It is said that Percy gets his handsome looks from his father, Poseidon, a reason why Medusa wanted to preserve a statue of him. At the beginning of the series, Percy was average in athletics but later from his training, becomes very fit, muscular, and lean. He does not seem to know it, or may simply refuse to acknowledge it, but a great number of girls (as well as the homosexual Nico) find him extremely attractive. Even Hazel Levesque stated that "He had the good looks of a Roman god." He is also complimented by Calypso, who when asked whether she was in love with Percy states, "If you could see your face. Of course, you."

After he slew Polybotes in The Son of Neptune, Percy received a tattoo of a trident and SPQR on the underside of his arm to signify that he is a full member of the Roman Twelfth Legion Fulminata. After Annabeth and Percy's reunion in The Mark of Athena, Annabeth says that Percy grew even more handsome, muscular, taller, and that his lips are salty. According to Piper, Percy smells like the sea, looks like a skater and a troublemaker, but she can still see what women would like about him, even if he isn't her type. Piper later states that when Percy pleads, his sea-green eyes seemed to be "like a cute baby seal that needed help," and marvels at how Annabeth had ever won an argument with him.

Abilities
General Abilities= Percy, as a demigod, has these abilities and traits:

ADHD: Percy's supernatural alertness and keen senses that keep him ready for, and alive, in battle. It also lets him analyze his opponents fighting style as well as pick up minor details about an opponent, such as where their muscles tense so he can tell which direction they'll attack from. This is one general trait of demigods.

Dyslexia: Percy's brain is "hard-wired" for reading divine Ancient Greek instead of mortal languages. During his time at Camp Jupiter he learned to understand, and possibly speak, Latin to an unknown degree. This, along with ADHD, is a trait common to most demigods.

Fighting Skills: Percy is a naturally talented and expert swordsman, capable of holding his own against and even defeating larger, more experienced, and more powerful opponents, including gods and Titans as well as monsters. In The Son of Neptune, even after losing the Curse of Achilles, he is still shown to be able to fend off an entire army of continually resurrecting ghosts by himself while still protecting Frank. His Greek training and unpredictable, solo fighting style make him particularly dangerous to the demigods of Camp Jupiter, who are used to fighting as a group, allowing him to easily defeat multiple opponents at once. According to Frank, Percy "fought like a demon." When possessed by eidolons, Percy fought Jason Grace on even footing (Piper couldn't believe the speed of their sword fighting) and injured him to a point that he was knocked unconscious. However, it should be noted that Jason was distracted by Piper's charmspeak at that particular moment, which allowed the possessed Percy to exploit the opening in Jason's defense.

Curse of Achilles (formerly): After bathing in the River Styx, Percy was given supernaturally superior speed and strength as well as invulnerability except for his vital spot opposite of the navel. With the Curse of Achilles, Percy's own combat skills are enhanced to the point where he can single-handedly defeat entire armies as well as gods like Hades and Titans like Hyperion (albeit he had some help in defeating Hyperion). He later loses it by touching the Tiber river as it was a Greek blessing and he could not enter Roman territory with the curse.

Empathy Link: Percy has a psychic connection with Grover called an empathy link. In The Son of Neptune, Don the faun said that Percy had an empathy link with another faun who is Grover.

Eye of Horus Symbol: Percy has an image of the Eye of Horus drawn on his palm, which can allow him to summon Carter Kane wherever he is just by speaking his name, though Percy can use it only once. Percy used this to get Carter and Sadie to Governors Island to help him and Annabeth face off against Setne.

"Not that powerful, eh? Could have fooled me. You're the son of the Earth-shaker, lad. You don't know your own strength."
 * -|Demigod Abilities=

- Hephaestus to Percy Jackson

As a son of Poseidon; one of the Big Three, Percy is an extremely powerful demigod. He has divine authority over his father's domains and subjects. Percy is considered to be the most powerful demigod in Camp Half-Blood. Hazel had considered Nico di Angelo the most powerful demigod she knew, until she met Percy, and believed that Percy's power rivaled Nico's and Jason's abilities. Nico later states that, even compared to the rest of the Seven Heroes of Olympus, Percy is the most powerful demigod he has ever met. Both through his father's authority and his own inherent power, Percy's abilities include:

Water-Induced Abilities: When in contact with or in the presence of water, Percy gains a disproportionate amount of superhuman clarity, strength, speed, agility, and endurance equaling a god and he has shown to be more powerful than Ares while in this state. In The Lightning Thief, Percy was able to defeat Luke in the Camp Half-Blood swordsmanship class after he'd doused himself in water. In addition, after Percy was pushed into the creek during Capture the Flag, he effortlessly defeated four children of Ares in rapid succession, including Clarisse, with ease. However, this only lasts for a limited amount of time unless he is completely submerged in water. He also heals himself from any wound and most poisons when he comes into contact with water, the amount of water and time needed for the healing being proportionate to the severity of the wound.

Hydrokinesis: With the power of the sea within him, Percy can control every form and great volumes of water, being even able to summon and heal his wounds and cure himself of most poisons with it. Percy can control water almost omnipotently. He can control it in order to make it explode, or use it to grab something. His hydrokinesis abilities include:
 * General Hydrokinesis: He can create water from petrified seashells, as well as being able to create water with his own energy and summoning the "force of the ocean" to his will, as long as he concentrates hard enough. He can also harden water into an almost solid shape.
 * Hydrogenesis: Percy can create water from his own power, though it takes much of his energy for him to do so. Percy did this while at Mount Saint Helens, creating water out of nothing to cause a volcanic eruption. He also uses this skill while creating his own personal hurricanes. While traveling on the Argo II during The Mark of Athena, he presumably used this ability while combining his powers with Jason Grace's to create powerful storms.
 * Healing Factor: Since he is the son of Poseidon he can heal most wounds and cure most poisons when in contact with water.
 * Water Propulsion: He can control the water around him to propel himself through water. Percy can shoot water, not only from being in water, but he can blast the own water he creates.
 * Underwater breathing: Percy can breathe underwater and diffuse the oxygen in the water to create oxygen bubbles that allow his non-hydrokinetic friends to breathe underwater. However, in The Last Olympian he was unable to breathe in the River Styx.
 * Water Immunity: Percy can fall from great heights into water, and is unaffected by any amount of water pressure. He does not get wet if submerged in water, unless he wants to. Percy can dry items underwater (as long as he holds onto it), such as a lighter.
 * Water Solidification: Percy can harden water into an almost solid shape. He can use this power to walk on water, by increasing the surface tension of the water to the point where it is solid enough for him to stand on, and water constructs. So far, he has demonstrated creating a strong water shield, and on two instances in The Son of Neptune, he hardened the water into giant hands that followed and imitated the movements of his own hands.
 * Sailing Skills: Percy possesses an intimate awareness of any ship he is on (sailing ships, canoes, motorboats, possibly submarines); being able to telekinetically operate one (as well as anything related to the ocean) because he has perfect bearings on the ocean, he can easily navigate his way at sea.
 * Communication: Percy has divine authority over and can talk (normally and telepathically) to equines and sea creatures who mainly treat him with deference and lordly respect. He can also speak to other children of Poseidon underwater (seen in The Sea of Monsters, in a conversation with Tyson).

Atmokinesis: Percy can summon hurricanes and other types of storms, but the extent to which he can control them is as of yet unknown. Percy's hurricanes have been shown to be powerful enough to douse the fires on Hyperion's body, leaving the powerful Titan vulnerable to attack. By the events of The Son of Neptune he is able to sustain the storm with less effort than his first use of the skill against the Titan Hyperion, although it still drains him over time.


 * Electrokinesis (limited): Percy used this skill unintentionally on one occasion, while creating his own miniature hurricane to fight Hyperion. Sparks of lightning appeared as his hurricane increased in power. His control of this ability, however, is far less than that of a child of Zeus and appears to be a limited side effect of his storms.


 * Aerokinesis (limited): Percy can summon strong winds, which he could use to create storms such as hurricanes and typhoons.

Geokinesis: Percy can generate earthquakes and (consequently) cause volcanic eruptions, but his control of this technique is less than that of a child of Hades.

Cryokinesis: Percy can use cryokinesis to a small degree. He is able to use the ice and snow around him to make an icy hurricane, as he does during the battle in Alaska in The Son of Neptune. He can also manipulate frozen or icy water around him, demonstrated during his interrupted fight with Thalia in The Titan's Curse.

Heat Resistance: Percy has a far higher than normal resistance to heat and burns, similar to that of a Cyclops, due to his father's oceanic nature. He was able to survive being engulfed by lava thrown by the telekhines, though it began to get more painful the longer he was in contact with it, as well not being killed by the super-heated steam from the eruption of Mount Saint Helens.

Toxikinesis (limited): Percy can control and manipulate poisons, as seen when he beats Akhlys in Tartarus in The House of Hades. This is limited, though, as poison is only part water. However, this may only be possible in Tartarus, as the laws of nature act differently there. The full extent of this power is unknown although he is able to control it well enough, when angry, to the point of terrifying Annabeth who even asks him to stop. In The Blood of Olympus Percy tried to divert the poison Polybotes attacked him with, but did not due to his fear of this power.

In The Crown of Ptolemy Percy temporarily hosted the goddess Nekhbet and gained several abilities while doing so. He lost those abilities when Nekhbet left him, but the abilities he displayed while hosting the goddess included:
 * -|Eye of Nekhbet Abilities=

Enhanced Strength: The kopis Percy was wielding felt heavy in his hand except while he was hosting Nekhbet.

Surveillance Magic: Percy was able to see into the Duat with Nekhbet's "super vulture senses". This allowed him to see magical auras and allowed him to see what Setne was doing to the Duat. However while Carter was wearing Annabeth's Yankees Cap Percy couldn't detect him.

Vulture Avatar: Percy could summon a giant glowing purple vulture around himself. He used the avatar to fly and to hold onto Setne while flying. The avatar was also able to protect Percy from Setne's attacks.

Magical Items

 * The Minotaur's Horn, he obtained this when he killed the Minotaur after it supposedly killed his mother, Sally Jackson.


 * Riptide.pngAnaklusmos (Riptide in English), made with celestial bronze, given to him by Chiron to fight monsters. When uncapped, it becomes a 3 foot tall double-edged celestial bronze sword and causes the fear of most monsters around it. Riptide is usually kept as a ballpoint pen when not in use, and will always return to Percy's pocket. It used to be the weapon of Hercules, who got it from Zoë Nightshade. In the movie, Riptide can deflect blasts from Zeus' lightning bolt. When combined with his hydrokinetic powers and Curse of Achilles, Riptide becomes an "arc of pure destruction."


 * The 12th Legion's Eagle, Percy seized the Eagle from the undead army of the frozen Roman Camp on the Hubbard Glacier during The Son of Neptune. He later used it during the battle at Camp Jupiter, where he used its lightning to destroy hundreds of monsters before passing it to Dakota.


 * Medusa's Head, Percy received it at the end of the first book. He cut it off and sent it to Olympus, but Poseidon sent it back. Percy, having no need for it left it with his mom, Sally Jackson. His mom uses the head to petrify her abusive husband Gabe and then sells the resulting "statue" as an art piece named The Poker Player.


 * Stygian Ice Whistle, a special dog whistle made of Stygian ice that was cooled in the River Styx. It was given to him by Quintus (Daedalus) to summon Mrs. O'Leary and shattered after it is blown once. Percy used it when his friends were having trouble fighting an army of monsters in The Battle of the Labyrinth.


 * Wristwatch shield, a wrist watch which turns into a shield, given to him by Tyson. It was badly dented by Dr. Thorn in The Titan's Curse. Tyson came back and fixed it in the beginning of The Battle of the Labyrinth. It was lost later in Battle of the Labyrinth when thrown at Kampê. It was inscribed with the images of the events of The Sea of Monsters, including Percy fighting the bronze bulls, Annabeth killing the Laistrygonian, Tyson riding Rainbow the hippocampus, and Tyson battling the Hydra whilst holding a box of doughnuts.


 * Nemean lion's pelt, obtained in The Nemean Lion Skirmish, when he planned the death of the Nemean Lion. He sacrificed it to Poseidon in The Titan's Curse.


 * Sand dollar, given to him for his 15th birthday by his father. He splits it in half and gave one half to the Hudson River and the other half to the East River gods to stop Kronos' forces on boats in The Last Olympian.


 * Chameleon Armor, he used this in a game of Capture the Flag in the short story of "The Bronze Dragon". It only works from a distance.


 * Hermes' multivitamins, these multivitamins make the person who ate it to be immune to nearly any attack, which was used by Annabeth during the Sea of Monsters to turn Percy back into a human after Circe turned him into a guinea pig and prevent Circe from using magic against her.


 * The Golden Fleece, used after Annabeth was wounded by Polyphemus, he used the Golden Fleece to heal her. Then it was used to save Thalia's tree at Camp Half Blood.


 * Pandora's pithos, this was given to Percy by Prometheus to open it and give up hope. Later he gave it to Hestia to look after it, because "hope survives best at the hearth."


 * Thermos of winds, this was used by Percy and Annabeth in the Sea of monsters to escape the Princess Andromeda and Charybdis. Given to him by Hermes.


 * Magical Pearls, these pearls can transport a person to the sea when smashed. Given to Percy by a Nereid.


 * Moonlace, a flower that grows in moonlight (given to him by Calypso). He planted it at a trough at his apartment, to remember Calypso.


 * Javelins, these aren't normal javelins, because they have a grappling hook, and an explosive setting. Used in chariot races at Camp Half Blood. Used first in The Sea of Monsters.


 * Daedalus' Wings, stolen in a skirmish in the center of the Labyrinth. Now in a trash can after being thrown away, too damaged for further use.


 * Winged shoes, given to Percy by Luke Castellan. In the book the wings spring out when the wearer says "Maia". Percy gave them to Grover. It was supposed to be a trap from Luke, as the shoes almost dragged Grover into the pits of Tartarus, due to Kronos dragging them in. In the film he used these to retrieve a pearl.


 * Travel Rose, which he used in The Sword of Hades to return to the world of the living after having returned Hades’s sword.


 * Kopis, which was created when Percy took Carter Kane's wand and Percy wielded in battle against Setne in The Crown of Ptolemy. Destroyed during the battle.

Love Interests
Annabeth Chase=

"Also, he was reluctant to share his one clear memory: Annabeth’s face, her blond hair and gray eyes, the way she laughed, threw her arms around him, and gave him a kiss whenever he did something stupid."

- Percy about Annabeth



Annabeth Chase is portrayed in the series as Percy's primary love interest and eventually becomes his girlfriend. When Percy first wakes up in The Lightning Thief, he describes her as a "pretty girl with princess curls."

She nursed him back to health after the Minotaur attack. Annabeth disliked Percy when they first met because their parents Athena and Poseidon have a rivalry with each other. Percy eventually developed a crush on her as they both became fonder of each other. Aphrodite told him that they will have a "tragic love life." In The Mark of Athena, Annabeth admitted that she has had a crush on him since they were twelve. Annabeth also stated that she forgave her ridiculous boyfriend (Percy) for everything he's ever done wrong when she realized he rejected Reyna's love for hers.

Annabeth has kissed him (technically) only four times in the original series. Once, after winning the chariot race in The Sea of Monsters, though that was only on the cheek. In The Battle of the Labyrinth, she kissed him again for luck as she leaves him to fight the telekhines at Mount Saint Helens. Then in the dining pavilion of Camp Half-Blood when Percy was trying to show his feelings towards her prior to all the other campers throwing them in the canoe lake in The Last Olympian and again underwater in the canoe lake which Percy described as "pretty much the best underwater kiss of all time."

Annabeth tells Piper McLean that Percy kissed her good night before he disappeared, in The Lost Hero. Percy mentions in The Son of Neptune that whenever he did something stupid Annabeth would kiss him, going on to say that she must have kissed him a lot, which meant he probably did stupid things a lot. In The Mark of Athena, they kiss many times: once when they reunite, once before Percy, Piper, and Jason leave to meet Bacchus, twice in the stables on the Argo II, once before Annabeth leaves with Piper and Hazel to search for a ghost at Charlestown Harbor, once before Annabeth goes to find the map for the Mark of Athena, once after Percy successfully defeats Chrysaor, and once before they depart (when Annabeth goes on a motorcycle with Tiberinus and Rhea Silvia.

Annabeth Chase was jealous for some time, of Rachel Elizabeth Dare, the clear-sighted mortal girl, because Percy spent a lot of time hanging out with her, but Annabeth eventually befriends her after Rachel became the Oracle. Annabeth has also shown jealousy toward Calypso when Percy arrived back at camp after being marooned for two weeks on Calypso's island of Ogygia.

In The Last Olympian, Annabeth states that Percy looks cute when he's worried. It is also well mentioned that she and Percy have officially become a couple and had been dating for four months before he disappeared a short time before The Lost Hero. When Percy went missing, Annabeth was out of sorts trying to find him (even counting how long it's been up to the minute). In the beginning of The Son of Neptune, Percy's only memory of his past life is Annabeth, but it is "frustratingly dim." As the story progressed, she becomes the first person he remembers fully. When the Argo II approaches, with Annabeth on it, Percy states that "If things went right, today would be the best day ever."

Later, Percy gets furious at Hera when she states that Annabeth is a troublemaker and she will cause the most problems during the quest for Greece and Rome, in which Percy states, "She's the person I want most watching my back," and with a fist of water of anger he smashes Hera.

Percy also sees a possibility of a life of college and marriage with Annabeth while at Camp Jupiter when inside the protected city of New Rome. While they were having those two months of dating they had become closer, romantic and more loving toward each other.

When Luke Castellan was still around, Percy would get jealous about how Annabeth would get protective and caring toward him whenever he was accused. It was Luke, though, who made Percy realize his true feelings for Annabeth in The Last Olympian.

In The Mark of Athena, near the end of the book, they fall into Tartarus holding hands when Percy swears that he will never let her go again. In the The House of Hades, Annabeth and Percy's relationship faces its hardest challenges ever while they try to escape Tartarus. However, they make it through by mostly focusing on the life they want to have together in the future. After escaping Tartarus, their relationship has become stronger with Annabeth knowing that she wants nothing more than to have a happy and peaceful life with Percy, who has begun to seriously think about their future together and even the possibility of having a family. Annabeth also states that she doesn't want to break up with Percy and that if that does happen, she cannot look at the sea without getting reminded of her broken heart.

"She would always be my biggest what if."
 * -|Calypso=

- Percy about Calypso

Calypso and Percy first met when Percy was stranded on her phantom island of Ogygia. Calypso had healed Percy after he was severely weakened at Mount Saint Helens. Percy later learns that the immortal Calypso was condemned to live on the island forever after supporting her father, Atlas. She asks him to join her and live with her forever where he would become immortal, but he turns her down, even though it would save him from the prophecy (if he had stayed on the island, he would never turn 16). Calypso was in love with Percy, and he somewhat loved her as well. Percy considered her more beautiful than Aphrodite, "but I wouldn't say that out loud or she'd blast me to ashes,". In The Last Olympian, Percy requested that the Olympians show leniency to the Titans who did not support Kronos, freeing Calypso from her prison. Percy has even stated, that for as long as he lived, she would always be his biggest "what-if". It was revealed that Hera sent Percy to Calypso so she could heal him, while the Fates allowed Percy on the island as he was the kind of person Calypso couldn't help but fall in love with. However, like all other heroes that land on her island, Percy had to leave her, which too was part of her punishment.

In The House of Hades, Calypso reappears. It is known that, when Percy made the gods swear to free her from her prison, she was forgotten, staying trapped on Ogygia. She blamed the gods for this, but also Annabeth, as she thought it was Annabeth's fault she was alone.

"I found myself calling on Rachel a lot, I needed to remember that the mortal world was still out there."
 * -|Rachel Elizabeth Dare=

- Percy about Rachel

Rachel Elizabeth Dare is Percy's only human love interest. Before The Last Olympian, Percy notes that he spent a great deal of time with Rachel. He stated that while he was in the mortal world, he could always call Rachel and she'd be there so they could hang out together. In the beginning of The Last Olympian, the two are seen on the beach in Paul’s Prius driving around. Percy says it was as if his dad were keeping the sea nice, just for them. While they are alone, Rachel admits her feelings in the form of a hypothetical question. However, Beckendorf and Blackjack land on the hood of the car before Percy is able to answer (though he remarks to himself that he felt like one of Apollo's sacred cows—"dumb, slow, and bright red"). After he gets up to leave, Rachel kisses him anyways and tells him to go save the world. It is unsure what Percy's exact feelings for Rachel are, as he never openly states them (though, this may be because of Aphrodite making it hard for him, as she said she would because she likes him). Later on Olympus, Rachel tells Percy that she was drawn to him due to his introducing her to the Olympian world, but that they could never be together as she is meant to become the new Oracle (he thinks she dumped him, "which kinda stunk since we were never dating in the first place"). In the end of The Last Olympian, Rachel and Percy are now simply good friends.

Reyna was bitter towards Percy at the beginning of The Son of Neptune but gradually began to warm up to him as the book went on. She interrogates Percy and throughout the encounter she implies that they've already met. It is later revealed that she once lived on Circe's Island, where Percy and Annabeth unleashed a crowd of pirates, resulting in her and her sister being taken captive. She asks Percy to consider taking Jason's place as Praetor and they could be "friends." Percy seems to feel that Reyna is hinting that it could result in the two of them being romantically involved. He declines Reyna's offer, stating that he already has a girlfriend. Near the end of The Son of Neptune, Reyna smiles when Percy arrives in battle. During the battle, when she sees her sister Hylla, she glances at Percy with a look that says, I could hug you right now.

In The Mark of Athena, Annabeth realizes from Reyna's tone of voice when talking to her that Reyna tried to make a move on Percy, but he rejected this for his love for Annabeth.

Friends
Grover= "Won't change anything, you're still my best friend."

- Percy to Grover



Grover Underwood and Percy have been best friends since they were in middle school in Yancy Academy. At the time, Percy would protect him from bullies and others that would pick on him, but he was not aware of Grover being a satyr. Grover is also the one who helped Percy to get to Camp Half-Blood and helped him on his very first quest in The Lightning Thief. Their friendship is as deep as any of Percy's relationships (excluding Annabeth, his girlfriend) as shown in The Sea of Monsters, when he saved Grover from being killed by the Giant Polyphemus and Grover establishing an Empathy link that connects them emotionally allowing him to know if the other is in danger and what their feelings are (such as when Percy got done talking with Aphrodite and Grover knew that she and him were talking about his love life). Grover had all the satyrs looking for Percy when he vanished in The Lost Hero.

Thalia Grace and Percy first meet at the ending of The Sea of Monsters when she was turned back into mortal form with the Golden Fleece, introducing herself as the daughter of Zeus. As a daughter of Zeus, Thalia was always looked at when in difficult situations, taught to master more complex skills, such as playing with the mist, making Percy feel rather intimidated by her. During The Titan's Curse, their relationship becomes a love-hate relationship that a brother and sister would have, even going as far as fighting with their elemental powers. By the end of the quest however, Thalia considers him a friend, showing him this when she hugged him after she joined the hunt and became a Hunters of Artemis, stating "I am honoring a friend." Annabeth once stated that Percy reminded her of Thalia a great deal, and that they would either have been best friends or strangled each other.
 * -|Thalia=

During the Titan War, she and the other Hunters aided Percy and Camp Half-Blood. She also decided to make lunch plans with him and Annabeth after the war was over, should they all live through it. During The Lost Hero, Thalia is sent by Artemis to search for him and was worried for his well-being showing, that they still have a strong friendship together.

Percy and Leo first meet in The Mark of Athena, but Percy saw images and visions of Leo during The Son of Neptune. They're not particularly close and haven't gotten to know each other well yet, as Percy was initially angry at him for shooting on Camp Jupiter. When Percy was mad at him, Leo was scared, as he recognized the look that reminded him of the times Jason summoned lightning. The two have also shown the same sense of sarcasm and, at times, a degree of ignorance. At the end of The Mark of Athena Leo is filled with guilt because he thinks opening Nemesis's fortune cookie was the reason Percy and Annabeth fell into Tartarus, in spite of Hazel and Nico's objections. Leo then vows to do whatever it takes to rescue Percy and Annabeth from Tartarus, despite thinking someone would have to stay in there to close the Doors of Death from both sides.
 * -|Leo=

In The House of Hades, after meeting Calypso, Leo becomes quite angry and resentful at Percy for seemingly abandoning her, as well as somewhat jealous, since Calypso clearly still had feelings for Percy (which made things "ten times worse" for Leo). Ultimately, however, Leo is the one to save Percy and Annabeth by flinging a screwdriver at the Doors of Death, managing to open them just in time.

By The Blood of Olympus they've finally gotten to know each other somewhat. Leo admits to feeling awkward hanging out with Percy, since he wasn't sure what kind of small talk to make with a recent survivor of Tartarus. He admits that Percy and his impressive powers had been intimidating enough before, with Leo having trouble of even thinking of Percy as part of the same camp as him, since the two of them had never been at Camp Half-Blood at the same time. The only things the two of them had in common are their silly senses of humor and Calypso, and every time Leo thought of the latter, he wanted to punch Percy in the face. He had wanted to discuss the subject with Percy for days, yet the timing had never seemed right, and the subject had gotten harder and harder for Leo to broach as the days went by. They finally manage to talk about it while attempting to fight Nike and her minions. Percy admits to feeling bad about Calypso, feeling that he's failed her, recalling how he'd experienced Calypso's grief after seeing her curse on Annabeth take effect. Percy admits to his mistake without making excuses, admitting that he should have made sure that the Olympians had kept their promise to free her. He is happy about Leo finally finding her, and promises that if he and Leo survive the ordeal at hand, that he'll do anything he can to help Leo find a way back to her, insisting that this is a promise that he will keep. As a result, Leo is finally able to let go of his anger for the son of Poseidon, admitting that he "just couldn't dislike the guy" any longer, due to the latter's sincerity, and is calmed by the confirmation that Percy didn't return Calypso's past feelings.

The two are shown to be very friendly around each other after that, with Leo even nicknaming Percy "Aquaman", much to the latter's chagrin, and also teasing Percy about his Zodiac sign being a Leo. Like the others, Percy is devastated at Leo's death in The Blood of Olympus, and remains hopeful in the possibility of Leo still somehow surviving.

When Leo finally returns in The Hidden Oracle, Percy is so overjoyed to see him, that he, unlike most others, embraces Leo without even punching him.

Some of the things Leo and Percy have in common is a goofy sense of humor, them both having traveled through the Sea of Monsters and encountered Polyphemus, and them both having been marooned on Ogygia, becoming a love interest of Calypso in the process.

"At this point, I was ready to stick the kid in a meat-flavored sack and throw him to the wolves."
 * -|Nico=

- Percy about Nico



Nico di Angelo has the ability to annoy Percy Jackson quite easily when they first met by asking Percy several questions in The Titan's Curse. However, after they go on a quest with his sister, Bianca di Angelo, he understands more about his past. After Bianca dies, it is Percy that decides to break the news to Nico. Nico takes it very hard and begins to hate Percy, blaming him for his sister's death before running away from camp.

During The Battle of the Labyrinth, Percy has dreams about Nico and feels bad for him. While searching for Daedalus in the Labyrinth, Percy runs into Nico at the Triple G Ranch. He completes a job for Geryon to free Nico, even at the risk of Percy having to stay there himself if he fails. Even though Geryon double-crossed Percy, after his defeat, Percy asks Nico to stay on the ranch to keep him safe. Nico begins to open up to Percy more and rushed into the Labyrinth again after King Minos told him Percy was in danger. During the quest, Nico saved Percy many times, especially when Kronos first rose from his sarcophagus in Luke's body; creating a large wall of black rock between them. He even aided Percy when the Titan Army began to attack Camp Half-Blood, but refused to stay. When Nico arrived at Percy's house with a plan to help defeat Kronos, Percy invited him instead and offered him some of his birthday cake.

In The Last Olympian, Percy and Nico have a short falling-out. In order to gain information on his mother, Nico lead Percy to the Underworld to unknowingly speak to his father, Hades. Hades double-crossed Nico and put Percy in his dungeon. Percy becomes angry at Nico for a while, even after Nico saved him and helped him bathe in the River Styx. During the Battle of Manhattan, Percy asks Nico to get his father to help, as Nico is the only one that can; even though Nico wants to stay and help in the battle.

In The Son of Neptune, Nico meets Percy (who has no memory of his past), but says they have never met because Percy needs to find his own way. When Percy does remember Nico later, he becomes angry all over again, stating that he was going to strangle Nico. During The Mark of Athena, Percy never gives up on finding him, and tries hard to free Nico before he runs out of air. When Percy sees Nico's state, he doesn't scold or reprimand him as he had planned. After saving him and almost falling into Tartarus, Percy trusts Nico to lead the other Heroes of Olympus to the Doors of Death on the mortal side so they can meet.

In The House of Hades, Percy realizes that Nico saved his and Annabeth's lives by reminding Iapetus that Percy is a friend. Percy, when on the verge of death from Gorgon blood, admits that Nico is another friend that he had not treated fairly. It is revealed, that Nico is homosexual, and claims he had a crush on Percy, although Nico denies he no longer does. Percy himself knows nothing of these feelings and doesn't return them, though he does care for him like a brother. After returning from Tartarus, Percy comes to thank him for keeping his promise and tries to pick up their tattered friendship, Nico, afraid of his feelings, asks Percy to give him space and leave him alone, much to Percy's confusion and hurt.

At the end of The Blood of Olympus, after Gaea and the Giants' defeat, Nico finally works up the courage to tell Percy and Annabeth about his crush on Percy, and is genuinely happy for them.

"Clarisse: When you, uh, had that vision about your friends… Percy: ''You were one of them. Just don’t tell anybody, okay? Or I'd have to kill you."
 * -|Clarisse=

- Clarisse and Percy

Clarisse La Rue and Percy have a rough relationship. Clarisse dislikes Percy at first for dousing her in toilet water when he first arrives at camp (even though she was trying to dunk his head in the toilet). She later learns that Percy beat her father, causing her and her cabin to dislike Percy. They manage to grow a bit closer in The Sea of Monsters when Percy manages to free her from Polyphemus and sends her ahead with the Golden Fleece, a gesture she greatly appreciates. During The Demigod Files, Percy helps Clarisse get her father's chariot back and has a vision of his friends in danger. When Clarisse asks if she was one of the people he saw, he says yes, but not to tell anyone. While the two can at least stand each other by the end of the original series, they do have great respect for the other.

"Boys, I'm sure you both would've been wonderful at killing each other. But right now, you need some rest."
 * -|Jason=

- Annabeth to Jason and Percy

Jason and Percy have first meet in The Mark of Athena and have been shown to be on good terms. Percy says that Jason "thinks the same way he does" and mentioned a "spark of friendship." They both share many similarities: both are sons of one of the Big Three and extremely powerful demigods; both are excellent swordsmen; both are leaders at their respective camps; both hate Octavian; and both were chosen by Hera to be switched in order to bring the seven Heroes of Olympus together. Annabeth Chase calls their growing relationship a "budding bromance." While fighting Otis and Ephialtes, the two are able to work well together, and they both feel regret about being forced to fight each other by eidolons. It is also shown that when working together their powers get more intense when they created a huge storm at Fort Summer, while fighting the Romans.

The two also have a bit of a rivalry. After the two were possessed and forced to attack each other, Jason apologizes and says that he could have killed him, which Percy quickly turns around and says he could have done the same. Also during a meeting, both Percy and Jason go for the chair at the head of the table and Jason's hand gives off sparks. The two have a silent standoff until Annabeth ultimately takes the seat.

After Percy examines himself and his fatal flaw, he realizes that he feels responsible for everyone on board, including Jason. Because of this, while they are at sea he gets nervous when it is Jason's turn to take watch and feels like he should be the one to protect everyone.

After returning from Tartarus in The House of Hades, Jason is the first one to give Percy a bear hug.

All throughout The Son of Neptune, Percy and Hazel remain very close friends. When Percy first arrives, he saves her and Frank's lives. After, Reyna tells Hazel to show Percy around Camp Jupiter and takes him to Octavian to see whether or not he should join the legion. During evening muster, Hazel says she will stand for Percy, making him a part of the Fifth Cohort. Once, Hazel saved Percy from drowning in quick sand by Gaea. During times of distress or confusion, Percy and Hazel comforted each other and gave advice in a sibling manner. Percy also stated that Hazel was too important to him and wouldn't let anything happen to her. Hazel even kisses Percy on the cheek, even though Percy claims it was a total sisterly kiss. Also, in The House of Hades, Hazel stated that Percy was probably the demigod she admired the most, along with her brother.
 * -|Hazel=

Percy and Piper have first meet in The Mark of Athena, but they are not particularly close and haven't gotten to know each other well yet. Piper seems to think of him as a troublemaker and can see why Annabeth likes him, but feels slightly unimpressed with him after hearing so many stories about him and after comparing him to Jason. Despite this, Piper is shown content having either Jason or Percy being the "leader" of the seven. Piper technically saves his life twice during their quest for the Athena Parthenos and Nico di Angelo. Percy is shown at least twice having faith in Piper's charmspeaking abilities. Percy also shows concern for her by checking up on her after she hurt her shoulder.
 * -|Piper=

Zoë Nightshade is the daughter of Atlas. At first she did not like Percy, but then she came to respect him after it was his plan that helped defeat the Nemean Lion, even giving Percy the pelt after the fight. During the quest, Percy learned more about Zoë's past while having dreams, learning that Hercules had betrayed her after she gave him Riptide. He realized why Zoë seemed to resent all heroes, but in the end, she told Percy that he was nothing like Hercules, and that she was wrong about men. Percy even comes to appreciate a lot of Zoë's good qualities as they spend more time together. Before Zoë's death at the hands of her father, she compliments Percy by saying that he is nothing like Hercules (who betrayed her), and deserved Riptide. After she died at the top of Mount Othrys, Artemis transformed her into a constellation named 'the Huntress' after her death by Artemis, as Zoë is part of the Hunt.
 * -|Zoë Nightshade=

Percy still remembers her from time to time, as he saw her constellation when on Calypso's island, as well as remembering her sacrifice in The Son of Neptune, despite having no memories of his past at the time.

Bob the Titan, originally Iapetus, became Percy's friend after Percy threw him in the Lethe, wiping his memories. He rescued Annabeth and Percy in Tartarus, and stayed behind at the Doors of Death to sacrifice himself. Some of his last words to Percy and Annabeth were, "Say hello to the sun and the stars for me."
 * -|Bob =

"I am your trainer, your teacher. That is not the same as being your leader. I will go gather what allies I can. It may not be too late to convince my brother centaurs to help. Meanwhile, you called the campers here, Percy. You are the leader."
 * -|Chiron=

- Chiron to Percy

Percy has a deep respect and love for his Centaur teacher Chiron, as he helped him as "Mr. Brunner" when he was still attending Yancy Academy and has helped him try to clear his name when he was blamed for being The Lightning Thief. Chiron in return shows a deep love for Percy as that of like a son and became pained when he was missing in The Lost Hero, having almost raised Percy into a young man himself in a way of that a teacher would train and raise their student.

Companions
Blackjack= Blackjack is Percy's pegasus and his loyal friend. While on the Princess Andromeda in The Sea of Monsters, Blackjack was captured and was planned on being recruited into the Titan Army, until Percy set him free. After that, Blackjack became Percy's personal steed and came whenever Percy needed him. Blackjack will also come whenever any sea creature needs Percy's help, normally in the middle of the night (much to Percy's annoyance).

After Percy went missing in The Lost Hero, Blackjack is one of those mentioned to be out looking for him.

Blackjack is also mentioned in The Mark of Athena where he stops the fight between Jason Grace and Percy Jackson, who had both been possessed by eidolons, by knocking Percy on the back of his head with his hoof.

Mrs. O'Leary is Percy's pet hellhound, whom he received from Daedalus before he died in Battle of the Labyrinth. Despite being rather large, even by hellhound standards, Mrs. O'Leary is incredibly friendly toward Percy, licking him anytime they meet. Mrs. O'Leary is very protective of Percy or any of his friends, normally aiding in battles by attacking enemy monsters. In fact, just Mrs. O'Leary's bark and size are enough to frighten other monsters.
 * -|Mrs. O'Leary=

Percy is also very protective of Mrs. O'Leary. When Percy was in the Underworld with Nico and Mrs. O'Leary, he called her off when Nico betrayed him because he didn't want his dog being hurt by the Furies. Despite Mrs. O'Leary being angry with the order, she still obeyed. Mrs. O'Leary and Tyson search for Percy together after he goes missing, eventually finding him at Camp Jupiter and helping fight back the Giant Army.

Family
Sally Jackson= "Mom; Hey, I’m alive. Hera put me to sleep for a while, and then she took my memory, and…Anyway, I’m okay. I’m sorry. I’m on a quest—I’ll make it home. I promise. Love you."

- Percy leaving a message for Sally

Percy loves his mother, Sally Jackson, dearly. He always wishes to make her happy and would do anything to keep her. He is very mindful of her safety, even considering to sacrifice himself for her once. He also left the moonlace from Calypso's Island under her care. In The Son of Neptune, after failing to communicate with Annabeth, he leaves her a phone message letting her know he is safe.

Sally also cares deeply for her son. She worries about him any time he is on a quest and cried with Annabeth Chase when he went missing. Despite Percy always looking for his mom's permission and approval as he gets older, Sally realizes that Percy is getting too old to always listen to her and tells him to do what he thinks is right.

"The way our sons and daughters act in our names… well, it usually says more about them than it does about us. And you, Percy, are my favorite son."
 * -|Poseidon=

- Poseidon to Percy



Poseidon and Percy have a complicated relationship. Percy has a strong admiration and pride for his father, though he initially resented him as he felt he had abandoned him and his mother. Percy let go of this when he learned his father cared for him. Though Percy has met his father only occasionally, he cares very much for his approval and greatly respects him. Poseidon in turn holds a fierce pride for Percy, once calling him a hero greater than Hercules, and claiming him to be his favorite son. An important memory for Percy before he knew he was a demigod was of Poseidon visiting Percy when he was in his cradle in a warm glow and a warm smile. Despite caring for his father, Calypso makes him wonder if he only fights for the Olympians because Poseidon is his father. Percy hasn't been contacted by Poseidon at all after the events of The Last Olympian.

"Sally, I can't claim to know what you and Percy have been going through all these years. But it sounds to me... it sounds like Percy is doing something noble. I wish I had that much courage."
 * -|Paul Blofis=

- Paul to Sally

Percy is at first wary of Sally's new boyfriend, Paul Blofis, but eventually warms to him. Percy is very happy to have Paul as his stepfather when his mother gets married to him. Interestingly, both Percy and Poseidon at first mispronounce Paul's name as "Blowfish."

Percy loves his half-brother Tyson, but couldn't believe they were related when Poseidon first claimed him. He was also kind of ashamed to have a monster for a brother, thinking that his father was trying to make fun of him and that Poseidon gave him no warning about Tyson. This eventually changes after Percy thinks Tyson died when the CSS Birmingham exploded (with Tyson in the engine room). He feels regret for how badly he treated Tyson before and wishes he could take it back. When Tyson turns out to be alive, Percy accepts him as his brother. He and Tyson have gone on many adventures together, and Tyson always looked up to Percy as his older brother. Tyson even used his knowledge of the forge to make a wristwatch that transforms into a shield for Percy. The shield is decorated with images of their adventures engraved upon it, but it was later lost in the Labyrinth. Tyson revealed that he had prayed to Poseidon for a friend, and he had sent him Percy.
 * -|Tyson=

Percy hated his former stepfather. When he was young, he called his stepfather "Smelly Gabe" because he smelled like old pizza wrapped in sweaty gym shorts due to his cigars and non-bathing habits. Sally uses Medusa's head given to her by Percy to turn him into a statue. She sells him and he is currently on display in an unknown museum.
 * -|Gabe Ugliano=


 * -|Frank=

"You singlehandedly took out three basilisks while I was sipping green tea and wheat germ. You held off an army of Laistrygonians so that our plane could take off in Vancouver. You saved my life by shooting down that gryphon. And you gave up the last charge on your magic spear to help some defenseless mortals. You are, hands down, the nicest child of the war god I’ve ever met… maybe the only nice one."

- Percy to Frank

In The Son of Neptune, it is found out that Frank Zhang is related to Percy, although Percy would be his Great, Great (a thousand times)... Uncle. Frank Zhang's ancestor, Periclymenus is the relation linking them. While Percy tries to explain this to Tyson, he caves and says they are all brothers. Frank is first introduced when guarding the entrance to the Roman camp, Camp Jupiter. Percy saves his life when the two gorgons who have been following him, grabs Frank by the arms. Before being claimed by Mars, he hopes that Apollo, God of Archery, will claim him due to his excellent archery skills. Though he doesn't want to be related to Octavian.

Rivals
Luke Castellan= "Percy was almost the same age now as Luke had been then. He could understand how Luke became so spiteful. In the past five years, Percy had been a pawn too many times. The Olympians seemed to take turns using him for their schemes."

- Percy comparing himself to Luke

At the beginning of the series in The Lightning Thief, Percy thought that Luke Castellan was a cool guy and thought that they would become close friends when he came to Camp Half-Blood. Luke helped train Percy in sword fighting and gave him moral support as a new comer, but at the end of the book it is shown to him that Luke was the real Lightning Thief and summons a pit scorpion to kill him and before he leaves, he tells of his bitterness and revenge against the Olympian gods. In The Sea of Monsters, Percy and Luke fight aboard the Princess Andromeda and Percy has him reveal that he was the one who poisoned Thalia's pine tree to the entire Camp Half-Blood. When Luke was supposedly killed in The Titans Curse, Percy is told by his father that Luke was not dead and that he was alive causing him to become angry and filled with more hate. During The Battle of the Labyrinth, Percy witnesses Luke become taken over by Kronos and before that he thrown into a fight against a giant by him. When they go into The Titan War after Kronos has been killed by Luke, he angrily tells Percy with pleading eyes that he didn't want the same thing happen to the other unclaimed demigods wind up like him and Percy honors that promise to him by saying that as his wish that all the children of all the gods will be recognized and cared about. Percy also showed signs of jealousy toward Luke because of Annabeth's affection toward Luke (and Percy's growing feelings for Annabeth at the time). During The Last Olympian, Kronos states that Luke feared Percy.

During The Mark of Athena, Percy starts remembering how angry Luke was with the Olympian gods. Then after seeing Bacchus just watch himself and Jason fighting for their lives against Otis and Ephialtes, he understood why. Because of this, he could understand Luke a little better.

"On the bright side, both Jason and I outrank you, Octavian. So we can both tell you to shut up."
 * -|Octavian=

- Percy to Octavian

When they first met, Octavian was suspicious about Percy, thinking that he's a spy for the Gigantes. At the end of the book, Octavian disliked Percy because he stole his chances of being praetor. He also accused Percy of leading the Greeks to attack Camp Jupiter. Percy has grown a strong dislike toward him as he was black-mailing Hazel about where she really came from, even going as far as saying that he would uncap Riptide from his pocket to protect her from Octavian if she gave him a signal.

Gods
Zeus= "To show you my thanks, I shall spare your life. I do not trust you, Perseus Jackson. I do not like what your arrival means for the future of Olympus. But for the sake of peace in the family, I shall let you live."

- Zeus to Percy

Zeus has mixed feelings for his nephew. He was upset over his birth because it violated the pact that he, Poseidon, and Hades made after World War II to not bear any more children, even as he himself did no better by conceiving Thalia and Jason Grace, and was angered by his nephew personally when he refused his offer of godhood. Zeus is nevertheless thankful for the demigod's past services to both himself and Olympus as a whole. During the winter solstice council meeting in The Titan's Curse, he voted to let him live even when it was no longer tied to the fate of Thalia. However, Zeus once warned Percy that he will strike him down if he ever travels in the sky. Though it is never brought up again by his uncle, Percy is very mindful of traveling by land or sea. However, it seems that in extreme situations, Percy is allowed to travel by plane as evident in ''The Son of Neptune. ''He also allows Percy to fly on Blackjack, and allows him to be carried by the Angel Statues at Hoover Dam.

"That means I can smash him to a pulp as often as I want, and he'll just keep coming back for more. I like this idea."
 * -|Ares=

- Ares when Percy was offered immortality

The god of war despises Percy for wounding him during their duel in The Lightning Thief. It is dangerous that they are on bad terms because Ares thinks highly of revenge and is quite violent. Ares puts a curse on Percy's sword which came into effect during the battle with Atlas. When Percy was later offered godhood, Ares agreed with it because he could fight Percy anytime he wanted and wouldn't have to worry about killing him. As Mars, he seems to treat him with a mixture of amusement and annoyance.

Like Zeus, Hades has a mixed relationship with his nephew due to his natural dislike of heroes. He once believed Percy had stolen his Helm of Darkness until the boy later proved his innocence and returned the helm which the god repaid by returning the boy's mother whom he had kidnapped. In The Last Olympian, Hades briefly imprisoned Percy in his dungeon to ensure Nico became the child of the Great Prophecy. Later, he was convinced by his son to aid Percy and also played an indirect role in his wish for general acceptance and amnesty through past business advice to Nico for getting a "solemn oath." Given that Percy is directly responsible for his position on the council with full privileges and rights, it would be fair to say that Hades has an improved opinion about him.
 * -|Hades=

"Do not judge me too harshly, half-blood. Wise counsel is not always popular, but I spoke the truth. You are dangerous."
 * -|Athena=

- Athena to Percy

Athena is on neutral, if on somewhat unfriendly terms with Percy. She disapproves of his relationship with her daughter, Annabeth both because of his fatal flaw and he is the son of her rival Poseidon. In The Titan's Curse, she guided him at the Hoover Dam in order to save Annabeth though she also suggested it wiser that he be destroyed at the winter solstice meeting. In The Last Olympian, Athena had Hermes send a message to Percy as well as Annabeth, advising how to best prepare for the invasion but also used the opportunity to remind Percy of her displeasure about his relationship with her daughter. Despite her disapproval of him, it was Athena who convinced the other Olympians to honor his request for recognition though she later confronted him about his decision to decline godhood. He admitted Annabeth was the main reason much to her dislike.

During The Mark of Athena, Annabeth pleaded with her mom in the form of Minerva to help her find Percy. Minerva on the other hand hated the Romans, and felt that if Percy had joined them, he should die with them. The fact that Annabeth loved Percy too much to let him go caused a rift between Annabeth and her mother.

Hera neither likes nor dislikes Percy. Both Percy and Annabeth disagree with her views about family, siding with her son Hephaestus even though Hera helped them several times in The Battle of the Labyrinth. Percy is close friends with Thalia, one of Zeus's illegitimate children whom Hera naturally despises. In addition, Percy is the love interest of Annabeth whom Hera cursed for offending her, much like Ares did to Percy for humiliating him. In The Last Olympian, she makes Ares write a thank you letter to Poseidon for saving Olympus, hinting that she may care for him. In The Son of Neptune, Hera sent Percy to Camp Jupiter, have erased most of his memory to her nephew's great annoyance. As Juno she is noticeably more patient with him and answered his questions in his dream without complaint. She commented she considers Percy "a loose cannon" and "impulsive" but also "unswervingly loyal" as well "the glue that will unite the seven". Percy mentions he understands her motives and reasoning for uniting the seven but still is annoyed having lost 8 months of his life as a result.
 * -|Hera=

Both Dionysus and Percy share a mutual dislike of each other. Dionysus detests all heroes in general due to Theseus's treatment of his wife Ariadne while Percy resents his antagonistic attitude towards him and the rest of the campers. On the other hand, Dionysus did once save Percy's life during his quest to save Annabeth and Artemis. He also correctly remembered Percy's name in a conversation they had after he saved Percy on said quest (Dionysus is notorious for mixing up and forgetting the names of campers, though they know that he does this on purpose). Then at the end of The Battle of the Labyrinth, Dionysus gives Grover his support after learning of Pan's death and cures Chris Rodriguez of his madness. Despite their mainly tense relationship, Dionysus favors Percy with his advice, aid, and judgement more than any other god in the series. This indicates that Dionysus likely acknowledges Percy, especially after the end of the second Titan War though he did tell Percy he would still try to make his life miserable at camp. As Bacchus, they treat each other the same as normally despite Mr. D being Roman aspect of himself as he helped Percy fight the Twins Giants inside the Colosseum, Rome. He also warns Percy that his future is in extreme danger.
 * -|Dionysus=

"Good-bye, lad. You did well, destroying the telekhines. I’ll always remember you for that."
 * -|Hephaestus =

- Hephaestus to Percy

Traditionally, Hephaestus has close ties with Percy's father Poseidon in the form of the Cyclopes who work for both of them. Hephaestus is personally grateful to Percy for having discovered and eliminated those who invaded his forge under Mount Saint Helens even though he not only destroyed the forge but ultimately freed Typhon. Though he was impressed with the boy's performance in the battle for Olympus, he mentions to Leo in The Lost Hero that he sees Percy as an ingrate and upstart for refusing immortality and demanding that the gods pay closer attention to their children.

"You did well, for a man."

Percy is on Artemis' good side since he helped find and save her in The Titan's Curse. She even declares him a hero before Olympian Council and calls him a man rather than a boy after he helped her defeat Atlas. Percy's friendships with Thalia and Zoe as well as his loyalty to others regardless of gender places him in the highest regard in her eyes. In The Lost Hero, she sent her Hunters in search of him, deliberately defying her father's orders in order to do so. It is unknown but likely that she knows what happened to him.

Percy is on good terms with Hermes who convinced him to go on a quest in The Sea of Monsters and gave him magic items to assist him in his journey. He also explained the relationship between gods and heroes to him. Later, their relationship soured after realizing that Percy could not save Luke Castellan. After the war, their relationship was mended upon Percy's counseling and sympathy for Hermes' feelings of powerlessness for Luke's fate. Hermes trusted Percy enough to seek him out for help in retrieving his stolen Caduceus, and repaid Percy's favor by treating him and Annabeth to a magically arranged dinner in Paris for their one-month anniversary.

"Always some monster. But my dear Percy, that is why the others are on this quest. I'm more interested in you."
 * -|Aphrodite=

- Aphrodite to Percy

The goddess of love and beauty favors Percy, having expressed an interest in his relationship with Annabeth Chase. She told that Percy that she planned to meddle with his love life, intending to make it a "nice tragic love story". It was Aphrodite who arranged for Percy to meet Rachel and later Calypso, causing him to be confused about his feelings for Annabeth.

At the end of The Last Olympian, Aphrodite was one of the gods who voted in favor of Percy being granted godhood. She was also one of the gods who voted not to kill Percy at the winter solstice.

Apollo tends to side with Percy and can see the good he does. While Percy goes on a quest to try and save Apollo's sister Artemis in The Titan's Curse, he helped Percy directly which goes against the ancient laws of gods, but put his faith in Percy that he would be able to save her.

"My lord Hades, are you sure we can’t let this little hero go? He’s awfully brave."
 * -|Persephone=

- Persephone to Hades about Percy

Percy only met Persephone twice, but he came off worse both times. In The Demigod Files, Persephone tricked Nico, Percy, and Thalia into recovering Hades' new sword. In The Last Olympian, Percy is considered by Persephone to be brave, but she does not vouch for him against Hades and shrugs indifferently when Hades states that he will imprison Percy and make himself king of the gods when Nico turns sixteen.

Aside from his father, Hestia is possibly Percy's best relationship with a god. Percy actually first saw Hestia his first day at camp but thought she was an eight-year-old girl. Hestia helps Percy several times in The Last Olympian which he repays by entrusting her with Pandora's pithos as "hope survives best by the hearth." Percy's respect for her goes as far for him to tell her she is "the last Olympian and the most important".
 * -|Hestia=

Enemies
Kronos= He is the main antagonist of the whole story, but being the father of the Big Three gods, he is Percy's grandfather. Like Percy said, "Being the son of Poseidon and all, I guess that makes him my grandfather." Percy thought it so strange he dismissed it completely. Nevertheless, Percy is Kronos' grandson. Kronos has tried to recruit Percy several times, but to no avail. Through the Great Prophecy, Percy was the demigod who chose to save Olympus and ultimately defeat Kronos by giving Luke the "cursed blade."

He is the only Titan that is on the good side with Percy. In The Demigod Files, while he is fighting Percy, Percy tricks him into splashing into the River Lethe, wiping his memory clean. He emerges believing he is a man named Bob and his friend is Percy. However, he is presumed dead after fighting the embodiment of Tartarus and ensuring Percy and Annabeth reach the mortal world safely in The House of Hades.
 * -|Iapetus=

He and Percy have a similar hateful relationship. He and Percy fight and he easily got furious; Percy had a mini-hurricane around him, extinguishing Hyperion's light. Soon, the satyrs' magic transformed him into a tree in The Last Olympian. In The House of Hades, Percy convinces Iapetus to pierce Hyperion's reforming "bubble", and is later annoyed that Hyperion "doesn't stay dead." When preparing to get to the Doors of Death, Percy is afraid that Hyperion might sense his presence, and moves further away from him.
 * -|Hyperion=

As a Titan, his curse was to carry the weight of the sky on his shoulders. Close to the events of the Titans Curse he succeeded in getting Luke to carry the sky so that he could fight. Then he tricked Annabeth into carrying it, who then got Artemis to take the burden. Percy then relieved Artemis of the sky so she could fight. Finally Atlas ends up with the sky again because of Percy, so it is heavily implied that Atlas hates Percy.
 * -|Atlas=

Prometheus and Percy have mixed feelings for each other. Prometheus says he likes heroes because Hercules freed him from being chained to a rock with vultures. Although Percy regards him as "a slimy worm," he becomes more respectable of him after he shows Percy a vision of Hermes lecturing Luke. It is unknown if they meet again, and if they do meet again, it will probably be under better terms as they are now no longer enemies, but it will still be unknown if Prometheus will be assisting the Titans or the gods now.
 * -|Prometheus=

Percy and the giant Polybotes have a large amounts of dislike for each other, as Polybotes is the Bane of Neptune and has attempted to capture, torture, and eventually kill Percy. According to Polybotes, Percy's blood will bring back the Earth Mother, but before that he wants to torture Percy and keep him as a pet until the time is right. In The House of Hades, Polybotes hates Percy more than ever, and is determined to avenge his death by chasing him all over Tartarus. However, after Percy and Annabeth tumble into the domain of Night, Polybotes refuses to follow them there, and leaves them for dead.
 * -|Polybotes=

Alcyoneus has respect for Percy, as he has been watching him all his life and knew he was the one to defeat Kronos. However, because of his orders from Polybotes, he apologizes that he will not be able to kill him. Beyond this conversation, the two share no more interaction.
 * -|Alcyoneus=

Throughout The Son of Neptune, Gaea, the goddess of the Earth has been sending Percy dreams and speaking to him. While she is speaking to him, she told him affectionately that he was her "important little pawn" and that he would be the ultimate key to the Olympians' defeat. In turn, Percy hates the goddess for her trying to destroy his friends at both Camp Jupiter and Camp Half-Blood, as well as the Olympians, especially as this includes his father. In The Mark of Athena, Gaea personally chose Percy to be her sacrifice for blood to make her raise, she also appears to him in a near like human form calling him her "dear friend" along with her "little darling pawn". She is also very active towards Percy, as she appears to him more than the other Seven, appearing in a human-like form during The Mark of Athena, telling him to enjoy Tartarus and that he will fall to her. In The House of Hades, after Iapetus and Damasen are forced to sacrifice themselves, Percy vows to defeat Gaea and avenge them.
 * -|Gaea=

According to Alcyoneus, Gaea hates Percy more than anyone else, with the possible exception being Jason Grace.

The Lightning Thief
Percy is portrayed by Logan Lerman. His character's age has been increased from 12 to 16 to appeal to older viewers. Throughout the film, Percy has not been shown to be able to remain dry underwater, or anywhere else either.

The Sea of Monsters
Percy is again played by Logan Lerman.

Video Game
In the video game, Percy appears as the main protagonist. After getting more than three characters, besides Percy, the player may decide upon switching, however, Percy cannot be replaced. His attacks are mostly Water based. He also has a few Physical attacks and one Poison attack. He is resistant to Water but is vulnerable to Poison. The table below contains all the moves he can learn throughout the game.

Etymology
Perseus is a Greek name coming from the original hero, Perseus, meaning "Destroyer" or "To destroy" , alluding to his role in the Great Prophecy (i.e, Olympus to preserve or raze). It could also ompare to his father, Poseidon, as he is known as the Earth-Shaker, often destroying places due to earthquakes. His mother, Sally Jackson, named Percy after the hero Perseus, as he was the only hero who had a happy ending in the Greek myths.

Jackson is a very common name of English and Scottish origin, coming from "Son of Jack" as many U.S political parties.

Trivia

 * Percy's birth date, August 18, wasn't revealed until The Last Olympian.
 * Percy's real name, Perseus, is used by many of his enemies and many gods in the Percy Jackson and the Olympians series. In The Heroes of Olympus, he is mostly addressed as Percy, with the exception of The Blood of Olympus, in which he is referred to as Perseus by Polybotes and Kymopoleia.
 * Percy never revealed his real name to anyone prior to the events of The Lightning Thief, when he first arrived at Camp Half-Blood.
 * His real name comes from the fact that Perseus, a son of Zeus, was one of the only heroes in Greek mythology to have a happy ending (although Percy originally favored Hercules).
 * Percy claims to have never gotten a grade higher than a C- in The Lightning Thief. However, in The Ultimate Guide, his report card gives him a B- in science. This may be from after the events of The Lightning Thief, possibly from his time in seventh grade (since he and Tyson successfully completed a science exam the fastest thanks to the latter's clumsiness).
 * Percy is horrible at archery, as shown in The Lightning Thief, The Battle of the Labyrinth, and The Demigod Files. However, he has improved, as it is shown in his report card that "he has stopped shooting his own teammates."
 * Percy has done many things that previous demigod heroes and mortals have such as:
 * Slayed the Minotaur twice (once in The Lightning Thief, and later in The Last Olympian), defeated Procrustes, and entered the Labyrinth as Theseus did.
 * Killed Medusa as Perseus did (The Lightning Thief).
 * Got the Golden Fleece as the first Jason did (The Sea of Monsters).
 * Battled and defeated the Nemean Lion, fought the Erymanthian boar and the Hydra and entered the Garden of the Hesperides as Hercules did (The Titan's Curse).
 * Entered the Underworld alive (multiple times) and returned alive as Hercules, Orpheus, Odysseus, and Houdini did.
 * Bore the Curse of Achilles as Achilles did (The Last Olympian).
 * Killed a snake as a young child as Hercules did (The Lightning Thief).
 * Faced the Sirens, Scylla and Charybdis, Circe, and Laistrygonians as Odysseus did (The Sea of Monsters).
 * Taunted Polyphemus and escaped his cave as Odysseus did (The Sea of Monsters).
 * Took the Gray Sisters' eye and threatened them for directions to a location as Jason and Perseus did (The Sea of Monsters).
 * Carried Hera/Juno in another form across a river like Jason did (The Son of Neptune).
 * Held the weight of the sky like Hercules did. (The Titan's Curse)
 * Fought Ephialtes and Otis, like Hercules and Dionysus did (The Mark of Athena).
 * Faced Alcyoneus, like Hercules did (The Son of Neptune).
 * Confronted Phineas, like Jason and the Argonauts did (The Son of Neptune).
 * Spent time with Calypso, like Odysseus did (The Battle of the Labyrinth).
 * Fought in the Giant War like Hercules and Dionysus did (The Blood of Olympus).
 * He has fought a total of five Titans, two of which he defeated (Artemis ultimately defeated Atlas). He also defeated a Giant, a feat which no other hero had accomplished other than Jason Grace who dueled Porphyrion, Hazel Levesque and Frank Zhang who killed Alcyoneus, and Dionysus and Hercules who fought alongside the gods against Typhon and the Giants and won both battles before they were granted immortality.
 * On the cover of The Battle of the Labyrinth he is seen opening Kronos's sarcophagus, while in the book he was wearing Annabeth's invisible Yankees cap.
 * He is claustrophobic, as shown when he went up the arch. However, this doesn't seem to affect him in the Labyrinth.
 * Some of the reasons that Percy Jackson got expelled were "accidentally" aiming a Saratoga battle cannon at his school bus, and hitting the wrong lever on a catwalk that made his class take an "unplanned swim" into the shark pool. Both are mentioned in The Lightning Thief.
 * During The Son of Neptune, the only things Percy remembers are Annabeth, the fact that he is a demigod, and that Annabeth had some vague connection with San Francisco as well as her being his girlfriend, her looks, and the way she laughed and kissed him every time he did something stupid.
 * Poseidon mentioned that Percy has risen above every hero, even Hercules.
 * Percy is the only child of the Big Three without any known living demigod siblings so far.
 * Percy, like Annabeth, at one point dreamed of getting his parents back together.
 * Percy is the only one that has been able to keep the River Lethe from erasing his memories, as Percy won't get wet in water because he is a son of Poseidon.
 * Percy Jackson is based on Rick Riordan's son, Haley, who has ADHD and Dyslexia.
 * Percy appears on the cover and in the story line of almost every novel in both the Percy Jackson and the Olympians series and The Heroes of Olympus series. The only novel on which he does not appear on the cover or story is The Lost Hero and The Blood of Olympus.
 * Oddly, Percy seems to understand Latin in The Son of Neptune after being at Camp Jupiter for a short time, while Jason cannot seem to understand Ancient Greek during The Lost Hero even though he has been at Camp Half-Blood for longer. The reason for this is probably because Chiron taught Percy Latin back at the beginning of The Lightning Thief.
 * Hazel thinks that Percy and Jason Grace are similar in personality, as they both give off the aura of power and authority, but also a sadness that they have seen their destinies and are waiting for the day when they will face a monster that they cannot beat. Other ways that they have in common (besides being best friends) are:
 * They have both been praetor at some point by being raised on a shield.
 * They have a girlfriend (Annabeth Chase, Piper McLean).
 * Aside from each other, they had a best friend (Grover Underwood, Leo Valdez)
 * At some point in the quest, each had girls that did not trust them (Piper McLean wasn't sure of Percy at first and didn't catch her eye as a hero, and Hazel Levesque and Annabeth Chase disliked Jason as he seemed too perfect).
 * They were kidnapped and switched by Hera.
 * Both of their godly parents (Jupiter and Poseidon) didn't appear at all in the Heroes of Olympus series until The Blood of Olympus.
 * Both were under charmspeak by a sorceress (Circe, Medea) which backfired.
 * They were both compared to a superhero (Aquaman and Superman respectively).
 * He's distantly related to his friend Frank Zhang due to his ancestor Periclymenus, something Percy tells him he is proud of.
 * Hera told Percy that the Heroes of Olympus must come together; but Percy was the only demigod to be said to be a Hero of Olympus by the Olympians themselves in The Heroes of Olympus.
 * In The Demigod Files, we see that Percy's worst fear is the camp in flames with his friends dead, or it could be interpreted as losing those close to him.
 * Percy is Poseidon's favorite son.
 * Polybotes thinks if he harms Percy, Poseidon will become weakened due to his love of his son.
 * Percy is the only known bearer of the Curse of Achilles not to be killed by their weak spot and the only one known to lose it.
 * The River Styx is the only river Percy cannot control or breathe in.
 * Percy has two pets, Mrs. O'Leary and Blackjack. As a result, he held the record of having the most pets out of every single demigod except for (as revealed in The Son of Neptune) and later tied with (as of The House of Hades) Reyna.
 * Percy Jackson is one of only five characters whose birthday was revealed in the books. The other four are Thalia Grace, Hazel Levesque, Jason Grace and Annabeth Chase.
 * Percy has only led one quest but has been on multiple others.
 * In the film adaptions Percy's age within the first Great Prophecy changed from being sixteen to being twenty, meaning that Percy was sixteen in the first film and seventeen in The Sea of Monsters.

 * Percy told Thalia Grace in The Titan's Curse that he likes listening to alternative rock and bands such as The White Stripes. He says that it's one of the "only CDs he owned that his mom liked."
 * As of The House of Hades, Percy, Annabeth, and Nico are the only demigods known to have gone to Tartarus and survive the experience.
 * In The Battle of the Labyrinth, when Percy first arrived on Ogygia, he said, "Holy Poseidon." In The House of Hades, when Leo Valdez first arrived on Ogygia, he said, "Holy Hephaestus." Poseidon and Hephaestus are their respective godly parents.
 * It was mentioned in The Son of Neptune that it was unheard of for a probatio like Frank Zhang to be promoted directly to centurion rank. Percy was still probatio when he was made praetor, the highest rank at Camp Jupiter.
 * He is also the first and only known Greek to hold a position of leadership within Roman ranks.
 * Percy is thus far the only known demigod to be involved with two major prophecies in both series: he is the "half-blood of the eldest gods" mentioned in the Great Prophecy and one of the seven half-bloods in the Prophecy of Seven.
 * Percy is the only one out of the seven who can't speak a second language (excluding Ancient Greek and Latin).
 * Percy is called "Peter Johnson" several times by Dionysus throughout the Percy Jackson and the Olympians series. He has also been called are Perry Johansson, Pierre, Pedro, and Jorgenson by Dionysus in The Battle of the Labyrinth and The Last Olympian.
