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.

"But actually I'm the son of Poseidon. I'm from Camp Half-Blood."

- Percy talking to the giant

Perseus "Percy" Jackson, (Περσεύς or Περσέας in Ancient Greek) is the main character and the narrator of the Percy Jackson and the Olympians series as well as one of the main characters in the Heroes of Olympus series. He is the son of Poseidon and Sally Jackson. Percy is one of the heroes mentioned in the first and second Great Prophecies. He is currently Annabeth's boyfriend and is currently a Praetor of the Twelfth Legion at Camp Jupiter after he was sent there by Hera (Juno). He is portrayed by Logan Lerman in the film.

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 Chase Percy is brave, a natural leader, and is willing to risk his life to save friends, strangers, and sometimes enemies. He has a sarcastic and smart sense of humor, a laid back demeanor, and has earned the respect of all the Olympians, even Artemis (who strictly dislikes boys), Dionysus (who hates most heroes), and Hades (who generally hates people). Despite this, 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 (when he sees bullying) and tends to do or blurt out things before thinking, no matter the consequences, causing him to get in a lot of trouble. 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. Despite this he is perceptive when he wants 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 sarcastic and moody, and he dislikes being restrained or forced to obey. Percy also has small feelings for Annabeth Chase at the beginning of the series, but finally confirms it in 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 ADHD and dyslexia make learning difficult, and 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.

After getting his memories wiped by Hera, and living on the streets, fighting monsters, Percy has developed a "wolf stare" that says No matter how bad you think you are, I'm worse. 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.

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

- Athena Percy's fatal flaw is excessive personal loyalty: He would risk the world and his own life to save a loved one. Athena was obviously displeased that her own daughter was an object of that loyalty. Kronos previously exploited this trait in The Lightning Thief, The Sea of Monsters, The Titan's Curse. 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 that this flaw would hinder the completion of the Second Great Prophecy, which worries Frank. Hera also states that his fatal flaw will keep The Seven together.

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

- Annabeth Chase Percy is described as a fairly tall very good-looking young man, with jet black hair and bright sea green eyes.He gets his looks from his father at the beginning of the series percy is averge in athlectics but later from his training, becaomes ver fit and muscular. He does not seem to know it but many girls find him very attractive, as stated by Hazel " He had the good looks of a roman god" He also has a gray streak in his hair from holding uo the sky in "The Titans Curse" he is stated to be around 6'ft

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

- Hephaestus Percy, as a demigod, has these 'disabilities' 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.
 * Dyslexia: Percy's brain is "hard-wired" for 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.
 * Limited Clairvoyance: Percy is able to watch events in distant locations and times, particularly hidden things because of his father's unpredictable nature. He occasionally takes the place of a different person in his visions (such as Hercules).
 * Fighting Skills: Percy is a natural and expert swordsman, capable of holding his own against larger, more experienced, and more powerful opponents, including gods and Titans. 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 a time.
 * Curse of Achilles: 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. He later loses it by touching the Tiber river as it was a Greek curse.
 * Empathy Link: Percy has a psychic connection with Grover called an empathy link.

Demigod Abilities
As a son of Poseidon; one of the Big Three, Percy is more powerful than the children of lesser gods. He has a degree of divine authority over his father's domains and subjects. Hazel had considered Nico di Angelo the most powerful demigod she knew, until she met Percy, and believed that Percy's power might even rival Nico's (and even Jason Grace's). Both through his father's authority or his inherent power, Percy's powers include:
 * Water-Induced Abilities: When in contact with or in the presence of water, Percy gains a disproportionate amount of clarity, strength, speed, healing, dexterity, reflexes, agility, and endurance equalling a god and he has shown to be more powerful than Ares while in this state. However, this only lasts for a limited amount of time unless he is completely submerged in water.
 * 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 with it. Percy can control water almost omnipotently. He can control it in order to make it explode, or use it to grab something. Some of his hydrokinetic powers are listed below:
 * He can heal most wounds and cure most poisons when in contact with water.
 * 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.
 * 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 harden water into an almost solid shape. He can do this to walk on water or make water shields.
 * Percy can diffuse the oxygen in the water to create oxygen bubbles that allow his non-hydrokinetic friends to breathe underwater.
 * Percy can breathe underwater, 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 temporarily dry items underwater, such as a lighter.


 * 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 Posideon/Neptune underwater (seen in The Sea of Monsters, in a conversation with Tyson ).
 * Aerokinesis: Percy can summon hurricanes and other types of storms, but the extent to which he can control them is as of yet unknown. 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.
 * Geokinesis: Percy can generate earthquakes and (consequently) cause 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. 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 as 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 telekines, though it began to get more painful the longer he was in contact with it, as well not being killed by the superheated steam from the eruption of Mount St Helens.
 * Misc: While fighting the Furies on his first quest, Percy, uses a random bout of Latin, telling his former pre-algebra teacher to "Eat my pants." This not being normal since Percy is supposed to know ancient Greek, not Latin like the Roman demigods.

Magical Items

 * The Minotaur's horn, he obtained this when he killed the Minotaur after it supposedly killed his mother, Sally Jackson.
 * Anaklusmos (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 Zoe 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 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.
 * Stygian Ice Whistle, a special dog whistle made of un-meltable 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 Kampe. 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 split it in half and gave it to the Hudson River and 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"
 * Hermes' multivitamins, these multivitamins make the person who ate it to be immune to nearly any attack, which was used by Annabeth Chase during the Sea of Monsters to turn Percy back into a human after Circe turned him into a guinea pig.
 * 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. He then 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.
 * 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.
 * Daedalus' wings, stolen in a skirmish in the center of the Labyrinth. Now in a trashcan 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 Castellan, 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 magical pearl.
 * A magic Travel Rose, which he used in The Sword of Hades.

Annabeth Chase
""Also he was reluctant to share his one clear memory: Annabeth's face, her blond hair and gray eyes, and gave him a kiss every time he did something stupid""

- Percy thinking about Annabeth in "The Son of Neptune" Annabeth is portrayed in the series as Percy's primary love interest and eventually became his girlfriend. When Percy first wakes up in The Lightning Thief, he describes her as a "pretty girl with princess curls". She is nursing him back to health after the Minotaur attack. Annabeth disliked Percy when they first met (because their parents Athena and Poseidon have a rivalry), while Percy was developing a crush on her, but soon they grow fond of each other. Aphrodite told him that they will have a 'tragic love life'. Annabeth has kissed him (technically) five times, once, after winning the chariot race in The Sea of Monsters, though that was only on the cheek, in The Battle of the Labyrinth again for luck as she leaves him to fight the telekhines at Mt. St. Helen's, next in the dining area of Camp Half-Blood, prior to all the other campers throwing them in the canoe lake in The Last Olympian, and underwater as he described as "just-about-the-best-under-water-kiss-ever.". It is just mentioned, but Annabeth tells Piper that Percy kissed her good night before he disappeared. Annabeth was jealous for sometime of Rachel, 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 also showed jealousy toward Calypso after Percy arrived back at camp from coming from Calypso's Island. Percy describes her as being "always cute" but soon described her as being seriously beautiful ("I mean, she'd always been cute, but now she was becoming seriously beautiful"-Percy, The Last Olympian). Annabeth also states that Percy looks cute when he's worried (again, The Last Olympian) It is also well mentioned that she and Percy have officially become a couple (in The Lost Hero). When Percy went missing, Annabeth was out of sorts trying to find him (even counting how long it's been). In the beginning of The Son of Neptune , Percy's only memory is of his past life is Annabeth, but it is "frustratingly dim" ("A vague sadness weighed on his chest. Something told him he'd been to San Francisco before. The city had some connection to Annabeth- the only person he could remember from his past"). As the story progresses, 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." Percy gets furious at Hera when she states that Annabeth is a troublemaker and she will cause the most problems durring 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. Also it is stated by Percy that he and Annabeth had 2 great months of dating before he was taken away by Hera. When they were having those two months of dating they had grown more close together and more romantic and loving toward each other. When Luke was still around Percy would get jealous about how Annabeth would get so protective and caring toward him and it was Luke though that made Percy realize his true feelings for her when Luke was dying after the Titan War (The Last Olympian).

Calypso
""She would always be my biggest what if""

- Percy about Calypso in The Battle of the Labyrinth

After Percy was stranded on the island of Ogygia, he was healed by an immortal named Calypso who 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 the Fates sent Percy to Ogygia, as they were cruel and sent Calypso companions who would have to leave.



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

- Percy about Rachel in the Last Olympian

Percy and Rachel were known to have spent a lot of time together in his normal everyday living, and she was known to have filled the void in his mortal life. 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 Last Olympian, they were out on a beach together after Percy had driven his stepdad's car out to that spot. Percy says it was as if his dad were keeping the sea nice, just for them. While they were alone, Rachel admits her feelings in the form of a hypothetically question (seen above), but Beckendorf and Blackjack landed on the hood of Paul Blofis' Prius before he could answer (though he remarked to himself that he felt like one of Apollo's sacred cows- "dumb, slow, and bright red"). After he got up, Rachel kissed him anyways. 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). However, Percy's growing love for Annabeth never stopped so Percy and Rachel's love life didn't progress as much as his with Annabeth's had. 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 went on to become the new Oracle. (he thinks she dumped him, "which kinda stunk since we were never dating in the first place")

Reyna
Percy Jackson met Reyna in The Son of Neptune. At first Percy was thinking that Reyna was not human.Then they had this talk, and Percy discovers the true feelings beneath her. It was said that the two Praetors could have a very deep relationship with each other aside from being very close friends, they could get romantic relationship. Near the end of the son of neptune, Reyna told Percy, I could hug you now (during the war). Although Reyna gets emotional thinking about Jason Grace, but she is starting to really like Percy, not because of his strength, speed, and brains, but she likes him for his extremely high level of wisdom, courage, love, friendship, and loyalty.

Sally Jackson
Percy loves his mother, Sally 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 in 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.

Poseidon
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, calling him a hero greater than Hercules. He even once called him his favorite son.

Paul Blofis
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."

Tyson
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. He and Tyson have gone on many adventures together, and they love each other a lot. Tyson always looked up to Percy and even used his knowledge of the forge by making a wrist watch that transforms into a shield for him with their adventures from the sea of monsters on it, but it was later lost in the Labyrinth. Tyson later revealed that he had prayed to Poseidon for a friend, and he had sent him Percy.

Gabe Ugliano
Percy hates 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 not taking many showers. He is turned to stone when Sally uses Medusa's head. She sells him as a statue and he is on display in an unknown museum.

Frank Zhang
In "The Son of Neptune " it is found that Frank Zhang is related to Percy, although Percy would be his Great, Great ... 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.

Zeus
Zeus has mixed feelings for Percy. 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 possibly Jason, 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 unless impossible.

Hades
Like Zeus, Hades has a mixed relationship with his nephew, given 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 both 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 "permanent" seat on the council with full privileges and rights, it is fair to say that Hades has an improved opinion about him.

Ares
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 when Percy was fighting Atlas. Later, when Percy was offered godhood, Ares agreed with it because he could fight Percy anytime he wanted (which he thought would be fun) and wouldn't have to worry about killing him. As Mars, he seems to treat him with a mixture of amusement and annoyance.

Athena
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 because he's 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 voted 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 and counter 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 though he added his friends as others (to which Athena replied "spare me").

Hera
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 numerous times in The Battle of the Labyrinth. Percy is close friends with Thalia, one of Zeus' illegitimate children who 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. However, it is not known if Hera included Percy in this statement. 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 Lost Hero Hera sent Percy to Camp Jupiter, erasing most of his memory.

Dionysus (aka "Mr.D")
Both Dionysus and Percy share a mutual dislike of each other. Dionysus detests all heroes in general which he reveals in the The Titan's Curse to be due to to Theseus' treatment of his wife, Ariadne while Percy resents his antagonistic and sometimes callous 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. Then at the end of The Battle of the Labyrinth, Dionysus gives Grover his support after learning of Pan's death, cures a traitorous demigod, Chris Rodriguez of his madness and he calls Percy by his real name (something he did very rarely to any camper) though he later denies it. Despite their relatively unfriendly relationship, Dionysus favors Percy with his judgment, help, and advice, more so than any other (demi- or full-) god in the series. This likely indicates that Dionysus acknowledges Percy with respect 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.

Hephaestus
Traditionally, Hephaestus has close ties with Percy's father, Poseidon in the terms of the Cyclopes who work for both of them. Hephaestus is particularly grateful to Percy for having discovered who was using his forge under Mt. St. Helens even though he causes an eruption that not only destroyed the intruders but also destroyed the forge itself and freed Typhon. Despite Hephaestus' gratitude and being impressed by 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 an upstart, because usually gods do not have good views on mortal heros.

Artemis
Percy is on Artemis' good side since he helped find and save her in The Titan's Curse. She even declared him a hero in the halls of Olympus itself and started calling him a man rather than a boy after he helped her defeat Atlas. Percy's friendship with Thalia, his deep loyalty, regardless of gender to others, and his respect for Zoë Nightshade has caused her to hold him in the highest regard. In The Lost Hero, she sent her Hunters in search of him, deliberately defying her father's orders. It is unknown if she is aware of what happened to him.

Hermes
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. But after the war, their relationship was mended upon Percy's counseling and sympathy for Hermes' feelings of powerlessness for Luke's fate.

Aphrodite
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.

Apollo
Apollo treats Percy like the younger cousin he is, helping him twice in The Titan's Curse to save his twin sister, Artemis. Later inviting him to ride in his sun chariot at the solstice party.

Demeter
Demeter, the goddess of agriculture and harvest has had very little interaction with Percy, having only met each other during Percy's second journey to the Underworld. However, she was one of the first gods during The Titan's Curse to vote that Percy should live.

Persephone
Percy only met Persephone twice, but both times he came off worse. In the chapter "Percy Jackson and the Sword of Hades" in The Demigod Files, Persephone tricked Percy, Thalia, and Nico into rescuing Hades' new sword, though she herself commanded its creation. When Percy finds out that this happened, he tells her, "Get lost, before I throw you in the Lethe." In The Last Olympian, Persephone is considered by Percy to brave and beautiful, 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.

Hestia
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 Box. His reason for doing so was that, "Hope survives best at the hearth."

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.

Iapteus
He is the only Titan that is on the good side with Percy. In The Sword of Hades (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. Now he assists Percy whenever he requires his assistance.

Hyperion
He and Percy have a similar hateful relationship. He and Percy fight, and he easily got furious; Percy had a mini-tornado around him, extinguishing Hyperion's light. Soon, the satyrs' magic transformed him into a tree in The Last Olympian.

Atlas
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. When Nico Di Angelo spies on the titans, Atlas could be heard shouting to be free so he could fight in the war.

Zoë Nightshade
Zoë is the daughter of Atlas. At first she did not like Percy, but then she came to respect him, saying that he was nothing like Hercules (who betrayed her), and deserved Riptide. She was injured on Mount Othrys, the Titans' base, and is transformed into a constellation named 'the Huntress' after her death by Artemis, as Zoë is part of the Hunt.

Prometheus
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.

Nico di Angelo
Nico has the ability to annoy Percy Jackson, his cousin, quite easily. He does this in The Titan's Curse by asking Percy several questions ("At this point, I was ready to stick the kid in a meat-flavored sack and throw him to the wolves."), in The Last Olympian by leading Percy to his almost demise, and in The Son of Neptune by not telling him he previously knew him ("Percy was anxious to find Nico for his own reasons- to wring the kid's neck for having pretended he didn't know Percy when he first came to camp."). They have a brother-like relationship, and Percy feels responsible for him.

Octavian
When they first met, Octavian was suspicious about Percy thinking that he's a spy for the Giants. 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 him if she gave him a signal.

Grover Underwood
Grover and Percy have been best friends since they were in middle school and at the time Percy would protect him from bullies and others that would pick on him. Grover is also the one who helped Percy to get to Camp Half 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 as she is his Girlfriend and true love) 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 has had all the Satyr's looking for Percy when he vanished in The Lost Hero.

Thalia Grace
They first meet at the ending of The Sea of Monsters when she was turned back into a human with The Golden Fleece, Introducing herself as the daughter of Zeus. Their relationship is that of a Love-Hate Relationship that a brother and sister would have during The Titans Curse, even going as far as fighting with their elemental powers, but at the end Thalia considers him a friend, showing him this when she hugged him after she joined the hunt and became a huntress of Artemis stating "I am honoring a friend." During The Titan War, she and the other hunters aided Percy and Camp Half-Blood and made lunch plans with him and Annabeth after the war was over. During The Lost Hero, Thalia is sent by Artemis to search for Him and has became very worried for his well being showing that they still have a strong friendship together.

Chiron
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.

Luke Castellan
At the beginning of the series in The Lightning Thief, Percy thought that Luke 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 to 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).

Clarisse
Clarisse 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). She later learns that Percy beat her father, causing her and her cabin to dislike Percy. The 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.

Trivia

 * Percy's birth date, August 18, wasn't revealed until the book, The Ultimate Guide. Throughout previous books he stated that "he never advertised the date because it fell right after camp ended."

 * It is also notable that Percy is horrible at archery as shown in The Battle of the Labyrinth, The Lightning Thief and The Demigod Files,but he has improved,as shown "he has stopped shooting his own teammates."
 * Percy seems to have done many things previous demigod heroes and mortals have such as: Slay the Minotaur (twice, once in The Lightning Thief, and later in The Last Olympian) like Theseus did, kill Medusa like Perseus did, get the Golden Fleece like Jason did, battle and defeat the Nemean Lion like Hercules did, visit the Garden of the Hesperides like Hercules also did, enter the Labyrinth like Theseus also did, enter the Underworld alive (multiple times) and returned alive like Hercules did, bear the Curse of Achilles like Achilles, killed a snake as a young child like Hercules. He has fought 4 Titans and lived and and defeated two of those Titans (Artemis ultimately defeated Atlas), as well as defeat a Giant, which no other hero had accomplished other than Jason who dueled Krios and won as well as defeat a Giant.
 * Percy also follows in Odysseus' footsteps by facing the Sirens, Scylla and Charybdis, and taunting Polyphemus. He also follows Jason's quest for the Golden Fleece.
 * On the cover of The Battle of the Labyrinth he is seen opening Kronos 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 pressing a button 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 thing Percy remembers were Annabeth, the fact that he was a demigod, and that he remembered Annabeth had some vague connection with San Francisco.
 * The original Perseus went to the quest for Medusa's head to save his mother, as did Percy in The Lightning Thief.
 * Poseidon mentioned that Percy has risen above every hero, even Hercules.
 * Percy is the only child of the Big Three without any demigod siblings so far.
 * Whenever Percy senses danger, the back of his neck tingles, much like Spiderman's does when his "spider sense" acts up.
 * Percy, like Annabeth, at one point dreamed of getting his parents back together.

 * Percy often mishears what people say, and then proceeds to say what he thought they said out loud (which usually makes him look stupid).
 * Oddly, Percy seems to understand some 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 destines and are waiting for the day when they will face a monster that they cannot beat.

 * Hera told Percy that the Heroes of Olympus must come together, at that time Percy was the only demigod to be said to be a Hero of Olympus by the Olympians themselves in The Last Olympian.
