Percy Jackson

Perseus "Percy" Jackson (Περσεύς in Ancient Greek) is the main protagonist and narrator of the Percy Jackson and the Olympians series. He is a demigod, and the son of one of the Big Three, Poseidon, and mortal parent Sally Jackson. Percy is the child mentioned in the Great Prophecy, destined to make a choice that will either save or destroy Olympus. He is currently Annabeth Chase's boyfriend.

Percy is played by Logan Lerman in the The Lightning Thief film.

Percy Jackson and the Olympians
The Lightning Thief

Perseus "Percy" Jackson is introduced as a troubled 12-year-old boy who has been kicked out of every single school he has attended. His most recent one is Yancy Academy where his usual trouble seems to be worse than usual. He has few friends at the school, one of which being the satyr-in-hiding, Grover Underwood.

During a field trip to a museum, Percy is annoyed by the school bully, Nancy Bobofit, and in a fit of rage, accidentally summons water in a nearby fountain to pull her in. Mrs. Dodds, his math teacher, sees the whole scene and tells him to follow her into the museum. Suddenly, she attacks him and transforms into a Fury. Percy manages to destroy the Fury.

As Percy questions him, Mr. Brunner says he saw nothing in particular and is happy Percy found his pen. Percy runs out of the museum into Grover and asks if he saw what happened; Grover acts agitated as well. Percy arrives back at the school and hears Grover and Mr. Brunner talking about him. Deeply hurt that his favorite teacher and best friend are talking behind his back, he goes home on his own, even though Grover asked him to wait for him. Arriving home to his horrible stepdad, Gabe Ugliano and his friends playing poker. He demands money for his poker game, and though Percy denies he has any, Gabe deduces that he has change from the cab drive, and forces it from him.

His mother arrives soon afterward and tells him that they can go to his favorite beach in Montauk for the whole weekend. Percy, happy that finally something good has happened, packs his things and leaves, but not before being jeered further by Gabe. Arriving at the beach, Percy is shocked to see Grover coming to him and his mom, telling them to leave. Percy is confused, but his mother takes them both in the car and begins driving at daring speeds.

It begins to rain and Percy hears a loud growl. Percy's mom arrives at a hill and forces both boys out of the car. Percy then sees the thing chasing them is a Minotaur, who charges them. The three of them manage to dodge it, but Grover is too slow and the Minotaur charges him, but is distracted by his mother. The Minotaur grabs his mom by her neck, and she disappears in a flash of light. Percy, in a surge of power and anger, manages to defeat the Minotaur. Percy drags the unconscience Grover past the hill with Thaila's tree to Camp Half-Blood and then passes out when he reaches the porch of the Big House.

Percy also meets a future friend, Annabeth, leader of the Athena cabin, who cared for him in the infirmary and who also Percy described as "pretty" when he was unconcious. He is introduced to the other campers, who Percy learns are all demigods. Percy himself is a demigod, but no one knows who his divine parent is. He also learns that the warden of the camp is the god Dionysus, who is very unpleasent and moody and Mr. Brunner is actually the hero training centaur Chiron. After a long interval of being shown around the camp, he is introduced to Luke, the leader of the Hermes cabin.

A girl that reminds Percy of Nancy Bobofit, Clarisse, leader of the Ares cabin, tries to stick his head in the toilets, but Percy uses his powers somehow to make the toilet water to shoot at Clarisse and the rest of her gang. He apologizes to Annabeth, who also got splashed, but she is just stunned at what happened, and said nothing to him.

Later in a capture-the-flag game, Percy single-handedly defeats Clarisse and three others when he touches water. After the capture the flag game Percy hears a mysterious howling and a hellhound comes out of the forest and attacks them. Percy's injury from the hellhound heals by touching the water; then suddenly, a holograpic trident flows above Percy's head which everyone and Percy learns that he is the son of Poseidon.The woods were not stocked with hellhounds, as they are only in the Fields of Punishment, and it had to be summoned from the Underworld by someone within the camp. Soon after learning that Zeus's lightning bolt has been stolen, Percy embarks on the quest of his life with Anaklusmos, Grover, and Annabeth, an adventure that bonds them.

The Sea of Monsters
Clarisse, the daughter of Ares and long-time enemy of Percy, is given the quest to go into the Sea of Monsters to find the Golden Fleece, which has healing powers for plants, animals, and humans. Percy and Annabeth decide to go also, not just for the Golden Fleece, but for their friend Grover who is trapped in Polyphemus's cave somewhere in the Sea of Monsters. Percy and Annabeth go along with Tyson, a young Cyclops (Poseidon's son, thus Percy's half-brother) who Percy befriended at school that year. He joined them on their journey after saving Camp Half-Blood from two fire-breathing bulls. Polyphemus believes that Grover is a female cyclops and not a satyr.

As they enter the Sea of Monsters, they have to get past Scylla and Charybdis. Instead of at least trying to sail in between, Clarisse automatically goes for Charybidis and Tyson supposedly dies in Clarisse's ship. After that, Percy and Annabeth journey to many dangerous islands, and Annabeth tells Percy many things about how Thalia died and she also mentions her prophecy. Fighting their way through many other obstacles, like the Sirens and Circe's island, they join up with Clarisse, Grover, and later Tyson, and leave with the Golden Fleece.

When they return to the mortal world, they send off Clarisse on an airplane to camp alone, and Percy, Annabeth and Tyson get kidnapped by Luke. He almost kills Percy in a duel, but Percy reveals Chiron was innocent, and Chiron comes to rescue them with his strangely dressed relatives. When they return to camp, the Fleece is put on the tree. The Fleece not only revives Thalia's tree, but it brings Thalia back to her full life form. It's Thalia who appears as she looked in Percy's dreams. He remembers the dream and realizes that it is her. It turns out that this was actually Kronos's plan, done so that he would have another chance to manipulate the prophecy which governs the future of Olympus and the Olympians.

In the end, Annabeth kisses Percy on the cheek after winning the chariot race.

The Titan's Curse
The demigods, Percy, Annabeth, and Thalia rush to the rescue to find that Grover has made an important discovery: he has found two powerful half-blood siblings whose parentage is unknown: Bianca di Angelo and Nico di Angelo. A fierce battle awaits...and a surprise from a group of Hunters with Artemis, the goddess of the moon and the hunt, but that's not all that awaits them. The Titan lord Kronos has devised his most devious plot yet, and the young heroes have just fallen prey to it.

They're not the only ones in danger. An ancient monster has arisen -- one rumored to be so powerful it could destroy Olympus, and Artemis, the only one who might know how to track it, is missing. Now Percy and his friends, along with the Hunters of Artemis, have only a week to find the kidnapped goddess, find Annabeth who supposedly got kidnapped by the evil Dr. Thorn, and solve the mystery of the monster Artemis was hunting. Along the way, Grover makes a very important discovery about Pan. Also during the journey, Percy meets a mortal girl named Rachel Elizabeth Dare, who can see straight through the Mist. She helps him escape from dead warriors. While warning them about the junk yard of the gods, Aphrodite tells Percy there is a romantic future waiting for him with Annabeth.

Once at the other side of the country, they go to the Mountain of Despair to fight Atlas and Luke. Thalia was fighting Luke, and everyone else was fighting Atlas. Artemis was struggling against her bond, the weight of the sky. Percy took the sky from her and held it while Artemis and Zoë lured him back to where the sky was being held (Percy later gets a streak of grey from his experience of holding up the sky). While this was happening, Thalia was fighting Luke, and Thalia was winning. Finally, Artemis threw Atlas over to Percy. He knocked Percy from under the sky and Atlas had to hold his burden once more. Thalia and Luke were still fighting but finally Thalia made him flinch with her shield, Aegis. Later, she tries to finish him off with her spear, but Luke grabbed it and as fast as thought, Thalia kicked him to his 50 foot fall. During the battle, Zoë receives deadly injuries; she is poisoned by a Dragon, Ladon, and her father, Atlas, who made the final strike that killed her. Artemis put her out of her pain and she turned into dust. The dust flew into the stars, creating a new shape in the sky in the shape of a hunter. On Mount Olympus, Thalia becomes one of Artemis' hunters. On the way back to camp, Percy was trying to figure out how to tell Nico his sister died because of a crazed robot in the junkyard of the gods. Once at camp, Percy told Nico the horrible truth and the boy sprints into the woods. Annabeth, Percy and Grover search for Nico for a long time, but have no luck. Percy then holds the figurine of the god Bianca got for him at the junk yard. Suddenly, he realizes who Nico's dad is: Hades, Lord of the Dead. Many weeks later, Grover was drinking a lot of coffee, trying to get a connection with Pan, like he did in New Mexico. He comes running towards Percy to tell him Pan spoke in his mind. Pan only said three words, "I await you...."

The Battle of the Labyrinth
Percy Jackson thinks that freshmen orientation won't be fun, and that itself proves to be when he is accompanied by a mortal friend, Rachel Elizabeth Dare. Rachel tells Percy to leave the room when she spots the demon cheerleaders that Percy had encountered when he went in through the side of the building to ignore Rachel. As Percy leaves, he ends up having to fight the demons and runs into Annabeth Chase, a friend from camp along the way. They were supposed to see a movie together, but is upset when she sees Rachel with him because she is jealous. She takes him to Camp Half-Blood, a camp just for demigods like them. Percy finds his half-brother Cyclops, Tyson, waiting for him in his cabin.

Quintus, the new swordsmen teacher, is accompanied by Mrs. O'Leary, a hellhound that develops a soft spot for Percy. During a game that Quintus made up, Annabeth and Percy go through the rocks of Zeus's Fist and are stuck in a dark room. Annabeth is offered the quest she has been waiting for since age 7: She must enter the Labyrinth, find Daedalus, and get Ariadne's String before their arch enemy, Luke Castellan, does.

Luke has been planning on burning down Camp Half-Blood, and using the Labyrinth to get there guided by Ariadne's String. Annabeth gets her prophecy from the Oracle: "You shall delve in the darkness of the endless maze; the dead, the traitor, and the lost one raise; you shall rise or fall by the ghost king's hand; the child of Athena's final stand; destroyed with a hero's final breath; and lose a love to worse than death." She withholds the final line, though, until much later in the book. Annabeth takes Percy, Grover, and Tyson along with her. Together, they enter the maze. They are accompanied by Hera, who tells that Percy knows the way.

When they take a wrong turn throughout the maze they run into Nico, son of Hades. Nico is accompanied by King Minos, who tries to convince Nico to and that they are not his friends. Once they get out, Percy and the others run into a sphinx-run quiz show. Also, once they return to camp, Hephaestus has them travel to one of his forges. Percy gets lost in the inner depths of Mt. St. Helen's while battling fierce water demons. Before parting with Annabeth, she kisses him for luck because she thinks he is going to die, and vanishes under her cap of invisibility.

Percy blasts out of Mt. St. Helens while escaping and ends up falling into Ogygia. There, he meets Calypso, a young girl whom Percy thinks is much prettier than Aphrodite herself. Percy must leave the island and Calypso (who has fallen in love with him) behind. When he finds Annabeth again, Annabeth thinks Percy is dead but is surprised to see him and starts hugging him fiercely until she realizes she is making a big scene in front of all of the other campers. Then Percy realizes that he does know the way, a mortal girl with clear sight must guide them. Once they are accompanied by Rachel again, they run into a wide arena, where Percy battles a dracaena and the demigod Ethan Nakumura. Sparing Ethan, Percy challenges his giant half-brother, Antaeus, that is accompanying Luke. Percy kills him by luring him off the ground, as his mother is Gaia.

When he finds Annabeth and Rachel again, Rachel leads them straight to Quintus, who tells them that he is Daedalus; he reveals that Luke got there first. He also says that Rachel is better and more accurate than the string. Monsters then attack the workshop, dragging Nico Di Angelo in chains. Percy, Rachel, Annabeth, and Nico escape and leave Daedalus to fight the remaining monsters. They find another entrance and enter the maze once again. Once they navigate through the maze, Percy hears the Titan Lord speak to him. Taking Annabeth's invisibility cap, he goes into the room and opens the coffin.

There, not fully formed, is Luke. As much as Percy hated him, Percy did not draw Riptide. He finds the demigod whom he spared earlier in the maze, Ethan. Ethan joins the Titan's side and Luke/Kronos comes to life. Percy barely escapes, thanks to Nico Di Angelo. While they were going through the Labyrinth, they meet up with Tyson and Grover. Together, they all find the wild god Pan, who tells them he is dying. As his spirit dies, it goes into the mouths of each of them, and it seems that Grover got a little bit more than the rest. Rachel leads them to New York, where Pegasi take Percy, Annabeth, Grover, Nico and reluctently, Tyson. The five of them had to leave Rachel behind, because she is full human.

They go to help the camp ready for the Titan army's arrival. Battling side by side are Annabeth and Percy. Percy and Annabeth fight an evil monster, along with Briares's help. Grover, in a panic, screams so loudly that it scares the Titan army back into the Labyrinth. Grover's Dryad girlfriend, Juniper, insists that it was Pan's wild scream that had scared the Titan army the first time. As Percy gets up, Daedalus comes and tells them that the Labyrinth is tied to his life.

The child of Athena (Daedulus) dies, and so does the Labyrinth. Percy, Annabeth, and the other uninjured campers take the wounded to the Big House. Percy decides to leave camp and go celebrate his birthday with his mom. Two surprising visitors stop by while Percy, Tyson, his mom, and Paul Blofis (Percy's mom's boyfriend, and soon to be husband) are celebrating. First, Percy's father Poseidon comes and tells him that he fears Luke/Kronos is only temporarily defeated. Finally departing with Poseidon, Percy decides to go to his room to plant the garden he had earlier promised Calypso. As he does, Nico di Angelo stops by and tells him that he needs to tell Percy things about how they might be able to stop the Titan army. Percy then invites him for cake.

The Last Olympian
Percy is driving Paul Blofis's Prius with Rachel. Rachel is flirting her way into a relationship when they are interrupted by Beckendorf and Blackjack landing on the hood of the car. Rachel briefly kisses Percy and Beckendorf makes a joke about not telling Annabeth about that little scene, and Percy responds by saying, "Oh gods, don't even think about it." Then Beckendorf tells Percy that it's time to initiate their plan to destroy the Princess Andromeda, Luke's demon cruise ship inhabited by Kronos' Army. While they are setting the bombs to blow up the ship, some Telekines and Dracanae attack. Percy distracts them to give Beckendorf time to arm the explosives. He battles Kronos, but Beckendorf is captured. Because the explosives have no timer and Beckendorf has the detonator, he sacrifices himself to help Percy escape and carry out the plan.

Percy loses consciousness in the water and drifts to Poseidon's palace under the sea where he meets Tyson and other relatives. Poseidon is fighting Oceanus and his army, aging rapidly due to the state of the sea. Percy wants to stay and fight, but he must return to Camp Half-Blood to relay news of what happened on the Princess Andromeda to the campers. Chiron and Annabeth agree to show him the Great Prophecy, and after reading it he learns that his fate is to make an important choice and to die by a cursed blade. Percy is all keyed up for a while afterwards until a confrontation with Annabeth, when she calls him out as a coward. As he contemplates his fate, Nico returns to discuss the secret plan introduced in ''The Battle of the Labyrinth. ''He wants Percy to bathe in the River Styx to become invulnerable like the hero Achilles.

To do so, Percy Jackson must first discover how Luke could do it and they go visit his mother, May Castellan in Connecticut, where they find her insane and unstable. She does tell that Luke came and asked her for her blessing for something that he needed to do. They also meet the goddess of the hearth, Hestia, who shows Percy visions of the destruction being caused by Typhon. Percy and Nico visit Sally and Paul Blofis back in the city, to get her blessing. She insists that Percy is now his own person, and that she has to let him go. Nico leads Percy to the Underworld, where Hades reveals that it was all a trick to make Nico the child of the prophecy. Nico rescues Percy, though seems to have lost his trust, and takes him to the Styx, where he is submerged in the water and becomes invulnerable, but for one spot on his lower back.

The war begins and Percy leads the group of demigods into a sleeping Manhattan to battle monsters and demons, while the gods are battling the monstrous Typhon in the east. Rachel arrives, revealing that she has had a vision which read, "Perseus, you are not the hero.' It will affect what you do."

Annabeth is able to convince Luke to resurface. She reminds him of his promise that he would protect her, and asks Percy to give him the knife so that he can end everything. Percy hands over the knife, discovering he was not the hero after all, but his choice to give it to Luke was the decision he had to make. Kronos is blown to dust and scattered by the wind, and Luke dies a hero's death. Through deaths and betrayals, the demigods stand victorious. Percy is given the gift of becoming a god, but declines due to his love for Annabeth, to whom he is finally able to confess his feelings for. He instead requests that the gods claim their children by the age of thirteen and that Camp Half-Blood construct cabins for the minor gods and Hades. When he comes back to Camp Half-Blood, he finally expresses his feelings for Annabeth and they kiss twice, the first time in Camp Half-Blood's mess hall, and the second time being underwater, the latter which he describes as 'pretty much the best underwater kiss of all time.' At the very end of the book, he and Annabeth share a moment of bliss as they race toward the road down Half-Blood Hill back into the mortal world, not looking back at Camp Half Blood.

The Lost Hero
In the preview chapters of The Lost Hero, it is revealed that he and Annabeth are offically dating, and that he is the "Lost Hero." When Annabeth and Butch arrive in a chariot with the intention of finding Percy, rather than retrieve Jason, Leo, and Piper, Annabeth yells at the sky, saying," What do you want from me? What have you done with him?" Indicating a god might've abducted Percy. Annabeth was told to find 'A guy with one shoe'.

Personality
Percy is usually portrayed as a brave and righteous person, often willing to risk his life to save his friends, strangers, even his enemies. Athena tells Percy that his fatal flaw as of The Titan's Curse is willing to risk his life for his friends, which is very dangerous for the hero of the prophecy. Percy seems to dislike titles being given to him as he always tells Blackjack and the other pegasi not to call him "boss" or "lord" whenever they talk to him. Despite not being very popular at school, Percy's compassion and good nature has caused several girls to develop feelings for him, including Annabeth (who he starts going out with at the end of the fifth book), mortal girl Rachel Elizabeth Dare, and the daughter of Atlas, Calypso. His fatal flaw, like what Athena told him, is that he will sacrifice anything to save anyone that he loves. Percy is very often sarcastic, but moody, and loves his family and friends. Percy's favorite food is "blue" cherries. (Blue because his mom always makes food which is blue.)

Special Abilities
Percy, like most demigods, has these disabilities and traits:


 * ADHD, which actually is heightened alertness that keeps half-bloods ready and alive for battle.
 * Dyslexia, since his brain is hard-wired for reading Ancient Greek instead of modern languages.
 * Percy has clairvoyant dreams, causing him to watch events in distant locations as an out-of-body experience. This is a general feature of demigods, but becomes even more intense during times of strife and when events are in motion. Percy has an inherent knack for seeing otherwise hidden things thanks to his unpredictable, changeable nature, inherited from Poseidon.

Children of the "big three" (Zeus, Poseidon, or Hades) are more powerful than demigods of the other Greek gods and goddesses. Hence, Percy has a wide range of abilities.


 * Percy is a naturally talented swordsman, often able to hold his own against larger, stronger, and more experienced opponents.
 * Percy possesses incredible physical strength. He tore a horn off the head of the Minotaur (because of the rain making him stronger, see hydrokinetic abilities point one), and was able to bear the weight of the sky, the curse of Atlas, and was able to strangle a snake with his bare hands.This is rather strange, because Hercules, the son of Zeus did the latter two of these deeds, however, Percy is the son of Poseidon.
 * In The Last Olympian, Percy bathes in the River Styx (like Achilles), making him nearly invulnerable except in one weak point (the small of his back) and also granting him increased skill, strength, and puts him into a frenzy in battle.
 * Percy has a psychic connection with Grover called an empathy link.

Aquatic/hydrokinetic abilities
Percy has numerous powers specifically connected to the domains of Poseidon: seas, horses, sea creatures, storms, and earthquakes. His water-related abilities tend to be stronger in sea water than in fresh water.


 * Upon contact with water, Percy gains a disproportionate amount of strength, combat skill, and speed-but only for a short time unless he is standing or immersed in water.
 * Percy can control large volumes of water with great force (hydrokinesis). For example, he can redirect rivers, create currents to push boats or himself, or even increase surface tension to the point where it is firm enough to stand upon.
 * Percy can summon localized hurricanes and other storms, complete with lightning and wind, as his father is the god of storms. It is unclear if Percy can manipulate the wind and lightning into offensive attacks (which will make a good example of Thalia Grace's electrokinetic and aerokinetic abilities).
 * Percy can breathe underwater. He is unharmed by water pressure of any amount, or by falling from great height into water.
 * When Percy is underwater, he stays dry unless he consciously forces himself to become wet. When Percy touches objects underwater, they become dry.
 * Percy can create seawater with no effort with things that used to be in the sea (such as petrified seashells, as seen in The Battle of the Labyrinth)
 * Percy can communicate telepathically with sea animals, most of whom also obey him and treat him with respect.
 * Percy can communicate with equine animals (horses, zebras, pegasi, etc.), as his father created them out of sea foam. They tend to treat him with some deference and work to accommodate him; a notable exeception are the flesh-eating horses in The Battle of the Labyrinth.
 * While at sea, Percy has perfect bearings on his exact coordinates. (Longitude, Latitude, knots)
 * Percy can telekinetically control all things that are connected with the sea (He has shown to be able to control boats).
 * Percy can sense where objects are underwater.
 * Percy can communicate with children of Poseidon, such as Cyclopes, underwater.
 * Percy is very resistant to burning, and is even able to survive while immersed in magma for a short while because of the "power of the ocean" inside of him.
 * Percy can release the oxygen diffused in water and force the surrounding water to recede, making an air bubble so his friends with non-hydrokinetic abilities can breathe.
 * Percy can control ocean currents to propel him at great force underwater, or even up into the air, as he does in his duel with Ares.
 * Percy can harden water (without freezing it) to form shields, and in the movie made a trident of hardened water. It is quite possible that he could use this skill to other purposes, combat or otherwise.
 * Percy has a healing factor when standing or immersed in water, which is capable of mending serious wounds and curing him of poisoning. In the film he used this skill to heal other people.
 * Percy can create earthquakes and cause volcanic eruptions (As seen in The Battle of the Labyrinth). He might also be able to control the Earth and earthly resources(geokinesis), but to a lesser degree than the children of Hades.

Magical Items

 * Minotaur Horn, he obtained this when he killed the Minotaur after it supposedly killed his mother, Sally Jackson.
 * Anaklusmos (Called Riptide in English), made with celestial bronze, given to him by Chiron to fight the monsters he'd meet. Used to be owned by Hercules who got it from Zoe Nightshade. In the movie Riptide can deflect blasts from Zeus' lightning bolt.
 * Medusa's head. He had cut it off and sent it to Olympus. He received it at the end of the first book. Sally Jackson uses the head to dispose of Gabe Ugliano, and disposes of the head.
 * Stygian ice whistle, is a special dog whistle that is made of unmeltable ice that was cooled in the River Styx. It's used to call hellhounds and shatters after it is blown into. Percy used one to call Mrs. O'leary when they were in trouble while fending off an army of monsters in The Battle of the Labyrinth.
 * A wristwatch which turns into a shield, given to him by Tyson. It was smashed by Dr. Thorn in The Titan's Curse. Tyson came back and fixed it in the beginning of the next book, but it was left behind in San Francisco when Percy sacrificed it to save Tyson, Annabeth, Grover and himself.
 * Nemean Lion 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 to stop Kronos' forces on boat.
 * Chameleon armor, he used this in a game of capture the flag in the short story of the bronze dragon.
 * Hermes' multivitamins, these multivitamans make the person who ate it to be immune to nearly any attack, which was used during the Sea of monsters.
 * The Golden fleece, after Annabeth was wounded by Polyphemus used the golden fleece to heal her.
 * 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.
 * Thermos of winds, this was used by Percy and Annabeth in the Sea of monsters to, escape the Princess Andromeda and Charybdis.
 * Magical Pearls, these pearls can transport a person to the sea when smashed.
 * Moonlace, a flower that can glow in the dark, and can also grow in moon light.
 * Javelins, these aren't normal javelins, because they have a grappling hook, and a explosive setting.
 * Daedalus' wings, stolen in a skirmish in the center of the labyrinth.
 * Winged Trainers, in the book the wings spring out when the wearer says Maia, Percy gave them to Grover. In the film he used these to retrieve a magical pearl.
 * Sheild generating gauntlets, used and seen in the movie, which was oringinally owned by Luke, and it contained Zeus' master bolt.

Fatal Flaw
In The Titan's curse, it is said by Athena that Percy's fatal flaw is personal loyalty. She said that Percy would risk the world to save a friend. He tried to argue but realizes she is right. Athena was obviously not pleased that her own daughter was an example of this. Kronos exploited this weakness in The Lightning Thief, The Sea of Monsters and The Titan's Curse.

Romance
Calypso: After Percy is stranded on the island Ogygia, he is healed by a girl named Calypso. She is stranded on the island after supporting her father, Atlas, in the the First Olympian War and is to live on the island forever. She asks him to join her and live with her forever but he turns her down, even though it could save him the trouble of the prophecy (The prophecy states that the next child of the Big Three to turn sixteen decides the fate of Olympus). Calypso was in love with Percy but even though she was beautiful, Percy never actually 'loved' Calypso. In The Last Olympian he also requests from the gods that she be freed from her captivity on Ogygia because she is peaceful.

Rachel: Even though Percy is not known to like Rachel romantically, it is known that she likes him. In The Last Olympian she says, 'And so. . . hypothetically, if these two people liked each other, what would it take to get the stupid guy to kiss the girl, huh?'. However, Beckendorf and Blackjack landed on the hood of Paul Blofis' Prius before he could answer. Rachel kissed him anyway though. Percy was unsure about having a crush on Rachel, as he never truly admits it. However, Percy's growing love for Annabeth never stopped so Percy didn't develop a true relationship with Rachel. Percy always knew deep down that he never really loved Rachel. 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. This was because she had taken on the spirit of the Oracle, which meant she would not be able to date. And Percy is kind of not very happy about this when Rachel said this on Olympus because he hadn't even been very close to her and it seemed like Rachel dumped him. Rachel always seems to 'ruin' everything between Annabeth and Percy, which Percy is clueless to.

Annabeth Chase: Annabeth is protrayed in the series as Percy's primary love interest and his eventual girlfriend. When Percy first wakes up in The Lightning Thief, he describes her as a "princess, with golden curls". Percy and Annabeth disliked each other when they first met (only because their parents Athena and Poseidon have a rivalry) but soon grow fond of each other. Aphrodite has told him that they will have a 'tragic love life'. Annabeth has kissed him four 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, The Last Olympian in the dining area of Camp Half-Blood, prior to all other campers throwing them in the canoe lake in The Last Olympian, and finally underwater also in the The Last Olympian. Also, Annabeth is known to be jealous of Rachel, the clear-sighted mortal girl because Percy spends a lot of time hanging out with her.

The Sea of Monsters - At Meriwether Prep., Percy notices that he'd missed Annabeth probably more than he wanted to admit

- After Percy and Annabeth won the chariot race and Annabeth talks about Tyson, she plants a kiss on Percy's cheek.

The Titans Curse - Aphrodite comes to meet Percy and asks why he is on the quest. Percy hesitated but finally says that Annabeth is in trouble. Aphrodite tells Percy that she is going to make some difficulties and indecisions for him (and soon Percy meets Rachel at Hoover Dam).

- Up on Olympus for the winter solstice council meeting, Artemis suggests Thalia to be her new lieutenant. Percy thinks Artemis is asking Annabeth to be the lieutenant, so he becomes pale and tells her not to do it under his breath. He murmurs, "Look, I need to tell you something. I couldn't stand it if... I don't want you to..." And Annabeth is just puzzled.

The Battle of the Labyrinth - Under Mt. St. Helens, Annabeth thinks Percy is going to die and she kisses Percy. She tells him to be careful, puts on her New York Yankees invisibility cap and vanishes, making Percy want to sit there for the rest of the day, staring at that lava, and trying to remember what his name was.

- After returning to camp from Calypso's Island, Percy finds Annabeth burning his shroud. When Annabeth notices him, she hugs him fiercely. Annabeth pushes him away when she realizes she was making a scene in front of the campers.

- When Percy suggests Rachel to join him and Annabeth to the Labyrinth, Annabeth becomes very jealous of Rachel. Percy doesn't seem to know why Annabeth is acting like this, and Rachel mutters that boys are totally blind.

The Last Olympian - Annabeth seems to have hinted quite a bit that she is interested in Percy, and it seems to not matter to her that Athena does not approve of them even as just friends. In the Last Olympian, when Percy and Annabeth are inspecting the cabins, Percy finds himself staring at Annabeth and he sees that Annabeth is starting to look seriously beautiful, not only cute.

- When Percy bathed in the River Styx, he is supposed to envision the one thing that keeps him tied to the mortal world. He thinks of Annabeth pulling him out of the water at Camp Half-Blood's canoe lake.

- Before Percy and Annabeth go to battle the Titan army, Percy asks Annabeth for a kiss for luck, but she replies, "We'll see, Seaweed Brain."

- Throughout the book, Annabeth and Percy repeatedly express their worries and cares for each other before going into battles, such as when Percy goes to the East and Hudson rivers and Annabeth warns him, "Just be careful. I don't want anything to happen to you." Then quickly adds, "I mean, because we need you for the battle."

- When Percy is offered immortality by the gods for saving Olympus, he looks over at Annabeth and recognizes the same fear in her eyes that Percy had while thinking Annabeth was going to join the Hunters in the Titan's Curse. He turns the offer down, and Annabeth put her hands over her mouth, her eyes shining and silently crying tears of joy.

- On Mount Olympus, when Luke asked Annabeth if she'd loved him, Percy realizes that the only thing that really mattered to him was that Annabeth was alive, even though the world was collapsing.

- Later at camp, he confides to her the vision he had at the Styx and the reason he turned down immortality. He looks over at her and she was smiling. He tells her that she is not making it easy, but Annabeth indicates that she will never make life easy for him, and kisses him. Percy feels like his brain is melting right through his body.

- But then Clarisse and a couple of her friends come out from hiding. She says, "the lovebirds need to cool off" and then they plunge Annabeth and Percy into the water. Percy makes an air bubble and they have 'the best underwater kiss of all time'.

After the last two weeks of camp, Percy and Annabeth are seen together running down the hill from Camp Half-Blood. For the first time, Percy did not look back.

Sally Jackson
Percy loves his mother Sally, and goes as far as to have her jerk of a husband, Smelly Gabe (as Percy nicknames him), turned to stone to make her happy. He even considered giving his life for her when Hades took her hostage, hinting towards his fatal flaw.

Poseidon
While he admires what he's heard about his absent father, he also feels abandoned for many years. When he learns that his father is Poseidon, he is resentful at having been ignored all his life, but grows to realize that such is the life of a Half-blood. Though they have rarely met, Percy loves his father very much and he learns throughout all of the books that Poseidon loves him and thinks of Percy as his 'favorite son'.

Paul Blofis
Percy is at first wary of Sally's new boyfriend, Paul Blofis, but eventually warms to him, too. Percy is very happy to have Paul as his step dad. In the end Sally Jackson gets married to him, as Percy mentioned Paul as his stepdad rather then "his mom's boyfriend". Percy and Poseidon at first misprononce Paul's name as "Blowfish".

Tyson
During the series, he meets and grows to love his half-brother Tyson. He and Tyson have gone on many adventures together, and they love each other a lot. Even though Percy wasn't sure he liked him as a brother at first.

Gabe Ugliano
Percy hated his former stepfather a lot. When he was young, he called his stepfather "Smelly Gabe", partly because he smelled so bad. Percy threw it in several times while referring to Gabe in the Lightning Thief. Whenever his mother wasn't around he had a choice: give Gabe money, or get beat up. Percy hated him to the point where he wanted him turned to stone (with the head of Medusa). Percy, however, knew that his mom would have to make the choice for herself. He gave her the head, and within a week, she mailed Percy a letter saying how much money she got for selling a statue she called, "The Poker Player".

Relationship with the Olympian Gods

 * Poseidon: Percy is on good terms with Poseidon mainly because he is his son. At the end of The Battle of the Labyrinth, Poseidon says that Percy is his favorite son. Poseidon even forgives Percy for sitting on his throne in The Last Olympian. Poseidon states that not even Hercules is as good a hero as Percy, which supports Poseidon's admiration for Percy.
 * Zeus: Zeus has mixed feelings for his nephew Percy. He is upset over Percy's birth because it violates the pact that he, Poseidon, and Hades made after World War II to not bear any more children, but is happy when Percy returns his Master Bolt to him in The Lightning Thief. He also allowed Poseidon to talk to Percy after receiveing his bolt. During the winter solstice in The Titan's Curse, Zeus votes to let Percy live, however it was also tied to the fate of his daughter, Thalia, as well. However, Thalia had agreed to become one of Artemis' Hunters before this, so it is possible that he did vote in only Percy's favor. In spite of all of this, Zeus tells Percy that if he ever finds him in his realm (the sky), he will strike him down. After Percy fights in the battle at the end of The Last Olympian, Zeus offers Percy godhood for saving Olympus from the Titans.
 * Hades: Hades also has mixed feelings about Percy. Percy accused him of stealing Zeus' Master Bolt when he wasn't aware Luke had stolen it. Later however, he returns to Hades his Helm of Darkness and clears his name. In The Last Olympian, Hades is shown assisting Percy during the war, even talking with his son, Nico, who also has a decent relationship with Percy afterwards. When Percy rejected immortality, Hades is shown casually addressing him, with none of the malice that he normally shows.
 * Ares: The god of war despises Percy. His hatred for his Percy only intensifies when he defeats him in a 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 saying that when he needs his sword the most, it will fail him. He only goes along with granting Percy godhood because he can fight him multiple times and Percy will continue to return.
 * Athena: Athena disapproves of Percy's 'friendship' with her daughter Annabeth Chase because of the historical rivalry between herself and Poseidon, even though Percy has not done anything against her. In The Titan's Curse, she guided him at the Hoover Dam. However in the same book, she also voted that he be destroyed. In The Last Olympian, Athena is on neutral terms with Percy, with the exception of his relationship with Annabeth.
 * Hera: Hera neither likes nor dislikes Percy. Percy and Annabeth both disagree with her views of families having to be perfect, siding with her husband, even though Hera helped them numerous times in the book. Percy also insults her by mentioning Thalia, one of Zeus' children not borne by her, whom Hera historically despises, along with Hercules. She swears to make Annabeth regret her decision, much like Ares did to Percy, but it is not directly stated whether she included Percy in this statement. She makes Ares write a thank you letter to Poseidon for saving Olympus, revealing that she may care for him.
 * Dionysus (aka "Mr. D"): Percy has been on Mr. D's bad side from the very second they met, however Mr. D dislikes all demigods. Percy does not like Dionysus very much either because he constantly antagonizes campers by never calling them by their real names. On the other hand, he saves Percy's life in The Titan's Curse. One of the other reasons he may dislike half-bloods is because of the way they treat mortals; he mentions Theseus and Ariadne, Jason and Medea, and alludes to Hercules and Zoe Nightshade in The Titan's Curse, mentioning how the former in all three cases used and later abandoned the other. However, at the end of the Battle of the Labyrinth, their relationship comes to better terms. Dionysus believes Grover's news of Pan death, disbands the Council of Cloven Elders when they are at a tie, and cures Chris Rodriguez, a previous traitor half-blood, of the madness he obtained in the Labyrinth. Most shockingly, he calls Percy by his real name, although he later denies this. Although Dionysus denies this, he favors Percy with his judgment, help, and advice, more than any other (demi)god in the series. This may be proof that Dionysus is acknowledging Percy, and that their relationship is improving.
 * Hephaestus: Hephaestus is grateful to Percy for having discovered who was using his forge under Mt. St. Helens, even though he causes an eruption that destroyed the forge and awakened Typhon, but also dispersed and/or killed the users. At the end of the 5th book, Hephaestus said that Percy had done a 'Pretty bang up job, mostly'. Historically, Hephaestus and Poseidon have close ties in the terms of the Cyclopes who work for both of them.
 * 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. His respect for Zoë Nightshade, and his deep loyalty, regardless of gender, has also improved her view of him immensely.
 * 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 took a turn for the worse after realizing that Percy could not save Luke. But after the war, their relationship was mended upon Percy's counseling and sympathy of Luke's situation and prophecy as well as how powerless Hermes was.
 * Aphrodite: The goddess of love and beauty is on Percy's good side, probably because she is intrigued by Percy's desire to save Annabeth. She expressed an interest in their relationship, meaning that she plans to meddle with it in some way. She also said she would make Percy's love life hard, just because she likes him. The way she meddled with it was by making Percy meet Rachel and causing him to be confused about Annabeth. She was playing with him all along, of course, by liking a "nice tragic story."
 * Apollo: Apollo treats Percy likes a younger cousin (which he is). The sun god helped Percy twice in The Titan's Curse so that they could save Artemis, his sister.
 * Demeter: This godess of wheat and farming has a poor relationship with Percy due to Percy's lack of respect towards her. Demeter says that he should eat more cereal.
 * Hestia: Percy and Hestia have a good relationship. In The Last Olympian, Percy entrusts her with Pandora's Pithos that contains the spirit of hope, Elpis, saying that "hope is best kept by the hearth". She also helps him and shows him the stories of Luke. Hestia is a very important character in The Last Olympian because it was named after her (She called herself the last Olympian).

Relationship with Titans

 * Kronos: Kronos is Percy's archenemy. Being a son of The Big Three, Percy is related to Kronos, despite their murderous feelings for each other. "Being the son of Poseidon and all, I guess that makes him my grandfather." are Percy's feelings on the matter of Kronos being his grandfather. He thought it so strange he dismissed it completely. Nevertheless, Percy is Kronos's grandson. He has tried to recruit Percy to his cause several times, with no success. No one speaks of this after he is blown to dust, probably because they have never considered the thought.
 * Iapteus: This is the one and the only Titan Percy is on good terms with. In "The Sword of Hades" in the Demigod Files, Percy tricks him into crashing into the River Lethe wiping his memory clean. He emerges believing he is a man named Bob. Now he assists Percy whenever he requires his assistance.
 * Hyperion: He and Percy have a similar hateful relationship. 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. He managed to get Luke to carry it so he could join the war, who tricked Annabeth to carry it, who then had Artemis take the burden so Annabeth did not die. Percy managed to trick Atlas back into wearing the sky again, so it is heavily implied that Atlas hates Percy, like most of the Titans.
 * Zoe Nightshade: As Zoë is the daughter of Atlas, she is a Titan herself. At first, she didn't like Percy, but then came to respect him, saying that he was nothing like Hercules, and deserved Riptide. She was injured on Mount Orthys, the Titans' base, and is transformed into a constellation after her death by Artemis, as Zoë is part of the Hunt.
 * Prometheus: Prometheus and Percy have mixed feelings for each other. Although Percy regards him as "a slimy worm", he becomes more respectable of him when he shows Percy a vision of Hermes lecturing Luke. It is unknown if they meet again, and if they do meet again, their probably under better terms.
 * Calypso:Calypso is percy's ex-love interest and friend. She is another one of the Titans that Percy is on good terms with.He falls on her prison island home of Ogygia in The Battle of The Labyrinth.

Film
In the film, The Lightning Thief, Percy is played by Logan Lerman. His character's age has been increased from 12 to 17 to appeal to older viewers.

Trivia

 * Percy's birth date wasn't revealed until the very last book, The Last Olympian. Throughout previous books he stated that "he never advertised the date because it fell right after camp ended." His birthday is on August 18th.
 * Percy's real name is Perseus. His mother named him this because Perseus was one of the only demigods to have a happy ending. He also is, like in the original myth, the one to slay Medusa.
 * Though Percy has said many times in the series that he dislikes Clarisse, in The Demigod Files, he reveals that he really does care about her, Clarisse vice-versa, and considered her as a friend.
 * It is also notable that Percy is horrible at archery as shown in The Battle of the Labyrinth and The Lightning Thief.
 * Percy seems to have done many things previous demigod heroes 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 the Nemean Lion like Hercules did, visit the Garden of the Hesperides like Hercules also did, enter the Labyrinth like Theseus also did, and bear the Curse of Achilles.
