Percy Jackson

Perseus "Percy" Jackson (Περσεύς in Ancient Greek) is the main character and narrator of the series. He is a demigod, son of the god Poseidon, one of the Big Three, making him a very important and powerful demigod. He is currently the only known demigod child of Poseidon. His mortal parent is Sally Jackson. As the son of Poseidon, he has the ability to control water, an ability which has an incredible variety of uses. He falls in love with Annabeth Chase and they kiss in The Battle of the Labyrinth and The Last Olympian.

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

History
Percy Jackson was raised by his mother, Sally Jackson, and was an only child. When he was 12, he went to a boarding school called Yancy Academy, where he met a Satyr, Grover. On a school field trip, one of Percy's teachers, Mrs. Dodds, turned out to be a Furry, and attacked him. Just as Mrs. Dodds revealed her true monstrous form, Mr. Brunner, Percy's favorite teacher, gave him a pen which turns into a sword (later on mentioned as Anaklusmos (Riptide). Percy won a close victory over Mrs. Dodds, but afterward no mortals remembered that she ever existed. Instead, the Mist convinced them that a perky Mrs. Kerr was their pre-algebra teacher since Christmas.

Percy is discovered to be the son of Poseidon and he is blamed by Zeus of stealing his master lightning bolt, and says if it is not returned by the summer solstice there will be a war. Percy goes on a quest with Annabeth Chase and Grover Underwood to find the master bolt. Later, after a long and tedious journey, and they discover the thief was Luke, and that Ares had taken it from him.

The Sea of Monsters
In The Sea of Monsters, Percy goes back to camp in which he discovers Grover is missing from a dream,Thalia's pine tree has been poisoned, Chiron got the blame for doing it and got fired by the gods, and the camp borders have been weakened. Clarisse is assigned to embark on a quest to get the Golden Fleece to save the tree by the new camp director, Tantalus, but Percy, Annabeth, and Percy's newly discovered Cyclopes half brother, Tyson, sneak out of camp to rescue Grover with a little help from Hermes to get the it. Percy, Tyson, Annabeth, and Clarisse work together to defeat Polyphemus, the cyclops guarding the Fleece and the one who took Grover hostage mistaken for a lady Cyclopes. In the end, the Fleece is brought back to the camp where it is used to heal Thalia's tree. It also heals Thalia and releases her from the tree.

The Titan's Curse
In The Titan's Curse, Percy, Annabeth, and Thalia go to a military school (Westover Hall), where Grover has found two new half-bloods, Bianca and Nico di Angelo. In the battle, Annabeth jumped onto the back of a manticore, who jumped off a cliff. Percy, Grover, Thalia, two of Artemis' hunters, Zoë Nightshade and Bianca, must go on a quest to save Artemis(who has been captured by the General Atlas), however Percy cares more about saving Annabeth.

The Battle of the Labyrinth
In The Battle of the Labyrinth, Percy, Annabeth, Grover, and Tyson go into the Labyrinth on a quest led by Annabeth to foil Luke's plan. In the end, they require the help of Percy's mortal friend, Rachel Elizabeth Dare, to help them find Daedalus's workshop. Then, Luke Castellan is discovered to have hosted the Titan lord's body, which was Luke's role the whole time in Kronos's plan. After arriving at camp, camp is attacked but manages to hang in. Daedaleus, and Braries, join the battle to help camp. Some campers like Lee Fletcher and Castor, die during this epic battle. Afterwards, Daedalus dies intentionally with Nico's help and the ancient Labyrinth collapses, closing the possibility that Kronos may attack camp through that route again. In the end of the book Percy has a birthday party and Nico showed up and make him a deal to beat Luke

The Last Olympian
In The Last Olympian, Percy leads Artemis' Hunters and the campers into battle to defend New York City. The gods of Olympus are unable to help defend because they are out fighting Typhon. Percy is now almost sixteen, and must fight against Luke, who now hosts the Titan lord Kronos in his body. Percy's fighting is eased a bit by the fact that he bathes in the River Styx, making him indestructable except for his Achilles point, the small of his back. After fighting the raging battles, he, Annabeth, Grover, and Thalia make a stand in Olympus, where the Great Prophecy is fulfilled. Kronos is defeated because Annabeth managed to bring Luke back, causing Luke to take control of his body and stab himself in his Achilles spot, killing himself and Kronos. The Great Prophecy is fulfilled by Luke being the hero, since the cursed blade was the knife he gave Annabeth long ago, because he broke his promise of protecting her and betrayed his friends. Luke ended up being the hero of the prophecy (though Percy was the one who made the great decision to give Luke the knife to stab himself and believe as Annabeth was that Luke was capable of fixing everything). They were down to a very low number of campers at Camp Half-Blood, but the number is growing once again. This is when Percy realizes that he turned sixteen just around the time he decided to give Luke the knife, to make his big decision in the prophecy. The story and series end when Percy concludes that he didn't look back after racing Annabeth to Thalia's Pine Tree, a suitable ending.

Personality
Percy is usually portrayed as being friendly and weird, and 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, and 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.

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 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 the her in. Fleeing the scene, he arrives in the museum to meet Mrs. Dodds, his math teacher. Suddenly, she attacks him and transforms into a Fury, but he manages to evade for a miraculously long time until the arrival of Mr. Brunner, his Latin teacher, who throws a pen at Percy which transforms into the bronze sword Anaklusmos or Riptide. 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 them, 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
Thalia's tree, which serves as the magical border of Camp Half-Blood (which was formed by Zeus to prevent his daughter from dying), has been poisoned mysteriously by unknown forces. After Chiron is dismissed from camp (he is blamed for poisoning the tree), Tantalus takes his job. The only thing able to rid the tree of its poison is the Golden Fleece, which is located on Polyphemus's Island, in the Sea of Monsters (the Bermuda Triangle).

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.

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 40 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
&nbsp

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. Though they are there for only a few minutes, when they return truly almost an hour had passed since they entered. 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." 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 (whom he has fallen in love with and 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. They lead Rachel to New York, who gets a ride from a taxi driver, who leads them straight to camp.

Once they get to camp, they leave Rachel behind because she is mortal. 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) 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, "Percy, you are not the hero.' It will affect what you do."

As the battle wages on, Percy, Annabeth, Grover, and Thalia ascend to Olympus after chasing Kronos. 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 twelve 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.

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, and was able to bear the weight of the sky, the curse of Atlas.
 * 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. Like most other demigods, using his abilities tires him.
 * 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, complete with lightning and wind, as his father is the god of storms.
 * 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 control all parts of boats telekinetically, especially sails.
 * 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 make water appear from nothing, though doing so is particularly taxing.
 * 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. 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 neutralizing most poisons.
 * Percy can create earthquakes and cause volcanic eruptions(As seen in The Battle of the Labyrinth).

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.
 * 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 was blown into. Percy used 1 to call Mrs. O'leary when they where in trouble in the battle of the labyrinth.
 * Magical Pearls, given to him by a nereid. He gave one to Annabeth and Grover leaving his Mom, but in the The Lightning Thief Movie He gives them to his Mom and Annabeth while Grover stays behind
 * A wristwatch which turns into a shield, given to him by Tyson. 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 Fransisco when Percy sacrificed it to save Tyson, Annabeth, Percy, and Grover.
 * Nemean Lion pelt, obtained in The Nemean Lion Skirmish, when he planned the murder 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.

Fatal Flaw
In The Titan's curse, it is said by Athena that Percy's fatal flaw is excessive 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?'. Luckily 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. In the Last Olympian, Rachel kisses Percy in Paul's (his mom's new husband) Prius right before setting off to the Princess Andromeda. 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. Rachel always seems to 'ruin' everything between Annabeth and Percy, which Percy is clueless to.

Annabeth Chase: 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, again as he leaves her to fight the telekhines at Mt. St. Helen's in for luck The Battle of the Labyrinth, 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 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.

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, she tries to hint that she loves him, but Percy, suddenly nervous, changes the subject, leaving Annabeth disappointed.

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

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.

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.

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 dad a lot and his dad grows to love him too.

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 his dad at first nickname Paul "Mr. 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. 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".

Olympians

 * Poseidon: Percy is on good terms with Poseidon primarily because he is Poseidon's son. At the end of The Battle of the Labyrinth, Poseidon states 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.
 * Zeus: Zeus, the king of the Gods, 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 Two to not bear any more children, but is pleased when Percy returns his Master Bolt to him in The Lightning Thief. After Percy returned the bolt Zeus allowed Poseidon to talk to his son. During the winter solstice in The Titan's Curse, Zeus votes to let Percy live, but this may have been tied to the fate of his own daughter, Thalia, as well. However, Thalia had agreed to become one of Artemis' Hunters before this, so it is possible that this may not have mattered. 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, and therefore immortality, for saving Olympus from the Titans.
 * Hades: Hades, the lord of the underworld, has mixed feelings about his nephew Percy. Percy previously accuses him of stealing Zeus' Master Bolt when it was in fact Luke who stole it. Later however, he returns to Hades his Helm of Darkness and clears his name of all charges pressed against him. 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 mentioned by Percy during his decision of rejecting immortality, Hades is shown casually addressing him, with none of the malice that he normally shows throughout the series.
 * Ares: The god of war dislikes Percy. His hatred for his cousin only intensifies when Percy defeats him in a duel in The Lightning Thief. It is dangerous for Percy that they are on bad terms because Ares, being the god of war, 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 which did happen during Percy's fight with Atlas. He only goes along with granting Percy godhood because he can fight him as many times as he wants and Percy will just keep coming back.
 * Athena: The goddess of wisdom, war, strategy, industry, justice and skill disapproves of her cousin's friendship with her daughter Annabeth Chase because of the historical rivalry between herself and Poseidon, but Percy has not done anything against her directly. In The Titan's Curse, she may have helped to guide him at the Hoover Dam. However in the same book, she also voted that he be destroyed. In The Last Olympian, Athena is on good terms with Percy, with the exception of his relationship with Annabeth.
 * Hera: The goddess of women and marriage, neither likes nor dislikes Percy. Near the end of The Battle of the Labyrinth he and Annabeth both disagree with her views of families having to be perfect, siding with Hephaestus on the matter instead, 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 primarily has been on Mr. D's bad side from the very second they met. Percy does not like his cousin Dionysus very much either, for he constantly antagonizes Percy (and all other demigods, for that matter) by never calling them by their real names (preferring to call him "Peter Johnson" or "Perry Johansson"), but 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 latter. However, at the end of the Battle of the Labyrinth, their relationship comes to better terms after one of Dionysus' sons dies in the final battle. 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. They are on much better terms by the end of The Battle of the Labyrinth. Although Dionysus denies this, he favours Percy with his judgement, help, and advice, more than any other god in the series. This may be proof that Dionysus is acknowledging Percy, and that their relationship is improving.
 * Hephaestus: Hephaestus is grateful to his cosuin 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 (who had been imprisoned under it), 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.
 * 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. Their relationship took a turn for the worse after realizing that Percy could not save Luke and Hermes grew bitter to all heroes. 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: Aphrodite 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. Being the god of prophecy, he also told Percy how important dreams could be.
 * Demeter: Demeter and Percy have a poor relationship due to Percy's lack of respect towards her.
 * Hestia: Percy and Hestia have a good relationship. In The Last Olympian, Percy entrusts her with Pandora's Jar that contains the spirit of hope, Elpis, saying that "hope is best kept by the hearth". This helps mend her anger towards the gods for giving her a small role as well as her perception of demigods, which Kronos had used to bring many of the minor gods to his side. She also helps him and shows him the stories of Luke.

Titans

 * Kronos: 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 grandpa. He thought it so strange he dismissed it completely. Nevertheless, Percy is Kronos 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.
 * Lapteus: This is the one of the only Titan Percy is on good terms with. In "The Sword of Hades," 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, who tricked Annabeth to carry it, who then had Artemis take the burden so Atlas could join the war. 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, they probably under better terms.

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 book he stated that "he never advertised the date because it fell right after camp ended."
 * 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 series, the one to slay Medusa.
 * Though Percy had said many times in the series that he had disliked 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.
 * 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), kill Medusa, get the Golden Fleece, battle the Nemean Lion, visit the Garden of the Hesperides, enter the Labyrinth and bear the Curse of Achilles.
 * He was the first person ever to kill the Clazmonian Sow.
