Percy Jackson

Perseus "Percy" Jackson is the main character of the series. He is a demigod, son of the god Poseidon, making him a very important and powerful demigod. He is currently the only known demigod child of Poseidon. His mortal parent is Sally Jackson.

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

History
Percy Jackson was raised by his mother, Sally Jackson as 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 Fury (proper name is Alecto as shown in The Last Olympian), after he first discovered his powers with water in the local pool, but didn't realize it, and she attacked him. Mr. Brunner, Percy's favorite teacher (taught Latin and Greek Mythology) but actually a Centaur, Chiron, in disguise, 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 all year.

Percy goes home to his mother during summer break after being expelled, and she informs him that they will be spending the weekend in a cabin at Montauk beach. As they are sleeping, Grover appears at the door, saying that "they are after him" and they drive away as fast as they can in the middle of a hurricane. After lightning blasts the car off the road, they start to scale Half-Blood Hill to get to Camp Half-Blood, where Percy will be safe, and suddenly a Minotaur attacks them, making Sally disappear in a flash of golden light.

Percy is discovered to be the son of Poseidon during a game of Capture The Flag, and he is blamed by Zeus of stealing his master lightning bolt, and if Percy doesn't get it back by the summer solstice there will be a war that "will make World War II look like child's play." He does this with Annabeth Chase and Grover Underwood. After they discover the thief was Ares, Percy challenges and manages to beat the God of War by stabbing him in the ankle with Riptide. He also managed to bring his mom back, as she never died, She was being kept in the Underworld by Hades the whole time because Hades was convinced that Percy stole his Helm of Darkness, which was actually taken by Luke Castellan.

In The Sea of Monsters, he goes back to camp in which he discovers Grover is missing. Clarisse is assigned to do this quest but Percy, Annabeth, and Percy's new half brother, Tyson, snuck out of camp to rescue Grover.

In The Titan's Curse, Percy, Annabeth, and Thalia go to a military school (Westover Hall), where Grover 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 and Annabeth.

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.

In The Last Olympian, Percy leads Artemis' Hunters and the campers into battle to defend New York City (or more specifically, the Empire State Building). He 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 small 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 and all is well at Camp Half-Blood once again. They were down to a very low number of campers at Camp Half-Blood, but the number is growing once again thanks to the fact that Percy made the gods promise to claim all their demigod children by the age of thirteen.

Personality
Percy is usually portrayed as being good-natured, friendly, and often willing to risk his life to save his friends, strangers, and even his enemies. Athena tells Percy that that is his fatal flaw as of The Titan's Curse. 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 often sarcastic, but not 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 former 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, Percy rushes upstairs to his room, which is used as Gabe's "study" while Percy is gone for the school year. But Gabe is still about to taunt and make fun of Percy, as usual.

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, a bolt of lighting takes the dying Minotaur to the Underworld. Grover takes Percy to Camp Half-Blood and he is introduced to the other campers, who Percy learns are all demigods.

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. Percy himself is a demigod, but no one knows who his divine parent is. He learns that Mr. Brunner is actually a centaur and is the camp's director. He also learns that the warden of the camp is the god Dionysus, who is very unpleasent and moody. 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 learns that he is the son of Poseidon. After the capture the flag game Percy hears a mysterious howling and a hellhound comes out of the forest and attacks them. 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.

After they return, Luke tries to kill Percy, saying that he is an agent of Kronos, and that he will soon overtake Olympus. Percy is saved with the timely help of friends, and is determined to find Luke and stop him.

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 (who came from the Fields of Punishment and can not have food or water) 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 revives Thalia too. 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 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 Luke 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 shoved him off the edge with her shield, Aegis. During the battle, Zoë receives deadly injuries; she is poisoned by a Drakkon, 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. Also, after winning a chariot race with Annabeth, Annabeth kisses him on the cheek. 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. 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, son of Hermes, 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 monster-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, a tiny island undiscovered by mortals. 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 must battle demigod Ethan Nakumura. Sparing Ethan, Percy challenges his giant half-brother, Antaeus, that is accompanying Luke. Percy kills him by having him off of the ground, for the earth helps him heal.

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 fading. As his spirit fades, 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 then readying for the Titan army's arrival. Battling side by side are Annabeth and Percy. Percy, remembering what Zelda had done earlier in the maze, gets to her side and they both fight a fierce monster of the Titan's army. 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, Daealus comes and tells them that the Labyrinth is tied to his life.

The child of Athena (Deadalus/Quintus) 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, 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 set to return to camp in the fifth book, during which a war similar to that of the Olympians and Titans ages ago is beginning; he is expected to challenge Kronos.

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, don't you dare." 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 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 est. Rachel arrives, revealing that she has had a vision which read, Perseus, you are not the hero." At the end of the book, Luke is the hero.

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 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 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.

Magical Items
Anaklusmos:First given to Hercules by Zoe Nightshade named after the surprising current. It was passed on to Percy by Chiron. This is his main weapon. Its name means "Riptide" in English, which is what Percy calls it. It is made of Celestial bronze and can be kept in the form of a ballpoint pen. It's original form was Zoe's hair clip. It always, if Percy loses it, magically appears in Percy's pocket. It is shown in the film The Lightning Thief it has the ability to deflect lightning from Zeus' master bolt

Percy's shield: This shield was made for Percy by Tyson throughout the events of The Sea of Monsters. It was kept in the form of a wristwatch. It was broken in The Titan's Curse. It was fixed by Tyson in between the events of The Titan's Curse and The Battle of the Labyrinth. Percy threw it at Kampe during The Battle of the Labyrinth and it was never seen again.

Hide Of The Nemean Lion: In The Titan's curse Percy defeats the Nemean Lion and it's hide shrivels to the size of a normal lion, Percy wears it and the mist disguises it as a sweater. He later sacrifices the hide to Poseidon to get Bessie and Grover safely away.

The Minotaur's horn: In The Lightning Thief Percy defeats the Minotuar and it turns to dust to reform but leaves a horn behind, Percy takes this with him to camp half-blood and puts in on the wall in his cabin.

Sand dollar: In The Battle of the Labyrinth Posideon gives Percy a sand dollar for his birthday. Percy "spends" the sand dollar in The Last Olympian.

Fatal Flaw
In The Titan's curse, it is said by Athena that Percy's fatal flaw is personal loyalty. Athena was obviously not pleased that her own daughter was an example of this. This means that he will put his friends first before anything.

Romance
Calypso: After Percy is stranded on Ogygia Island, he is healed by the girl named Calypso. She is stranded on the island after supporting her father, Atlas, in the titan-God 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 Bekondorf 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. This does not seem to disappoint Percy very much because he is dating Annabeth by then. 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 Sea of Monsters, though that was only on the cheek, again as she leaves him to fight the telekhines at Mt. St. Helen's in 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, calling him "seaweed brain".

After the 2 weeks of extra camp, Percy and Annabeth are seen together running down the hill from Camp Halfblood. 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 mom 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.

Gabe Ugliano
Percy hates his 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".

Half Brothers
Percy isn't too fond of most of his half brothers. He tricks his half-brother Polyphemus to retrieve the Golden Fleece, and kills his half-brother Antaeus in his underground arena. His other half brother Triton shows no respect for Percy. The only half-brother he is shown to like is Tyson, a child Cyclopes who considers Percy to be his closest brother and friend.

Film

 * 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 visa-versa, and considered her as a friend.
