Perseus "Percy" Jackson is the demigod son of Sally Jackson and Poseidon, the half-brother of Tyson, the former stepson of Gabe Ugliano, the stepson of Paul Blofis, the titular protagonist of the Percy Jackson and the Olympians book series by Rick Riordan and the film adaptations, one of the main characters in it's sequel book series The Heroes of Olympus and a supporting character in the second sequel series The Trials of Apollo.
He is the son of the sea god Poseidon and has been diagnosed with dyslexia and ADHD. Percy has been an outcast all his life, but when his satyr friend Grover takes him to Camp Half-Blood, a safe haven for demigods, a whole new world opens for him. He won't let any bully, monster, bad guy, Titan, or obstacle stand in his way, and the series consists of Percy learning what it truly means to be a hero and going through a handful to save Mount Olympus.
In the films, He is portrayed by Logan Lerman, Who also played D'Artagnan (The Three Musketeers 2011 film)
Percy began the story as a mischievous twelve year old going from one boarding school to another. Although he was a demigod, he didn't know anything about the world or that his father was alive and a god until his maths teacher Mrs. Dodds turned into a Fury and tried to attack him, but failed when Percy vaporised her with Riptide. After going to Camp Half-Blood and being revealed as Poseidon's Son, (it is against the rules for the big three gods Zeus, Poseidon and Hades to have kids) he went off on his adventure with Grover Underwood and Annabeth Chase. After the quest he was betrayed by his friend Luke Castellan who revealed that he was in league with Kronos.
Since then he has gone through many adventures and met many friends. Eventually he fought for Mt. Olympus against Kronos in The Last Olympian, and started dating Annabeth. In The Heroes of Olympus set four months after the Titan War, he's taken away from Camp Half-Blood by Hera and loses his memory. He becomes the leader of Camp Jupiter (a camp for Roman Demigods) but soon in The Mark of Athena he meets with his old friends, and he, along with Jason Grace, Piper McLean, Leo Valdez, Frank Zhang, Hazel Levesque and Nico di Angelo, travels in the Argo II for the rest of the journey to stop Gaia rising. At the end of the book, Percy and Annabeth fall into Tartarus, and resum in The House of Hades. The two forced their way through, and closed the Doors of Death. But their battle against Gaia's giants finished in The Blood of Olympus with Percy and Annabeth deciding to finish their senior year of high school together before attending New Rome University.

- Poseidon: Percy's father; He is the Greek God of the Sea. He was unable to be with Percy when he was growing up due to laws saying that Gods must not interacted directly with their demigod children.
- Thalia Grace: Percy's cousin (as Percy's father Poseidon is brothers with Thalia's father Zeus); They have the occasional clash but they do care for each other.
- Nico di Angelo: Percy's cousin (Percy's father Poseidon is brothers with Nico's father Hades); Originally Nico disliked Percy for "letting" Nico's sister Bianca die but later reconciled. In House of Hades by Cupid's urging Nico is revealed to be homosexual and has a crush on Percy though the latter is unaware of this. Though in The Blood of Olympus, Nico reveals this to Percy, but has now moved on and starts a relationship with Apollo's son Will Solace.
Kronos: The main antagonist of the series. Ever since the gods defeated him millenia ago, Kronos, king of the Titans, is determined to destroy the gods and take over the world.
Gabe Ugliano: Percy's cruel stepfather who mistreats him and Sally before his adventures begin.
Mrs. Dodds: Percy's mean math teacher at Yancy Academy who despises him and on one field trip turns into a Fury and attacks him.
Luke Castellan: Son of Hermes and a conniving traitor. Traumas in his childhood fueled him down a dark path, which led him to rebel against the gods and take sides with Kronos. Later, Percy could understand why Luke went rogue.
Polyphemus: A monstrous cyclops who lives on an island in the Sea of Monsters. He uses the stolen Golden Fleece to lure satyrs into his cave to capture and eat them; Percy and his friends outsmart him.
Percy Jackson and the Olympians
The Lightning Thief
Yancy Academy was where Percy's troubles seem to start. He has only one friend at the school, Grover Underwood, whom is also Percy's best friend. During a field trip to a museum, Percy is annoyed by the school bully, Nancy Bobofit, for intimidating Grover and in a fit of rage, accidentally summons water from a nearby fountain to pull her in, but he didn't know how he'd done it. Mrs. Dodds, his pre-algebra teacher, witnesses the whole scene and tells him to follow her into the museum for a "talk." Suddenly, she turns into the Fury Alecto, and attacks him, looking like a bat with humongous fangs. Percy manages to destroy her using Mr. Brunner’s pen, Riptide, that transforms into a sword in his hand. However, when Percy returns to the bus and asks his classmates, nobody remembers Mrs. Dodds because of a force known as the Mist. The only person that may remember her was Grover, who always hesitated before he answered. Everybody else believed her name was Mrs. Kerr.
Percy arrives back at the school and hears Grover and Mr. Brunner talking about his life being in danger and becomes very suspicious. At the bus stop, Grover sees that the three Fates are looking at Percy while knitting giant socks. Soon after, the Fates snip the string of life. Later, he goes home on his own at the end of the school year, even though Grover asked him to wait for him at the bus stop. He arrives home to his horrible step-dad Gabe Ugliano and his friends playing poker. Gabe immediately demands money for his poker game and although Percy denies he has any, Gabe deduces that he has change from the cab drive and forces it from him. Percy's 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 seeing Gabe get hit in the butt by the door when he does a weird hand gesture he saw Grover use . During their night in Montauk, Percy had a vivid dream . The dream features two animals, which is a horse and a bird attacking each other. At the same time, there is a voice(that Percy describe as so deep and evil that it turned his blood to ice)gorging the two animals on. Percy was awoken by the pounding of the door . He and his mother are shocked to see Grover outside their cabin, without pants (which Percy recommends not to see that) coming to him and his mom, telling them to leave. Percy was confused at his friend's appearance, as he was a goat from the waist down and revealed himself to be a satyr. Nevertheless, his mother took them both in Gabe's prized possession, a 1978 Camaro and began driving at daring speeds through a blinding hurricane, and it was blasted off the road by a bolt of lightning. As Grover, Percy, and his mom tried to get out, they saw the Minotaur, a half man, half bull monster, who had been chasing them. The three of them managed to dodge it by following Ms. Jackson's advice to jump out of the way at the last second, but Grover was too slow and the Minotaur injured him, but got distracted by Percy's mother. The Minotaur forgot Grover, grabbed Percy's mom by her neck, and she disappeared in a golden flash of light. Percy, in a surge of new power and anger, managed to defeat the Minotaur by breaking off its horn and stabbing the Minotaur in the chest. Percy dragged the unconscious Grover past a hill, and then passed out when he reached the porch of a house. He was cared for in the infirmary by Annabeth Chase, waking up three days later. He learned that he was at Camp Half-Blood, a place where people were trained to survive against monsters.
Percy learned that the director of the camp was the Greek wine god, Dionysus, who was very unpleasant and moody, and Mr. Brunner, former Latin teacher from Yancy Academy, was actually the hero-training centaur (half human, half stallion), Chiron. Shown around camp by Annabeth, his new friend and head counselor of the Athena Cabin, he found out that all the campers were demigods, also known as half-bloods. He himself was a demigod, but no one knew his divine father. After being shown around the camp, he currently resided in the Hermes cabin, whose head counselor was Luke Castellan. Luke befriended Percy and treated him with respect. Afterwards, Percy encountered Clarisse La Rue, counselor of the Ares' cabin, who performed the "initiation ceremony", which was sticking Percy's head in the girl's bathroom toilet. Her plan backfired when Percy shot water out of the toilet to blast back at Clarisse and her buddies. This officially began their rivalry. Later in a game of Capture the Flag, Percy defeated Clarisse and three others single-handed when he touched the creek, which healed his wounds from the fight and gave him a sudden burst of adrenaline. After Capture the Flag, a hellhound summoned from the Fields of Punishment, came out of the forest and attacked him. Percy's injury from the hellhound heals by touching the water; then suddenly, a holographic trident floated above Percy's head, which told everyone that he was the son of Poseidon, the god of the sea, therefore explaining his powers over water. As the monster was not from the forest, it meant that someone within camp had summoned it, because nothing, including weather, could enter the camp's magic boundaries without permission.
One day, Percy was offered a quest to retrieve Zeus's Master Bolt by Chiron. Chiron explained to Percy that Zeus lost his master bolt, and (since Zeus has a rivalry with Poseidon) blames Percy, as Zeus suspects that Poseidon is attempting to dethrone him. Chiron said that if Zeus doesn't get his bolt back by that summer solstice, he would begin war with Poseidon. Percy accepts the quest and consults the camp's Oracle of Delphi. Soon after learning that Master Bolt has been stolen, Percy embarks a quest with his sword Anaklusmos, better known as Riptide, and Grover and Annabeth. Along the way, they face many monsters—the Furies,Medusa, Echidna, along with her pet Chimera. After Ares offers them a mode of transportation west, they arrive in Los Vegas, where they stumble upon the Lotus Hotel and Casino. They get trapped in the cansino for five days, leaving them only one day to complete their quest. They faced Procrustes before finding their way to the Underworld. The trio face Hades, the lord of the dead, who believes Percy stole his Helm of Darkness and the Master Bolt. Hades saved Percy's mother right before she died from the Minotaur, explaining the golden flash. Torn between saving his mom and finishing the quest, Percy finally uses Poseidon's Pearls to find the missing gods' items. Immediately returning from the Underworld, he finds out that the war god Ares has the Master Bolt and the Helm of Darkness, and challenges the god to a duel for possession of the bolt and the helmet, in which he wins. A dark force, later revealed to be Kronos, stops Ares from killing Percy. Ares vanishes in his divine form, leaving the bolt and Helm of Darkness behind. Percy gives the helm to the Furies to return it to Hades, who in return sends back Sally to her apartment, and the trio goes to New York to return the bolt to Zeus. Percy gives Medusa's head to Sally, who uses it to turn Gabe into a statue.
Percy goes back to Camp Half-Blood, where everyone at the camp congratulates him, Annabeth and Grover included. At the end of the summer, Percy can't decide whether to stay at camp or enroll in seventh grade and live with his mom. He finally decides to go train to clear his mind, where he sees Luke training at swordplay. As they drink Coke together in the forest, Luke reveals he was behind the theft of the bolt and the Helm of Darkness, and vanishes. However, before he left, he summons a pit scorpion to kill Percy. Percy manages to kill it, but it stabs its stinger into Percy's palm. He tried to reach the camp but collapses. However, several forest nymphs carry him and after being fed ambrosia and nectar, Percy heals and decides to enroll in the seventh grade and come back to camp next summer.
The Sea of Monsters
When Percy is attacked by Laistrygonian Giants at school, Annabeth rescues him along with Tyson. On the way to camp, in the Gray Sisters' Taxi, which is a taxi business run by the Fates. Percy learns some coordinates (the coordinates on where to find the Golden Fleece) that lead to something he needs. Percy arrives at camp to find the camp under attack by Colchis Bulls and drives them back with help from Tyson who is fireproof. He later learns Thalia's pine tree is poisoned, meaning the borders are weakened and the activities director Chiron has been blamed. Clarisse, the daughter of Ares and Percy's enemy, is assigned a quest to go to the Sea of Monsters (using the coordinates Percy received) to find and retrieve the Golden Fleece, which has healing powers for plants, animals, and humans which they need to heal Thalia's tree. Percy and Annabeth decide to go also, but Dionysus and Tantalus, the new camp director replacing Chiron, refused.
Meanwhile, Polyphemus, a Cyclopes, captures Grover. Polyphemus believes that Grover is a female Cyclopes and he wants to "marry" Grover, for he is wearing a bridal gown. In desperation, Grover creates an empathy link with Percy so he can call for help. With Hermes' help, Percy, Annabeth and Tyson board the Princess Andromeda, the ship Luke and his forces are on and escape. They fight the Hydra and get on Clarisse's ship, the CSS Birmingham. The CSS Birmingham is a tribute to Ares. As they enter the Sea of Monsters, Clarisse, Tyson, Percy, and Annabeth have to get past Scylla and Charybdis. Scylla lives on a cliff, while Charybdis lives in the middle of the entrance to the Sea of Monsters. Instead of attempting to sail in between the sisters, Clarisse automatically goes for Charybdis and Tyson, a good Cyclops and the half-brother of Percy, supposedly perishes in Clarisse's ship after the ship got blown up due to malfunction problems.
Percy and Annabeth journeyed to many dangerous islands including the Sirens' Island and Circe's Island, and Annabeth tells Percy several stories about Thalia’s death, which she also mentions her prophecy. When they reach Polyphemus's island they join up with Clarisse, Grover, and later Tyson, who miraculously survived thanks to Rainbow, a friendly hippocampi who dragged him out of the water. They leave with the Golden Fleece after fighting Polyphemus, which Polyphemus stole many years ago. When they return to the mortal world, they send off Clarisse on an airplane to the camp alone to drape the Fleece on the tree, and Luke kidnaps Percy, Annabeth, and Tyson, but Percy reveals Chiron's innocence in a secret Iris message sent to camp. Percy challenges Luke to a duel, but - with Percy being inexperienced and out of practice, which made him no match for Luke's polished swordsmanship - Luke effortlessly defeats him and very nearly kills him. However, Chiron comes to rescue them with his strangely dressed relatives. When they return to camp, the fleece is placed on the tree, which not only revives it, but also brings Thalia back to her full life form. This revival was actually Kronos' plan, done so that he would have another chance to manipulate the prophecy that governs the future of Olympus and the Olympians.
The Titan's Curse
Thalia Grace, Percy and Annabeth heard from Grover that two half-blood siblings, Bianca and Nico di Angelo, had been found in a middle school. The three immediately set out to find him. Grover had been awaiting for their appearance. He explained that he found the two half-bloods and that they were enjoying a function in the gym. He was very nervous and embarrassed as the only person he could dance with was Annabeth, who had recently grown taller than him so he looked quite stupid "dancing" with her. Percy, having been forced to dance to blend in with the crowd sees the two half-bloods following Dr. Thorn, which was not a very good sign. Percy felt disgusted by the fact that Thalia was always powerful and a hero at everything she'd done and so thought it was now his time to shine and ran to save the di Angelo's from danger alone, though his plan did not work out as planned.
Then, Artemis and her Hunters appear and Annabeth falls from a cliff as she had climbed on Dr. Thorn with her knife before the Hunters shot him down with their arrows. Being a son of Poseidon, Percy did not feel Annabeth dropping into the water, which confirms the fact that she had been captured. The Hunters saved Percy and his friends from the manticore. After a while, Percy clearly understood that he and Thalia were not under speaking terms due to the fact that Annabeth had fallen down the cliff. Nico had taken a great interest on the fact that he was a demigod and exchanged many thoughts on the Greek gods, Bianca had been dumbfounded and was summoned by Artemis with Percy, where Bianca pledged her life to Artemis much to Percy's protests.
Artemis then sends her Hunters to Camp Half-Blood with Apollo, her twin brother. When he got to camp, Percy had frequent dreams about Annabeth and that she was in distress. He even went to see the Oracle, however she didn't answer his questions and he left the attic in anger.
After a few days, the camp had a Capture the Flag game, where the Hunters were up against the campers. Thalia and Percy agreed to be co-captains of the demigod team while Zoë Nightshade lead the Hunters. During the game, he learned from Grover that Zoë had a bad dream about Artemis being in trouble, while Percy himself had a dream that Annabeth was suffering under the weight of some unseen object. Thalia told Percy to stay on defense to guard the flag, but when he saw that her team was about to be attacked, he ran up the middle and took the flag. On his way back, he saw Zoë running back with his team's flag and was tripped up by an arrow two feet from the line, allowing the Hunters to win.
Thalia then runs up to Percy, asking him what he was thinking as when she got to the flag spot, it was gone. She then shocks him, but claims it was an accident. Percy uses the creek water to splash her and claims that it was also an accident. Thalia and Percy begin to fight, each one summoning stronger attacks until Percy stopped, seeing the Oracle walking towards them. Percy simply watched as the Oracle approached Zoë, who asked about saving Artemis. The Oracle replied with a prophecy, saying:
Five shall go west to the goddess in chains, One shall be lost in the land without rain, The bane of Olympus shows the trail, Campers and Hunters combined prevail, The Titan's curse must one withstand, And one shall perish by a parent's hand'
Chiron then holds a meeting to decide who will go on the quest. Zoë originally wanted to take all Hunters, but she is convinced to allow a few campers as it was in the prophecy. Zoë however doesn't pick Percy because he is a boy, as Zoe thinks it's horrible to be with a boy, instead picking Thalia and Grover, as well as her own Hunters, Bianca di Angelo and Phoebe. Percy was mad that he was not allowed to take part in the quest, since it was his chance to save Annabeth.That night, he is awoken by Blackjack, who tells him a sea creature is in trouble. He swims out and finds the sea cow trapped in a net and frees it slowly because it was scared of his sword, forcing him to free it by hand. On his way back to camp, he sees Nico spying on the Artemis' Cabin and uses Annabeth's cap to follow him. Percy overheard Zoe telling Bianca that Phoebe had been poisoned by centaur blood on a shirt that Connor and Travis Stoll had given her earlier. Revealing himself to Nico, he is forced to promise Nico that he will watch out for his sister after Nico correctly guesses that Percy will follow the group on their quest. Nico leaves and Percy had just enough time to turn invisible before the Hunters leave the cabin, with Zoë almost bumping into Percy on her way out. As they leave, Percy followed them from above on his pegasi, Blackjack. They followed the car that the four traveled in and stops hours later when the group arrives at the Air and Space Museum in Washington, D.C..Percy then spots Dr. Thorn, the manticore, and overhears him saying that Annabeth is alive and that his dreams were true. He follows the manticore when it doesn't follow the group into the museum. He soon finds the General and Luke, and sees the General creating several Spartus that he was going to use to kill and Bianca. However, the Spartus got hold of parts of Percy's sleeve instead of the General's piece of cloth with the Hunters' scent on it, resulting in them hunting him instead. Percy quickly escapes using Annabeth's Yankee cap to find the others. Zoë in particular, was surprised and angry when they realize that he had followed them and they were soon attacked by a Nemean Lion the Spartus close behind. After finding the lion's weakness, Percy helps defeat it by filling the monster's mouth with astronaut food he found in the gift shop. This made the monster expose his mouth long enough for Zoë to finish it off with an arrow.
The lion left behind a Spoil of War, its pelt, which Zoë gave to Percy as he had come up with the plan even though she dealt the finishing arrow. She also allowed him to join the quest after realizing that he is the fifth quest member, despite the fact that the Spartus, now disguised as gray security men thanks to the Mist, are tracking him. They fled Washington and made it to a train line, where they jumped into a rail car with a homeless man who offered them his fire. Though at first oblivious to the identity of the homeless land, a very bad haiku reveals him to be Apollo. He asked Percy to save his sister by looking for Nereus, the Old Man of the Sea, as he could tell them where to find Artemis. Later that night, Percy has a dream where, unbeknownst to him, he is Hercules, and is being handed Anaklusmos by a girl who later realizes is Zoë. Apollo takes them as far west as far as he could, to the last stop in a small town in New Mexico. Despite there being no real way out of the town, they tried to think of ways to leave including renting a cab.
However, the Skeleton Warriors managed to find them again and attacked with handguns while Grover passes out as Pan's presence overcomes him. As they tried to defend themselves against the undead soldiers, who would reform when killed, Grover senses Pan's presence again, along with a gift from the wild - the Erymanthian Boar. However, because it is wild it attacks everyone, not only defeating the skeleton warriors and Thalia and Percy lead it into the woods. They are cornered at a cliff and he tells Thalia to jump at the last second. Thalia however is scared of heights, which Percy quickly figured out and pushed her out of the way causing the boar to crash into the snow.
Grover managed to use his nature magic to make an apple appear in front of the monster's face and the group ride it to a junkyard in Gila Claw, Arizona, owned by Hephaestus. They camp there for the night, but a limo appears and Percy's blood began to boil, which meant Ares was nearby. The god of war came out of the car and told Percy to get inside, as someone wanted to talk to him. Percy reluctantly does so and finds Aphrodite inside. She asks him to hold a mirror as she fixes some microscopic flaw on her face. As Percy watches her, she seemed to change into all the girls he had ever had a crush on. Aphrodite begins to talk about tragic love stories and eventually asked Percy why he was on the quest. He originally told her it was to save Artemis, but with some pushing by the love goddess, he admits that he is really there to save Annabeth. Aphrodite thrills at his response and tells him that she will make his love life very interesting, hinting that Annabeth and Percy will most likely have a romantic future together. She then sends him back to his friends and warns him not to take anything from her husband’s junkyard.
While passing through, Bianca took a Mythomagic game piece of Hades for her brother, Nico. Because of the slight mistake, a defective automaton came to life and started attacking the group. Percy notices a manhole cover at the bottom of the machine's foot and was planning to enter it, however Bianca went in instead, sacrificing herself to kill the monster and save her friends. Percy and everyone else tried saving her, but they knew that it was completely useless as Grover announces tearfully that the next line of the prophecy has been fulfilled.
Thalia takes a truck and drives them to a river, where they rent a few canoes and Percy convinces a few Naiads to steer them to the Hoover Dam. When the Naiads start messing with him and Zoë, she tells him that they have never forgiven her. When they near the dam, Percy, along with Thalia and Grover, begin sprouting facts about the Dam, indicating the depth of their relationship with Annabeth is as the Hoover Dam was one of her personal favorites. They also make dam jokes about the Dam Snack Bar and the Dam Restroom, though Zoë was lost on the humor. As they go to get food, Percy hears the sound of a sea creature he had befriended earlier. He tells it to go away and wonders how it followed him, but is distracted by the sight of remaining Skeleton Warriors - Bianca had managed to kill one in New Mexico.
He runs into an elevator to escape them, but then becomes trapped deep inside the dam. A tour guide, who turns out to be Athena, tells him that there is always a way out for those that are smart enough to find them, before ascending in the elevator. He is spooked when a girl appears behind him and he swings at her with Riptide, but the sword simply passes through her as she is a regular mortal. She then reveals she isn't so regular, as she sees the Skeleton Warriors for what they truly are and directs them away from Percy, who hid in a bathroom. As he thanks her, he introduces himself as Percy and that he has to go (which Rachel thinks means his name is Percy Gotta-go).
Up top, he warns the others of the danger and they are cornered at the top of the dam. He tells Thalia to pray to her father, but she doesn't think he will answer. He says that Athena thinks he will and Thalia asked her father for help. Two statues come to life and swat the undead skeletons away before flying the group to California. There, Zoë Nightshade, who knows a lot about Nereus, tells Percy to look for him by smell as it is different. Percy finds him and hangs on for dear life as the old man tried to shake him off. Percy tricks him into going into the sea, which makes Percy stronger. Nereus changes into many animals to shake Percy off, but his attempts fails and he eventually agreed to answer their question. Percy asked what the terrible monster that Artemis was hunting was, which Nereus says is easy and points to the water before escaping. Percy feels tricked until Bessie, the sea creature that had been following him, appears in the water. Grover understands it and they quickly learn it is the Ophiotaurus, the monster Artemis had been seeking as burning its entrails will give the person who does the power to destroy Olympus.
Just then, Dr. Thorn appears with a small force of mortals and attacked the group, wanting to make his own place in the Titan Army. He tried to convince Thalia to slay and burn the Ophiotaurus so that she could destroy Olympus but Percy manages to shake her out of her stupor. When they were cornered, Percy sends an Iris Message to Camp Half-Blood, but finds only Dionysus on the other line. Mr. D makes Percy ask him politely for help, which Percy does between clenched teeth, and the god saves them by wrapping the manticore and his men in grape vines, saving their lives. Percy then sacrifices the Nemean Lion's pelt to Poseidon to ensure safe passage for Grover and Bessie back to Camp Half-Blood.
Percy then goes to see Annabeth's father, Frederick Chase, as he may have a car they could use to save his daughter. After meeting Annabeth's family, he is shocked that they are so much different from the way Annabeth had described them, as to him they only seem caring and loving. Mr. Chase wants to save his daughter personally, but is told it is too dangerous for him, being just a regular mortal. He reluctantly agrees and gives them his car. Before they leave, Percy makes a promise to Mrs. Chase to tell Annabeth that she still has a home there with them.
As they drive up the mountain towards the Garden of the Hesperides, the car explodes due to a lightning bolt that struck it forcing them to complete the rest of the climb on foot. When they reach the Garden, Percy and Thalia finds out that Zoë is a Hesperide after meeting her sisters, and she is poisoned by the dragon, Ladon. Then they continue on to the place where Atlas held up the sky, though they find Artemis holding that burden instead. Percy finds Annabeth bound and gagged by Luke and the General, who is actually Atlas. Percy challenged Atlas, but his sword becomes too heavy, as Ares curse had finally taken hold (Ares promised that his sword would fail him when he needed it most when Percy won against him before). They were thrown into battle where Luke and Thalia fight each other, while Percy tries his best to hold off Atlas. In the ensuing fight, Percy saw the ruins of Mount Othrys, rival capital of Mount Olympus and home of the Titans, rebuilding itself. He realizes that this meant that the Titans' chances of victory are increasing.
Zoë then intervenes, fighting her father, disappointed with what her father had done. Percy used that moment to ask Artemis to give him the sky as he realized that the prophecy had involved him, and that only Artemis could have a chance against Atlas. He took it while Zoë and Artemis attacked Atlas together, but Zoë is hit and thrown against the wall. Artemis managed to push him back under the sky while Percy rolled out of the way. Sadly, Zoë began to die as Percy ran up to her during her last moments. She tells him that he is nothing like Hercules and she is proud he carries the weapon she made before dying.
Percy rescued Annabeth and they manage to escape the mountain, thanks in part to Frederick Chase shooting the monsters with his plane using Celestial Bronze bullets. He, along with Annabeth and Thalia, then go to Mount Olympus on Blackjack and his friends, Guido and Porkpie. While flying, Percy and Thalia believes that Luke is dead as Thalia had thrown him down a deep chasm, but Annabeth believes otherwise. Percy becomes slightly jealous with the affection Annabeth was showing for Luke, which surprises him because it have never really bothered him before now.
When they arrive in Mount Olympus, the winter solstice meeting had already begun, and they begged Zeus to believe that Kronos was indeed rising. Thalia then chose to be an lieutenant with Artemis to replace Zoë, before giving Percy a hug. When he said she wasn't allowed to do that anymore (as Hunters can't become attached to males), she says she was merely honoring a friend. The gods then voted if they should kill Percy as he is the only known child of the Big Three to reach sixteen for the Great Prophecy in two years. Fortunately many of the gods vote to let him live after Artemis declares that if he is killed, then the gods are no better than the Titans. Poseidon also vouches to let the Ophiotaurus live, although kept in Mount Olympus so it wouldn't be a "bargaining chip" against the other gods. Before Percy leaves Olympus, Poseidon tells Percy in private that he has done well and he is proud of him.
Back at camp, Percy tells Nico that his sister had died and gives him the Mythomagic figurine of Hades that Bianca meant to give to Nico. However, Nico blames Percy for not protecting her and throws the figurine away, telling him he hates Percy. At that moment, four of the Spartus appear, somehow managing to get past the Camp Borders. Nico thinks that they are for him and unintentionally splits the earth to swallow them and send them to the Underworld before fleeing into the forest. Percy, realizing that Nico is a child of Hades after the incident, tries finding him, but to no avail. While discussing Nico's abilities with Annabeth, Grover appears, claiming that he'd heard Pan's voice in his head. The three then promise to keep it a secret as Percy knows that Nico could also be a child of the Great Prophecy, but instead says that he himself will take the responsibility of the prophecy instead.
The Battle of the Labyrinth
Percy Jackson thinks that freshmen orientation won't be fun, so his mother shows him the bright sides ("Tomorrow, you're off to camp! After orientation, you've got your date"). Orientation turns out to be hosted by empousai. When he is accompanied by a mortal acquaintance, Rachel Elizabeth Dare (which Percy thought she lived at Hoover Dam), who he met at Hoover Dam in The Titan's Curse, she 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 empousai and runs into Annabeth along the way. They were supposed to see a movie together, but Annabeth is upset when she sees Rachel with him because she is jealous to see Percy hanging out with her when they were clearly supposed to be at the theaters. Annabeth takes Percy to Camp Half-Blood, a camp just for demigods like them. Percy finds his half-brother Cyclops, Tyson, cleaning their cabin. Quintus, the new swordsman, 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 fall in a dark cavern which they later find out is an entrance to the Labyrinth. 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 is trying to use the Labyrinth to get there, guided by Ariadne's String. As Annabeth goes inside to get her prophecy, Percy waited outside and felt a little worried when Annabeth didn't come back for a long time. When she returns, Annabeth begins to tell everyone what the Oracle had told her, but she doesn't say the last line saying she doesn't remember. This strikes Percy as strange that she would forget something so important and begins to wonder what the last line could be. Annabeth takes Percy, Grover, and Tyson along with her. Together, they enter the maze. They are joined by Hera for a short time. She tells them that Percy knows the way, but Percy doesn't know what she means by that. When they take a wrong turn throughout the maze they run into Nico, son of Hades, at the Triple G. Ranch. Nico is accompanied by King Minos’s ghost, who tries to convince Nico that they are not his friends. Once they get out without Nico, Percy and the others run into a quiz show run by a Sphinx.
After they escape from the Sphinx, they find an exit that takes them to Hephaestus, who has them travel to one of his forges to find out who has been using them and in return, he will help them find Daedalus. Percy gets lost in the inner depths of Mount Saint Helens while battling fierce water demons. Before parting with Annabeth, she kisses him for luck. Percy faces four full grown telekhines. They attempt to burn him with lava, but Percy, being a son of Poseidon, is hard to burn. In desperation, he unleashes an incredible amount of power and blasts out of Mt. Saint Helens, creating an explosion that damages the volcano, stirs Typhon in his sleep, and causes the evacuation of hundreds of thousands of people living around Mt. Saint Helens. He ends up falling into Ogygia, where 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. Calypso lets him use a magic raft that will take him to any place he wants, and the only place he can think of is Camp Half-Blood.
He returns to the shores of the camp and finds the camp strangely empty, except the amphitheater where everyone has gathered. As it turns out, they were getting ready to burn his shroud. Annabeth took the stage to say her final words, stating "He was probably the bravest friend I've ever had. He..." She then suddenly saw him and starts hugging him fiercely until she realizes she was making a big scene in front of all of the other campers. As they talk about plans to navigate the labyrinth, Percy realized he knew the answer after talking with Hephaestus on Ogygia; they need a mortal with clear sight to guide them. Once they are accompanied by Rachel, they run into a wide arena, where Percy battles a dracaenae and the demigod Ethan Nakumura. Sparing Ethan, Percy challenges his giant half-brother, Antaeus, the arena master, that is accompanying Luke so that Luke's army can pass. Percy kills him by luring him off the ground, as his mother is Gaea meaning he is invincible on the ground.
When he finds Annabeth and Rachel again, Rachel leads them straight to Daedalus' workshop, who tells them that he is Daedalus and the name Quintus was only a cover; and he also reveals that they are too late; Luke got there first and took Ariadne's string. He says that Rachel is better and more accurate than the string. Monsters then attack the workshop, dragging in Nico in chains. Percy, Rachel, Annabeth, and Nico escape and leave Daedalus and Mrs. O'Leary 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 Kronos comes to life in Luke's body. Percy barely escapes, thanks to Nico and Rachel (who had hit Kronos in the eye with a blue plastic hairbrush).
While they were going through the Labyrinth, they meet up with Tyson and Grover again. Together, they all find Pan, the god of the wild, who tells them he is dying. As his spirit dies, it goes into the mouths of each of them except Nico, 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 reluctantly, 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 Kampê 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 (Daedalus) 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 fiancée) are celebrating. First, Percy's father Poseidon comes and tells him that he fears Luke/Kronos is only temporarily defeated and when Percy blew up Mt. Saint Helens, Typhon stirred in his sleep. Finally departing with Poseidon, Percy decides to go to his room to plant the garden he had earlier promised Calypso. As he does, Nico 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 and ice cream
The Last Olympian
Percy is driving Paul Blofis's Prius with Rachel Elizabeth Dare, while on a quick vacation to the South Shore. Rachel is flirting her way into a relationship, Percy describes that he "felt like one of Apollo's sacred cows—slow, dumb, and bright red." They are soon interrupted by Charles 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. Percy responds by saying, "Oh gods, don't even think about it." Then Beckendorf tells Percy that its time to initiate their plan to destroy the Princess Andromeda, Luke's demon cruise ship inhabited by Kronos's Army. While they are setting the bombs to blow up the ship, some telekhines attack. Percy distracts them to give Beckendorf time to arm the explosives. He battles Kronos, but Beckendorf is already captured. Because the explosives have no timer and Beckendorf has the detonator in his watch, he sacrifices himself to help Percy escape and carry out the plan and Percy jumps off the side of the ship and he loses consciousness.
In the water, he 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 his kingdom being destroyed. 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 have his soul reaped 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 them 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 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 he 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 tiny 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." Ethan, aiming at Percy's Achilles Spot during a battle to invade New York City, stabs Annabeth in the arm with a poisoned blade. Annabeth had pushed herself in the way, as if she had a feeling that Percy was in danger. Percy is furious and horrified, knocking Ethan unconscious. Kronos threatens Percy to surrender or he will kill Annabeth, but Percy calls Blackjack who takes her to a hotel in a plaza. Annabeth is seriously injured, and Percy tells her where his Achilles spot is and that she saved his life. Annabeth remarks he looks "cute when worried" and that his eyebrows "get all scrunched up." When Kronos makes it to the Hall of the Gods, Percy battles him to stop the destruction of the Olympians' Thrones. Kronos asks Ethan to kill Percy as he knows where his Achilles' spot is, however Percy convinces him that what he is doing is wrong. Ethan then charges Kronos, but Kronos opens up a fissure which causes Ethan to fall to his death. 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 offered the gift of becoming a god, but declines due to his feelings for Annabeth Chase. He remembers how he felt when Annabeth might have become a Hunter of Artemis and notices Annabeth looks about the same way that he did then. Because of this, he declines their offer in favor of a request. He requests that the gods claim their children by the age of thirteen and that Camp Half-Blood construct cabins for Hades and the minor gods so their children have a place at camp. 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, due to which a group of eavesdroppers toss them into the lake, 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 for once.
The Heroes of Olympus
The Lost Hero
Even though Percy does not appear in this book, it is revealed that he and Annabeth are officially dating. For most of the book, his location was unknown with the only clue being that he disappeared around the same time that Jason Grace, a son of Jupiter, first physically appeared. It is eventually revealed that Jason and Percy were exchanged by Hera/Juno to unite the demigods of Greece and Rome against Gaea and the Gigantes and other creatures.
The Son of Neptune
Percy Jackson is being attacked by the Gorgons, Stheno and Euryale,intent on avenging their sister, Medusa's, death. The sisters seemingly could not be killed as they reform every two hours while none of their attacks wound Percy because of the Curse of Achilles. He had been running from them for three days ever since they saw him. He had woken up at the Wolf House, having no idea who he was or how he got there (and wondering why the Gorgons can't kill him), and met Lupa, two months before the encounter with the Gorgons. The only thing he remembers is a dim memory of Annabeth. He believes what Lupa and the Gorgon sisters have told him about himself, that he is Percy Jackson, a demigod, the "son of a barnacle-encrusted god from five thousand years ago," which is Poseidon, whom they only know as Neptune. Percy then knocks out Stheno and uses her tray to slide down a hill.
He meets up with June and she gives him a choice: carry her to the other side of the road, or leave everything and go to the ocean, creating a new and invincible life for himself. Percy chooses to carry June to the camp, even though it means that he will lose the Curse of Achilles. After reaching the borders of the camp, he uses water from a nearby river to create two giant hands that destroy the sisters (as the water breaks their connection to the Earth). The waters of the river seemed to have also washed away his Curse of Achilles, as after the waters receded, Percy felt like he had been in an acid bath and he felt vulnerable. Just then, Percy is met by many demigod children, including Frank Zhang, Hazel Levesque, and Reyna Avila Ramírez-Arellano. June introduces him as a son of Neptune and Reyna seems to know Percy somehow when she hears his name. June then shows her true form as Juno and the campers bow in respect, except for Percy who thinks that because he carried her all this way, he didn't feel that she deserved his respect.
Reyna then orders Hazel to take him inside where she could question him. Percy then meets Octavian in the Temple of Jupiter and then meets Nico di Angelo, who he does not remember, but he does think that he knows him from somewhere. From then on, he is initiated into the Roman camp where he impresses some of the campers with his battle prowess during that nights War Games. At the end of the game, Mars himself appears and selects Frank, his son and Percy for the quest to free Death. Percy vaguely remembers his antagonism towards his Greek counterpart, Ares. He somewhat visualizes that they had a fight in in the past. They embark on their quest using the only vessel in the Roman Navy, a pathetic rowboat named the Pax.
They sail to upper California where they meet Iris and see the Giant’s army. They then move to Portland where they encounter Ella and the wicked king, Phineas who also appears to have knowledge of the past, present, and future although he is blind. Ella was wanted by Phineas as he thought she was a very precious harpy because of her knowledge. His intentions were to tie her up and keep her like that but the three friends find it cruel and make a bet with Phineas. They find the location of Thanatos when Percy gambles with Phineas using poison and healing Gorgon blood. By tricking Phineas, with Gaea's help, Percy is able to take the healing vial, from then on his memories begin to return. They eventually reach Seattle and the Amazon company which is run by Hylla, Reyna's sister and also the former secretary of Circe.
After escaping the Amazon compound with great difficulty, the group fled to Frank's house in Canada where his grandmother lived, who unfortunately “had an appointment with death” as the house burst into flames. She had told Frank that he was a descendant of Neptune and he could turn into anything. This had a great effect on Hazel as she was told by Pluto that she would be freed by her curse (blackouts about her pasts whenever she thought about them and finding cursed jewels wherever she was) by a descendant of Neptune. She had thought it was Percy but now she had no idea who would free her. Hazel had also kissed Percy on the cheek for his moral support. From there, they went to Alaska as more of Percy's memories returned. After arriving on the Hubbard Glacier, Frank was able to free Thanatos by burning a piece of wood which contained Frank's life. When the wood burned out Frank would die but only after Frank played a big role. He had entrusted his life with Hazel. Meanwhile, Percy fought off a legion of Roman undead warriors, using his powers to create a hurricane and a massive tidal wave. While Hazel, Frank, and Arion tried to kill Alcyoneus, Percy jabbed Riptide into the glacier. This caused several fissures to open up and all the undead soldiers and Percy himself went falling off the glacier into the sea below. After Frank and Hazel kill Alcyoneus, they retrieved Percy who had the Roman standard and was waiting on a block of ice for them to return.
They return to San Francisco on Hazel's horse Arion, and by the time they return to Camp Jupiter, Percy had regained all of his memories. They met Tyson, Ella, and Mrs. O'Leary on the coast and arrived to the battle in the nick of time. Percy was able to slay the giant Polybotes with the help of the Roman god of boundaries, Terminus. Terminus originally refused to help until Polybotes crossed the border with weapons (which was against the rules) and broke the statue of Terminus. This caused the god to become so angry that he agreed to help Percy, who used his broken head to destroy Polybotes by smashing his head with the head of the god. The other campers see this and raised Percy onto their shields and proclaimed him a Praetor. Later, he went to his room he had a dream and was visited by Hera and they argued about her stealing his memories and his life. During their talk, Hera warned Percy that Annabeth would be the one to cause the most trouble when he arrives in Rome. Percy enraged attempted to smash her in his dream, but she vanished and Percy`s dream ended. The next morning at the Senate, he explained to the Senate about Gaea, the Greeks and Romans coming together, and how the Greeks were on their way in a warship. Octavian tried to convince the Senate it was a trap, but Percy swore on his life that nothing bad would happen. When Reyna stood by Percy the decision was final they would hold fire. As the Argo II approached, Hazel explained to him the position he put himself in by swearing on his life, but nonchalantly Percy wraps his arm around Frank and Hazel`s necks and tells them to come and meet his other family.
The Mark of Athena
Percy is seen walking with Hazel and Frank as the Argo II arrives at Camp Jupiter. Annabeth comes up with a plan to appease the Roman god of borders Terminus and allow them to enter Camp Jupiter. Camp Jupiter Praetor Reyna, on advice from Percy, allows Annabeth, Piper and Jason to descend from their ship to have a meeting in the camp borders. Discussion over the Prophecy of Seven appears to go well and Reyna is on the verge of agreeing to co-operate. However, Leo, possessed by an eidolon, uses the Argo II's ballistics to fire at Camp Jupiter, causing a fight to break out between the two camps.
Jason, Annabeth, Percy, Hazel, Frank and Piper escape to their ship with the Romans hot on their tail. They begin their journey to the ancient lands, making a few necessary stops and visits to certain gods in the U.S before they can leave. After many obstacles, they get to Rome. In Rome, many more monsters attack, with the worst to come. When the demigods of Camp Jupiter realized that Rome was their destination, they resolved to instead go to war with Camp Half-Blood, and they march toward New York. This, however, isn't their only problem. Annabeth, assigned a mission from her mother Athena to recover the Athena Parthenos, must go her own way and thus Percy becomes extremely worried. Furthermore, he still has to face his own problems, including drowning. After he battled with the twin giants Otis and Ephialtes (succeeding by working together with Jason and Bacchus, the Roman form of Dionysus), Percy goes on to help Annabeth, even though a child of Athena must go alone. However, though he finds her in a workable situation that quickly changes.
Guarding the Athena Parthenos was Arachne, who Annabeth tricked into trapping herself. As Arachne falls into the abyss of Tartarus (she and the Athena Parthenos were over the void of Tartarus), she shot out silk spider webs, one of which wrapped around Annabeth's ankle. Annabeth gets dragged towards to Tartarus, and Percy desperately holds onto her.
When it is clear that it was hopeless for Annabeth to be saved, Percy falls into the hole to Tartarus with Annabeth. The other demigods among the Argo II are grief-stricken and fear the worst for Percy and Annabeth. Their fate is unknown as the moment, though Nico states if anyone can make it out of Tartarus alive, it's Percy. He then says then it's especially likely he will live because Annabeth is at his side.
The House of Hades
Percy and Annabeth have been falling for 9 days into Tartarus. They see the ground and a river rushing up to them, which Percy uses to catch them in their fall. The river was the river Cocytus, the River of Lamentation. It gave the two thoughts of giving up and drowning but Annabeth manages to get them to shore. The air in Tartarus is poisonous, and according to Annabeth, smells and tastes like styrofoam peanuts, which Percy remarks, smells like his stinky ex-stepfather, Gabe Ugliano. To enable them to survive the horrors of Tartarus, Percy and Annabeth drink from the flaming river, the river Phlegethon, which allows monsters to endure the punishments in Tartarus. After drinking from the Phlegethon, Percy and Annabeth feel much better and are able to journey through Tartarus. They come across various reformed monsters and Titans, such as Hyperion, and to their surprise, an old friend of Percy comes to help, the good-turned Titan, Iapetus. Iapetus, known as Bob, help them on their quest and allow them to find and close the Doors of Death. However, along the way, complications start to unfold as Bob starts to remember who he is. As they pass a golden bubble, in it the reformed Hyperion, Percy asks Bob to burst his golden bubble since Bob is the only one with a weapon. They then come across the arai. Percy pleas with Bob for help, but Bob hesitates and allows him and Annabeth to get hurt because he realized that they were the ones who wiped his past memories. Seeing Annabeth in deep despair and blindness, Percy has no choice but to battle the arai, resulting in him getting the curse of slowly dissolving. This stretches back to the previous book, The Son of Neptune, where Percy had a bet with Phineas, resulting in Percy surviving after he prayed to Gaea. Phineas then cursed Percy to die a painful death through dissolving. However, Bob finally decides to help after seeing who his true friends were. Together with Annabeth, he takes Percy to the giant Damasen's hut, to get him healed. With that, Percy is restored to his original health and the trio continue their journey to the Doors of Death. Percy and Annabeth use the Mansion of the Night to reach the Doors of Death. However, they are soon faced with great difficulty as the Death Mist fades and they can be seen by the hordes of monsters present at the Doors of Death. On top of that, the primordial of the pit, Tartarus, also takes on a physical form and begins his attacks on them. Percy intends to battle Tartarus, but is stopped by Annabeth, who feels that Tartarus is way too powerful and is a 'class by himself'. Bob and Damasen both agree with Annabeth. With much reluctance, Percy gets into the elevator with Annabeth and journey back into the mortal world, with a promise he makes to Bob to say 'hello' to the stars for him. Percy and Annabeth meet the other five demigods in Epirus and back on the Argo II, he fulfills his promise to Bob by looking in the starry sky and saying "Bob says hello", before the Argo II continues sailing in the night.
The Blood of Olympus
After the group is informed that they must subdue the goddess Nike in the city of Olympia, Percy Jackson, Frank, Hazel and Leo decide to investigate, as their godly parents do not have any strong rivalry between them. They reach the site where the original statue of Zeus used to be there. Percy and Leo provoke Nike by remarking that Adidas shoes were much better than the Nike shoes. Nike, driven by her Greek/Roman schizophrenia orders a fight between the Greeks and the Romans. The demigods then hatch a plan to kidnap the goddess and start a mock fight. During the fight, Percy tells Leo, much to the latter's shock that he had discovered about his secret visit to Calypso, and promises to help him. The demigods then fight Nike's servants, the Nikai, angering the goddess. She charges at Leo, but Percy quickly causes the water to explode beneath the chariot, smashing it and sending the goddess flying. Leo and Frank tie her up and take her to the ship. Afterwards, the Argo II is caught in a hurricane and Jason and Percy go underwater to find out. There, they discover that the storm is being caused by the goddess, Kymopoleia, a daughter of Poseidon, who worked for Gaea. The giant Polybotes arrives and captures Percy in his net. Jason promises to honor the goddess. Kymopoleia accepts and decapitates Polybotes. After curing Percy, Kymopoleia warns him that he was yet to face his fatal flaw. Later, Percy, Annabeth and Piper sneak through the tunnels to Athens and attack the Giants. He and Annabeth are caught by the Giants. After they cut Annabeth's thigh, the rest of the seven attack. The assault goes well until Percy's nose bleed wakes the earth mother. Just then, the gods storm in and fight the Giants with the demigods. Percy and Poseidon fight Polydectis. After the battle the seven learn that Gaea had risen at Camp Half-Blood. While thinking of a fast way back, Zeus suggests to slap the Argo II back to Long Island which they agree on. The second they arrive at Camp Half-Blood, Percy fights off Octavian's recruits. When the battle is over Percy, Annabeth, Piper, Jason, Frank, Hazel and Nico meet at the Big House to talk about Leo. Frank and Hazel tell the others about Leo's plan. They are angry at first but calm down when the two cry while explaining it. Over the next few days the Greeks and Romans get along and he is present at the camp fire before the Romans head back to Camp Jupiter. Reyna and Frank then tell him that he and Annabeth can attend college and live in New Rome as long as they want. They soon tell Nico, who is happy for them. Nico then tells Percy that he had a crush on him, but is now over him, shocking Percy.
The Trials of Apollo
The Hidden Oracle
Apollo takes Meg McCaffrey to Percy's apartment because he thinks he can help them. When they arrive, he asked Apollo what he was doing here and was shocked to find out that he was not a god anymore. He invited the two in when they said they were being followed by malicious spirits.
Percy tells Apollo that he will take him and Meg to Camp Half-Blood, but he needs to focus on his school work as he promised Annabeth that they would attend New Rome University together and that he would also like to meet his younger half-sister. On the way to camp, the three of them are attacked by three Nosoi. One gets to Percy but he summons water from an underground pipe and washes it off of himself and Apollo before the disease becomes deadly, but becomes congested. He gestures for the fallen god to thank him, which he does. Percy tells the two to go to camp, while he talks to a police officer that has just arrived on the scene, and that he will visit the camp on the weekend.
During Nero's attack on the camp, Percy and Mrs. O'Leary arrive via Shadow Travel, and proceed to attack the huge Colossus, with Percy slicing off spikes from the automaton's crown and throwing them to the ground. He and Chiron distract it, while Apollo takes it down with a plague arrow.
After the battle, Percy and Rachel talk with Apollo about what he is going to do next. After he tells them the prophecy he heard in the Grove of Dodona, Percy interprets that his help will be here momentarily, and Leo Valdez arrives shortly afterwards. While the rest of the camp both greets and hits Leo, Percy is so overjoyed, that he only hugs Leo, after which he proceeds to somewhat awkwardly greet Calypso. Percy heads back home soon afterwards, diving underwater with Mrs. O'Leary.
- Percy's birth date, August 18, wasn't revealed until The Last Olympian.
- Percy's real name, Perseus, is used by many of his enemies and many gods in the Percy Jackson and the Olympians series. In The Heroes of Olympus, he is mostly addressed as Percy, with the exception of The Blood of Olympus, in which he is referred to as Perseus by Polybotes and Kymopoleia.
- Percy never revealed his real name to anyone prior to the events of The Lightning Thief, when he first arrived at Camp Half-Blood.
- His real name comes from the fact that Perseus, a son of Zeus, was one of the only heroes in Greek mythology to have a happy ending (although Percy originally favored Hercules).
- Percy claims to have never gotten a grade higher than a C- in The Lightning Thief. However, in The Ultimate Guide, his report card gives him a B- in science. This may be from after the events of The Lightning Thief, possibly from his time in seventh grade (since he and Tyson successfully completed a science exam the fastest thanks to the latter's clumsiness).
- Percy is horrible at archery, as shown in The Lightning Thief, The Battle of the Labyrinth, and The Demigod Files. However, he has improved, as it is shown in his report card that "he has stopped shooting his own teammates."
- Percy has done many things that previous demigod heroes and mortals have such as:
- Killed a snake as a young child as Hercules did (The Lightning Thief).
- Slayed the Minotaur twice (once in The Lightning Thief, and later in The Last Olympian) and defeated Procrustes as Theseus did.
- Killed Medusa as Perseus did (The Lightning Thief).
- Took the Gray Sisters' eye and threatened them for directions to a location as Jason and Perseus did (The Sea of Monsters).
- Faced the Sirens, Scylla and Charybdis, Circe, and Laistrygonians as Odysseus did (The Sea of Monsters).
- Taunted Polyphemus and escaped his cave as Odysseus did (The Sea of Monsters).
- Got the Golden Fleece as the first Jason did (The Sea of Monsters).
- Battled and defeated the Nemean Lion, fought the Erymanthian boar and the Hydra and entered the Garden of the Hesperides as Hercules did (The Titan's Curse).
- Held the weight of the sky like Hercules did. (The Titan's Curse)
- Spent time with Calypso, like Odysseus did (The Battle of the Labyrinth).
- Entered the labyrinth with the help of a mortal with clear sight like Theseus did (The Battle of the Labyrinth)
- Entered the Underworld alive (multiple times) and returned alive as Hercules, Orpheus, Odysseus, and Houdini did.
- Bore the Curse of Achilles as Achilles did (The Last Olympian).
- Carried Hera/Juno in another form across a river like Jason did (The Son of Neptune).
- Confronted Phineas, like Jason and the Argonauts did (The Son of Neptune).
- Faced Alcyoneus, like Hercules did (The Son of Neptune).
- Fought Ephialtes and Otis, like Hercules and Dionysus did (The Mark of Athena).
- Fought in the Giant War like Hercules and Dionysus did (The Blood of Olympus).
- He has fought a total of five Titans, two of which he defeated (Artemis ultimately defeated Atlas). He also defeated a Giant, a feat which no other hero had accomplished other than Jason Grace who dueled Porphyrion, Hazel Levesque and Frank Zhang who killed Alcyoneus, and Dionysus and Hercules who fought alongside the gods against Typhon and the Giants and won both battles before they were granted immortality.
- On the cover of The Battle of the Labyrinth he is seen opening Kronos's sarcophagus, while in the book he was wearing Annabeth's invisible Yankees cap.
- He is claustrophobic, as shown when he went up the arch. However, this doesn't seem to affect him in the Labyrinth.
- Some of the reasons that Percy Jackson got expelled were "accidentally" aiming a Saratoga battle cannon at his school bus, and hitting the wrong lever on a catwalk that made his class take an "unplanned swim" into the shark pool. Both are mentioned in The Lightning Thief.
- During The Son of Neptune, the only things Percy remembers are Annabeth, the fact that he is a demigod, and that Annabeth had some vague connection with San Francisco as well as her being his girlfriend, her looks, and the way she laughed and kissed him every time he did something stupid.
- Poseidon believes that Percy has risen above every hero, even Hercules.
- Percy is the only child of the Big Three without any known living demigod siblings so far.
- Percy, like Annabeth, at one point dreamed of getting his parents back together.
- Percy is the only one that has been able to keep the River Lethe from erasing his memories, as Percy won't get wet in water because he is a son of Poseidon.
- Percy Jackson is based on Rick Riordan's son, Haley, who has ADHD and Dyslexia.
- Percy appears on the cover and in the story line of almost every novel in both the Percy Jackson and the Olympians series and The Heroes of Olympus series. The only novel on which he does not appear on the cover or story is The Lost Hero.
- Oddly, Percy seems to understand Latin in The Son of Neptune after being at Camp Jupiter for a short time, while Jason cannot seem to understand Ancient Greek during The Lost Hero even though he has been at Camp Half-Blood for longer. The reason for this is probably because Chiron taught Percy Latin back at the beginning of The Lightning Thief.
- Hazel thinks that Percy and Jason Grace are similar in personality, as they both give off the aura of power and authority, but also a sadness that they have seen their destinies and are waiting for the day when they will face a monster that they cannot beat. Other ways that they have in common (besides being best friends) are:
