Percy Jackson

Perseus "Percy" Jackson is the main protagonist from the Percy Jackson and the Olympians franchise.

Percy is a seventeen-year-old Greek demigod, the son of Poseidon and Sally Jackson. He is the head counselor at Poseidon's Cabin and a former Praetor of the Twelfth Legion at Camp Jupiter, as well as belonging to the legion’s Fifth Cohort. He was the temporary host of the Egyptian goddess Nekhbet. Percy is currently in a relationship with Annabeth Chase.

Appearance
Percy is described as a very handsome young man, with disheveled, jet black hair, swept to one side as if he just gotten a walk to the beach and bright sea-green eyes like his father Poseidon and grandmother Rhea. He is described in a review as having a "Mediterranean" complexion. He also has a sarcastic, troublemaker smile. Percy is described as about an inch shorter than Jason Grace. He had a gray streak of hair he obtained in The Titan's Curse from holding the sky but has since lost it, as stated in The Mark of Athena by Annabeth. It is said that Percy gets his handsome looks from his father, Poseidon, a reason why Medusa wanted to preserve a statue of him. At the beginning of the series, Percy was average in athletics but later from his training, becomes very fit, muscular, and lean. He does not seem to know it, or may simply refuse to acknowledge it, but a great number of girls (as well as Nico) find him extremely attractive. Even Hazel Levesque stated that "He had the good looks of a Roman god." He is also complimented by Calypso, who when asked whether she was in love with Percy states, "If you could see your face. Of course, you." Like Leo, Percy was noted to have long, nimble fingers in The Hidden Oracle, with Apollo claiming that Percy's hands were perfect for a musician.

After he slew Polybotes in The Son of Neptune, Percy received a tattoo of a trident and SPQR on the underside of his arm to signify that he is a full member of the Roman Twelfth Legion Fulminata. After Annabeth and Percy's reunion in The Mark of Athena, Annabeth says that Percy grew even more handsome, muscular, taller and that his lips are salty. According to Piper in The Mark of Athena, Percy smells like the sea, looks like a skater and a troublemaker, but she can still see what women would like about him, even if he isn't her type. Piper later states that when Percy pleads, his sea-green eyes seemed to be "like a cute baby seal that needed help," and marvels at how Annabeth had ever won an argument with him.

In The Hidden Oracle, the god Apollo is struck by Percy's close resemblance to his father Poseidon, noting that he had the same handsome features, "which easily shifted from humor to anger."

Personality
Percy is a brave, spirited natural leader, and is willing to risk his life to save friends, family, strangers, and sometimes even enemies. He has a sarcastic and smart sense of humor, a laid-back demeanor, and has earned the respect of all the Olympians, including Artemis (who strictly dislikes men), Dionysus (who hates most heroes because of what happened with Ariadne),Hades (who generally hates demigods), and Zeus (who naturally hates children of Poseidon). He also earned the trust and respect of the Romans of Camp Jupiter (who usually don't trust Greeks). Percy remains true and never goes back on his word. However, he is definitely not perfect. Percy is somewhat short-tempered, and thus has trouble controlling his anger (such as when he sees bullying) and tends to do or blurt out things before thinking, no matter the consequences, causing him to get into a lot of trouble. He also feels responsible for everyone and anything which goes wrong. Percy is also really reckless and rebellious.

Many people tell him he is brave, such as friends, family, strangers, and even gods and goddesses. He also states that he has the same "brooding" look as his father, that always branded him a rebel, and that his mom, Sally Jackson, also has a rebellious streak just like him. Annabeth mentions that he is technically smart but seems to act dumb; and is obtuse, meaning he doesn't always see the obvious even when it is right in front of him, such as people's feelings and what they are trying to say indirectly. Despite this he is perceptive when he wants to (or needs to) be; he could tell that Gaea wanted to keep him alive and gambled his life knowing that he was too valuable to Gaea for him to die at that time. Percy can also be derisively sarcastic and moody, and he dislikes being manipulated or forced to obey. Percy also has small feelings for Annabeth Chase at the beginning of the series and these feelings became romantic over the course of the series, but he finally confirms it in The Last Olympian. Although Percy is a leader at Camp Half-Blood, he is considered a troublemaker in school, with a track record of expulsions, like most demigods. His dyslexia makes learning and reading difficult and his ADHDmakes it hard for him to be attentive or to sit still in class. He has never been one of the "cool" kids in class because he hangs out with supposedly "un-cool" people, such as Tyson or Grover Underwood. Possibly because of his bad history in school, Percy feels a strong level of affection and attachment to Camp Half-Blood.

After getting his memories taken by Hera, and living on the streets and fighting monsters, Percy has developed a "wolf stare" that says "No matter how bad you think you are, I'm worse," which enables him to scare off people like gangsters. He is not afraid of anything in the mortal world anymore, including gangs. He notes that it is probably Lupa's influence on him, as he stayed with her and her pack for weeks. Despite being very confident in his own abilities, Hazel Levesque can sense there is a quiet sadness in Percy like he saw his destiny and knew that one day he would face a monster he couldn't beat (similar to how she feels about Jason Grace). In The House of Hades, Hazel states that Percy was a child of Poseidon's better nature: powerful, but gentle and helpful, a person that would guide ships safely to the shore rather than destroy them.

While in Tartarus in The House of Hades, Percy is starting to show a darker and more dangerous side of himself in his personality. He begins to question himself about his morality, and if he's really a good hero or not. He wonders about the people he had previously treated with apathy: Bob, Calypso, and Nico di Angelo. After his return, Percy tries to make up for his tattered relationship with Nico by thanking him for visiting Iapetus and leading the Seven to the Necromanteion. While battling Akhlys, Percy taps into his rage and controls poison to overwhelm Akhlys—to the point where even Annabeth is terrified of him. In Tartarus, there are many instances where Percy feels hopelessness and fear, although he ultimately overcomes it. He's shown to be more prone to aggression when he vows to destroy Gaea and avenge Bob and Damasen, something which does not seem to disappear towards the end of the book.

After the events of The Blood of Olympus, Percy seems to be less impulsive. He has grown a bit tired of the constant dangers of a demigod and looks forward to living a normal peaceful life as much as possible. The cunning sorcerer, Setne tried to manipulate Percy but it backfired on him and Percy succeeded in capturing him. Percy gives more priority to his family and even turns down Apollo's offer to go on a dangerous quest to help the latter regain his godhood. However, he does small favours to Apollo as it is his principle to aid demigods as much as possible.

General Abilities
Percy as the demigod son of Poseidon is an immensely powerful individual as stated by multiple characters in the series in which he has appeared and is one of the most powerful demigods in the series. The only other demigods whose powers rival his are Jason Grace, Thalia Grace, Nico Di Angelo and Hazel Levesque. He has fought and defeated many monsters probably more than any other demigod in the series as well as other demigods, gods, titans, and giants. He on more than one occasion has contributed to the salvation of Olympus and the world as a whole. Percy has these abilities and traits:
 * ADHD: Percy's supernatural alertness and keen senses that keep him ready for, and alive, in battle. It also lets him analyze his opponents fighting style as well as pick up minor details about an opponent, such as where their muscles tense so he can tell which direction they'll attack from. This is one general trait of demigods.
 * Dyslexia: Percy's brain is "hard-wired" for reading divine Ancient Greek instead of mortal languages. During his time at Camp Jupiter he learned to understand, and possibly speak, Latin to an unknown degree. This, along with ADHD, is a trait common to most demigods.
 * Dreams: Like most demigods, Percy had dreams that showed him events occurring in the past, present, and future. However, due to the unpredictable nature of his father, and the raw power the sea god possesses, Percy's dreams are a lot more potent than those of other demigods. He has managed to even view the dealings of fellow demigods, such as Luke, and even ancient ones such as Hercules; gods, such as Hades; and even conversations of Kronos himself, something Luke proclaimed was impossible. It is also possible that like many Ocean dieties, he possesses some inate prophetic abilites manifesting as dreams.
 * Enhanced Physical Condition: As a demigod Percy is faster, stronger than a normal mortal, as well as being more agile and durable. These physical attributes have allowed him to perform feats normal human can't, as well as survive situations mortals cannot. As he is a son of one of the Big Three, he is thus physically more powerful than most other demigods.
 * Enhanced Strength: Being a demigod son of Poseidon, Percy is shown to be considerably stronger than a regular mortal and being a son of one of the Big Three, his strength surpasses most other Demigods, able to knock out demigods with one hit, rip out the Minotaur's horn, able to deflect giants attacks, topple a seemingly insurmountably strong Polyphemus, strangle a snake when he was a toddler, and forced the tip of Porphyrion's spear into the ground while the giant was running, causing the giant's own momentum to flip himself over and that was when he was still injured. He had even held on a ledge, while supporting Annabeth's and his own weight with just his fingers, without much discomfort.
 * Enhanced Durability: Being a demigod, Percy is shown to be more durable than regular humans as he was thrown to solid rock by a giant and only managed a nosebleed and later still defeat multiple giants, shook off a hard kick in the chest from the Olympian god Ares, speedily recovered from a dodgeball thrown by a Laistrygonian Giant, brushed off from a whack in the chest by a giant, shook off hard hits from the Titan, Atlas, withstood a hard blow from Kronos without the Curse of Achilles and many other feats.
 * Enhanced Agility: Being a demigod, Percy is shown to be more agile than a regular mortal as he was able to leap on the huge Minotaur neck, dodge several slashes from Ares, the climb up to Anteaus head in a matter of seconds, vaulted over Polybotes's knee, somersault over a line of Roman shields, and able to keep his footing on a huge slippery, shaking crocodile, all with impossible agility, with Carter comparing his agility to gymnastics. His greatest feat of agility had to be in the Hidden Oracle, when he leaped from a giant statue head to it's shoulder and slip down the ship's rudder like a fire pole with impossible agility. Even the god, Apollo had to admit he was moderately impressive. He even jumped over a 20 foot wide river, despite having Annabeth on his back in Tartarus. Later, Annabeth saids she has no idea how he did it.
 * Enhanced Reflexes : Being a demigod, Percy reflexes are faster than a regular human. Percy was able to deflect a bullet that can travel 1,700 miles per hour, even when he barely even seen the bullet in the Titans Curse. His reflexes also allow him to cut a volley of arrows in half in The Sea of Monsters.
 * Wit: Percy is quite intelligent in his own right, skillfully capitalizing on his surroundings and his opponent's weaknesses and egoes when he cannot overwhelm them directly. This has been shown numerous times, such as when he tricked Ares into walking into a pressurized tide in The Lightning Thief, when he choked the Nemean Lion on space food so that Zoe and Bianca could shoot the inside of its mouth in The Titan Curse, when he tricked Antaeus into jumping into chain (depriving him of his mother's rejuvenating touch) in The Battle of th Labyrinth, and when he outsmarted Chrysaor, by utilizing his crew's fear of Dionysus to his advantage in The Mark of Athena.In The Lightning Thief While searching for the entrance to the Underworld, they encounter Procrustes. He traps Annabeth and Grover using his signature technique — causing them to lie down on a bed while being stretched by ropes until they are exactly the same height of the bed — until Percy tricks him into lying down on one such bed. Procrustes is killed, and the trio proceed to DOA Recording Studios. In The Titan Curse Following advice from Apollo, Percy Jackson found Nereus on the docks of San Francisco, California, after dressing up in old clothes found by Zoë Nightshade. As Nereus is tired of being sought by demigods for answers to their questions and just wants to be left alone, Percy has to catch him long enough to ask one question. However, Percy tricked Nereus into jumping into the water with him holding on, making Percy stronger and overpowering him. During the fight, Nereus shape-shifted into different types of animals, including a seal, a killer whale, and an eel to shake off Percy's grasp. However, his tossing and shape-shifting didn't work well leaving Nereus confused as to why Percy didn't drown at all, and Percy revealed that he was a son of Poseidon, much to Nereus' dismay. He eventually conceded the struggle and agreed to answer the heroes' question. Percy asked him for the location of the monster that Artemis, goddess of the moon and the hunt, had been tracking. Nereus said that the question was too easy and simply pointed to the Ophiotaurus, the creature that had been following Percy and his friends during the events of their quest. In Percy's confusion, Nereus changes into a goldfish and escapes into the sea.
 * Omniscience (possibly):Given how Nereus knew things that were unknown to even the Oracle of Delphi, as well as his ability to give accurate answers to any questions that his captors could pose, it is possible that he knew everything and anything indefinitely. In The Crown of Ptolemy Percy finally understands that Setne acts by looking into his enemies minds, finding something he can relate to and use it against. Setne tried and failed to get a handle on Percy's motives for turning down immortality in the past and thus couldn't find anything to relate to get past Percy's defenses.In The Sea of Monsters Percy uses the pool to send an Iris message to Dionysus at Camp Half-Blood, tricking Luke into revealing the fact that Chiron was framed for the poisoning, resulting in Chiron being rehired. In The Singer of Apollo Percy lies, claiming they're not worthy of his music and might explode. Apollo buys the excuse and leaves with the celedones for his concert in a flash of light. Apollo being the god of truth in all. Percy was the first to recognize the weirdness of the lotus casino in The Lightning Thief. Percy forced Gaia to choose between him and Phineas the seer in The Son of Neptune.
 * Leadership: Percy is a natural leader as he led Camp Half-Blood to victory numerous times. Carter Kane had even noticed his leadership.
 * Will Power: Percy is shown to have great willpower as he held up the weight of the sky for a long period time and endured the sufferings of Tartarus.
 * Fighting Skills: Percy is a naturally talented and excellent swordsman and his skills continues to grow as time passes, capable of holding his own against and even defeating larger, more experienced, and more powerful opponents, including gods like Ares and Hades and Titans like Hyperion and Kronos (though the latter three were accomplished only after Percy had bathed in Styx even though it should be noticed that Percy also beat Kronos once without the Curse of Achilles and it must be noted Ares had underestimated Percy) as well as monsters. In The Sea of Monsters, even when Percy had only trained for a year at the time, was already regarded by other campers to be better than any other camper in Camp Half-Blood at swordplay in the last hundred years, with many even comparing him to Luke in swordsmanship. At this point, Percy sparred against entire cabins at a time, and rather easily beat the guys from the Apollo Cabin. Despite being out of practice when he fought Luke, Percy was briefly able to fight him off, but was overpowered rather easily. Percy was skilled enough to repeatedly injure the giant cyclops, Polyphemusuntil he was laying on his back, and defeated Ethan Nakamura in swordplay. In The Son of Neptune, even after losing the Curse of Achilles, he is still shown to be able to fend off an entire army of continually resurrecting ghosts by himself while still protecting Frank and the golden eagle of the legion. His Greek training and unpredictable, solo fighting style make him particularly dangerous to the demigods of Camp Jupiter, who are used to fighting as a group, allowing him to easily defeat multiple opponents at once as shown in The Son of Neptune. Percy had enough skill to easily defeat an Amazon. According to Frank, Percy "fought like a demon." When possessed by eidolons, Percy fought Jason Grace on even footing (Piper couldn't believe the speed of their sword fighting which she described as a 'blur', as they exchanged multiple of blows that lasted only a second) and injured him to a point that he was knocked unconscious. However, it should be noted that Jason was distracted by Piper's charmspeak at that particular moment, which allowed the possessed Percy to exploit the opening in Jason's defense. In The Son of Sobek, Carter admitted that Percy was a way better swordsman than he was. Percy had even said that there is not a lot of people who could fight him that well, indicating Percy himself, is a better swordsman than most. Percy has also shown many of times that he could talk while fighting, with little effort.
 * Curse of Achilles (formerly): After bathing in the River Styx, Percy was given supernaturally superior speed and strength as well as invulnerability except for his vital spot opposite of the navel. With the Curse of Achilles, Percy's own combat skills are enhanced to the point where he can single-handedly tear through entire armies as well as gods like Hades and Titans like Hyperion (albeit he had some help in defeating Hyperion). He was even able to hold his own against Kronos for a rather long period of time though the titan was only on a fraction of his full power. He later loses it by touching the Tiber river as it was a Greek blessing and he could not enter Roman territory with the curse.[4][5]
 * Empathy Link: Percy has a psychic connection with Grover called an empathy link. In The Son of Neptune, Don the faun said that Percy had an empathy link with another faun who is Grover.
 * Wolf Stare: During his training with Lupa, Percy mastered the "Wolf Stare" that says "No matter how bad you think you are, I'm worse," which is so intimidating it allows him to scare off gangsters.
 * Eye of Horus Symbol: Percy has an image of the Eye of Horus drawn on his palm, which can allow him to summon Carter Kane wherever he is just by speaking his name, though Percy can use it only once. Percy used this to get Carter and Sadie to Governors Island to help him and Annabeth face off against Setne.

Demigod Abilities
As a son of Poseidon; one of the Big Three, Percy is an extremely powerful demigod. He has divine authority over his father's domains and subjects. Percy is considered to be the most powerful demigod in Camp Half-Blood. Hazel had considered Nico di Angelo the most powerful demigod she knew, until she met Percy, and believed that Percy's power rivaled Nico's and Jason's abilities. Nico later states that, even compared to the rest of the Seven Heroes of Olympus, Percy is the most powerful demigod he has ever met. Both through his father's authority and his own inherent power, Percy's abilities include:
 * Water-Induced Abilities: When in contact with or in the presence of water, Percy gains a disproportionate amount of superhuman clarity, strength, speed, agility, and endurance equaling a god. While in this state, he was strong enough to snap Clarisse's electric spear "like a twig," and managed to contend with the war god Ares. In The Lightning Thief, Percy was able to successively disarm Luke, the most skilled swordman at Camp Half Blood for the last three hundred years in the Camp Half-Blood swordsmanship class with a complex maneuver after he'd doused himself in water. In addition, after Percy was pushed into the creek during Capture the Flag, he effortlessly defeated four children of Ares in rapid succession, including Clarisse, with ease. In The Sea of Monsters, Percy managed to shear off a portion of Luke's shield once enhanced by water, demonstrating godlike strength. However, this only lasts for a limited amount of time unless he is completely submerged in water. He also heals himself from any wound and most poisons when he comes into contact with water, the amount of water and time needed for the healing being proportionate to the severity of the wound.
 * Hydrokinesis: With the power of the sea within him, Percy can control every form and great volumes of water, being even able to summon and heal his wounds and cure himself of most poisons with it. Percy can control water to a very high degree, letting him control 10,000 gallons of water in The Demigod Files, but not near omnipotently as previously stated here. He can control it in order to make it explode, or use it to grab something. Percy can summon waves that can easily sink ships. His hydrokinesis abilities include:
 * General Hydrokinesis: He can create water from petrified seashells, as well as being able to create water with his own energy and summoning the "force of the ocean" to his will, as long as he concentrates hard enough. He can also harden water into an almost solid shape.
 * Hydrogenesis: Percy can create water from his own power, though it takes much of his energy for him to do so. Percy did this while at Mount Saint Helens, creating water out of nothing to cause a volcanic eruption, which was powerful enough to cause half a million people to evacuate, and caused ash to fall as far as Lake Tahoe and Vancouver. He also uses this skill while creating his own personal hurricanes. While traveling on the Argo II during The Mark of Athena, he presumably used this ability while combining his powers with Jason Grace's to create powerful storms.
 * Vitakinesis (limited): Since he is the son of Poseidon he can heal most wounds and cure most poisons when in contact with water.
 * Water Propulsion: He can control the water around him to propel himself through water. Percy can shoot water, not only from being in water, but he can blast the own water he creates.
 * Underwater breathing: Percy can breathe underwater and diffuse the oxygen in the water to create oxygen bubbles that allow his non-hydrokinetic friends to breathe underwater. However, in The Last Olympian he was unable to breathe in the River Styx.
 * Water Immunity: Percy can fall from great heights into water, and is unaffected by any amount of water pressure. He does not get wet if submerged in water, unless he wants to. Percy can dry items underwater (as long as he holds onto it), such as a lighter.
 * Water Solidification: Percy can harden water into an almost solid shape. He can use this power to walk on water, by increasing the surface tension of the water to the point where it is solid enough for him to stand on, and water constructs. So far, he has demonstrated creating a strong water shield, and on two instances in The Son of Neptune, he hardened the water into giant hands that followed and imitated the movements of his own hands.
 * Watercraft Manipulation: Percy possesses an intimate awareness of any ship he is on (sailing ships, canoes, motorboats, possibly submarines); being able to telekinetically operate one (as well as anything related to the ocean)
 * Perfect Bearings: Percy has perfect bearings on the ocean, so he can easily navigate his way at sea.
 * Communication: Percy has divine authority over and can talk (normally and telepathically) to equines and sea creatures who mainly treat him with deference and lordly respect. He can also speak to other children of Poseidon underwater (seen in The Sea of Monsters, in a conversation with Tyson).
 * Atmokinesis (limited): Percy can summon hurricanes and other types of storms, but the extent to which he can control them is as of yet unknown. Percy's hurricanes have been shown to be powerful enough to douse the fires on Hyperion's body, leaving the powerful Titan vulnerable to attack. By the events of The Son of Neptune he is able to sustain the storm with less effort than his first use of the skill against the Titan Hyperion, although it still drains him over time. He was also able to use it to knock a giant crocodile off it's footing.
 * Electrokinesis (limited): Percy used this skill unintentionally on one occasion, while creating his own miniature hurricane to fight Hyperion. Sparks of lightning appeared as his hurricane increased in power. His control of this ability, however, is far less than that of a child of Zeus and appears to be a limited side effect of his storms.
 * Aerokinesis (limited): Percy can summon strong winds, which he could use to create storms such as hurricanes and typhoons.
 * Geokinesis: Percy can generate earthquakes and (consequently) cause volcanic eruptions, but his control of this technique is less than that of a child of Hades.
 * Cryokinesis (limited): Percy can use cryokinesis to a small degree. He is able to use the ice and snow around him to make an icy hurricane, as he does during the battle in Alaska in The Son of Neptune. He can also manipulate frozen or icy water around him, demonstrated during his interrupted fight with Thaliain The Titan's Curse.
 * Toxikinesis (limited): Percy can control and manipulate poisons, as seen when he beats Akhlys in Tartarus in The House of Hades, as well as deflecting Polybotes' poison that was thrown at him in The Son of Neptune. This is limited, though, as poison is only part water. The full extent of this power is unknown although he is able to control it well enough, when angry, to the point of terrifying Annabeth who even asks him to stop. In The Blood of Olympus Percy tried to divert the poison Polybotes attacked him with, but did not due to his fear of this power.
 * Heat Resistance: As a son of Poseidon, Percy has a far higher than normal resistance to heat and burns, similar to that of a Cyclops, due to his father's oceanic nature. In The Lightning Thief, he manages not to drop his sword when Alecto wrapped her fiery whip around his wrist. In The Battle of the Labyrinth, he was able to survive being engulfed by lava thrown by the telekhines, though it began to get more painful the longer he was in contact with it, as well not being killed by the super-heated steam from the eruption of Mount Saint Helens.
 * Mist Control (limited): It was revealed in Percy Jackson and the Singer of Apollo that Percy can control the Mist, as shown when he made a police officer look at an imaginary line of limos to distract him. Though Percy can indeed control the Mist, he is not an expert at it and his power over the Mist is inferior compared to those of Hazel Levesque and children of Hecate. It is implied in the Lightning Thief that he may have a capacity for magic, with him using an evil ward to send Gabe Flying before even realizing his demigod heritage.
 * Zoolingualism (limited to Equestrians and Marine Life):Percy can understand and talk to marine animals, horses and similar creatures.

Eye of Nekhbet Abilities
In The Crown of Ptolemy Percy temporarily hosted the goddess Nekhbet and gained several abilities while doing so. He lost those abilities when Nekhbet left him, but the abilities he displayed while hosting the goddess included:
 * Enhanced Strength: The kopis Percy was wielding felt heavy in his hand except while he was hosting Nekhbet.
 * Surveillance Magic: Percy was able to see into the Duat with Nekhbet's "super vulture senses". This allowed him to see magical auras and allowed him to see what Setne was doing to the Duat. However while Carter was wearing Annabeth's Yankees Cap Percy couldn't detect him.
 * Vulture Avatar: Percy could summon a giant glowing purple vulture around himself. He used the avatar to fly and to hold onto Setne while flying. The avatar was also able to protect Percy from Setne's attacks.

Magical Items

 * The Minotaur's Horn, he obtained this when he killed the Minotaur after it supposedly killed his mother, Sally Jackson.


 * Anaklusmos (Riptide in English), made of celestial bronze, given to him by Chiron to fight monsters. When uncapped, it becomes a 3 foot tall double-edged celestial bronze sword and causes the fear of most monsters around it. Riptide is usually kept as a ballpoint pen when not in use, and it will always return to Percy's pocket. It used to be the weapon of Hercules, who got it from Zoë Nightshade. In Last Olympian, Riptide can deflect blasts from Hades. When combined with his hydrokinetic powers and Curse of Achilles, Riptide becomes an "arc of pure destruction."


 * The 12th Legion's Eagle, Percy seized the Eagle from the undead army of the frozen Roman Camp on the Hubbard Glacier during The Son of Neptune. He later used it during the battle at Camp Jupiter, where he used its lightning to destroy hundreds of monsters before passing it to Dakota.


 * Medusa's Head, Percy received it at the end of the first book. He cut it off and sent it to Olympus, but Poseidon sent it back. Percy, having no need for it left it with his mom, Sally Jackson. His mom uses the head to petrify her abusive husband Gabe and then sells the resulting "statue" as an art piece named The Poker Player.


 * Stygian Ice Whistle, a special dog whistle made of Stygian ice that was cooled in the River Styx. It was given to him by Quintus (Daedalus) to summon Mrs. O'Leary and shattered after it is blown once. Percy used it when his friends were having trouble fighting an army of monsters in The Battle of the Labyrinth.


 * Wristwatch shield, a wristwatch which turns into a shield, given to him by Tyson. It was badly dented by Dr. Thorn in The Titan's Curse. Tyson came back and fixed it at the beginning of The Battle of the Labyrinth. It was lost later in Battle of the Labyrinth when thrown at Kampê. It was inscribed with the images of the events of The Sea of Monsters, including Percy fighting the bronze bulls, Annabeth killing the Laistrygonian, Tyson riding Rainbow the hippocampus, and Tyson battling the Hydra whilst holding a box of doughnuts.


 * Nemean lion's pelt, obtained in The Nemean Lion Skirmish, when he planned the death of the Nemean Lion. He sacrificed it to Poseidon in The Titan's Curse.


 * Sand dollar, given to him for his 15th birthday by his father. He splits it in half and gave one half to the Hudson River and the other half to the East River gods to stop Kronos' forces on boats in The Last Olympian.


 * Chameleon Armor, he used this in a game of Capture the Flag in the short story of "The Bronze Dragon". It only works from a distance.


 * Hermes' multivitamins, these multivitamins make the person who ate it to be immune to nearly any attack, which was used by Annabeth during the Sea of Monsters to turn Percy back into a human after Circe turned him into a guinea pig and prevent Circe from using magic against her.


 * The Golden Fleece, used after Annabeth was wounded by Polyphemus, he used the Golden Fleece to heal her. Then it was used to save Thalia's tree at Camp Half-Blood.


 * Pandora's pithos, this was given to Percy by Prometheus to open it and give up hope. Later he gave it to Hestia to look after it, because "hope survives best at the hearth."


 * Thermos of winds, this was used by Percy and Annabeth in the Sea of monsters to escape Princess Andromeda and Charybdis. Given to him by Hermes.


 * Magical Pearls, these pearls can transport a person to the sea when smashed. Given to Percy by a Nereid.


 * Moonlace, a flower that grows in the moonlight (given to him by Calypso). He planted it at a trough at his apartment, to remember Calypso.


 * Javelins, these aren't normal javelins, because they have a grappling hook and an explosive setting. Used in chariot races at Camp Half-Blood. Used first in The Sea of Monsters.


 * Daedalus' Wings, stolen in a skirmish in the center of the Labyrinth. Now in a trash can after being thrown away, too damaged for further use.


 * Winged shoes, given to Percy by Luke Castellan. In the book, the wings spring out when the wearer says "Maia". Percy gave them to Grover. It was supposed to be a trap from Luke, as the shoes almost dragged Grover into the pits of Tartarus, due to Kronos dragging them in. In the film, he used these to retrieve a pearl.


 * Travel Rose, which he used in The Sword of Hades to return to the world of the living after having returned Hades’s sword.


 * Kopis, which was created when Percy took Carter Kane's wand and Percy wielded in battle against Setnein The Crown of Ptolemy. Destroyed during the battle.

Trivia

 * 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 on 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).
 * Slew 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).
 * Successfully won a fight with Ares as Diomedes 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 a 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 storyline of almost every novel in both the Percy Jackson and the Olympians series and The Heroes of Olympus series. The only novel in which he does not appear on the cover or in the 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 like 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:
 * They have both been praetor at some point by being raised on a shield.
 * They have/ had a girlfriend whose the daughter of a goddess (Annabeth Chase, Piper McLean).
 * Aside from each other, they had a best friend who performs more comic relief than they do (Grover Underwood, Leo Valdez)
 * At some point in the quest, each had girls that did not trust them (Piper McLean wasn't sure of Percy at first and didn't catch her eye as a hero, and Hazel Levesque and Annabeth Chase disliked Jason as he seemed too perfect).
 * They were kidnapped and switched by Hera in The Lost Hero for the purpose of forging bonds between the camps.
 * Both of their godly parents (Jupiter and Poseidon) didn't appear at all in the Heroes of Olympus series until The Blood of Olympus.
 * Both were under charmspeak by a sorceress (Circe, Medea) which backfired.
 * They were both compared to a superhero (Aquaman and Superman respectively).
 * He's distantly related to his friend Frank Zhang due to his ancestor Periclymenus, something Percy tells him he is proud of.
 * Hera told Percy that the Heroes of Olympus must come together, but Percy was the only demigod to be said to be a Hero of Olympus by the Olympians themselves in The Heroes of Olympus.
 * In The Demigod Files, we see that Percy's worst fear is the camp in flames with his friends dead, or it could be interpreted as losing those close to him.
 * Percy is Poseidon's favorite son.
 * Polybotes thinks if he harms Percy, Poseidon will become weakened due to his love of his favorite son.
 * Percy is the only known bearer of the Curse of Achilles not to be killed by their weak spot and the only one known to lose it.
 * The River Styx is the only river Percy cannot control or breathe in.
 * Percy has two pets, Mrs. O'Leary and Blackjack. As a result, he held the record of having the most pets out of every single demigod except for (as revealed in The Son of Neptune) and later tied with (as of The House of Hades) Reyna.
 * Percy Jackson is one of only five characters whose birthday was revealed in the books. The other four are Thalia Grace, Hazel Levesque, Jason Grace and Annabeth Chase.

 * Percy's favorite brand of chewing gum is Trident.[6]
 * Percy's favourite colour is blue. This was in rebellion to Gabe Ugliano's statement about blue food not existing. Also, this link's to the blue of the sea, Poseidon's realm.
 * Percy told Thalia Grace in The Titan's Curse that he likes listening to alternative rock and bands such as The White Stripes. He says that it's one of the "only CDs he owned that his mom liked."
 * As of The House of Hades, Percy, Annabeth, and Nico are the only demigods known to have gone to Tartarus and survive the experience.
 * In The Battle of the Labyrinth, when Percy first arrived on Ogygia, he said, "Holy Poseidon." In The House of Hades, when Leo Valdez first arrived on Ogygia, he said, "Holy Hephaestus." Poseidon and Hephaestus are their respective godly parents.
 * It was mentioned in The Son of Neptune that it was unheard of for a probatio like Frank Zhang to be promoted directly to centurion rank. Percy was still probatio when he was made praetor, the highest rank at Camp Jupiter.
 * He is also the first and only known Greek to hold a position of leadership within Roman ranks.
 * Percy is thus far the only known demigod to be involved with two major prophecies in both series: he is the "half-blood of the eldest gods" mentioned in the Great Prophecy and one of the seven half-bloods in the Prophecy of Seven
 * Percy is called "Peter Johnson" several times by Dionysus throughout the Percy Jackson and the Olympians series. He has also been called are Perry Johansson, Pierre, Pedro, and Jorgenson by Dionysus in The Battle of the Labyrinth and The Last Olympian.

 * While acting as a narrator, Percy heavily censors explicit content.
 * It was revealed in Percy Jackson's Greek Gods, that Percy's favorite type of music is rock 'n' roll.
 * Percy is the only male hero of the Seven whose mother is still alive.
 * Percy was one of the only two demigods in Camp Half-Blood (the other being Thalia) who was considered to be capable of equaling Luke. Although unlike Thalia, Percy was fairly easily beaten by Luke in their only duel to the death whereas Thalia not only fought Luke equally but even beaten him in their only duel to the death.
 * Also unlike Thalia, who believes herself to be superior to Luke, which was proven in their fight on the Titan's Curse, Percy was uneasy of the prospect of fighting Luke.
