Luke Castellan

""Ethan. Me. All the unclaimed. Don't let it...Don't let it happen again.""

- Luke

Luke Castellan is a deceased demigod and a son of Hermes. His mortal parent is his mother, May Castellan. He is the main antagonist of the Percy Jackson series. He was possessed by the Titan, Kronos. Although he is considered as the main mortal series' antagonist, he died at age twenty three as a hero of the Great Prophecy. He is portrayed by Jake Abel in The Lightning Thief (film).

Early Life
Luke is a son of Hermes (the god of thieves) and May Castellan, a female mortal who can see through The Mist. He was born in 1986. In 1995 when he was nine, Luke ran away from his mother's home in Westport Connecticut. It was because of her unstable mental problems, brought about by the curse of Hades, which was placed upon the Oracle, who she had tried to become. This caused her eyes to fail her like her family had failed her. This was the moment that Luke later envisioned to tie him to his human life when he bathed in the River Styx.

When he was fourteen Luke found Thalia Grace and Annabeth Chase, and they fought for survival and avoided monsters together. When Thalia got injured by a monster and Luke and Annabeth wanted to rest, Luke took them to his mother's house to heal their wounds. There, Luke met Hermes, his father, for the first and only time. Luke was angry with his father, and demanded to know why Hermes had never showed up when Luke prayed to him. Hermes inadvertently revealed that he knew Luke's fate, and when Luke eagerly asked about it, Hermes refused to tell him. Luke then tells his father that he couldn't possibly love him if he wouldn't tell him, and left with Thalia and Annabeth angrily.

According to Thalia, Luke began to act like he had something to prove after that moment. They got into more skirmishes because of his recklessness, and then they ran into the Hunters. They asked Thalia to join, and she refused, saying she couldn't leave Luke. Zoë, Artemis's lieutenant, hauntingly told her that Luke would let her down, and that caused Thalia to resent and dislike the Hunters.

Eventually the group ran into Grover. Together, the quartet began to travel to Camp Half-Blood but were chased by monsters sent by Hades. Upon reaching the Camp Half-Blood border, Thalia chose to sacrifice herself so that Luke, Grover, and Annabeth could get into camp without being killed by the monsters that were hot on their trail. As Thalia was dying, Zeus took pity on her and turned her into a pine tree. From that point on, Luke lived at camp all year round, all the while slowly falling into darkness.

Allegiance to Kronos
When he was about seventeen, Luke was offered a quest by his father Hermes: to seek a Golden Apple at the Garden of Hesperides. He was honored by this offer, but eventually began to question it, as it was done before by Hercules. He went on this journey, but failed and was scarred by the dragon guarding the tree, Ladon. He returned to the camp and according to his words, was treated with "pity" by the campers. It was then that he began to hold a grudge against Olympus and his father, Hermes, who he felt didn't love him. He wanted to tear Olympus down, stone by stone at that point. Luke apparently was able to injure Ladon and steal a claw; he has since kept the Ladon's claw in the Big House attic. He bided his time and began to have dreams of Kronos.

He was later contacted in his sleep by Kronos, lord of the Titans. The nature of this encounter is unknown, but he was convinced to join Kronos's cause out of a desire for revenge. He was assigned to steal the Master Bolt, Zeus' primary weapon, and the Helm of Darkness, Hades' godly weapon, in order to start a war between the gods.

On a camp field trip to Mount Olympus, he made his move. While the other campers and counselors were asleep he entered the throne room and was able to steal the Master bolt and the Helm of Darkness because, in their arrogance, the Olympians were caught off guard. They later discovered the theft and went to search for the thief. Ares found Luke and fought him. According to Luke, he would have won, but underestimated his opponent and was outmatched. However, he managed to save himself by speaking in Kronos's words that if the Master Bolt was successfully stolen, there would be a full-scale war. Ares was awed by this, and spared Luke, but took the Bolt and the Helm with him. Luke then managed to make it safely back to Mount Olympus before anyone noticed his absence, but Kronos began to punish Luke with nightmares and he swore never to fail again.

The Lightning Thief
Although Luke succeeded in his mission, his failure to defeat Ares cost him dearly. Kronos punished him with nightmares, and Luke swore never to fail the malevolent Titan again. This would also cause him to fear Kronos greatly for many of his later years.

When Luke was about nineteen, he was told in a dream from Kronos that another camper would be coming to Camp Half-Blood, one who would unwittingly take the stolen weapons of the gods down to Tartarus, therefore ensuring that there would be a war. Luke remembers this and finds this camper in the form of a twelve-year old boy named Percy. Knowing that Percy was the boy that Kronos was talking about, Luke befriends the boy and is successful in earning his trust. He welcomes him into the Hermes cabin (where children who haven't been claimed go), trains him in sword combat, and provides the moral support that Percy needed as a newcomer.

One night after a Capture the Flag game, he summons a hellhound to attack Percy in an attempt to make Chiron, the camp activities director, believe that the camp isn't safe for Percy. Unaware of Luke's treachery, Chiron sends Percy, along with Annabeth and Grover, to find the Master Bolt in order to prevent a war. Because monsters of Hades were unusually active and because it was as yet unknown that the Helm of Darkness was also stolen, it was believed that Hades was the Lightning thief and the group set out to go to the Underworld. Before Percy goes on his quest, Luke gives him a pair of winged shoes as a gift. These shoes were actually cursed to drag him, along with the Master Bolt, down into Tartarus when he neared it during his journey into the Underworld. However, this failed when Percy gave the shoes to Grover because Percy shouldn't fly, because Zeus is the Lord of the Skies and does not like Percy. Grover managed to escape from the burden when the time came. After Percy discovers that the Master Bolt was in a backpack that Ares had given him and he had won the Helm of Darkness in a duel with Ares (who was unknowingly being influenced by Kronos), Percy returns alive to Camp Half-Blood along with his two companions after returning the Bolt to Zues, thwarting Kronos' plan.

In order to prevent Percy from interfering again, Luke takes Percy in the woods to 'look for something to fight.' While talking with Luke, Percy begins to slowly see Luke's dark side; Luke's words are bitter and he mentions his sword, Backbiter, which is able to kill both monsters and mortals. Luke then summons a pit scorpion to poison Percy. Luke tells Percy of his bitterness and desire for revenge, as well as his allegiance to Kronos, saying that there will be a new "Golden Age" that Percy won't be a part of, before teleporting away. The assassination attempt on Percy fails when the scorpion is killed and the wood nymphs bring him back to camp for healing.

Luke's betrayal was a surprise to many campers and counselors, especially to Annabeth, who reacted with great sadness at the loss of another childhood friend. Annabeth, however, admitted that Luke had been acting oddly ever since his failed quest and eventually admitted to herself that her dear friend was indeed a traitor and said "May the gods curse him".

The Sea of Monsters
A year after his defection, Luke took control of a monster cruise ship called the Princess Andromeda, which serves as his base of operations. In order to render Camp Half-Blood defenseless and eliminate a major ally of the Olympians, he poisons Thalia's tree with the help of a spy in the camp's ranks. The plan was to later 'allow' Percy and Annabeth to take the Golden Fleece and heal Thalia's tree, so Thalia would be purged from it. He also frames Chiron for the poisoning, causing him to be fired from the camp and be replaced by Tantalus.

At first, Clarisse was sent to find the Golden Fleece and save Grover from the cyclops Polyphemus but was interjected by Percy Jackson, along with a group of allies consisting of Annabeth Chase and Percy's half-brother Tyson.

Hermes, Luke's father, persuaded Percy, Annabeth, and Tyson to go on this quest, and told them to go onto the Princess Andromeda, hoping that Percy would meet up with Luke and convince him to stop his assault on the gods. Percy and his allies landed aboard the Princess Andromeda, not knowing of its true nature, and were captured.

During this time, Luke told the two of his plans to use the Golden Fleece to complete Kronos' resurrection and attempts to recruit Percy and Annabeth to his cause (not willing to recruit Tyson as he reminds him of the cyclops that captured him and Thalia years ago). The two refuse, prompting Luke to order his bodyguards to feed the trio to a Drakon. Percy and the gang escape through a lifeboat propelled by the thermos containing the four winds given to him by Hermes.

Luke later intercepts Percy and his friends when they are looking for a boat that they can use to get back to camp. When he is interrogating Percy for the Fleece infront of a pool (his army of monsters watching), Percy uses the pool to send an Iris message, tricking Luke into revealing the fact that Chiron was framed for the poisoning, resulting in Chiron being rehired (using the fact that he was in a panic due to Percy giving the Fleece to Clarisse). Enraged, he ordered Percy and his friends to be killed. Percy convinces Luke to duel him, a moment both had been waiting for a long time. Luke easily defeats Percy even when the latter's power is augmented by the water, but is prevented from killing the latter when he's knocked into the pool by a boxing glove glued to an arrow. The arrow was shot by Chiron and his family of centaurs who had just arrived and proceeded to save them. When Percy escapes, Luke's spite and hatred for the son of Poseidon only increases.

Thalia is resurrected at last. It is possible and very likely that Luke's allegiance to Kronos was affected after this. He obviously wanted Thalia to be resurrected, shown when he says to Percy that he was going to give him the Fleece after he was done using it to resurrect Kronos.

The Titan's Curse
After Thalia 's resurrection, Kronos' second in command, Atlas, devised a plan to capture the Ophiotaurus, which would grant the power to destroy Olympus to whomever killed it and burned it's entrails. He remembers the Prophecy and chooses Thalia to be its killer.

Luke is assigned to aid Atlas with this. However, Thalia and Luke were childhood friends, bringing Luke hesitation to carry this mission out. Knowing this, Kronos tells Luke that if he doesn't succeed in this mission, he would be chosen to be Kronos' host and therefore suffer a fate worse then death. This continues to become true in The Battle of the Labyrinth.

Luke carries the sky in a plan to trick Annabeth into holding it after she was captured, which succeeds. He and Atlas later use this to their advantage by forcing a captive Artemis to hold the sky in her place, and Luke is happy that Annabeth survives. Atlas orders the death of Annabeth, but Luke convinces Atlas to keep Annabeth alive until the Winter Solstice.

Luke is later seen with Atlas when he summons Skeleton Warriors to hunt down Percy Jackson. His final appearance in The Titan's Curse is when Percy Jackson, Thalia and Zoë, arrive at the regrowing fortress of the Titans, where Artemis and Annabeth are being held captive. Refusing to have to kill Thalia, Luke attempts to sway her into joining their side. Thalia refuses and the two engage in a duel. Their ferocity and power demonstrated is incredible, but Thalia ultimately wins the duel, disarming and injuring Luke and cornering him against the edge of a cliff (she claims that she was always able to beat Luke in a duel). Luke continues to goad Thalia ("Is that what you want? To go back to your dad in triumph?"), but Annabeth begs her to spare him. As Thalia and Annabeth argue over his fate, Luke attempts to use the opportunity to try and disarm Thalia of her spear, but she instinctively kicks him off the cliff, something that causes her both guilt and grief.

Although his body is seen by both an approaching army of monsters and Percy, it is later revealed that Luke survived the fall. It is unknown how he survived the fall, although it may have been by Kronos's magic.

After her battle with Luke, Thalia pledges herself to Artemis (though she had previously scorned the offer), in order to stop the prophecy from coming true through her, as she was only a few hours away from becoming sixteen.

Poseidon later notes that the only way a non-Titan/God may take Atlas's burden is through their own free will and if they are a hero with great strength, a true heart, and great courage. Percy points out that Luke was able to take on the Titan's curse and then tricked Annabeth into taking the sky and then used Annabeth to lure Artemis into taking the sky from Annabeth and Poseidon says that Luke is an isteresting case before being distracted.

The Battle of the Labyrinth
Not long after the battle atop Mount Tamalpais, Luke approaches Annabeth under a flag of truce. He begs her to run away with him, as the thought of becoming Kronos' vessel apparently becomes too much for him. Annabeth is suspicious, however, and refuses, despite her determination to save Luke. Annabeth later regrets her decision, something that becomes very clear when Hermes confronts her and blames her for Luke's fate. Luke himself is also hurt by the experience, as implied by Kronos when he states that Luke learned not to trust his friends the hard way.

After the meeting with Annabeth, Luke continues to serve Kronos and prepare to become his vessel. His demeanor becomes marginally softer as he occasionally displays a moral compass that was previously unseen. This is most obvious when Luke becomes furious with Kelli for killing a boy in Seattle and when he indicates that he disapproves of Kampê's release, as she is too chaotic. He makes an attempt to talk with Annabeth again at Antaeus' arena, but this fails when she and her companions escape.

He is also seen in many of Percy's dreams.

When Luke is last seen, he is possessed by Kronos and attacks Percy Jackson, only stopped by the combined efforts of Rachel and Nico. He is not present at the Battle of the Labyrinth.

The Last Olympian
For the largest part of the war, Luke is completely controlled by Kronos, with a few moments of wavering in the Titan's control. In this time, Percy learns that when Kronos achieves full power inside of Luke's body, he will burn through Luke's body and attain his true immortal form, which would mean the end of all life near him (except for the immortals).

Kronos made his way to the throne room of the gods with Ethan Nakamura, destroying the city of Mount Olympus as he did so. Meanwhile Percy, Annabeth, Grover, and Thalia follow closely after. A statue of Hera falls and would have killed Percy and Annabeth if Thalia had not pushed them out of the way. Thalia's legs are trapped under the statue and the others continue on. Kronos battles them in the throne room when they arrive, but Annabeth is able to catch Luke's attention, reawakening him, but only partially.

Ethan betrays Kronos and attacks him, unsuccessfully of course, as his sword shattered against Luke's invulnerable body. Several shards lashed back at Ethan and impaled him, and he staggered to the ground. Kronos, now having another internal struggle with Luke, opens a fissure in the floor beneath Ethan, and he tumbled to his death. Kronos continued to battle the trio, getting closer to his ultimate transformation to his original self.

Annabeth managed to coax Luke back to his own mind. Luke let Percy knock Backbiter into the hearth, leaving Luke defenseless. A beaten Annabeth gives Percy her knife, as they both realized that Luke was the true hero of the prophecy. Percy gave the knife to Luke who stabbed himself in his Achilles heel, which is located under his left arm, close to the underarm.

Percy, Annabeth, and Grover look away, hearing an explosion and Kronos' fading screams. Luke is left lying on the floor, dying. Annabeth says that he would go to Elysium and Luke replies "Think … rebirth. Try for three times. Isles of the Blest". Annabeth replies that he "always pushed himself too hard". Then, Luke asks Annabeth if she loved him. Annabeth replies that she loved him like a brother. Luke then pleads to Percy to not let this happen again. With that, Luke dies just before the gods arrived after defeating Typhon. In the end he is taken away by the Fates, blessed by Hermes, and remembered and honored as a hero by not only Percy, Annabeth and Grover, but by all. Percy realizes that the string he saw the Fates cut in The Lightning Thief, was not his, but Luke's.

The Lost Hero
Luke is seen in pictures belonging to Thalia. When Jason asks Annabeth, who looks pained, who he is, she says "That's Luke. He's dead now." signaling Annabeth has still not gotten over his death yet. Jason then wonders if Percy Jackson wasn't the only boy Annabeth had ever liked.

Weapons
Luke carries the half Celestial bronze and half tempered steel sword called Backbiter. Unlike Percy's sword Riptide which can't hurt mortals, (as they aren't "important enough to kill") Backbiter can hurt immortals like gods, monsters, and mortals. It's made from Celestial bronze and mortal steel. The two metals that the sword is made from are opposites, having magic fused with mortal metal. Percy could sense that the two metals were trying to escape each other during the forging, and that someone (most likely the forger) died in the creation of the sword. In The Battle of the Labyrinth, Backbiter is reforged into its original form--the Scythe of Kronos. Backbiter is named so as it will "bite back" at the gods who imprisoned Kronos in Tartarus. Kronos has the ability to turn his scythe back into Backbiter, as he does in the final battle at Mount Olympus. Backbiter, in The Ultimate Guide, is said to have been used to kill Ouranos. He also carried a bronze knife which he gave to Annabeth.

Personality
Luke showed his darker side as a villian for most of the series, so his character was mostly described as 'evil', however he was a hero in the end, so his character was probably confused but good. In this way, he is more 'heroic' in the old sense of the terms, such as the stories of Theseus, Jason or Hercules. Apparently Kronos chose Luke to host him because he had a strong spirit.

Romance
Annabeth - Before Luke died, he asked Annabeth if she loved him, but Annabeth said that for her, he was like a brother. Though since The Lightning Thief, Annabeth showed great concern, loyalty, and admiration to Luke.

Thalia - It is hinted that Luke and Thalia may be involved in a romantic relationship before Thalia had sacrificed herself at Half-Blood Hill, but all of that dissolved and fell apart when Luke poisoned Thalia's tree in The Sea of Monsters.

Family
Luke's relation with both his parents were a bit rough, implying that he was not close to them. And then he ran away because he didn't like being with his mother. And he also hates Hermes for abandoning him.



Physical Description
Luke is described as a tall, handsome with short-cropped sandy blonde hair, blue eyes, athletic-looking, muscular and has a sneaky look like all Hermes demigod children, but good-looking features. Many girls are attracted to him, even an Empousa named Kelli. The only thing not attractive on Luke is a thick, deep pale scar that runs from the bottom of his eye down to his chin. It is said that the scar was created when Luke stole a golden apple and was then clawed by the guardian dragon of the tree.

Although he is generally very attractive, his appearance has varied over the books. In the first two books, The Lightning Thief and The Sea of Monsters he looks as always did in Camp Half-Blood, but come The Titan's Curse, he begins to look sickly and aged. His usually tanned skin becomes ghostly pale, and his hair is also white (supposedly with gray streaks), especially under the moonlight. He also begins to wear Greek clothing, such as the chiton and the toga (used as an over-the-shoulder cape). However, in The Battle of the Labyrinth, Luke's healthy appearance returns as he gets closer to being taken over by Kronos.This is possibly because he bathed in the River Styx. He wore a white chiton, which made him look timeless. Percy thought he looked too healthy, because his skin had a unnatural glow to it.

Powers
It is not mentioned what supernatural powers Luke has, but this much can be gleaned from what he is known for.
 * As Hermes is the god of travelers and the messenger of the gods, his children might be able to transport themselves in a way similar to the children of Hades. This has been shown when Luke transports at the end of The Lightning Thief.
 * As Hermes is the God of Thieves, he has the ability to steal things without other people noticing, like the Master Bolt or the Helm of Darkness.
 * Luke is said to be a great fighter and swordsman ("The best in 300 years!", according to Chiron, except maybe for Percy).
 * He has a strong spirit, because even after Kronos chooses him as his host, he can still make his own choices in the end.
 * Luke himself has shown supernatural powers twice. The first time was at the end of The Lightning Thief; he slashed Backbiter through the air and disappeared, apparently teleporting away. However, it is unknown if this was due to his own power, or a power given to him by the sword. The second time was during The Titan's Curse when he summons a pool of water and fire. Once again, it is unclear if this was an innate power.
 * Once Kronos possesed him, Luke had the Titan Lord's abilities to control time around him and other people (chronokinesis), such as making time slow down.
 * So that Kronos can have a host, Luke also has the curse of Achilles, making him nearly invunerable (except in a piece of skin under his left arm, and he can also be electrocuted, drowned, ect.).
 * Luke has the ability to turn Kronos' scythe back into Backbiter, which Percy makes him do in a sword fight.
 * He may have a small sphere of control over items of luxury, like in the Sea of Monsters, when he waved over three chairs and they scooted themselves out of the table. Though this may have been a matter of magic, as the Titan army had a knack for enchanting items to bend to their will.

The Lightning Thief (film)
In the film adaptation of The Lightning Thief, Luke is portrayed by Jake Abel.

There have been some changes to his character, one of the most notable being that Luke claims he has never met his father, despite the fact that in the book series their only meeting has a profound effect on their relationship and the way Luke views the Olympians. The relationship between Annabeth and Luke, which plays a key role in The Titan's Curse and especially in The Last Olympian, is not as close as their book counterparts, seeming to be only acquaintances rather than old friends; Luke's backstory is also cut. Luke's scar was inflicted by Percy rather than Ladon, the dragon in the Hesperides garden. Finally, there was no mention of Luke's association with Kronos, heavily implying that Luke acted alone. It remains unclear if there has been any contact between the two at all.

Luke's cabin was also filled with modern-world paraphernalia and he is seen playing Call of Duty: Modern Warfare 2, using a L86 LSW (with red dot) on the map Favela online. He apparently supplies his fellow campers with modern technology.

Luke's role remains mostly the same throughout the movie, however Luke and Percy's final confrontation has changed. Upon discovering that Luke is the Lightning Thief in the Underworld, they confront each other atop the Empire State Building. The two battle, with Luke gaining his scar and the Master Bolt changing hands several times until Luke seemingly has Percy defeated. When he questions whether or not Percy truly is the son of Poseidon, Percy uses the contents of several water towers and knocks Luke off the building and into the nearby ocean, leaving his fate unknown.

Video Game
In the video game, Luke is one of the main characters until the player has defeated Hades. His attacks are mostly poison-based. The others being Isaac and Grover, he is one of the three characters that can grant Haste to a party member. He is resistant to Poison. He is the final boss in the game. This fight is one on one between Percy and Luke.

Graphic Novel
In the Percy Jackson Comic Adaptaion, Luke plays a same role as he does in the book series. He still provides Percy with the flying shoes that almost drag Grover into Tartarus, and was the one who brought Annabeth and Thalia to the camp with Grover. The major difference is at the end of the comic, Luke had already left the camp out of anger (for his failed plans) by the time Percy, Annabeth, and Grover returned to Camp Half-Blood. Also, the scar on Luke's face is on the opposite side in the comic.

Trivia

 * In the graphic novel, the scar on Luke's face is on the opposite side.
 * He happens to be Hermes' favorite son.
 * According to May, his mother, peanut butter & jelly sandwiches and chocolate chip cookies are Luke's favorite snack.
 * Luke happened to be fond of "Kool Aid" (when he was younger).
 * His surname "Castellan" means a governer or warden of a castle.
