Thalia Grace

"I'm honoring a friend. I must join the hunt, Percy. I haven't known peace since...since Half-Blood Hill. I finally feel like I have a home. But you're a hero. You will be the one of the prophecy."

- Thalia Grace

Thalia Grace is a confident Greek half-blood daughter of Zeus. Her mother was a famous TV actress with the surname Grace, but because Thalia was never close to and disliked her mother (she doesn't like to use her mother's surname) because of she thought her brother was lost or died. Her brother (revealed in The Lost Hero) is Jason Grace. She was a friend of Annabeth and Luke on their journey to Camp Half-Blood years ago before Percy Jackson. She was turned into a pine tree by her father, out of pity, Zeus upon their arrival at camp in which she sacrifced herself to save the lives of Annabeth, Luke, and Grover. She was then later revived by the Golden Fleece in The Sea of Monsters when it "worked its magic too well", as Chiron had put it. In The Titan's Curse, she later joined the Hunters of Artemis to prevent herself from being the hero of the Great Prophecy, for she was one day away from turning sixteen.

History
Thalia is a daughter of Zeus. Her mother was a beautiful actress but she was also an alcoholic. After Thalia's birth, Zeus left and Ms. Grace became unstable. About four years later, Zeus returned in his Roman aspect, Jupiter. Thalia noted that Zeus in his Jupiter form was more fatherly towards her and spoke Latin often. Within the year, Jason, a Roman demigod, was born. Zeus had to keep coming to Ms. Grace's house to please her, but left because Thalia's mother kept pushing him to grant her eternal beauty or to visit Olympus. When Thalia was nine and Jason was two, their mother took them for a picnic, but when Thalia went to the car for the picnic basket, Hera/Juno took Jason away to Lupa, a she-wolf (and the Roman counterpart activities director of Chiron) at the Roman Camp Half-Blood. Thalia was heartbroken by her brother's "death" and called his disappearance "the last straw" with his mother and ran away from home.

After running away, Thalia came across another demigod, Luke Castellan son of Hermes. They became friends and joined forces to fight monsters that attacked them. It is assumed by some fans that they started a romantic relationship. When Thalia was twelve, she and Luke found eventually ran into Annabeth Chase, a plucky blonde-haired seven year old. Luke admired her courage, and gave her his knife, and promised that he wouldn't fail her like her family had. The three of them stayed in different warehouses for protection and shelter, but when their nearest one was destroyed, Luke was forced to return home for supplies. The three of them met May Castellan, Luke's mother, and Hermes, Luke's father. As May bandages Thalia's injured leg, Luke and Hermes got into an argument, causing Luke to storm out of the house with Annabeth and Thalia not too far behind.

Soon they were found by a satyr named Grover Underwood who tried to get them to Camp Half-Blood. Together, the quartet traveled to Camp Half-Blood but were chased by monsters from the Underworld because Hades discovered Thalia's existence and was angered that Zeus had broken his oath not to sire anymore children. They would have escaped, except for the fact that a Cyclops stopped them so that monsters could catch up. The cyclops held Thalia, Luke, and Grover in the air to direct the monsters in their direction, but Annabeth saved them by stabbing the Cyclops in the foot.

They also met the Hunters of Artemis and Zoë Nightshade almost convinced Thalia to join the hunt, but Thalia refused to leave Luke. She and Zoë argued and Zoë told her that Luke would disappoint her. Once they reached camp, several monsters attacked, and Thalia sacrificed her life on Half-Blood Hill to protect Annabeth, Luke and Grover. Zeus took pity on his daughter and to prevent her soul from going to Hades, Zeus turned Thalia into a pine tree.

Thalia hated to be called "Grace" saying, "That's my mother's surname. I don't use it." when it was brought up. Her mother died in a car accident two years before Thalia's resurrection. Thalia might have been named after the ancient Greek muse Thalia of comedy and idyllic poetry.

When Thaila was sent to the Underworld to find Hades' sword in the short story, The Sword of Hades from The Demigod Files, she saw Melinoe, the goddess of ghosts, as her mother.

The Lightning Thief
In The Lightning Thief, Thalia is mentioned once in one of Percy's dreams. Curiously, she was said to have stormy green eyes instead of electric blue.

The Sea of Monsters
In ''The Sea of Monsters Thalia's tree is poisoned and the magical borders around camp are failing. Clarisse is sent on a mission to find the Golden Fleece and revive the tree, but Percy and Annabeth don't want to risk Clarisse failing, and also go on a separate quest.''

Percy asks Annabeth about Thalia, and whether she would have agreed with Luke. Annabeth was exasperated by the question, and asked Percy if he would ever betray Olympus, of which the answer was no. Annabeth said that Thalia got angry with her father a lot, but her personality and heart resembled Percy, and she would never have betrayed her family.

Thalia later appeared in Percy's dreams with stormy blue eyes this time and it is shown she might be the one to bring back Kronos to life.

She comes back to life to conclude the second book after Clarisse places the Golden Fleece on her tree, which is good and bad because it means that Thalia can also be the one of the prophecy and Kronos would take advantage of that. Annabeth, Grover and Chiron are stunned at Thalia's return. Curiously, again, they say she has electric blue eyes, counterparting Riordans first mention of Thalia, when he said she had stormy green eyes.

The Titan's Curse
Grover is sent on a mission to find more half-bloods, and he sends a distress call from a military school, Westover Hall where he has found two. Thalia, Percy, and Annabeth go to Westover Hall, at the time of the school dance. Thalia manipulated the Mist to trick a resident teacher, but it doesn't convince the vice principal, Dr. Thorn, who is a Manticore. Thorn takes the two demigods Bianca and Nico di Angelo, and Percy goes after them, ignoring Thalia's orders to wait. Thorn is about to take the demigods away when Grover, Thalia and Annabeth arrive, but he is thwarted by Artemis and her hunters. Annabeth tries to protect her friends but ends up disappearing with the Manticore. Thalia is upset the hunters have arrived, especially their lieutenant Zoë Nightshade.

Thalia is disgusted when Bianca joins the hunt. Artemis sends the campers and hunters with her brother Apollo to go to Camp Half-Blood. Thalia is frightened when Apollo allows her to drive his sun chariot and terrifies Percy and Grover with her driving. They land in camp where Apollo slyly warns Thalia to be good, knowing something she didn't.

The groups is greeted by Chiron and Mr. D. Percy and Dionysus get into an argument, but when Nico distracted Mr. D, Thalia took Percy away and warned him not to get on another god's bad side. Percy is still distressed by Annabeth's disappearance, and Thalia agrees that they should not give up hope on her.

Zoë asks for the quest, and Chiron gives it to her. They decide to take two Campers, and three Hunters. Thalia quickly volunteers. In the end the group is: Zoë, Thalia, Phoebe, Bianca, and Grover. Percy is shocked and upset that he can't go.

However, the Stoll brothers give Phoebe a poisoned T-shirt that covers her in painful hives as revenge for Phoebe's actions against them in Capture the Flag. Even though they only have four questors, Zoë insists they leave, because she does not want anyone else to be in danger, but Percy follows them, determined to rescue Annabeth.

The Hunters, Thalia, and Grover stop at a museum after many hours and from a distance Percy (who followed them) sees the General,Dr Thorn and Luke but gets caught.Percy quickly escapes using Annabeth's cap and notifies Thalia and the others.

Though the group (Zoë and Thalia in particular) was rather surprised and angry (especially Zoe) to realize he had followed them, they are interrupted when the Nemean lion attacks. Nothing is able to pierce its armor, much to the anger of the group. However, Percy discovers a weakness and has an idea to expose it. He finds astronaut food in a gift shop and throws them into the Nemean lion's mouth. It causes the creature to expose his mouth long enough for Zoë to finish him off with an arrow.

Percy soon encounters Apollo again when they get on a train headed west. Apollo advises him to seek out Nereus, the Old Man of the Sea.

Thalia and Percy both sit together, and Percy discovers that Artemis had offered to make her a Hunter, and that is why she didn't like them (the Hunters). Thalia is quiet at first, and then tells him that she didn't join them because of Luke, and then says that Annabeth had been thinking about joining them, and that he should figure out why. With help from Apollo, they reach a small town in New Mexico. There they are surrounded by the skeletal warriors. Grover then senses Pan's presence and a wild gift from him, the Erymanthian boar. The boar comes to carry them further on to San Francisco. It takes them to the junkyard of the gods, and Percy meets Ares and talks to Aphrodite (a private conversation which the other questors did not hear).

Eventually, the group enters the junkyard, where Bianca tries to take something (for Nico), but she awakens a defective Talos and enters via a maintenance hole in his left foot to destroy him. She succeeds in destroying Talos, but goes missing (It is later confirmed that she had died). Zoe and the other questors are devastated and searches for Bianca to no success. All of them realize that Bianca was the one they would lose in the land without rain. They go to see Annabeth's father in San Francisco to ask for help and he lends them his car, which cannot be returned to him as it explodes due to a lightning bolt that Kronos threw to make Thalia angry at her father. Thalia is shaken by this, thinking that Zeus tried to kill her, remembering the part of the prophecy one shall die by the parent's hand, but Percy comforts her and tells her it is just Kronos, trying to make her angry with her father. His words convince her, and she manages to stay focused.

They all then climb to the Garden of the Hesperides, where Zoë meets her sisters and is poisoned by the dragon, Ladon. They continue to the place where Atlas used to hold up the sky, and they see Artemis taking on his burden. Annabeth is bound and gagged by Luke and Atlas.

They discover that Kronos used Thalia to twist destiny into her hands, since she would be turning sixteen on the day following the Winter Solstice.

Thalia demands answers from Luke, as to why he has betrayed them all, and Luke tries to pacify her, but she takes out her spear and says," you're not Luke, I don't know who you are anymore." and attacks him.

Thalia and Luke battle each other fiercely, fierce anger on Thalia's side, desperation on Luke's. Thalia gained the upper hand in the battle. Thalia manages to disarm him, saying that he could never beat her. Luke tries to grab her weapon, and as a pure instinctive reflex, Thalia kicks him, and Luke falls into a chasm. She is very shocked and sad, having tears in her eyes having done so, that she just killed Luke, but it is confirmed by Poseidon that the traitorous demigod had survived. Thalia decides to become a hunter of Artemis at the end of the book so she would not be the one of the prophecy.

The Battle of the Labyrinth
Thalia was absent from Camp Half-Blood this summer due to her adventures with Artemis and the Hunters, but she is mentioned once by Percy when talking to Hera, the goddess of marriage, about Zeus and Ms. Grace's past relationship.

The Demigod Files
Thalia appears in The Sword of Hades along with Percy and Nico. She is hunting a wild animal in the city when she bumps into Percy and thinks it is very strange that they bumped into each other. Nico soon arrives in a shadow and Thalia knows something is wrong, but cannot react quick enough as the three demigods are dragged into the Underworld. When they arrive, Persephone makes it known that she was the one that brought them together and needs them for a quest. She claims that Hades has made a new symbol of power in the form of a sword, but it had been stolen. Thalia doesn't want any part of the quest, feeling that a new symbol of power will tilt the balance of power between the big three gods. However, if the sword escapes the Underworld, it could fall into the hands of the Titans and be used against them. Thalia agrees to help and the three chase after the sword. They question Sisyphus, but while they ask him about the thief, Thalia holds the rock and begins pushing it up the hill. She almost makes it before it begins to roll back down the hill. She lets go and the rock rolls back onto Sisyphus who is forced to continue his punishment. Thalia tells them that she almost had it and wanted to try again as if it was part of the punishment. They continue to chase Ethan (who they discover was the thief) and eventually get the sword back. After Nico decides to stay in the Underworld, Thalia invites Percy to a place that has amazing cheeseburgers, which he agrees to.

The Last Olympian
Thalia and the Hunters come to New York City to help the campers fight off Kronos's army, and the Campers are very relieved to see them. Thalia says she has been on a great many adventures, and she, Annabeth, and Percy promise to buy cheeseburgers after the battle and talk about what they've been doing since they saw each other last.

Thalia goes with Percy, Annabeth, and Grover to Mount Olympus to defeat Kronos, but she ends up getting left behind when a statue of Hera that was actually intended to fall upon Annabeth, falls on her instead. However, she appears to have survived and continued to work in Artemis' Hunters, and will presumably be immortal for the rest of time, unless, she falls in love or dies in combat, or if she decides to leave, as her joining the Hunters was only to escape the Great Prophecy.

The Lost Hero
Thalia was mentioned in the beginning to be searching for Percy with the Hunters. Later she was talked about when Jason being a son of Zeus (Roman counterpart: Jupiter) sees a picture of her in Cabin One to which he stares at before Annabeth comes in. After a conversation about Thalia's past life with Annabeth and Luke, Jason asks what her last name was to which Annabeth responds "Grace". After remembering his dream about Lupa saying he was their "saving Grace", Jason claims to be her brother. Later on in the story, after Jason meets Lycaon king of the wolves, Thalia and the Hunters kill some of Lycaon's wolves and managed to injure Lycaon himself before they fled. After sending Piper and Coach Hedge off to Phoebe to heal Piper's injuries Thalia and Jason talk about Jason's life before he disappeared.

After their talk about Jason's life they move on to Jason's quest and how they can get to Aeolus. Thalia shows them the way to Aeolus' palace but splits up with Jason, Piper, and Leo to join the Hunters to protect Hera so that while Jason's group could rescue Piper's dad, the Hunters could protect Hera until Jason arrives. While Jason was away to see Aeolus, Thalia and the Hunters were attacked by Lycaon and his wolves. After Jason gets back with Leo and Piper from saving Piper's dad they meet up with Thalia, who says nothing worked on the cage and they should just leave Hera. Hera and Thalia fight, ending with Thalia leaving, but first she tells Hera every bad thing she did to children of Zeus, ending with Thalia reminding Hera that they are at the spot when Hera took Jason. Later, Jason, Piper, Leo, and Thalia were ambushed by Khione and Thalia was frozen by her, along with the rest of the Hunters. Soon after Thalia was frozen, Leo fought Khione while Jason and Piper battled and defeated the venti and the Earthborns. Quickly after, the Giant Porphyrion was reawakened by the powers of Gaia and Hera was being buried by Gaia. Like the prophecy Jason had recieved "The forge and dove shall break the cage", Leo, a son of Hephaestus (forge) and Piper, a daughter of Aphrodite (dove), worked together to break Hera's cage with Leo trying to saw off the lock of the cage while Piper used charmspeaking to slow Gaia down.

Meanwhile Jason was distracting the Giant Porphyrion taking him on barehanded. While Jason distracted the giant, Leo and Piper finally broke Hera's cage free. The fight between Jason was quickly over with Jason on the floor and Porphyrion's spear at his chest. Just before Porphyrion struck, Hera quickly assumed her Divine Form while telling everyone to look away. Jason was too tired and was nearly killed. Thalia is then seen telling Hera to save Jason. After Piper telling him to awaken, he did as everyone around him gathered. As Jason got up, Hera was arguing with Thalia but Piper told them to stop. Before Hera sent Jason, Piper, and Leo back, Thalia had told Jason she would attend the council meeting at camp. At the council, Thalia didn't show up but Chiron had said she had other matters to attend to. Thalia also gave Piper a Hunter of Artemis card to join, but Piper burnt it for Jason.

Relationships

 * Luke Castellan - It was hinted that before Thalia became a Hunter that she and Luke had a romantic past, that was changed when Luke betrayed the Camp in The Lightning Thief.
 * Annabeth Chase - In The Lost Hero Thalia called Luke and Annabeth her best friends, and it was shown in The Titan's Curse that Thalia was extremely worried about Annabeth when she was abducted and wanted to rescue her.
 * Percy Jackson - Like their fathers, Thalia and her cousin Percy share many similarities. Despite their tendency to fight, they consider each other close friends. It was Percy who was the first male that Thalia hugged after officially becoming a Hunter, saying "I am honoring a friend".
 * Jason Grace - Jason is Thalia's little brother. It was seen in The Lost Hero that she loved Jason very much and that it almost killed her when Jason was sent away. She also said that what happened with Jason had hurt her so much that she never mentioned Jason to Annabeth or Luke, her two most trusted friends.
 * Ms. Grace - Thalia has a very rough relationship with her mother, and that she was always drunk and acted like a spoiled child. Thalia's lack of patience was part of the reason Thalia ran away; the other reason being losing Jason. Thalia's mother eventually died in a drunk driving accident.
 * Artemis - Thalia remains loyal and obedient to sister Artemis. It was stated by Jason that Thalia had found a family in the Hunters and a mother in Artemis.
 * Zeus - Thalia and Zeus aren't close, but in the ending of The Titan's Curse, it was shown that Zeus was proud of Thalia.
 * Hera - Like every illegitimate child of Zeus, Thalia is detested by Hera. When they encounter each other, Thalia quarrels with her stepmother. During The Last Olympian, Hera purposely made a statue fall, aiming for Annabeth but Thalia jumped in the way and was pinned down to the ground. Thus, she was unable to help in the fight against Kronos.
 * Grover - Thalia gets along with Grover reasonably well. Grover was the first Keeper that was supposed to deliver Thalia and the other two half-bloods (Annabeth and Luke) to Camp Half-Blood but failed to do so. As a result, Thalia had been forced to confront a massive amount of monsters that were hunting them down. Though extremely powerful, Thalia was overwhelmed by their numbers and perished. However, her father Zeus took pity on her and turned her into a pine tree. The tree, later known as "Thalia's pine," served as a magical barrier to Camp Half-Blood. Once Thalia was alive again, Grover and Thalia's friendship remained strong.

Powers and Abilities

 * Thalia can send powerful amounts of static shock throughout another person's body on contact. She can emit static sparks, like Jason, which are described as being blue.
 * Thalia can manipulate the Mist, which means she can make things appear as she wants them to appear to the eyes of a mortal (taught to her by Chiron).
 * Things that belong to her father's domain can do as she asks, such as statues of the angels in The Titan's Curse, which were gifts to her father. They, on her request, flew her and her friends to San Francisco.
 * Thalia has a strong leadership quality, possibly a result of being the daughter of Zeus.
 * Thalia has electrokinesis (control over electricity and lightning) due to her father, Zeus, the god of lightning. Calling down lightning bolts are a lot harder than emitting static, as it makes Jason ready to faint.
 * It is assumed that Thalia has aerokinesis (the ability to control air) like her brother Jason Grace, as her father Zeus is Lord of the Sky, but has not used it nor even tried it due to her acrophobia, fear of heights.
 * Thalia became Artemis' lieutenant (replacing Zoë Nightshade) in the end of The Titan's Curse, and as a result she is immortal, unless she falls in battle, chooses to leave, or falls in love.
 * ADHD, which actually is heightened alertness that keeps half-bloods ready and alive for battle.
 * Dyslexia, since her brain is hard-wired for reading Ancient Greek instead of modern languages.

Appearance
Thalia has shoulder length spiky black hair, electric blue eyes (though they are "stormy green" in Percy's dream of her in The Lightning Thief and stormy blue in Percy's dream in The Sea of Monsters ), and freckles across her nose. She is described as being "extremely pretty" by fellow campers and Apollo, (in The Titan's Curse, when he says "Man, I hate it when pretty girls get turned into trees,") and is "beautiful", according to Artemis. She wears punk styled clothes. She wears a magic bracelet that turns into Aegis, a modified version of Zeus's shield, a gift from Athena. In the books, Percy describes Thalia's shield to have the head of Medusa imprinted in the center to strike fear into her opponent's hearts. Many campers and monsters cower at the sight of Medusa's head on Thalia's shield. Thalia also carries a collapsible mace canister which changes into a spear.

Thalia has been described as "punk" or "goth" with a forever present silver circlet on her head, which looks like a tiara and according to Percy, symbolizes her position as the first lieutenant of the Hunters of Artemis. As a Hunter of Artemis she wears a silvery parka. In The Last Olympian she was wearing a "Death to Barbie" T-shirt, with a picture of a barbie doll with an arrow going through its head, following with some skull earings to go along with her shirt. According to Percy, it did not match the silver circlet in her hair at all.

Thalia makes another appearance in The Lost Hero, where Leo, upon immediately seeing her, developed a crush on Thalia. He thought Thalia was way too pretty to be Jason's sister, and over the fire, Leo thought she looked like the goddess Khione, just as cold and beautiful. Leo also states that "Nahh, (while assuring Jason) we were absolutely destined to meet your hot sister," although Thalia ignored this completely. Of course, Thalia is a Hunter of Artemis and has sworn off boys.

Personality
Thalia is a brave, strong and caring girl, though stubborn, prideful and assertive. In some ways she's very similar to Artemis.

Weapons

 * A copy of Aegis that expands from a shiny silver metal bracelet that she wears on her wrist, which many of the campers and monsters cower. In front, it has a picture of Medusa's head in the middle of her shield.
 * A collapsible spear that expands from a Mace canister that she uses to direct her powers.
 * A Hunter's bow after joining the Hunters.
 * Two hunting knives that she can use to direct electric blasts.

Fatal flaw
Thalia's fatal flaw is that she has a weak resistance when she is offered power (mirroring Zeus's power struggle with his brothers, as she also conflicted with Percy over capture the flag). She is also afraid of heights (acrophobia), a quality Percy finds strange and funny, as her father is the Lord of the Sky. In the short story, The Sword of Hades, in The Demigod Files, she also shows to be very determined. Thalia has trouble abandoning a difficult task that she has started but is not able to complete.

She also feels massive amounts of guilt about her brother going missing when he was little, as she more or less raised him on her own (her mother was unstable); she had believed for years that her mother had killed or abandoned him on a family vacation. She never told anyone about this when she ran away, not even Luke or Annabeth.

The Lightning Thief
Although she is never actually mentioned in the movie, her tree appears and she is also mentioned in a deleted scene by Grover.

Trivia

 * If Thalia had never been turned into a pine tree, according to her date of birth, she would be 21, so the prophecy would have landed on her, not Percy, but her aging slowed during her time as a tree, so at the conclusion of "The Titans Curse" she had not yet reached 16 years of age. Consequently, upon joining the Hunters of Artemis, she is a day younger than 16 years of age, leaving Percy responsible for the Great Prophecy.
 * Thalia's Name comes from the 1 of the three "Graces" "Thalia", hence the name Thalia Grace
 * Thalia, ironically, has a fear of heights even though her father, Zeus, is the god of the sky. She learns later in The Lost Hero that her full blood brother Jason can control the wind patterns long enough for him to 'fly'.
 * Since Zeus' godly children are Persephone, Ares, Hebe, Eileithyia, Apollo, Artemis, Hermes, Athena, Dionysus, Hephaestus; any of their offspring would result in Thalia having numerous nieces and nephews. This would result in the Ares, Apollo, Hermes, Dionysus, Hephaestus and Athena's cabins having Thalia as an aunt. Also, this makes Annabeth her niece, Luke her nephew, Percy Jackson, Nico and Bianca di Angelo her cousins because Poseidon and Hades are Zeus' brothers. Since all the other 11 Olympians except Poseidon, Hades, Hera, Demeter, and Aphrodite were children of Zeus, nearly all half-bloods at Camp before the Last Olympian are related to Thalia and Jason. However, all the Olympian gods are considered one generation, so they are considered as cousins.
 * Her favorite food might be cheeseburgers since she always offers to buy cheeseburgers to her friends.
 * It is unknown if she can fly
 * Thalia's last name wasn't learned until The Last Olympian. According to Percy, it made her seem almost normal, and less mysterious and powerful.
 * Percy said that Thalia gives evil looks like mentioning Thalia's mother.
 * In the Sea of Monsters, Thalia is said to have green eyes when she is revived from being in tree form, but in the following books she has blue eyes.
