Jason Grace is one of the main protagonists of the second Camp Half-Blood series, The Heroes of Olympus. He is a Roman demigod, a son of Jupiter, and full blooded brother to Thalia Grace. He is a former praetor from Camp Jupiter.

History
Jason is the son of Jupiter and the mortal Ms. Grace. His older sister is Thalia, his mother's daughter by Zeus (Jupiter's Greek counterpart) who raised him in the absence of their alcoholic mother. When he was two years old, Jason was turned over to Juno (Hera) who placed him in Lupa's care. Jason was raised in the Fifth Cohort of Camp Jupiter from the age of three. There, he became friends with Dakota, Gwendolyn, Hazel Levesque, Bobby, and most particularly, Reyna.

While the Greek campers, headed by Percy Jackson, protected Manhattan and brought the downfall of Kronos, Jason headed the Roman attack on Mount Tamalpais and defeated Krios by himself. After that, he became the praetor of the Twefth Legion. One month later, he is switched with Percy.

The Lost Hero
Jason wakes up on a bus belonging to the Wilderness School holding hands with a girl he doesn't even know. He finds that he has no memory of even going to the school or having a best friend named Leo and a girlfriend named Piper. Gleeson Hedge, his supposed gym teacher and satyr protector (though Jason doesn't know that yet), tells him that he's never seen him before today and that the Mist has been manipulated to make everyone think that they know him. He also reveals that he, Piper, and Leo are demigods and that an extraction team (Annabeth and Butch) is coming to get Piper and Leo to camp along with an unknown "special package", which turns out to be Jason. This story is confirmed when Jason sees Leo make a working mechanical helicopter out of pipe cleaners. Later, an unnaturally powerful storm arrives, and the class bully Dylan revealed himself to be a Ventus or Venti (storm spirit), Greek form anemoi. Jason instinctively took out his gold coin (Ivlivs), flipped it, and it became a well balanced sword made of Imperial Gold. While he and Piper fought off Dylan, Hedge (who revealed himself to be a middle aged satyr) climbed down the canyon wall to retrieve Leo when he was thrown down. Jason also survived a lightning bolt with which Dylan attacked him that could have killed twenty men, blowing off his shoe and when Piper is thrown off the sky-walk Jason jumps after her, discovering that he can manipulate air. After a long battle, Dylan takes Hedge away and leaves Leo, Jason, and Piper on the canyon sky-walk. Just then two half-bloods arrive on a chariot pulled by pegasi; a guy named Butch, son of Iris (the Rainbow goddess), and Annabeth, daughter of Athena. When Annabeth and Butch notice Jason only has one shoe on (as the other one was blasted into bits by the lightning bolt), Butch tells them that Annabeth had a vision that a boy with one shoe would help her find one of the campers, who has been missing for three days, her boyfriend Percy Jackson.

After they arrive at Camp Half-Blood, Annabeth gives Jason and Piper a tour of the camp. Jason then meets Chiron who immediately realizes who Jason is by speaking in Latin, to which Jason responds in Latin. Afterwards they find out Hera is in danger, and Jason must lead a quest in order to save her. Jason reveals his parent god through a lightning bolt, showing that he is a son of Jupiter. He chooses Piper, who is now claimed by Aphrodite, the goddess of love, and Leo, who was claimed by Hephaestus when they got to Camp Half-blood, to go with him on his quest. Jason also receives a Prophecy saying that he must beware the earth, possibly because Gaea, the Earth, is his enemy and that she bears arms to the Doors of Death. He meets Medea, a mortal who was supposed to have died more than 3000 centuries ago. Later, Jason and his companions meet another mortal who was supposed to have died millions of years ago, Midas. King Midas, the king who wished for the golden touch, then learned to bring back people from their golden state, running water. Midas quickly turns Piper and Leo into gold statues. Jason retaliates by summoning a lightning bolt to destroy Midas.

Then Piper reveals that she was in fact the traitor because her father had been kidnapped. Jason and Leo resolve to rescue him, even though it jeopardises the quest. In a mountain, they find Enceladus, the giant born to kill Athena. Jason faces off against Enceladus and manages to wound him several times. However because of his strength, Jason cannot kill him as it would take the power of a God and demigod. Jason's gladius breaks releasing a lot of energy but fails to kill Enceladus. Jason calls on Zeus to save him and his faith rewarded with a incredible lightning bolt, killing the giant.

Hedge takes Piper's father home while the three continue on their journey.

When he, Piper and Leo arrive back at camp, he is visited by Juno when he is in his cabin alone, and is given a new gladius as a replacement for the one he lost while fighting the giant, Enceladus. After this, a head counselor meeting was called, where he then revealed that he is from a Roman equivalent of Camp Half-Blood, and that is where Percy is most likely at. Jason also reveals that if the campers at the Roman Camp discover that Percy's from Camp-Half Blood, they may not be that nice. It is decided that he, Leo, Piper and Annabeth will go and find Percy at the Roman Camp and then set sail for Greece by sailing on the Argon II.

The Son of Neptune
Jason is mentioned throughout the book by the campers of Camp Jupiter, because they've been wondering where he has gone.Percy has a brief dream vision of Leo working on the Argo II with Piper and Jason behind him. As well, when Percy, Frank, and Hazel are watching Polybotes's from afar Ma Gasket (from the Lost Hero) yells, "The camp, yes. Vengeance! The orange and purple ones destroy my home. Now Ma Gasket will destroy theirs! Do you hear me, Leo? Jason? Piper? I come to annihilate you!"

Personality
Jason is a serious young man with a moderate sense of humor. He also has a strong sense of honor and justice as shown by his great compassion and loyalty. Though a natural leader, Jason can be plagued by doubt and criticizes himself whenever he makes an error.

Appearance
Jason Grace is described as average looking having the features of a Roman Statue, with electric blue eyes, tidily/military cropped blond hair, and a small scar on the corner of his lip from trying to eat a stapler when he was two years old . He is of shorter height with an medium build, having muscular and tanned arms. His tattoo has the picture of an eagle with SPQR and twelve lines, indicating he has been at Camp Jupiter since he was three years old.

Abilities

 * ADHD: Like all demigods, Jason possesses inborn supernatural battle reflexes and senses that he uses to analyze the fighting style of his opponent.
 * Fighting Skills: Jason is an expert spearman and swordsman due to his legion training.
 * Dyslexia: Jason's brain is hardwired for Latin (although strangely, in The Lost Hero, he could read King Midas' pamphlet for investing in gold just fine. This is possibly because he is a Roman demigod, and because Latin and English are very similar, so he may not even have dyslexia).

Demigod Abilities
Being the son of Jupiter; Jason holds divine authority over the creatures of the sky as well as weather, having powers that are greater than the children of nearly every other god and he may have the ability to talk to the eagles, as his father sacred animal are the eagles.
 * Aerokinesis: Jason can control the forces of the atmosphere such as:
 * Manipulating air currents allowing him to fly.
 * Sensing wind magic (e.g. Aeolus's vapor trail).
 * Dominating the will of Venti,as they are wind spirits.
 * Electrokinesis: Jason can control the forces of electricity such as:
 * Calling down lightning bolts.
 * Send powerful amounts of static shock through someone's body through physical contact, can also emit static sparks, which are described as being blue.
 * Shooting arcs of electricity capable of shocking or stunning someone (Thalia has this power, so Jason would likely too).
 * Resistance to high voltage electricity. Although his exact limit is never stated, Jason can handle enough electricity that would kill twenty grown men, as shown while fighting Dylan.

Magical Items

 * Ivlivs, a coin made of Imperial Gold, it turns into a golden sword on heads or a golden javelin on tails when flipped. The weapon hasn't been named yet in the series, but the coin has the word 'Ivlivs' on it, which is Latin for 'Julius.' It was destroyed by Enceladus during the fight on Mount Diablo.
 * Juno's Gladius which she gave him after the coin was destroyed towards the end of The Lost Hero. Likely made of imperial gold.

Jupiter
Zeus sired Jason, his second child with Ms. Grace in his Roman aspect. Like all the Roman Gods, Jupiter rarely involves himself in the life of his child. Although it is unlikely that he has ever met his father, Jason is still given his aid when it is most needed.

Ms. Grace
Since Jason has forgotten his memories, we can imply that he wasn't taken care of by his mother, since Thalia said that she was the one who took care of him until Ms. Grace gave Jason away to Hera's Roman form, Juno.

Thalia
Jason's sister, Thalia Grace, was born by Zeus. Thalia is a Greek demigod, because when Zeus visited her mother the first time, he was in his Greek form. When Zeus came to Jason's mother for the second time, he came in his Roman form, Jupiter. Jason is therefore a Roman demigod, while his sister is Greek. It is shown that Jason cares for his sister. He feels somewhat depressed that Thalia has found a new family in the Hunters of Artemis. However, its shown that when Jason first saw her picture and Annabeth told him her last name, his instincts told him she is dangerous, as Juno left enough memory to know that digging up his past could be disastrous and that she was his sister.

Piper
She and Jason share many romantic moments throughout The Lost Hero. He has much concern for her, as he does everything to help her, such as when she says they should get together he says in his thoughts together, yes. He puts his hand on her waist to support her when she collapsed due to hypothermia. At the end of The Lost Hero, she and he, have a romantic moment at the end of which they repeat what they said in Piper's Mist induced memory of them kissing. Also, Jason really likes Piper, but he is worried for their future.

Reyna
The memory of her makes him rethink what he is doing with Piper, though he does not know why. It's revealed in The Son of Neptune by Reyna to Percy that if Jason hadn't gone missing ,a romantic relationship would have developed, since Reyna said that it wasn't uncommon for there to be romance between praetors, since they work together so much. Also, when the Argo II arrives in the sky Reyna says that she hopes Percy is right and Jason is aboard the ship, stating that she has missed him.

Leo Valdez
The Mist gives Leo and Piper fake memories that they knew Jason for months. However this doesn't stop Leo from seeing Jason as his friend and works on a way for Jason, Piper, and him to gain transportation (Festus). While Jason thinks that Leo is kind of weird ar first in The Lost Hero, during their quest, he and Leo became very good real friends.

Bobby
Jason starts to remember him at the end of The Lost Hero. When Juno returns some of Jason's memories, he remembers several of his friends, with Bobby being one of the names mentioned. Not much is known about him but his name.

Hazel
Jason remembers her in the last part of The Lost Hero as being his friend back at the Roman Camp. She is one of the main characters in The Son of Neptune, and parts of the book are in her point of view.

Gwendolyn
Because Jason kind of remembers her, it can be assumed they had been friends. Nothing else is known about her yet. In The Son of Neptune, she was a Centurion of the Fifth Cohort, but after the position was given to Frank, she retired after ten years of service to attend college in New Rome.

Dakota
A Centurion of the Fifth Cohort, he and Jason were friends at Camp Jupiter.

Percy Jackson
While Jason has yet to meet Percy, he has heard much about him. It is unknown yet what Jason and Percy will think of each other.

Annabeth Chase
Jason likes Annabeth as a friend, but has no romantic feelings towards her.
