|“||I'm the son of Jupiter! I'm a child of Rome, consul to demigods, praetor of the First Legion. I slew the Trojan sea monster, I toppled the black throne of Kronos and destroyed the Titan Krios with my own hands. And now I'm going to destroy you, Porphyrion, and feed you to your own wolves.||„|
|~ Jason's boast to Porphyrion|
The younger brother of Thalia Grace, Jason Grace is one of the main protagonists of the Heroes of Olympus series of novels. He was born on July 1st and is the son of Jupiter, the Roman aspect of Zeus, and a mortal actress. He was born seven years after Zeus fathered Thalia, his Greek aspect. Because his father had consecutively sired two children with his mother, Juno, the Roman aspect of Hera was made Jason's guardian to placate the indignant goddess and Jupiter went even as far as to name his newborn son after his wife's favorite hero, Jason.
When he was two years old Juno ordered his mother to take him to the Wolf house. There he was separated with him family and initiated by Lupa, the caretaker of Romulus and Remus, he was taught the ways of Rome and after training sent him to Camp Jupiter to be raised in the life of the Roman Legion. Later he became the Centurion of the Fifth cohort and performed quests for the legion and the gods. Few details are given on what quest he performed during his stay in the legion but it is known that is accomplishments include leading a quest to find and slay the Trojan sea monster, which included him staying at Aeolus's palace for a few days, doing a favor for the god Bacchus involving a missing leopard in Sonoma, and going on a quest with Reyna to Charleston to retrieve a stash of Imperial Gold torpedoes from the C.S.S. Hunley at Fort Sumter. Some time during these quests he received Ivis, a coin that when flipped would either transform into an Imperial Gold spear or sword depending on what side it faced, but this was destroyed during his quest to save Hera. However, he was given an Imperial Gold gladius from Juno which has the ability to transform into a Pilum, the Roman Javelin.

Attack Potency: Island level (As one of the big three demigod children, he should be comparable to Hazel Levesque, who was able to destroy a small island; fought Percy Jackson on even ground while both were controlled by Eidolons, defeated Krios single-handedly as well as Enceladus and Porphyrion with the help of Zeus, since Giants can only be defeated when Demigods and Gods work together)

Intelligence: As the former Praetor of the Twelfth Legion and a son of Jupiter, Jason is a force to be reckoned with in combat. Along with Reyna, he led the assault on Mount Orthrys before defeating the Titan Krios in single combat, a feat only matched by Heracles. Even with most of his memories missing, he still managed to defeat the giant Enceladus with the help of Leo and Piper, and is able to duel Percy Jackson, who brought down Hyperion and Iapetus, on even ground.
Weaknesses: As a demigod, he can be slain by both conventional and supernatural weapons. He can be plagued by doubt and harshly criticizes himself whenever he makes an error. Using his demigod powers extensively drains his stamina.
- Killed the Trojan sea monster
- Led the Twelfth Legion in an assault on Mount Othrys where he fought through an army of Scythian dracanae and defeated the Titan Krios himself
- Sent Porphrion flying with air blast
- Fought six Giants and killed them, albeit with some help
- He killed Enceladus with the help of Piper, Leo and a lightning bolt from Zeus.
- He killed Otis and Ephialteswith the help of Percy Jackson, Bacchus, and Leo.
- He killed Clytiusalong with Nico, Piper, Hazel, Frank, and Hecate.
- He helped Kymopoleia kill Polybotes. He fought alongside Zeus to kill Porphyrion.
Aerokinesis: As a son of Jupiter, he can control and manipulate the air.
- Air Blasts: He can control, and generate very powerful winds and air currents, enough to send Giants flying.
- Venti Control: He is able to dominate the will of more chaotic Venti.
- Ropes of Wind: He can generate ropes of wind, "more tightly wound than any tornado", to bind his foes.
Atmokinesis: As a son of Jupiter, he can control the weather, generating fierce thunderstorms at will and with much greater ease than a child of Poseidon.
Electrokinesis: As a son of Jupiter, he can control lightning and electricity and thus call down lightning bolts powerful enough to smash through insulated windows, emit arcs of static electricity form his hands, and shock opponents with physical contact. In addition, is able to pick his targets, electrocuting Polybotes' basilisks while leaving Percy Jackson, who was standing in the water with them, unharmed. By extension, he's also completely immune to the effects of electricity, being unfazed after channeling enough electricity to kill twenty people. However, using this ability extensively drains his stamina.
