Percy Jackson and the Olympians: Legends

Octavian was a tall, skinny 18-year-old youth with blond hair, crazed blue eyes, and skin as pale as Nico's. It is also mentioned that Octavian reminded Percy of someone, it is unknown which character this refers to. Octavian usually insists he resembles his namesake, Augustus Ceaser, who was known as Octavian. He often held a ceremonial knife and stuffed animal on hand. His tattoo was composed of a lyre, the symbol of his ancestor Apollo, with SPQR inscribed above seven lines which represented seven years meaning that he had been attending Camp Jupiter since he was about eleven. Octavian's usual attire consisted of a white toga over a baggy shirt and jeans or cargo pants.

Octavian was an arrogant, jingoistic, condescending, Machiavellian individual. Much like the Roman ideal, he was ambitious and followed the rules, at least on the surface. Unfortunately for anyone who crossed him, Octavian was highly intelligent, callous, cunning, and manipulative. Octavian was deeply knowledgeable of Roman history, including the fact that the Greek demigods were once enemies of the Roman ones. At times, he is portrayed as a potential threat if one became enemies with him. Percy Jackson, however, is unimpressed by him. Octavian was shown to be ruthless, perhaps even sadistic, as he did his best to painfully burn Percy when giving him his SPQR tattoo. Octavian seemed to value cruelty in others too, since he allied himself with the infamously brutal Bryce Lawrence, and also wanted Nico di Angelo as an ally, since he claimed to see a decent amount of ruthlessness in the son of Hades, which Octavian greatly appreciated.

Octavian was a Roman legacy of Apollo and the Augur of Camp Jupiter. He was one out of several people to have the gift of prophecy. Octavian was also a centurion in the First Cohort. Incredibly ambitious, Octavian rose though the ranks and eventually became the co-centurion of his cohort. He gained the position of Augur during this time as well. After the disappearance of Jason Grace, he began activity aiming at becoming praetor, gaining support from some and blackmailing others in an attempt to be elected into the position. During the Siege of Camp Half-Blood, he dies after accidentally shooting himself out of an onager aimed towards Leo Valdez, who was making sure Gaea was destroyed, therefore helping to defeat her.
