Being the youngest member of the group, he is always trying to prove himself. His actions can come off as arrogant, but his intent is to show that he can handle himself. As a kid he spent most of his time playing video games, tabletop games and watching anime.
After the incident which left him, and the rest of the team, with their new abilities, he spent time adjusting to his powers. As the only member of C.R.I.T. to have any physical changes, he had to learn to control them. His eyes became purple, which he could pass off as contacts, but his heroic form caused his face to become engulfed in ethereal flames. People not familiar with him confused him with being a villain or anti-hero, so he donned a mask to help cover his lower face.
Whether by fate, chance or sheer dumb luck, Spectre gained the attention of the powerful entity Semedi; the talking, drinking, smoking cat. Their bond allows Semedi to enhance Spectre’s powers and open him up to abilities he doesn’t know he has.
