His tongue is snake-like, and his teeth are jagged. Likes: Helping people, adventure and fighting, sunbathing, Jake. Dislikes: Being treated like a fake, his own violent impulses, Finn.

First person: I (soft, polite) Second person: You / Name Abilities/Strengths: Can fight by transforming his body to suit the situation without needing weapons. Has limited regenerative abilities.
