Extro has the ability to morph his plastic body into whatever he envisions. As punishment by a powerful sorcerer, Henry Hullmaker’s soul was entrapped inside a 3d printed plastic sculpture were he was to remain frozen for all time.
A rival sorcerer unsuccessfully attempted to reverse the spell, but it resulted in his ability to control the shape of his plastic body when heated. With the help of an exosuit forger, experimental armor was created to regulate the heat required for transformation to occur.
The heated body armor he wears allows him to quickly change the shape of his plastic form, as well as instantly solidify his plastic shape into a hardened state. Kids call him “Plaztico” and really like that he smells like popcorn.
