Generator Rex:brRex is a fifteen-year-old (sixteen, later on in the series) amnesiac teenager who is an E.V.O. Unlike most E.V.O.s, he lacks any physical deformation but forgets about his past. He is also able to control his active nanites, allowing him to manifest a wide variety of various bio-mechanical abilities and powers. However, Rex is truly unique because he has the ability to deactivate nanites inside other E.V.O.s..
