Eva is a character who coaches new players in Mutants: Genetic Gladiators. She also acts as one of the game's mascot characters. Her name is short for Eva Destruction.
Eva wears a black businesswoman's suit with an open white shirt. She also has a string necklace with what appears to be a Mutant larvae on it.
She is now your coach but formerly she was a Psy-Captain before Baron Urban defeated her. It is revealed as the story progresses that Baron Urban had modifed his own genes with the Mythic gene and was able to completely remove Eva's ability to control her mutants in combat, rendering her useless as a Psy-Captain and forcing her into retirement.
