Vile is an arrogant and violent individual. Though he used to be a Special A class member of the Maverick Hunters, Vile had an abnormality in his electronic brain that made him ruthlessly hunt down Mavericks and totally annihilate them, without regard for collateral damage. Due to being a borderline Maverick, he was removed from duty and detained, being freed during Sigma's rebellion so he can cause as much destruction as he wishes. Despite his callous and unruly nature, he is still a clever fighter, carefully retreating after Zero damages his Ride Armor and later trapping him in a cage to keep him out of the way.
