Malevolence is a Galvanic Mechamorph and former dictatorial ruler of the Mother System. Following an uprising, his successor negotiated with the Plumbers to use Null Void Incarcecon as the impregnable prison of choice. He debuted in Back in Action: Alien Universe episode Revelation.
Malevolence is a purple-patterened Galvanic Mechamorph. In the Null Void Incarcecon prison, he is shackled by an inhibitor collar. As of Leaked, he is missing his right arm.
Malevolence is ruthless and demands attention as a leader. He is borderline insane and insanely cunning, to the point where he dismembered his arm and acted like it was his child so that that part of him could escape the impregnable Null Void Incarcecon.
