Malice looks like any other Appoplexian, though he is shorter and thinner than Vexx and has a kind of mane/crest on the top of his head. He wears punk/wrestler type outfit.
Like all Appoplexians, Malice's personality is argumentative, stubborn, and extremely fixated on solving all his problems with violence. He is much like Rath, even down to his speech mannerisms.
One specific quirk about his personality is the fact that he doesn't like feeling anything, especially feeling hungry. He is also very fond of burgers cooked animal-style with lots of onions.
Malice first appeared in Food Around the Corner. He attended a peace conference between the Appoplexians and the Lewodans, with Ben (as Gravattack) acting as a mediator. One of the Lewodan dignitaries attempts to sabotage the conference and kill them all, but is stopped by Ben, and the two sides reach a peaceful resolution.
He returned in the episode No Honor Among Bros, as a participant of the Golden Fist Tournament and the opponent of Ben Tennyson. Malice told Ben that even though he saved him and his people, he is angry because he prevented centuries of brutal warfare. Ben turned into The Worst, and after three hours of pointless punching, kicking and biting, Malice became exhausted and gave up the match.
