The mysterious future-Predacon Antagony is the Herald Maximo of the fearsome Predacon warlord Shokaract, second only to Shokaract himself. She is utterly ruthless and without a shred of pity or mercy, and harbors a secret death-feud against the upstart Predacon Cataclysm who threatens her position. Though utterly loyal to Shokaract, she will do anything short of open revolt to make sure she remains the Herald Maximo. Antagony's armor makes her virtually invulnerable to pain and it has been speculated that she enjoys inflicting it so much just so she can attempt to understand the utterly alien sensation.
