General Mandible

General Mandible is the main villain in the 1998 computer-animated film, Antz, voiced by Gene Hackman. He is the leader of the ant army and is similiar in some ways to Hopper from A Bug's Life.

Captain Mandible was the leader of the army ants but was always a war-hungry insect with little regard for the colony as a whole: as was evident when he ultimately betrayed it and attempted to flood the colony to kill all the ants inside it, including the queen - ultimately the would-be-dictator had his plans ruined when he engaged in a confrontation with the heroes of the story, resulting in him falling to his doom (like many villains do).
