The war machine Destructor was "trained" by Phnog to appear in the Ultimate Robot Fighting League, and fight Bender. Phnog however cheated by controlling Destructor from underneath the ring. Phnog was exposed by Leela, but Destructor won the fight, ending Benders' career in the ring, and necessitating a lengthy repair job.
Destructor is an enormous armoured tank, and his use in battle has been ruled a war crime due to his vast destructive potential. During the Robot Revolt of 3001, Destructor indulged in a great deal of wanton damage to the city of New New York, before the rebellion was finally called off by Mom, following her seduction by Professor Farnsworth.
