Killbots

A killbot is a type of robot, which is programmed for one purpose: Killing. For unknown reasons, a kill limit of 999,999 was hardcoded into the killbots.

Zapp Brannigan once faced a horde of these killing machines. However, he defeated them by sacrificing waves of his own men, until the killbots' kill limit was reached. When the kill-limit is reached, the killbots become rather friendly. However, their kill counter has the option of being reset, which reactivates their need to kill.
