Killbots

A Killbot is a type of robot programmed for one purpose: murdering organic life forms. 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 millions of his own men, until the killbots' kill limit was reached. When the kill-limit is reached, killbots become peaceful and in fact rather friendly. However, their kill counter has the option of being reset, which reactivates their ability to kill. Additionally, Professor Farnsworth and Wernstrom have each designed at least one killbot. New advanced killbots will be returning episode 6 of season 6, having premiered in Bender's Game.
