The Mutant Workers were concerned about Governor Kolp's 'radioactive hell'-induced irritation, just moments before he discovered there were intruders in their city. The Mutants were completely armed and were loaded onto a school bus, a first jeep with a cannon, a second jeep with a long machine gun, a motor vechicle, a military truck, and 3 motorcycles after Caesar, MacDonald and Virgil sneaked into the city (they believed that the intruders were sent to terminate them). One of the motorcyclists was killed by Aldo's sentries, but Kolp ordered his jeep cannon shooter to kill the two sentries. One sentry was dead, but another sentry was injured and went back to the city to warn its residents. The Mutants radioed Sergeant York and were getting ready to invade the city by morning. Their fates are unknown, they were either captured by Caesar's apes or were killed, like Kolp, by Aldo's gorilla cavalry, although Sergeant York survived the entire battlefield and went back to the Mutant's hideout.
