Insect Mutant is a man named Frank, holding up a large fly-like Alien which protrudes through his stomach. On the back of Frank's overalls is the text "Frank's Motors", and his human face is also mutated, somewhat like that of the Priest Mutant. The Alien's head is classified as the character's head, and firing at Frank's head does not count towards a headshot. They appear in the original TimeSplitters, and then reappear for TimeSplitters 2 as a classic character, however, they have failed to make a third appearance (similar to Impersonator).

The Insect Mutant reappears in TimeSplitters 2, becoming one of the few Classic characters to have returned from the first game. Though he returned, there was no effort to include him in anything but Bot Sets in the game. There he is associated with the other Classic characters and the Chinese Restaurant, despite having never appeared in its story. Unlike in TS1, his head is not detachable.
- Main article: Village (Story)
In a Village in the 1950s, a cursed artifact was discovered, which heavily mutated the inhabitants. It is the mission of two scientists, Doctor Seth Graven and Doctor Katje Nadir to return this artifact for deeper research, however the Mutants seem to be against this, whether of their own choice or via mind control; only death will stop them from trying to preserve it, hidden beneath the Village.
