The Terrorcons were a Decepticon gestalt team of robotic monsters, counterparts to the Autobot Technobots. There were five team members: Cutthroat, Sinnertwin, Blot, Rippersnapper, and the leader Hun-grrr. They combined together to form the super-robot Abominus.
The Terrorcons didn't get much time in the cartoon, mainly due to their collective lack of intelligence. They first appeared without origin in the episode "Grimlock's New Brain" and again in "Money is Everything" and "Call of the Primitives" after it.
