The name Terrorcons refers to several different groups in the Transformers toyline. They are referred to as Terrortrons in Japan.

The Terrorcons are a group of five Decepticon under the command of Galvatron. The Terrorcons transform into nightmarish monster and combine to form the "combiner" Abominus. Their counterparts and rivals are the Technobots. Unlike the other Autobot or Decepticon combiners, Abominus has a time limitation on his combined form as a means of control (as this was only seen when the Terrorcons were working for the Quintessons, this may not be a permanent feature). Abominus is the strongest of the combiners but also one of the slowest and least intelligent (lacking Predaking's agility, Computron's intelligence and Menasor's berserked speed); in fact apart from grunts and growls he has only ever spoken once in the U.S. animated series: "Computron think too much!". His tech spec intelligence rating of 1 is the lowest of any combiner.

The five Terrorcons are:

The Terrorcons would make their first appearance in the Transformers comic in the Headmasters miniseries, working for Scorponok on Nebulos. Issue three opened with them randomly attacking a Nebulon city and being opposed by the Technobots & Autobot Headmasters. They also battled the Autobot Targetmaster in the fourth issue, making them flee when the Autobots realized the damage their battle was doing to a Nebulan city (and the monument they were trying to save).

Abominus has not been a contender in any CBUB matches.
