Terrorcon (Transformers)

Terrorcons are a subspecies of monstrous reptilian Cybertronians from the planet Cybertron.

Biology
While also being a subgroup of Decepticons, Terrorcons consider themselves a species unto themselves.

Anatomy
Terrorcons share a similar biology to other Cybertronians, except they transform into monstrous robotic reptiles.

Powers and abilities
Terrorcons share many of the same abilities as other Cybertronians.

Select Terrorcons can combine to form a combiner known as Abominus.

Culture and society
It is hard to take the Terrorcons seriously as they have a bunch of personality problems and a lack of decency. In short, they are all positively insane, even by Decepticons standards. Nevertheless, they are generally considered to be the mortal enemies of the Technobots.

Individually, Terrorcons are not much of a problem when taken on one-on-one and can easily be outsmarted. But when they are together as a group, they become very dangerous for bunch of reasons that range between following orders, fighting for sport, attempting to alleviate boredom, and even because they are performing a dare.

Terrorcons are not what one could call soldiers, warriors, or even brawlers. Rather, they are animals who bring that thought pattern to everything they do, including their choice of monstrous robotic reptiles for alternate modes.

Terrorcons are not known for being particularly loyal, as they would occasionally ditch the Decepticon cause in favor of working alongside the Quintessons.
