Terrakor

Not even the GoBots fans remember these guys, probably.

The Terrakors are one of two races that live on Skalorr in Xobitor universal streams. Centuries ago, they were a race of primitive and aggressive organics, constantly at war with their neighbors the Protectons. When their war was interrupted by their sun going supernova, they took refuge underground in hibernation. The radiation wound up damaging their original bodies beyond repair, so the Compu-Core transferred some of their essences into robotic bodies.

They are led by the evil, creatively-named Nemesis. Other Terrakors include Nemesis's second-in-command Tyrannix, the dimwitted Goon, the calculating Venturak, and the slippery Steggo.
