Tachyon's Empire (formerly)
Likely medium sized.
Terraklon VI was a planet and the homeworld of the Terraklon species, including the Terraklon gladiators and Umbüko gladiators, the latter of whom Captain Qwark claimed to have trained with. It was mentioned by the Tachyon Robot in Zordoom Prison, having been consumed by the Thyrullian supernova. Due to this, the sentences of the Terraklons were commuted and they were free to wander the galaxy in search of a new place to live. All except for Flint Vorselon were freed, as the cyborg was serving a lifelong sentence, although he later escaped.
