History
The wicked Brancheerian Monty Punnions noticed that Giant Silver Ants were going to invade Earth, but convinced them to instead invade the Brancheerian homeplanet Sirus. Monty left a trail of replicas of Earth landmarks across the universe to lead the Ants to Sirus: (COMIC: The Tail of Decky Flamboon) a replica Eiffel Tower to imprison Cobalikbot Acorn Delta on Cobaltikar 45, (COMIC: Tower of Power) a replica Taj Mahal to help the Propheetis of the Hollow Moon of Artenture invade Earth, (COMIC: Terror in the Taj Mahal) and a replica Colosseum to Professor Rulas on Phwillite. (COMIC: Colossus of the Colosseum) By the time the Ants arrived on Sirus, the planet was empty and the Brancheerians had escaped to the Moons of Flamboon. (COMIC: The Tail of Decky Flamboon)

During the Last Great Time War, the Daleks laid waste to a Brancheerian colony on Donnahee's Moon, taking prisoners. A Brancheerian from the colony worked for the Daleks to protect their people, and was later captured by Veklin and Susan on Florana. (AUDIO: The Uncertain Shore)
