Oblivioner

Oblivioners were a race of human-animal hybrids who were genetically manipulated so that each appeared unique. They originated from the planet Oblivion in the Arcan system.

They were originally humanoid until the ruling families unleashed a plague onto their enemies which intended stripped all of the victim's minds bare, but instead transformed its victims into hive-minded living generators of psychic energy. These new beings turned the tables on the royal family by transforming them into hybrids of animal and humans to be used for their entertainment. (DWM: Oblivion)

An Oblivioner named became a companion to the Eighth Doctor.
