In 1989, Midge was transported from Earth to the Cheetah World by a Kitling, where he had to survive along with others who had teleported there. While being coerced by the survival trainer Paterson, he became infected with the Cheetah Virus. The Master, having been trapped on the Cheetah World, used him to teleport to Earth. The Master then instructed Midge to engage the Seventh Doctor in a duel on his chosen transport, a motorcycle. The collision caused a large explosion, injuring him, but the Doctor survived. The Master, using "survival of the fittest" as his reasoning, instructed Midge to end his own life for his failure, which he subsequently did. (TV: Survival)
