His first appearance is in the pilot episode of the TV series, portrayed by Richard Ayoade. He then appears in "Mutants", where he steals and mutilates the various animals and keepers of the Zooniverse. He next appears in "Tundra", a remake of the original pilot episode. He inspires Howard and Vince to travel to the Arctic Tundra and find the Egg of Mantumbi, which Bainbridge later finds himself, escaping the Black Frost by using the heat stored in his own moustache. Bainbridge later tries to sell the Zooniverse to build a road over it in "Jungle"; a plan which is later averted by Howard and Vince. Bainbridge finally appears in "Charlie", where he steals credit for Vince's work as a novelist, causing Charlie, the subject of Vince's novels, to appear and attack Bainbridge and his publisher. He was last seen delivering a box to the Nabootique.
