Questor
From Tardis Wiki, the free Doctor Who reference
Questor was a villain who bumped into the First Doctor, Dodo and Steven, in the living jungle of Tropicalus. The Doctor and he engaged in a battle of wits and Questor was defeated.
Some time later, Questor joined forces with other aliens to try to kill the Doctor, their common enemy. He was shot in the face by Bolog, who believed him the Doctor in disguise. (DWM: Death to the Doctor!)
