Corporal Capeman, voiced by Townsend Coleman, is a recurring character introduced in the second season as Inspector Gadget’s sidekick. Capeman is a self-proclaimed superhero who acts in the manner of a stereotypical crime fighter, but he is equally as inept as Inspector Gadget, if not moreso. Capeman is obsessed with learning to fly and often mistakenly believes he has miraculously acquired the power of flight while in the midst of dire circumstances.
For some reason, Penny nicknames Capeman "Capey". A running gag has Gadget mispronounce Capeman's name as "Capman". Corporal Capeman has a mutual dislike for Brain(Brain hates Capeman for mistreating him, and Capeman's hostility towards Brain may stem from the dog kicking him for no reason during their first meeting).
Capeman first met Inspector Gadget when the bionic detective was assigned to thwart an attempt by M.A.D. to steal gold. Capeman accidentally helps Gadget arrest the M.A.D. agents, but the agent in charge escapes. Dr. Claw later scolds The Ninja for not getting rid of Gadget. The Ninja goes to terminate Gadget in his sleep, only to be beaten by the gadgets in the Gadget House.
Corporal Capeman is not well-liked among the Inspector Gadget fandom.
