The Mighty Heroes was a fairly wacky `60s animated series created by the boundary-pushing animator Ralph Bakshi for Terrytoons, otherwise probably best known for Mighty Mouse. The Mighty Heroes featured the bumbling crime fighting stylings of Rope Man, Strong Man, Diaper Man, Tornado Man and, uh, Cuckoo Man. We personally think Cuckoo Man got the shaft pretty hard with regards to super identities.

The Mighty Heroes "The Monsterizer"

"The Junker"

"The Frog"

Interesting bit of trivia: evidently in an episode of Mighty Mouse: The New Adventures, the Mighty Heroes retired from fighting crime badly and became bad lawyers with a firm called Man, Man, Man, Man & Man. (Via wikipedia)
