Wingnut is an alien/mutant bat who, in some incarnations, is partnered with an alien mosquito named Screwloose, and (depending on the version) is a friend or enemy of the Ninja Turtles. In most iterations, he is a spoof of Batman.
So basically this is gonna be sorting fictional characters into groups/teams/associations of any sort they were apart of during their respective canon. Make sure to clarify for teams with multiple incarnations in different media which one you’re talking about.
