Here's Wingnut and Screwloose of vintage Teenage Mutant Ninja Turtles fame. They were also part of the Mighty Mutanimals. I guess he showed up in the old TMNT cartoon but I never saw it. It may have been a later episode.

This version is based off of the 1990 action figures. I made Screwloose pinkish instead of purple or yellow.

It's weird, but it only dawned on me today after I'd had this pic drawn for a few days & owned the figures since 1990, that Wingnut is a spoof of Batman. Should've been obvious but I got tripped up by his wings all these years.

For some reason, I always thought Wingnut was an alien bat guy with gimpy wings and Screwloose helped him build his mechanical wings so he could fly like the proverbial bird.. or bat... or butterfly. Dunno how true that is. TMNT history is all over the map.
