Wingnut (Archie)

Wingnut, the clutzy, caped vampire bat, quietly hung out on his home planet Huanu. That is, until Krang destroyed it. Saved and sucked into a vortex before his planet exploded, Wingnut ended up on Earth, along with Screwloose, a levelheaded Huanu mosquito.

Furious and frantic that Krang blew up his planet, the crazed Wingnut's out to get even with Krang - or anyone else associated with the burbling brain. That makes him a perfect ally with the Turtle teens.

Despite Wingnut's bloodshot eyes, defective radar, stunted wings and oversensitive ears, he's determined to be a sewer-superhero. Even with constant training from our green teens, Wingnut's more likely to bump into a building than bust a baddie. Armed with mechanical turbo wings invented by Donatello, Wingnut flutters and putters to put the bite on the Foot Clan.

Wingnut appeared in the Archie Comics first in TMNT Adventures #8, he would later become part of The Mighty Mutanimals. Upon returning from Stump Arena in Dimension X the Teenage Mutant Ninja Turtles encounter a pair of aliens, one was the bat-like Wingnut, the other his partner Screwloose, the two were flying around Manhattan shattering skylights believing that Krang was hiding inside one of the nearby buildings. The TMNT were soon attacked by Wingnut and Screwloose who destroyed the Turtle's blimp. After a short fight the TMNT subdued and tied up the duo, but quickly learned the only reason they attacked them was in belief that the Turtles were working for Krang who had committed genocide on their homeworld, leaving Wingnut and Screwloose the last of their species respectively, at this point they were abducted by Cudley the Cowlick who explained to the TMNT that he was going to take them to compete on Stump Asteroid. The TMNT later reunited with the duo of Wingnut & Screwloose, when the Turtles, Cherubae, and the Intergalactic Wrestling Federation joined forces against the Foot Clan and Maligna, at first it seemed Wingnut would be of little help, and that he was completely uninterested in joining the fight against the Malignoids, especially after he and Screwloose flew away from the battle completely, but in fact it turned out Wingnut's super hearing detected the voice of Krang, and he attacked Krang, Shredder, Bebop, and Rocksteady, preventing the Foot Clan from obtaining the Turnstone.

Wingnut made a cameo appearance in Tales of the TMNT Volume 2 Issue #58.

Behind the Scenes
Wingnut's first appearance was actually as a villain and ally of Shredder in a mini-comic that came with Ralston-Purina's Teenage Mutant Ninja Turtles cereal.

The emblem on his chest looks like the Batmans logo.
