Flatman

Dr Val Ventura was a mutant who could stretch his body to great lengths. As Flatman, he acted as the deputy leader of the Great Lakes Avengers, an unauthorized division of the regular Avengers superhero group that watched over the Wisconsin area. He was also a scientist, well versed in astrophysics as well as various other fields. While his powers may not have been impressive, his mind was, with the exception of occasionally forgetting which name the team was going by.
