Great Lakes Region
A list of Marvel characters who originated from the Great Lakes states or served on the GLA. Not including Pennsylvania or New York - they have enough coverage.
States included are Minnesota, Wisconsin, Michigan, Ohio, Indiana, Illinois, and Iowa.
If this list is any indication, the GLA should probably move to Chicago, Illinois to be more effective.
As always with most of my lists, these are living characters. As they die, they'll be removed. As more from the area are introduced, they'll be added.
