Back in the early 90s, John Byrne did a run on West Coast Avengers (Avengers West Coast?) that I absolutely loved, and part of his run was the introduction of The Great Lakes Avengers, a ridiculous team of Midwestern Superheroes who actually turned out to be pretty competent and powerful. Hawkeye and Mockingbird both left The Avengers to lend guidance to the GLA. They popped up maybe a couple other times, but were subsequently ignored for the most part.
In the mid-2000s, Dan Slott brought the team back for a mini-series and some one-shots that I enjoyed. They were goofy fun heroes, and sadly, I don’t think Marvel or DC has any room for that type of book anymore.
Anyway, the team consisted of Mr. Immortal, Doorman, Dinah Saur, Big Bertha and Flatman (pictured).
