I've got a backlog of matches that would be fun, but there won't be a chance to do. I thought others might have the same.
I've thought about doing Prometihius vs. Taskmaster a few times. The characters have similar powers and it'd be interesting to see.
I've also thought about doing a dog-fight with Bronx (from Gargoyles) vs one of the Vinz Clortho from Ghostbusters. I wouldn't be surprised if the GB Terror dogs were at least a partial inspiration for Bronx's appearance.
Maybe Bronx could have teamed with Lockjaw against both Terror Dogs.
