Who's the Marvel equivalent to Thawne? Just a character singularly determined to fuck shit up for the hero in the worst way, to fuck with him personally for no reason other than spite? Osborn?
I can see that kind of character going around intentionally trying to break the heroes by doing this kind of beyond the pale (but not REALLY beyond the pale) shit, might be a fun storyline. Kind of like The Gauntlet or Miller DD.
