Even the Batman cartoon universe has this trope. Not long after she got back, she'd lose her Marvel super hero sex in a battle in the skies between Petey and Norman Osborn, his nemesis, the Green Goblin. But of the woman he's been with, the one who is his best match, is the villainous Mystique. Except when these magnets touch, they do sex stuff. Heroes and villains have been Marvel super hero sex each other since the first comic book shot its way across the sheets, spewing its inky print and staining that pure whiteness with colors and marvelous magic. There's no shame in being one of the third-string X-Men.
