It’s pretty much common knowledge that Batman defeated Superman in single, melee combat in Alan Moore’s The Dark Knight Returns comic series.
However, looking back, I don’t know if I would qualify it as a “real” victory anymore. Batman had the upper hand for a few seconds, and then had a heart attack. Without the heart attack, I think Superman would have easily won a slightly longer fight. Also, Superman was holding back. He could have easily fried Batman within the suit using his heat vision. If Superman wasn’t trying to protect Batman, he could have ended the fight without even bothering to let Batman get close enough to touch him.
Nowadays, however, that one “win” crops up in every single discussion about Batman’s badassery, as though that one victory (with a ton of cheating) somehow legitimized Batman’s strength.
So, my question is: do you think the “win” was temporary or absolute? Looking back, it’s like somebody snuck up behind you, pulled down your pants, then ran into the girl’s bathroom so you couldn’t follow.
