He-Man vs. Superman
Since He-Man is "the most powerful man in the universe", I would assume that he could beat Superman, whose powers only come about through exposure to a yellow Sun. I know this has been debated a lot online over the years & that these two fictional characters actually met in a comic book setting in the 1980s where they basically fought to a standstill.
I've been watching re-runs of this 1980s TV show late nite on the ME TV network recently, and I've been noticing some odd humor that I never picked up on as a kid. In the recently-aired episode, "Daimar the Demon", after He-Man tries to snag Daimar with a bolas & fails when Daimar easily breaks it, he turns to the camera & says, "Anybody want to buy a used bolas?"
