So, if Ben “The Thing” Grimm were to fight Medusa, would he have to avoid seeing her? I mean, what’s the worst that could happen, he’d be turned into even more stone? I feel like there’s probably an implicit answer in that The Thing is still around in comics, I think, and surely the Fantastic Four battled Medusa at some time in the 60s because if it was the 60s and you were a superhero you just did that sort of thing, battling ancient Greek mythological figures, possibly in space. So The Thing is still around, and you don’t see Medusa’s face slapped all over comic books, but that’s surely just because she’s waiting to be rebooted into a new movie series of her own, right? And that means he probably handled things just fine.
Anyway, I feel like there’s probably someone well-versed in the details of the Marvel comic books universe who could tell me with certainty about their fight and whether he had to do anything special, but, I dunno. I feel vaguely bad when I can effortlessly explain subtler points of 1980s G.I.Joe episodes to people, and I don’t want to make the Marvel comics expert have to feel like that too.
