I wonder why superheroes have capes. If the hero flies, what is the function? It would seem to add drag to their flight. Their skintight suits would seem to already be aerodynamic. I thought maybe it was a film effect to show the cape flapping in the breeze to indicate flight, but many of the superheroes existed in print first. Maybe it was just an art/costume decision to add contrasting colors and balance out the suits? That would make sense whether they fly or not. If I were a bigger superhero fan I’m sure I would know just where these kind of internet fights take place.
