Have you noticed Superheros are not the creative people when it comes to disguises? Superman and Wonder Women took off their glasses, Batman and Robin wore a mask, and other Superheroes just put a stocking cap over their head. Their physical appearances did not change nor did their voice, but nobody could figure out who they were. All they needed was a crazy costume and nobody, not even the evil genius, knew who that masked person was.
So don’t be surprised if Spiderman shows up to your Halloween Party dress like a pumpkin.
