After a long day of fighting crime in the big city even superheros need to use the bathroom (except Aquaman of course, he just goes right in the water). And when they do, they use Superhero Toilet Paper, natch. Soft enough for Wonder Woman but strong enough for Thor. You might want to pick up an extra few rolls if you turn into a massive beast that devours everything in sight when he gets angry. I’m looking at you Bruce Banner.
