“Who’s tougher: Superman or the Hulk?” remains the playground question of the ages, right alongside “Who’s stronger: my dad or your dad?” Of course, in comic books (and now, comic book movies), superhero toughness is measured in different ways.

The aforementioned Superman and Hulk literally have invulnerable skin, where someone like Wolverine gives the appearance of being invulnerable due to his healing factor and metal skeleton. Then there are heroes like Iceman and Colossus, who create external skins for themselves that act as a kind of armor, but underneath all that get paper cuts just like the rest of us.

Thankfully, all of us superhero devotees now have this handy infographic chart, created by McDermatology.com, to show the differences in the tough hides of almost every major superhero. Called “The Super Skin of Superheroes: 86 Powerful Dermises of America’s Comic Book Heroes and Heroines,” this chart shows us the different ways characters from DC Comics, Marvel, Image and more are able to get beat up over and over again and pretty much never show a scratch.

There are some curious inclusions and omissions on this chart, however. For example, there are a ton of minor X-Men characters that you’ve probably never heard of, and yet there are no Green Lanterns on the list. Surely a Lantern’s ring-created external force field counts as a second skin as much as Iceman’s ice skin, right? And I’ve been reading Marvel Comics my whole life, and even I had to look up who the heck Machine Teen even was. Nevertheless, this is a fun and well made little chart that is pretty darn accurate.

You can check out the full infographic down below (Be sure to open the image in a new tab to see it in full size).
