Skin
Angelo Espinosa, also known as Skin, is a mutant with the ability to stretch his skin like rubber. Skin was a member of the younger generation of X-Men, who were recruited by Charles Xavier after the original team had disbanded.

Skin proved to be a valuable member of the team at times by using his powers to both defend his fellow mutants. His sense of humor and laid-back personality made him a fan favorite, yet his powers were more creepy than actually useful.
