Re: What superhero world concept are you tired of seeing?
As to the Mutant problem. I don't mind the origin, but I make a distinction. If a person dislikes Mutants, they more than likely will also dislike Mutates.
A Mutate is a person who gained their powers thru accidents. Spiderman, FF, She-Hulk, etc. are Mutates. As Mutates are changed, usually on the cellular level, and if the powers are inate, there is no physical difference between a mutant and Mutate, I usually have the haters hate both.
