Also, just a side note from a comic book geek, most if not all of the Avengers are either non-mutant or an alien. The main characters that originated the Avengers are Thor (from Asgard), Iron Man is really nothing more than the equivalent to Batman (Tony Stark = Bruce Wayne, both rich and just normal men), Captain America again just a normal man on the juice, and the Hulk the product of a gamma ray radiation experiment gone awry.

I mean the list of Avengers is very long, even Spider-Man at one point joined the Avengers.

But my point to this is that for the most part the Avengers are non-mutant Superheros...
