In the Marvel Universe there are humans, mutates (humans bestowed with powers), gods, aliens, Homo Superior Superiors (evolution's solution to the mutant problem), and mutants.

Are the X-Men an exclusionary group that will only take members who share the same genetic aberration as they do?

  • Was Lockheed an x-man? – Mary ML Mar 13 '15 at 2:47

  • Now I'm confused. Is there a reason you listed Magneto and Storm as examples of non-mutants? – Jack B Nimble Apr 4 '12 at 19:43

    I was going to cite that Topless Robot article I wrote, but @Pureferret did it for me! Awesome! – Brett White Apr 4 '12 at 20:01

    @Pureferret: Even if they lost their powers they still possess the mutant X-gene. I would say they are still technically mutants. – Jack B Nimble Apr 9 '12 at 20:21

    Namor is a mutant. It's been established that not only is he a human/Atlantean hybrid, his human side carries the X-Gene. – Theoriok Nov 29 '13 at 10:43

    To be fair, it's not correct to say that Madelyne Pryor was associated with the team BECAUSE she's a clone of Jean Grey. She originally started dating Scott (or vice-versa), THEN began supporting the team. It wasn't until later that everyone learned she was a clone, at which time she left the team, snapped, and became the villainous Goblyn Queen. – Omegacron Jan 27 '15 at 22:05

Longshot is not a mutant; he is an artificially created humanoid life-form, with the ability to defy probability. (source: http://en.wikipedia.org/wiki/Longshot#Origins)

He was an X-Man in the 1980s during the Outback era.


Ink. Joined in Young X-Men, his mutant tattoo artist imbued him with super-powers through symbolic tattoos. He didn't find out he wasn't a mutant until a few issues into the series.


A couple of additions:

  • Cloak and Dagger - both the result of a drug experiment
  • Danger - the Danger Room turned sentient, Shi'ar technology
  • Deathlok - cyborg
  • Did Cloak and Dagger actually join the X-Men at any time, though? Unless you're counting Norman Osborn's Dark X-Men... – Theoriok Nov 29 '13 at 10:44
  • Danger was never actually an X-Man, just a recurring villain. – Omegacron Jan 27 '15 at 22:07
