Stacy X

Stacy X (http://en.wikipedia.org/wiki/Stacy_X) is probably most famous for having worked as a mutant 'prostitute' before joining the X-Men. Technically there was no touching, but I guess using your tactile mutant pheromone powers to get someone off is the same thing. Hated by a good deal of fans (not me!) her last official scene as one of the X-Men was skipping rope naked on a VHS tape. The only thing to be embarrassed about there is that she was still recording to VHS.

Getting The Look
Stacy X wore a very simple, and very revealing costume. The main part of her aesthetic is her mutant snakeskin. A striking look that few artists took the time or effort to get right (if you're interested read Uncanny X-Men #399. The art, and Stacy's introduction are both great).

Mystique

Mystique (http://en.wikipedia.org/wiki/Mystique_%28comics%29) is a longtime enemy of the X-Men with the power to duplicate the exact appearance, mannerisms and voice of another person. I can't make jokes about Mystique, because Mystique is awesome.

Getting The Look
I've wanted to make a Mystique toon for years, but there was never a piece that came close to her signature flowing dress until the release of the Amazon Fury Part II DLC with its Circe inspired styles. Fittingly, your character will need to be a villain to make this look work as two of the style pieces are only accessible on the villain side.

Dani Moonstar - Moonstar

Dani Moonstar (http://en.wikipedia.org/wiki/Danielle_Moonstar) is a Native American and one of the original New Mutants, kind of a teenage class of replacement X-Men from the 80's. She originally had the power to project three dimensional images of a person's greatest fear, later learning how to generate arrows comprised of this psychic energy. For a while she wore a mask and masqueraded as a villain, confusing her friends despite the fact she was using her own last name as a codename... So I guess they're just not very bright.

Getting The Look
This is one of those costumes where the details changed frequently, almost in every issue, but I think this version captures the elements that stayed consistent. It's especially close to the later, more refined look that Moonstar donned.
