Q: Mystique

Why is Mystique blue ?

Because some mutant look different when they become mutants.

Why is Nightcrawler blue? Because Mystique is his mother.

@themanintheshoe: @teerack: lol i get that but how did she get her blue skin

@innovated: The only reasonable explanation is that her mutant genes make her blue, without any reasonable explanation. The X-gene is whacky.

How did you get whatever color skin you have? She was born with it/got it when her mutation activated. No big story or dark origin for it: She just has it.

I don't think there's ever been an explanation... I think it's just blue becuase that's the color of her skin.

I could be wrong, though.

When she became a mutant.... when she was born.....

Also; Welcome to Comic Vine!

Or innovated is just playing us and the real question is why Dave Cockrum and Chris Claremont chose to make her blue!

Genetic something .......

From what I gather the melanin in her mutation was blue so that's what she became...Blue. That's also where she gets her power. So its a mixture of the melanin and cells that make her shape shift. So quite literally that melanin change gives her power...one unfortunate side effect is that she is Blue.
