Marvel: Camouflage

Katherine Pryde (Shadowcat)
Shadowcat can easily blend into the colors of her immediate surroundings and environments, practically making her invisible to anything seen to the naked eye.

Kurt Wagner (Nightcrawler)
He has limited abilities to blend into shadows, both as a result of his indigo fur and his connection to the light-bending attributes of the dimension through which he teleports. This is also the explanation for why he constantly appears in shadow, even in direct light.

Victor Borkowski (Anole)
Anole possesses the superhuman ability to alter his skin color and appearance, enabling him to copy the pattern of any surface he stands against.
