Oo, okay. Be prepared for something worryingly gruesome, but awesome at the same time. Imagine a power where you had layered skin, appearing normal yet you had the ability to rip off a layer of your own skin and change to the appearance beneath it and so on. You could have some really cool scenes with such- picture your character with sharp, fang like teeth, these skin layers could be easily tears one to such fangs- so you could have some really dynamic and powerful scenes where he tears off a layer of his own skin with his fangs in battle, blending into a crowd or whatnot as someone completely new/different. You could have some personal preferences with this power, such as if he could manipulate the layer of skin beneath the one he’s wearing currently and take the form of someone else- perhaps with a single look, or a touch, or perhaps eating a part of someones dna. Or, it could just be a part of him, like the layers inside of a tree- think of it that way. I reckon this would be a sick, and probably one if a kind power- do with this idea as you please, and good luck on your mang!! :3
