Who wouldn't want to be a shapeshifter?

Or just turn into a mirror image of your surroundings, because you can't just lose yourself?

then you can't move
or maybe you could shapeshift into you but with x-ray vision?

I think you have to shapeshift into something that exists, but if we're saying to hell with the rules that'd be cool

Just chameleon it out, man.

Or just make it look like a crappy cosplay, then shift into an exact replica off stage
