Sooo, I've been thinking on 'powers' for quite a long time, and I finally decided that I wanted to do something a bit different than what I usually go for.

How would you feel about a homeless dude with Shapeshifting powers? By shapeshifting, I mean the shit from Terminator, like his body being made from this liquid steel-like metal that can, along with forming razor-sharp weaponry, allow him to shift into the appearances of others.

To make it non-OP, he won't heal or any of that, of course.
