He has undergone a scientific experiment which mutated his cells, he's permanently invisible. He remains very solid until he chooses to go desolid. I don't really want him to be a stretch guy and I'm not wanting to pile on other powers. Just looking for tricks. I spent 20 points on his martial arts and I'm thinking of giving him a blade and maybe a crossbow. I'm also thinking of giving him a backstab ability perhaps with the Find Weakness talent. I want kind of simple, old school character.
Thoughts?
