The idea comes out because Axe and Hellboy have same skin color.

I think it is cool and the ingame effect is also great. Many friends tell me about the copyright problem and I very appreciate them. I do this just for fun. If Valve will add it into the store, I think Valve will seek the opinion from Marvel, and maybe for Marvel it is good thing too. Will give the Marvel character goes for promotional too. I hope it is the Win-win result.
