When I think Hulk, I think ferocious, engine of mass destruction. Enough rage to carry out a massive onslaught of rampaging destruction. When you look at him, you should fear that if he slightly sees you in his peripheral vision, he will annihilate you. What we have now for the default costume is ...well lets face it. He's Gumbi.
Please, if there's still time, put the fear inducing look into hulk.
