I think Shocker's clothes are his costume, since he always wears them when he's on a crime spree. I noticed that his jacket's a little thick, and I suspect that the quilt is underneath his jacket.
I fully agree with Electro's costume, thank God they totally revamped it in UU. The lightning-like scars on his face is cool.
I also don't like Ultimate Punisher's costume, but it's actually practical. His bulletproof vest has the huge skull symbol so the tendency of criminals will to be shooting at it, which Frank would probably want to happen. I agree still that they should have used his look in the movie or the MAX version.
Don't like Elektra's new costume in Warriors. Unless its purpose to make people gawk more at her cleavage and legs, it doesn't make a lot of sense. They should have stuck with the Larocca version or the black costume she was wearing before.
Green Goblin shouldn't have look like the Hulk. I think his best look was his first appearance in Legacy. He looks entirely like a Goblin, but he's not gargantuan. That would easily differentiate him from the Hulk. The fact that he was wearing ripped purple pants in the USM game did not help at all in differentiating him from Hulk.
