My son got this shirt. It has six comics character's symbols on it; five of which I can identify:
Spider-Man Captain America Iron Man Thor (???) Hulk
Wolverine seems like he'd fit the bill; that would pretty much round out Marvel's top 6 heroes, although he's not quite as Avengers-related as the other five. But, Wolverine is more of a yellow and black kind of guy, and I've never seen a symbol like that.
Whom does the 'W' symbol represent?
