That's right, IGN fans. Today's Hero Showdown pulls together two of the angriest warriors of them all – Hulk and Kratos. One is a classic Marvel hero who smashes anything and everything in his path (save for box office records). The other is a videogame icon who has made it his unending mission to overthrow the mighty gods of Olympus. When these two heroes roar, anyone with smarts gets the hell out of the way.
