The dialogue is contradictory to Pak's statement, though it really doesn't matter as Amadeus is the one saying it. Pak clearly said that the two burned each other out in the climax of that fight, with the Hulk-Bruce amalgram delivering the deciding blow to Robert in his reduced form. I don't see the logic in calling that a win for the Hulk. If that's true, then by the same token the Gray Hulk's losses should count towards the Hulk simply because they use the same vessel.
Don't get me wrong; I like the Hulk. But it's becoming nonsensical how the fanbase can only see in punches and kicks. Sometimes I think fans look at the dialogue bubbles only after looking at the art. The Hulk has a deep mythos...it's a shame that all some people see is "HULK SMASH!"
