Marvel officially settles whether Iron Man could ever defeat the Hulk, and the verdict can't possibly be more definitive. While iconic, the Avengers' core line-up is quite unbalanced, with a peak-human Super Soldier and a genius in a metal suit fighting shoulder to shoulder with a literal Norse god and an unstoppable gamma monster. Thankfully for the people of Earth in the Marvel Universe, these four heroes and a few dozen other superhumans work together to protect the world instead of constantly fighting each other to the death to conquer it.
