@20damon: Thor didn't have the upper hand against Thanos. It was literally back and forth. WM Thor has no feats compared to the Thor Thanos fought. So Hulk holding down WM Thor doesn't mean much. In Infinity Thanos was using brute force. Not tech or intelligence. He was simply beating ass. He casually repelled a rampaging Hulk. I know it didn't hurt Hulk but Thanos wasn't trying. Hulk has not shown he can hurt Thanos either. Still, In a purely physical fight, I agree hulk wins after a very very long fight.
@kute: The OP says the planet is indestructible.
@stl9997: Groot was never knocking Thanos around.
