Perhaps, but then people are actually answering different questions. I took the question pretty literally: what sort of power should such character have, what sort of feats they should be able to accomplish. And Thor can destroy skyscraper-sized constructs in seconds, lift hundreds of tons and it takes a direct blast from a neutron star to seriously hurt him. Hulk has similar physical power, albeit with less extra shenanigans.
So that's a tad more than I feel a 20th level fighter should be capable of...
