His just on another level up than Hulk. Thanos is what would happen if you took Reed Richards and Dr Dooms brains, Dr Strange's magical mastery and Green Scar Hulk's pure strength, combined them together and amped them up a bit.
So how has he been beaten then? I never really followed Thanos, I just saw him own Galatcus once.
