When he was ready for them, he dominated Thor and the Hulk pretty easily individually. The way he took hammer hits and hulks punches puts him physically near kurse level.

He was winning against Hulk before Thor blindsided him. Using hammer shots to the knee and alot of energy attacks.

The Hulk koing him was clearly another example of the hulk not have dynamic strength. But the amount of dynamic strength he didn't show would depend on if this Thor had some Odin power.

I'd rank Rulk form low end: Thanos strength to high end: kurse with brains.
