Since when is striking power via punching and strength NOT linked? Thanos and Hulk are very comparable, and Thanos overpowered hulk, hence his striking should be on par with Hulk’s
When striking power is more focused on momentum than your leverage. Shaw can lift a 1000 pounds but he never demonstrated the ability to punch as hard as Bas Rutten.
There is no way to tell if he could replicate the same Leviathan feat which only requires one thing being brute force with no weaknesses involved and the fact Leviathan doesn't share the same human anatomy as Hulk does. He was dodging and striking Hulk in spots where it hurts and its very evident in the fight.
One example in the video shows that he hit Hulk in a spot that hurts due to being close to the neck. Watching the whole video will make you realize that Thanos has no clearcut strength advantage against Hulk at all. This is was all martial arts.
Overpowering is false too because the way he grabbed Hulk by the wrist
Is a very common way to escape a chokehold as seen in this video
So he didn't overpower Hulk through power, he did it through technique.
At least you can make an argument for Thanos being more skilled, but thats about it honestly. I don't see how effective he can pull those off if he is like twice as big as Superman, hence striking at weakspots would be a lot harder.
But if you are still gonna insist that Thanos is stronger than Hulk, I still fail to see how he can put him down unless Superman stands there for hours.
