I didn't read the comic Pride mentions, here, but I think many viewers are overlooking the rock-paper-scissors dimension of the MCU that is always at play.
For example, in the forest of Sokovia, where he destroys Ultron, what does he use? He focuses the power of the mind stone. Ultron is a computer. The rest of the Avengers struggled greatly against Ultron, obviously, but being the synergy of pure synthetic algorithm, what defense did Ultron have against Vision and the Mind Stone? Vision literally unraveled him in a moment; because that's all Ultron was. He had no flesh, no conscience, no soul. It was like The Matrix. We were little more than a virus to him, but ironically, he was little more than a virus himself to Vision, so destroying him was little different than zapping a computer virus. He may have been overwhelmingly powerful, but he was also overwhelmingly one-dimensional.
Thanos suffers no such weakness.
Yes, he does.
He jumps off a bridge and lands over three stories below on the top of a car like he was hopping off a curb. A normal human being cannot sustain a fall like that. Remember the first time Cap throws his shield at him not knowing it's Bucky after chasing him across the rooftops following Bucky's assassination attempt on Fury? That shield throw would have cut the normal human in half. That's like catching a bullet the size of a sled. Your arm doesn't absorb that force. He throws the shield himself so hard at Cap at one point that when it misses it lodges itself halfway into a nearby Van. He knocks Captain America around. He clearly has super strength. He also has super durability. He takes shots from Captain America that would kill the normal man (ex. running knee to the chest into that van).
Where in the hell do you get these ideas? They make his extraordinary strength and durability so obvious.
