A super-powerful punch
Thanos proved that he’s one of the most powerful characters in the Marvel universe if not the most powerful. And he wants the world to know it. Dr. Strange put up a pretty good fight against Thanos. However, he had the taste smacked out of his mouth for his efforts.
In Avengers: Infinity War, Thanos uses Dr. Strange as a personal punching bag and knocks the soul right out of him. As soon as this massive punch lands, you can see Dr. Strange’s astral projection leaving his physical body. Now that’s a punch that even leaves Mike Tyson in awe.
