Captain America

Well, Civil War is his movie and he is the greatest soldier of all time (in the MCU, at least). So it was obvious that Captain America was going to rank among the top three.

He is, actually, the first true superhero on this list, being at the peak of human condition and possessing a strong sense of morality. And that is why he deserves to win any fight – and he would, in the MCU, against any of the previous mentioned characters.

In close quarters he can match anybody. At a distance his Frisbee is unmatched. But not even he can get close to the last two on this list.
