Captain America vs. Iron Man

It shouldn't surprise you to find this fight on this list "“ it is the moment toward which the entire Civil War has led. And the fight once again shows why Captain America's hand to hand skills cannot be outmatched, even if you have an AI who can analyze all of his moves. Iron Man learned this the hard way.

And this is also the most emotional fight scene in the entire MCU. Two friends are fighting one another. Tony Stark finally finds out who killed his parents and who knew from the beginning. Steve Rogers has to defend his friend, who was brainwashed at that time.

The scene left me speechless. And it could have been the best in the entire flick (if it weren't for that chase). However, it still tops everything in the MCU, if we take into account the emotions it conveys.
