Vision

As the most powerful character in Captain America: Civil War by quite some distance, the Vision is likely to play a rather large part in the story – and he could be the deciding factor in the battle as a whole.

Paul Bettany’s character is made of the nigh-indestructible vibranium and possesses none other than an Infinity Stone (the Mind Stone). His power dwarfs that of the likes of Captain America, and even Iron Man.

As a character who is also self-described as being “pro-life”, he may use his power to bring the battle to an end after coming to realize that it isn’t good for the fate of the world.

And now, on to a character who appears to be very important, if the promotional materials are anything to go by.
