14 pieces of concept art from 'Captain America: Civil War'

Captain America and Iron Man battle it out.

A great image of Iron Man taking off into the air.

Iron Man's "Civil War" suit is a few steps up from the Mark 43 in "Avengers: Age of Ultron."

Here's the vision for an early look at the film's first villain, Crossbones.

This scene between Crossbones and Captain America hits pause on a pivotal scene from the film's beginning.

This is very similar to some of the first artwork we saw for Black Panther.

Early versions of Black Panther's eyes gave off a bright yellow glow.

We love this image of Black Panther squaring off with Captain America.

Vision lives up to his name.

His love interest, Scarlet Witch, looks far more dangerous in sketches.

Could you have seen Vision in some of these three-piece suits?

Hydra's facility for super soldiers looks a lot creepier here.

Oh hey, Bucky. He's looking good in one piece here.

Not anymore! Here's a cool look at when Tony Stark severs The Winter Soldier's arm in the film's final act.
