A new piece of "Captain America: Civil War" concept art from artist Andy Park reveals a major shift in allegiance for one member of Team Cap: Ant-Man. In the piece, Captain America goes head-to-shield with Ant-Man during the infamous airport scene, where both Cap and Iron Man's teams clashed in a big way.

In the film, Ant-Man -- who levels up to Giant-Man in this sequence -- is solidly on Team Cap; Falcon recruits him onto Cap's side, and he fights Team Iron Man until his arrest. In fact, he used his enlargement ability in order to distract Team Iron Man from realizing that Cap and Bucky were on their way to steal the Quinjet. However, Park's concept art reveals that Ant-Man's role was almost very different -- unless, of course, there's more here than meets the eye.
