Captain America, Falcon, Black Widow and Hawkeye will form an allegiance against Iron Man, War Machine, The Vision and Ant-Man while Black Panther and Scarlet Witch are 'somewhere in the mix', reported Ace Showbiz.

The main villains of the 2016 sequel are said to be Baron Zemo and Crossbones. As for their costumes, Crossbones is described as 'messier' as it will be his trademark look from the comics with the skull imagery on the suit described as 'graffiti-esque'.

He will also "wear the skull mask that covers his entire face, which is said to be a hybrid mask/helmet."

Captain America will have a 'slightly modified suit' from his 'Avengers: Age of Ultron' suit, the Winter Soldier will look "very much as he did before, long hair and all," while Falcon's suit will be upgraded with red and grey colours.

For the plot, Ant-Man will 'take on Giant-Man form in the battle.'

Starring Chris Evans, Robert Downey Jr, Scarlett Johansson, Chadwick Boseman, Anthony Mackie, Jeremy Renner and Frank Grillo, 'Captain America: Civil War' is set to hit theatres in the US on May 6, 2016.
