The theatre actor, who has appeared in the TV series 'Orange Is the New Black' and 'The Big C', will join Henry Cavill, Ben Affleck, Jesse Eisenberg, Gal Gadot and Amy Adams in the cast for the untitled film, reported Variety.
Cyborg, otherwise known as Victor Stone, is a member of the Justice League. The character will become a prominent figure as Warner Bros and DC develop more films within the Justice League Universe.
Cavill previously revealed that he would be keen to see Cyborg and STAR Labs featured in the sequel.
The 'Batman vs Superman' film will mark the first time the two superheroes appear together in a live-action movie.
Zack Snyder is directing the movie, which will be released in UK cinemas on April 30, 2016 in the UK and May 6, 2016 in the US.
