The 2016 "Man of Steel" sequel still doesn't have a title, but it looks to have added another superhero: Variety reported Thursday that relative unknown Ray Fisher will play Cyborg in the film, joining a movie that already includes Batman, Superman and Wonder Woman. According to Variety, Warner Bros. provided no comment on the report.

Variety states that Cyborg -- civilian alias Victor Stone -- doesn't have a major role in the Batman/Superman movie, but is planned to have a "much more significant" part to play in future DC Comics-based films "related to the Justice League universe." As one of mainstream comics' most prominent African-American superheroes, Cyborg adds diversity to DC's on-screen roster.

A creation of comic book legends Marv Wolfman and George Perez, Cyborg debuted in 1980's "DC Comics Presents" #26 and was a major part of the duo's storied "New Teen Titans" run. Cyborg has been a part of the "Justice League" cast since the start of the New 52 era of DC Comics in September 2011, and has appeared in Warner Animation's direct-to-home release features "Justice League: Doom," "Justice League: The Flashpoint Paradox" and "Justice League: War."

Fisher is known for his work in theater, having played Muhammad Ali on Broadway last year in "Fetch Clay, Make Man." Previously, he was reported to be in contention for a lead role in "Star Wars: Episode VII." He joins a cast headed by Henry Cavill as Superman and Ben Affleck in his inaugural performance as Batman, plus Gal Gadot as Wonder Woman (the character's live-action feature debut), Jesse Eisenberg as Lex Luthor and Jeremy Irons as Alfred.

Directed by Zack Snyder, the "Man of Steel" sequel is scheduled for release on May 6, 2016 -- the same date as Marvel Studios' third "Captain America" film.
