Cyborg will appear in “The Flash,” sources tell Variety.

It’s not known how substantial a role the hero will play in the film. But it’s another signal of DC Comics and Warner Bros.’ ambitions to build a sprawling, cinematic universe to compete with Marvel Studios, one where heroes and villains will pop up in solo spinoff adventures, as well as lend support to other costumed allies. Cyborg’s appearance in “The Flash” and next year’s “Justice League” are intended to whet audiences’ interest in the character, building toward a potential, standalone “Cyborg” film in 2020.

Ray Fisher, a newcomer best known for his stage work, has played Cyborg and his alter-ego Victor Stone. He made a small cameo appearance in last spring’s “Batman v Superman: Dawn of Justice.” DC released “Suicide Squad” this summer and will debut a “Justice League” film and “Wonder Woman” in 2017.

A spokesman for Warner Bros. declined to comment.

For readers not weaned on comic-book lore, Cyborg is transformed in a science experiment into a half-man, half-machine hero. His metallic prosthetic limbs give him super strength and other enhanced abilities.

“The Flash” stars Ezra Miller as the title character and is directed by Rick Famuyiwa, who made a stir with the Sundance Film Festival breakout, “Dope.” The film will begin shooting this year in London, and is expected to open in 2018.
