The CW's Supergirl will borrow again from the Man of Steel's sprawling supporting cast to introduce DC antihero/villain Manchester Black in Season 4.

As announced this evening at Comic-Con International during the Warner Bros. Television presentation in Hall H, David Ajala (Doctor Who, The Dark Knight) has been cast in a recurring role as "the type of guy who brings a knife to a gunfight and still walks away the winner. With a dark past, he easily deflects the brutality of his mission with his charm and sense of humor."

Introduced in 2001 by Joe Kelly and Doug Mahnke in DC's Action Comics #775, Manchester Black was originally the brutal vigilante with a hatred for superheroes who led the team of antiheroes known as The Elite. Their violent tactics brought them, and specifically Black, into conflict with Superman on more than one occasion. A powerful telepath and telekinetic who's able to erase memories, create intricate, large-scale illusions and even give the Man of Steel the equivalent of a stroke, Black ultimately took his own life after his attempts to force Superman to kill made him realize he had turned into a villain.

Manchester Black was reintroduced in 2011, as part of DC's New 52 reboot, and more recently in the Rebirth era, in which he created the illusory Hamilton County, where Clark Kent, Lois Lane and their son Jonathan live. He torment Superboy, and turned him against Superman, but was stopped when his consciousness was transferred to a dairy cow.

The character appears in the 2012 animated movie Superman vs. The Elite, and as an unlockable playable character in the LEGO Batman 3: Beyond Gotham video game.

Starring Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen and Chyler Leigh as Alex Danver, Supergirl returns on a new night, Sunday, Oct. 14, at 8 p.m. ET/PT on The CW.
