Clancy Brown, who starred in Fox's Sleepy Hollow last season, has signed on for a major recurring role in CW's The Flash as General Wade Elling, debuting in the show's fifth episode. It isn't known exactly how many episodes he will appear in during Season 1.

Last week, we reported that Kelly Frye has signed on to play Sgt. Bette Sans Souci, a.k.a. Plastique, a bomb disposal expert who was given the ability to turn anything she touches into a bomb, due to exposure from the same S.T.A.R. Labs incident that turned Barry Allen (Grant Gustin) into the World's Fastest Man. That report also indicated that, unlike her villainous origins in the comics, Plastique will become an ally to Barry, as she tries to evade government forces.

Clancy Brown's General Wade Elling is the head of a black ops team who is hunting down Plastique to turn her into a human weapon. Elling is described as tall and imposing, with, "a face carved from years of duty," who will do anything to protect American interests around the world. He also may have ties to another central character on the show.

In the comics, Elling debuted in the first issue of Captain Atom in 1987, who is tied to the origins of that character along with Major Force. He also has connections to the Justice League and Amanda Waller's Suicide Squad.

Clancy Brown joins a growing list of guest stars and recurring characters such as Captain Cold (Wentworth Miller), Firestorm (Robbie Amell) and The Clock King (Robert Knepper). We also reported earlier this week that Tony Woodward a.k.a. Girder will be a recurring villain throughout the first season, although he has not been cast yet.
