Dominic Purcell has boarded The CW comic-book drama as a DC Comics villain, reuniting with his Prison Break co-star Wentworth Miller in the 10th episode, The Hollywood Reporter has learned. This marks the first time Purcell and Miller, who played brothers Lincoln Burrows and Michael Scofield, will have appeared together since Prison Break ended in 2009.
Purcell will play Mick Rory, a pyromaniac who finds an outlet for his obsession with fire when he teams up with Leonard Snart/Captain Cold (Miller) and becomes the villain known as Heatwave. Miller was cast in The Flash back in July and makes his debut in episode four. Purcell's character will also be heard from in that same episode.
