Casting for CW's The Flash continues to plumb the depths of Firestorm characters! On next week's episode of The Flash, we'll see Firestorm foe Eddie Slick (a.k.a. Sand Demon) portrayed by Kett Turton! Talk about obscure! Eddie Slick first appeared back in Fury of Firestorm #51 & #52 (1986). When he was first introduced, Eddie was a corrupt boxing manager. He had no super powers, but was a surprising look-a-like for Professor Martin Stein. When Eddie reappeared in Firestorm the Nuclear Man #74 & #75 (1988), he'd been buried alive in the desert by his gangster "friends". Through a series of unique events, Eddie survived and was transformed into a creature entirely composed of sand, able to control other sand at will. He called himself "Sand Demon" and went on a rampage across Las Vegas. From the next week's previews, it appears the TV version of Eddie Slick has similar powers.
