Andy Mientus, star of the short-lived NBC show Smash, will join the cast of The Flash as Hartley Rathaway/Pied Piper.
The hearing impaired and openly gay villain is one of DC’s original Rogues, "Hartley is a bona fide genius who used to work at S.T.A.R. Labs until a falling out with his mentor, Harrison Wells (Tom Cavanagh). The particle accelerator robbed Hartley of his hearing, but inspired him to create a series of sonic weapons that he uses in an effort to punish Wells by destroying his new protege: The Flash."
The Pied Piper will make his first appearance on The Flash in the 11th and 12th episode of the show's first season.
The Flash airs Tuesdays on The CW.
