‘The Flash’ Adds Victor Garber, DC’s Pied Piper, First Firestorm Photos

Yesterday morning 'The Flash' sped out some exceptionally spoilery photos of the DC hero facing his greatest nemesis, but the series was far from finished flashing its latest wares. Not only has the 'Arrow' spinoff added veteran actor Victor Garber in a familiar DC role to compliment some new Firestorm photos, but so too will 'Smash' star Andy Mientus portray openly-gay DC villain "Pied Piper" in upcoming episodes.

The Hollywood Reporter broke the story that Garber would appear beginning with the twelfth episode as Dr. Martin Stein, a brilliant but arrogant nuclear physicist specializing in transmutation. The explosion of the S.T.A.R. Labs particle accelerator ends up fusing him with the younger, more impulsive Ronnie Raymond ('Arrow' star Stephen Amell's cousin Robbie Amell), leading Stein to search for a way to separate the two before it becomes too late.

The fusion of both characters traditionally make up the DC superhero Firestorm, while Amell will first appear in October 21 episode "Things You Can't Outrun," the first photos of which you can find below. There, we'll see the role that maintenance worker Raymond played in the S.T.A.R. Labs particle accelerator explosion in the first place, leading into fiancee Caitlin Snow (Danielle Panabaker)'s pilot claim that Ronnie died in the blast.

Additionally, TVLine reports that 'Smash' alum Andy Mientus will appear in the 11th and 12 episodes as S.T.A.R. labs genius Hartley Rathaway, DC's Pied Piper, who worked at the facility until falling out with his mentor Harrison Wells (Tom Cavanagh). The particle accelerator explosion also destroyed Hartley's hearing, thus inspiring him to create sonic weaponry to target against Wells' newest protege, a certain Flash-y superhero. The 'Flash' villain is also notable as one of the few DC comic characters to openly come out as gay, something the CW incarnation will keep true to.

The latest 'Flash' additions also join such colorful DC characters as Kelly Frye's Plastique, 'Prison Break' stars Wentworth Miller and Dominic Purcell as Captain Cold and Heat Wave, Robert Knepper's returning Clock King, Greg Finley's Girder, and Clancy Brown's General Wade Eiling.

You can check out the first photos of Robbie Amell as Ronnie Raymond below (spoiler alert, they look a lot like Robbie Amell!), but tell us what you think! Did 'The Flash' premiere live up to your expectations? What do you think of the latest wealth of DC heroes and villains to speed their way through the 'Arrow' spinoff?
