The Tomorrow People alum, who is the real-life cousin of Arrow star Stephen Amell, will play Ronnie Raymond, better known in the DC Comics universe as half of Firestorm. On The Flash, Ronnie is a maintenance worker at S.T.A.R. Labs and Dr. Caitlin Snow's (Danielle Panabaker) fiancé, whose fate is more complicated than first imagined. Ronnie plays an integral part in the particle accelerator accident that transforms Barry Allen (Grant Gustin) into The Flash.
"Geoff Johns, Andrew Kreisberg, and myself designed the pilot and series to include Ronnie (a.k.a. Firestorm)—and to actually have someone with Robbie's talent playing the role is beyond exciting," executive producer Greg Berlanti said in a statement. "We can't wait for viewers and fans of the character to check it out."
Amell, who will first appear in the series' third episode, added: "I'm so excited to join forces with Greg Berlanti and The CW again on The Flash. Being brought into the DC Universe is a dream, I can't wait to get started!
Interesting fact: In the comics, Felicity Smoak (Emily Bett Rickards) is the stepmother of Ronnie Raymond.
The Flash premieres Tuesday, October 7 at 9pm on The CW.
