He reunites with "Tomorrow People" producer Greg Berlanti for a meaty role on the "Arrow" spinoff.

Robbie Amell is coming to Central City.

The Tomorrow People star is reuniting with executive producer Greg Berlanti for a major recurring role on The CW's The Flash, The Hollywood Reporter has learned.

Amell is boarding the Arrow spinoff as DC Comics character Ronnie Raymond, otherwise known as one-half of Firestorm. First appearing in the third episode, Ronnie is Caitlin Snow's (Danielle Panabaker) fiance, whose fate is more complicated than first imagined.

A maintenance worker at S.T.A.R. Labs, Ronnie plays an integral part in the particle accelerator accident that transforms Barry Allen (Grant Gustin) into The Flash.

“[Executive producers] Geoff Johns, Andrew Kreisberg and I designed the pilot and series to include Ronnie (aka Firestorm) — and to actually have someone with Robbie's talent playing the role is beyond exciting. We can't wait for viewers and fans of the character to check it out," said Berlanti.

Added Amell: “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!”

In the comics, Ronnie is bonded with another man to form the nuclear-powered superhero, Firestorm.

Though Ronnie/Firestorm has made his way into several animated properties, including Super Friends: The Legendary Superpowers Show, The Super Powers Team: Galactic Guardians and Justice League: Crisis on Two Earths, this will be the character's first appearance in a live-action property.

The Flash casting also marks an Amell reunion: His cousin, Stephen, stars as the title character on Arrow (he makes a cameo in The Flash pilot) and the two briefly shared Wednesday nights on The CW, which was unofficially dubbed #AmellWednesdays.

Amell joins Gustin, Panabaker, Carlos Valdes, Jesse L. Martin, Candice Patton, Tom Cavanagh, Rick Cosnett and John Wesley Shipp in the ensemble.

Amell is repped by WME, Protege Entertainment and Coast to Coast. He recently wrapped production on CBS Films' The Duff and is currently filming the MGM indie Max. Other recurring TV credits include 1600 Penn, Zach Stone Is Gonna Be Famous and Revenge.

The Flash premieres Oct. 7 at 8 p.m. on The CW.
