Robbie Amell’s portrayal of Ronnie Raymond came to an end when his character sacrificed himself while as Firestrom to stop the Singulartiy. This left his other half Martin Stein, played by Victor Garber, to find a new partner.

Confirmed by, Amell will be reprising his role as Ronnie Raymond, from Earth-Two. His Earth-Two counter part has decided to take a path on the Dark Side as Deathstorm and will be appearing as such in a future episode of the The Flash. 

“We are beyond excited to have Robbie back on The Flash,” executive producer Andrew Kreisberg tells EW. “You can’t keep a good Firestorm down. Only this time, he’s back with a twist, a deadly Earth-Two version of our beloved Ronnie in the form of Deathstorm.”

Deathstorm will join his Earth-Two love interest in Caitlyn Snow who is of course Killer Frost.

The Flash returns Tuesday, January 19th at 8pm ET on The CW.
