Back in September, just before Season 2 of The Flash debuted, The CW Network released a trailer that teased a new Firestorm. This sneak peek showed Jefferson "Jax" Jackson (Franz Drameh) wearing the Firestorm suit, hinting that he will emerge on the show before starring in the midseason series DC's Legends of Tomorrow. Today, the network has released another trailer and poster for next week's episode, The Fury of Firestorm, which shows why the new Firestorm pair was created.

We first saw Firestorm last season, a character formed by the merging of two completely different people, Robbie Amell's Ronnie Raymond and Victor Garber's Dr. Martin Stein. After the events of the season finale in May, fans may not be seeing much of Ronnie any more, after it was confirmed in the Season 2 premiere that he actually died in the first season finale. This trailer shows that Martin Stein's health is deteriorating, and Team Flash must find a new match to save his life. As it turns out, that match is Jax Jackson.

In The Fury of Firestorm, Barry (Grant Gustin) and the team go searching for another Firestorm for Dr. Stein. When the team meets Jefferson "Jax" Jackson (guest star Franz Drameh), Caitlin (Danielle Panabaker) has her reservations about whether Jax is the right person for Dr. Stein. Meanwhile, Iris (Candice Patton) surprises Joe (Jesse L. Martin) while Barry and Patty (guest star Shantel VanSanten) grow closer.

It isn't known if Franz Drameh will appear in more episodes after The Fury of Firestorm, but he won't be the only DC's Legends of Tomorrow character appearing on both Arrow and The Flash. Falk Hentschel (Hawkman) and Casper Crump (Vandall Savage) are also set to appear on both Arrow and The Flash, to set up their characters before DC's Legends of Tomorrow arrives sometime this spring. It was also recently confirmed that the new Arrow villain Damien Darhk (Neal McDonough) will cross over to both The Flash and DC's Legends of Tomorrow.

With Dr. Stein now merging with Jax Jackson, it remains to be seen what The Flash will have in store for Robbie Amell's Ronnie Raymond. It was confirmed during the Season 2 premiere that Ronnie did actually die in the Season 1 finale, but executive producer Andrew Kreisberg told Entertainment Weekly earlier this month that fans have not seen the last of him. While we wait for next week's episode, check out the new trailer below for The Flash.
