Last week, The CW Network released a trailer forSeason 2ofThe Flash, which teased thatDC’s Legends of TomorrowstarFranz Drameh(Jay Jackson) will eventually become the newFirestorm. While it isn’t known when this transition will actually happen, the network has released another trailer which shows the return of current Firestorm, played byRobbie Amell. It’s worth noting that the other half of Firestorm,Victor Garber’s Dr. Martin Stein, will also be one of the series regulars onDC’s Legends of Tomorrow.

Last week’s trailer revealed a brief glimpse ofBarry Allen(Grant Gustin) alongsideDC’s Legends of Tomorrowcharacter Jay Jackson (Franz Drameh), who is seen wearing a modified version of the Nuclear Man suit worn byRobbie Amelllast season. It isn’t known whenFranz Dramehwill appear on The Flash, but it seems his appearance will help set up the new Firestorm that will be showcased inDC’s Legends of Tomorrow. The move makes sense, sinceRobbie Amellwas never confirmed as part of theDC’s Legends of Tomorrowcast. But it remains to be seen how he will now be used in The Flash. In the comics, there have been other characters who have taken over the Firestorm Matrix, such as Mikhail Arkadin and Jason Rusch.

While it hasn’t been previously announced thatFranz Drameh’s Jay Jackson will appear on The Flash, it has been confirmed that characters such as White Canary (Caity Lotz) and Hawkman (Falk Hentschel) will be introduced in bothArrowand The Flash beforeDC’s Legends of Tomorrow. It seems possible that fans will get a glimpse of everyDC’s Legends of Tomorrowcharacter on both of the hit shows before this midseason series kicks off, especially since the network used the same tactic to introduce Barry Allen before The Flash.

Tony Toddhas joined the cast this season as the voice of main villain Zoom. Executive producerAndrew Kreisbergrevealed they wanted to do something different this season, when it came to the main villain. Last season, the producers modulatedTom Cavanagh’s voice when he was in costume as Reverse Flash, to hide his identity fromBarry Allen(Grant Gustin) and the rest of Team Flash. This season, whileTony Toddwill provide the voice forZoom, fans will be left to guess who is actually inside the Zoom suit.

The show will also feature two characters from the midseason seriesDC’s Legends of Tomorrow,Falk Hentschel’s Hawkman andCasper Crump’s Vandall Savage.
