When The Flash returns on January 19th, 2016, the show will be able to move forward more with its own storyline as Legends of Tomorrow and all its setup material has been dealt with. And there is a lot to deal with as we can see from the latest promo that shows that the Reverse-Flash has entered the picture, a new look at Killer Frost, and the nod towards the Earth-2 Barry Allen entering events as well.
The main cast for this season includes Grant Gustin as Barry Allen/The Flash, Candice Patton as Iris West, Danielle Panabaker as Caitlin Snow/Killer Frost, Jesse L. Martin as Joe West, Tom Cavanagh as Harrison Wells, Carlos Valdes as Cisco Ramon/Vibe, Keiynan Lonsdale as Wally West and Tony Todd as Zoom. The recurring cast includes Victor Garber as Martin Stein/Firestorm,
Robbie Amell as Ronnie Raymond/Firestorm, Shantel VanSanten as Patty Spivot, Teddy Sears as Jay Garrick, Wentworth Miller as Leonard Snart, Malese Jow as Linda Park and Violett Beane as Jesse Quick.
Plot Concept: Following the defeat of Barry Allen’s arch-nemesis Eobard Thawne (aka Reverse Flash), Team Flash quickly turned their attention to the singularity swirling high above Central City, which fans last saw consuming everything in its path. Armed with the heart of a hero and the ability to move at super speeds, Barry charged into the eye of the singularity, but will he actually be able to save his city from impending doom?”
