The Flash Season 5 Trailer

Check out the first trailers for The Flash season 5…

The Flash Season 5 Villain

Chris Klein (ElectionOzAmerican Pie) has signed on as series regular to play next season’s scourge of Central City, Cicada. He’s described as a “grizzled, blue-collar everyman whose family has been torn apart by metahumans, Cicada now seeks to exterminate the epidemic — one metahuman at a time.”

We wrote in detail about the history of the Cicada and what his arrival might mean for the season right here.

The Flash Season 5 Cast

Jessica Parker Kennedy has been promoted to series regular. As anyone who caught the Season 4 finale already knows, Kennedy will be playing Nora, the speedster daughter of Barry and Iris from the future. 

Check her out in costume!

Hartley Sawyer is back as a series regular as Ralph Dibny. Dibny’s arc – Barry’s former police mentor, whose career ended in disgrace for fabricating evidence – was one of the defining parts of The Flash Season 4; an arc that was simultaneously comical and powerfully dramatic, going from sleazy private investigator to reluctantly heroic metahuman The Elongated Man. The character – often confused with DC’s powers-similar Plastic Man – debuted in the pages of The Flash comic book back in 1960.

Danielle Nicolet is back as Joe West’s mind-reading metahuman love interest, Cecille Horton, this time upgraded as a series regular.

While everyone survived Season 4, there’s a big question mark attached to Tom Cavanagh, who saw his Harry Wells exit the show in the season finale. But don’t worry, Cavanagh will return as a new character. “When I was up there shooting for the finale, [Tom Cavanagh] and I sat down and started talking about next season and a new character,” showrunner Todd Helbing told TV Guide. “I think we landed on one that’s pretty funny and unique, and I think it will give Tom a lot of meat to chew on.”

Is that a new Wells…or something else entirely?

Kiana Madeira is Spencer Young, the villainous Spin. We have more details on her character right here.

Kyle Secor will recur on The Flash Season 5 to play Dr. Thomas Snow, Caitlin’s mysteriously resurfaced father, reports EW. Thomas, who’s been missing for decades, is described as an extremely intelligent geneticist. However, there’s (obviously,) a seedy twist regarding his return; a twist that’s likely connected to Caitlin’s innate unlocked Killer Frost powers. 

The Flash Season 5 Story

Here’s the official synopsis for The Flash Season 5! 

Matching wits with The Thinker, who by season’s end had harnessed the powers of all twelve bus metas he created, stretched Team Flash to their limits, but with the help of some new allies, Barry Allen (aka The Flash) and company were able to put a stop to the Enlightenment and save Central City once again. However, with the arrival of Barry and Iris’ speedster daughter, Nora, who arrived from the future admitting to having made a “big mistake,” things are anything but status quo. Will parenthood be the challenge that finally slows The Flash down?
