'The Flash' Season 1 Cast News, Spoilers: Captain Cold and Heat Wave Return, DC Villain and Deathbolt to Appear

Things are getting more explosive and exhilarating in the hit superhero drama TV series "The Flash" as it now draws closer to its season finale. However, this week's episode will definitely not fall short of the excitement the show often brings when it hits the small screens.

A synopsis from The Futon Critic indicates that two previous Rogue villains will return to once again wreak havoc in Central City.

The Flash (Grant Gustin) is yet to have another encounter with the partners in crime Captain Cold (Wentworth Miller) and Heat Wave (Dominic Purcell) as he learns that the two are back in the City. Joining the party is Snart's baby sister Lisa Snart (guest star Peyton List) otherwise known as the Golden Glider, who will definitely amp up the chaos.

Speaking of intensity, TV series headlines cited the arrival of yet another DC super-villain not only in the show but also in "Arrow."

As indicated by Variety, actor Doug Jones will first head to Starling City and meet its billionaire guardian, Green Arrow/Oliver Queen (Stephen Amell) in episode 19 titled "Broken Arrow."

Playing as the electrifying supervilllain named Deathbolt, Jones will also bring his character to Bart Allen's Central City in the show's season finale, Episode 22, which is reportedly titled "Rogue Air."

With all these villains mounting up in the series, executive producer Andrew Kreisberg informed TVLine (via Screen Rant) that there will be even more to come in the next season.

"We're going to do something with all the Rogues. I can't promise it's going to be this season. We know that if the original [1990s] Flash series had gotten a second season, both John [Wesley Shipp] and Mark [Hamill] have told us that the first episode was going to be a giant Rogues episode. And that sounds like maybe a good thing for us to do, what they didn't get the opportunity to do," the showrunner said.
