A new trailer for The CW's The Flash brings a new threat to Central City and gives fans a taste of what Barry Allen (Grant Gustin) will be up against when he takes on Cicada (Chris Klein) in season 5. Like season 4's big bad, The Thinker, Cicada won't need to be a speedster to pose a threat to Team Flash.

In the season 4 finale, Barry and Iris (Candice Patton) were hit with a shocking development when Jessica Parker Kennedy's mystery girl arrived at Joe's doorstep and revealed herself to be Nora, their daughter from the future. Due to Kennedy being a series regular for season 5, the character is expected to have a major role in the storyline for the upcoming season. Nora admitted in the finale that she made a "big mistake". This "mistake" is most likely the setup for Cicada's introduction.

The CW has released a new trailer for The Flash season 5, which premieres this Tuesday. The trailer highlights the relationship between Barry and Nora while touching on Barry's fears about what will become of him in the future. Nora's lack of a connection with Iris is also hinted at in the trailer. References are made to Cicada, but not by name. Cicada is played up as a mysterious and deadly enemy who wields a black lightning bolt-shaped dagger. Cicada's methods threaten to cause a "war zone" in Central City, but his exact intentions aren't revealed.

It appears that Cicada was defeated by the Flash in the original timeline, before it was inadvertently altered by Nora's "big mistake". Whatever Nora did seems to have impacted the timeline in a way that may shift the odds in Cicada's favor. Team Flash may need Nora's help to defeat him.

It was previously reported that Cicada will have a lot in common with his comic book counterpart, a semi-immortal villain who vows to kill those who have been saved by the Flash. Killing them gives him the life force he needs to stay alive. The show's version of the character is a metahuman with the ability to disable the powers of others. He begins to target other metahumans because he blames them for his own suffering. It's unclear what will prompt Cicada's attacks on Central City, but it will be interesting to see how his battle with the Flash will play out over the course of the season.
