The second season of the American television series The Flash, which is based on the DC Comics character Barry Allen / Flash, sees Barry recognized as a hero in Central City after saving the city, only to face a new threat from a parallel universe in the form of the speedster Zoom, who seeks to eliminate everyone connected to the Speed Force throughout the multiverse. It is set in the Arrowverse, sharing continuity with the other television series of the universe, and is a spin-off of Arrow. The season was produced by Berlanti Productions, Warner Bros. Television, and DC Entertainment, with Andrew Kreisberg, Gabrielle Stanton, Aaron Helbing, and Todd Helbing serving as showrunners.
