In addition to the main characters, The Flash season 6 cast consists of some newcomers to the franchise - both good and bad. Last season saw the eponymous superhero Flash go against the villain Cicada (as well as a future version of Cicada), but while Team Flash won out in the end, Nora West-Allen aka XS was erased from existence.
Thanks to a new timeline emerging, The Flash season 5 finale resulted in the Flash's disappearance from the universe moving up from the initial 2024 date (from the first season) to 2019. A huge part of that was to set up the rest of the Arrowverse's Crisis on Infinite Earths crossover event, which was confirmed shortly before The Flash was officially renewed for season 6.
The Flash season 6 continues Barry Allen's story as Central City's superhero, and the season's cast is better than ever before - with some familiar faces returning throughout the season and others joining the Arrowverse for the first time. Here's the full Flash season 6 cast list.
