Crisis on Infinite Earths is looming large over all the characters that call the Arrowverse, and it’s multitude of realities, home, no more so than Barry Allen/The Flash. All the way back in season one it was revealed that one day a Crisis would happen that would cause Barry to vanish.
Because of lots of time shakeups over the years, that Crisis is coming sooner than expected and in the new season six trailer for The Flash shows that Team Flash is not ready to let their friend become lost to the crises.
The season synopsis states:
Team Flash spent the last year dealing with not one but two Cicadas, the return of Eobard Thawne (a.k.a. Reverse Flash), and the surprise arrival from the future of Barry and Iris’s daughter Nora West-Allen, (a.k.a. XS). The stakes were higher than ever during the season 5 finale, which culminated in Barry and Iris losing their daughter after only just getting to know her. How will they deal with saying goodbye to their speedster daughter, and what does Thawne’s escape mean for Team Flash?
The Flash returns to The CW on October 08. Crises on Infinite Earth’s stretches across Arrow, Supergirl, The Flash, Batwoman and DC’s Legends of Tomorrow with three of the five episodes ariing in mid-December and the last two held off till shows return in mid-January.
