It has been confirmed that the otherworldly character known as The Monitor will feature prominently in The Flash season 6 premiere. After first debuting on the inaugural CW show, Arrow, The Flash aka Barry Allen was quickly spun off for adventures of his own. The Flash later helped produce further spinoffs such as Legends of Tomorrow and the upcoming Batwoman show. As the most consistently rated of all the current Arrowverse spinoffs, the show has comfortably run for five seasons, with season 6 currently in production.
The Flash season 6 looks to be an especially busy and harrowing time for Barry Allen and his team. As seen at the end of The Flash season 5, the timeline had been so drastically altered that Barry's long-prophesied disappearance was now set to occur at a much earlier point in time. With Crisis on Infinite Earths confirmed as the next crossover event, and already teased in each Arrowverse season finale, season 6 will tackle that ill-fated destiny and its subsequent fallout head-on. Unlike previous crossovers that provided merely a diversion from the collective shows' main threads, Crisis of Infinite Earths is so pivotal to season 6 that showrunner Eric Wallace has revealed that the season will be split up into two distinct storylines - pre-Crisis and post-Crisis.
Speaking with ComicBook at San Diego Comic-Con, Grant Gustin revealed that the build-up to the crossover will be felt straight out of the gate. Gustin, who plays the titular speedster, confirmed that The Monitor (LaMonica Garrett) pays Barry a visit in the season's opening episode with a dire revelation. "The Monitor shows up at the end of our first episode and says the universe is in jeopardy and in order to save the universe, Barry Allen has to die," he said. Gustin went on to refer to Oliver Queen (Stephen Amell) who, to fulfill his end of a deal, was last seen venturing into the unknown with The Monitor. "Barry Allen doesn’t know about this deal Oliver made with the Monitor, either, so someone’s gonna die."
The impending Crisis won't be the only issue facing The Flash and his allies. When the season opens, everybody will still be grieving the death of Barry and Iris's daughter, Nora. After traveling back from the future to help defeat the infamous serial killer, Cicada, she ultimately played directly into Reverse-Flash's cruel machinations. As a result, she was erased from existence right before her parent's eyes. Recent set photos also confirmed the return of the villainous speedster, Godspeed. It's also been confirmed that the comic book villain Bloodwork will serve as a primary antagonist.
It is understandably Crisis on Infinite Earths, however, that has provoked the most excitement. Based on the seminal 1985 comic book storyline by Marv Wolfman, the latest crossover is expected to be an Endgame-level event for the Arrowverse. With such prominent guest-stars as Burt Ward and Kevin Conroy as Bruce Wayne already confirmed, anticipation is sky-high at the prospect of watching the various heroes unite to battle the multiverse-destroying threat of The Anti-Monitor (also Garrett). As such, the news that events will kick off even earlier than assumed will no doubt please fans immensely.
The Flash season 6 premieres Tuesday, October 8 on The CW.
