The CW has released an extended trailer for the upcoming sixth season of The Flash.

The footage sees Barry Allen not only attempting to prevent himself from vanishing but also on "Crisis on Infinite Earths." That being said, we get glimpses of Jay Garrick and The Monitor, of course, as well as yet another new version of Harrison Wells. The trailer then ends with Barry saying, "I have to prepare the team for this crisis. Maybe even a world without The Flash."

Season 6 of The Flash will focus heavily on the upcoming Arrowverse crossover "Crisis on Infinite Earths," picking up immediately after Season 5 and catapulting the team headfirst into looming event. Showrunner Eric Wallace compared the season to "stepping on a landmine," adding that "All of a sudden the future is today, and that turns everything upside-down. You’ll see each member of Team Flash react in their own unique, and sometimes tragic, way."

Returning Tuesday, Oct. 8 at 8 p.m. on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
