Some big things are coming up on The Flash, and The CW wants you to know that. The biggest threat that Barry has ever faced is teased in a newly released, and cryptically brief, trailer. Check it out below!

While not mentioned specifically in the new teaser, this upcoming threat is very likely the enormous five show crossover event Crisis On Infinite Earths. It’s clearly posed to be one of the biggest events in the history of the Arrowverse, and likely the biggest crossover event on television ever. I mean they even managed to get Tom Wellings to return as his Superman from Smallville! Additionally, you can check out the brand new poster for The Flash‘s sixth season down below. Make sure to catch the new season when it airs on October 8th at 8pm.
