If you needed any more reason to watch this year's Arrowverse crossover then The CW just gave you a huge reasons because at the end of last night's episode of Supergirl the end tease/stinger was all about Elseworlds!
This year's crossover will involve Arrow, The Flash, and Supergirl and from what we sort of know from photos, trailers, and leaks this year's crossover is going to be epic and feature cameos from all across DC television, including: Smallville, the Arrowverse, and even the '90s Flash!!
We won't spoil anything from this epic stinger, which you can see below, but just be ready for mega levels of hype.
The epic 3 night crossover begins this Sunday, December 9th, with The Flash, continues on Monday with Arrow, and concludes Tuesday with Supergirl. We'll be livetweeting throughout all of the crossover so make sure you join us @Infinite_Pods!!
