Check Out Promo Photos From The Upcoming Arrowverse Crossover Event “Elseworlds”

Promo images from the upcoming Arrowverse crossover event have been released. This three night event is titled, “Elseworlds” and it will kick off with Supergirl on December 9.

An official synopsis for the event has yet to be released, but fans do know that our favorite CW heroes are in for a doozy when an evil scientist switches Barry and Oliver’s lives. Not to mention, Supergirl might just be one of the few people who can sense that something is wrong when she turns up as a prisoner.

Be on the look out as Batwoman, Superman, and Lois Lane will make appearances in the crossover event as well!
