Arrow’s own Stephen Amell took to Twitter to reveal the official poster for The CW’s upcoming crossover event, Elseworlds. The poster flips the Arrowverse on its head with Amell and The Flash actor Grant Gustin switching mantles.

This year’s crossover kicks off with The Flash on Sunday, December 9, followed by Arrow on Monday, December 10, before it all comes to an end in Supergirl on Tuesday, December 11. Not only will destiny be rewritten during Elseworlds, but it will also mark the Arrowverse’s first foray into Gotham City.  

The crossover event stars Stephen Amell as Oliver Queen/Green Arrow, Melissa Benoist as Kara Danvers/Supergirl, Grant Gustin as Barry Allen/The Flash, and Tyler Hoechlin as Clark Kent/Superman, among others. 

Elseworlds will also mark the debut of Ruby Rose as Kate Kane/Batwoman, Elizabeth Tulloch as Lois Lane, Jeremy Davies as Dr. John Deegan, and Cassandra Jean Amell as Nora Fries, the wife of Mr. Freeze.
