With the Arrowverse‘s three-night “Elseworlds” crossover event less than two weeks away (The Flash “Elseworlds, Part 1” airs Sunday, December 9; Arrow “Elseworlds, Part 2,” airs Monday, December 10; and Supergirl “Elseworlds, Part 3,” airs Tuesday, December 11), the CW released an official synopsis for all three chapters of the story.
If you’re reading this then you probably don’t need the reminder – but just in case, this year’s event brings us Jeremy Davies as Arkham Asylum doctor John Deegan; LaMonica Garrett as Mar Novu/The Monitor; Ruby Rose as Kate Kane/Batwoman; John Wesley Shipp as The Flash (???); Tyler Hoechlin as Superman/Clark Kent, and Elizabeth Tulloch as Lois Lane – and possibly some cool surprises.
