Over the years the heroes of The CW superhero shows have come together to fight one another’s villains, ancient immortals, aliens, and Nazi doppelgangers. This year for their annual crossover they face something far more dangerous: rewriting of reality.
The first full promo teaser for this years event, titled Elseworlds, has debuted and picks up on Barry Allen (Grant Gustin) and Oliver Queen (Stephen Amell) switching lives as the villainous Dr. John Deegan (Jeremy Davies) gains the power to literally rewrite realities from the multiversal being known as the Monitor (LaMonica Garret). They gain help from the arrival of Supergirl, Superman, the debut of Batwoman and Jay Garrick/Flash played by John Wesley Shipp rocking the Flash costume from his 90s CBS Flash series.
This year the Legends are sitting out the crossover as the casts from The Flash, Arrow and Supergirl deal with the threats. As mentioned Ruby Rose debuts as Kate Kane/Batwoman as well as Elizabeth Tulloch as Lois Lane and Cassandra Jean Amell as Nora Fries the wife of the villain Victor Fries a.k.a. Mr. Freeze.
There is a flipping of the schedule for the event as it begins with The Flash on Sunday, December 09 before moving onto Arrow on Monday, December 10 then wrap up on Tuesday, December 11 with Supergirl.
