The Arrowverse’s bananas body-swap crossover this year — titled "Elseworlds" — is bringing plenty of comedy to its story of various superfishes out of superwater. The Green Arrow is the Flash and vice versa thanks to the mysterious machinations of Arkham Asylum’s John Deegan, but now, thanks to a new promo clip, fans have their first sneak peek at what’s at stake for Supergirl. Rather than swapping bodies, it seems she’s simply had a run of bad luck... or worse.

That’s because The CW’s most powerful woman has found herself behind bars.

Take a look:

Melissa Benoist's Kara Danvers is locked up at STAR Labs in one of the pods used to contain some of the show’s most dangerous and powerful metahumans. Her jailer? Her sister, Alex. And apparently things have soured between them... that or Supergirl has quite a different reputation under Deegan’s version of reality. "You are as despicable as they come, you are dangerous, and you are clearly crazy," Alex says before shutting her sister away.

That good-is-evil attitude may explain why fans’ll get to see Tyler Hoechlin's black-suited Superman — though no word on how bad Elizabeth Tulloch's Lois Lane and Ruby Rose’s Batwoman are in this twisted reality.

Elseworlds' three-night and three-show event begins on Dec. 9.
