The epic “Crisis on Earth-X” Arrowverse crossover is now behind us, and so the four CW superhero series will get back to business, airing their midseason finales next week. The network has now released trailers for Supergirl, The Flash, Legends of Tomorrow, and Arrow, and it looks like things are about to get dire for our DC TV heroes.

Titled “Reign,” next week’s episode of Supergirl will see the Worldkiller (Odette Annable) officially make her debut in National City as the show’s Season 3 Big Bad. Interestingly, it’s Mon-El's (Chris Wood) voiceover we hear, so it’s clear he knew all about Reign before traveling back in time from the 31st century.


The Flash will return for a speedy new episode titled “Don’t Run” that sees Barry (Grant Gustin) get taken by DeVoe/The Thinker (Neil Sandilands) and put in a speedster-proof jail. Uh-oh. Elsewhere (as in we don't see it here), Caitlin (Danielle Panabaker) gets snatched by Amunet (fan favorite Katie Sackhoff) to perform a complicated medical task.


Following the tragic events of “Crisis on Earth-X,” the Legends find themselves investigating an Anachronism in a New World Viking settlement in “Beebo the God of War” where they come across the younger version of a certain someone. Oh, and even though we don’t see them in the trailer, Damien Darhk (Neal McDonough) is set to appear, and Matt Ryan returns as John Constantine for a two-episode arc.


Last but not least, following last night’s impromptu wedding, things start off well for Oliver (Stephen Amell) and Felicity (Emily Bett Rickards), who hold a traditional ceremony for family and friends. But Team Green Arrow may have a traitor in their midst, as one of their own is seemingly ready to testify that Oliver is the Green Arrow in “Irreconcilable Differences.”
