This New Trailer For the CW's Biggest Crossover Yet Could Not Be Much Cooler

Next week is going to be one epic week!

The CW’s giant four-show crossover begins on Monday’s episode of Supergirl, and according to this new trailer, we’re in for an incredible treat. 

Some seriously scary aliens, called the Dominators, have come to Earth, and they’re ready to basically exterminate humans. The superheroes and vigilantes of the CW can’t have that, so they band together to make Princess Bride references and remark on each other’s superhero identities. 

They probably also do some world-saving as well, but that’s to be expected. Watch the trailer below!

While most of the trailer is just filled with incredible special effects and one-liners from your favorite quippy heroes, there are a few moments that worry us. That little speech Barry’s giving about how it’s been an honor to work with everyone sounds an awful lot like the kind of speech you’d give when all hope is lost, but hopefully that’s not the case! 

The four-show crossover combines Supergirl, The Flash, Arrow, and Legends of Tomorrow, and will take place over four nights next week, Monday through Thursday, on brand new episodes of each show. 

The event starts on Monday with Supergirl at 8 p.m. on the CW.
