View fullsize

Over the past month, we've seen a few fun promo teasers for The CW's upcoming big DC crossover event series featuring characters from Supergirl, The Flash, Arrow, and Legends of Tomorrow. In the four-part series, we will see them band together to take on an invasion of an alien race known as the Dominators. 

This first full trailer is for the Supergirl kick-off episode for the event, and it looks pretty freaking awesome. It shows some very cool footage of the Dominators laying waste to a group of U.S. soldiers during World War II. There are also some great moments of the team coming together and fighting alongside each other. 

The crossover begins with next week’s episode of Supergirl on November 28th.

The Dominators are coming...can DC's heroes team up to stop them? The invasion begins Monday at 8/7c on The CW!
