The CW has released the full trailer for its four-way crossover event. It begins as Barry a.k.a. The Flash happens upon an alien spaceship and gets attacked by it. The aliens known as the Dominators plan an invasion on Earth.
Realizing that he can't fight them alone, The Flash enlists the help of Arrow, Supergirl and DC's Legends of Tomorrow. But even after the superheroes join forces, they are outnumbered. So they need more backup and thankfully the U.S. soldiers are ready to serve the nation.
The serious issue aside, we'll still see some humor as the superheroes engage in banter. At one point, a curious Supergirl learns of Heat Wave's "colorful" backstory after she asks him about the origin of his alias .
Another promo video, which is shorter than the trailer, gives a look at Felicity Smoak's reaction after Barry tells her, Oliver and Thea about the new villains that are threatening the world.
Collectively called "Invasion!", the superhero crossover event will begin with the November 28 episode of "Supergirl" and continue in all three hours of "Arrowverse" of the week. In the first part, Barry Allen and Cisco Ramon seek Kara's help with an alien invasion on their Earth.
