New Trailer For Arrow, The Flash, Supergirl, Legends Crossover

“Since we’re fighting aliens, I figured we get one of our own,” says Barry Allen (Grant Gustin) in the new trailer for The CW’s big four-night superhero crossover.

Dubbed ‘Heroes vs Aliens’, the extravaganza, which will see the story spanning across four shows, will kick off on Supergirl where The Flash will go over to Kara Danvers’ (Melissa Benoist) Earth to enlist the Kryptonian’s help. The extended trailer welcomes her to “the best team ever” as our heroes are forced to face off against The Dominators, an alien race hellbent on destroying the metahumans living on Earth.

Watch the trailer below…

New footage shows the enemy invaders as they land in their spaceships ready to face off against Team Arrow. Barry compares the new villains to “World War Z zombies” and that “no military can stop them”. But it seems like they aren’t the only threat. Deathstroke makes an appearance and it looks like he’ll have to face off with Sara Lane/White Canary (Caity Lotz). Oliver Queen (Stephen Amell) has a new crossbow while Thea Queen (Willa Holland) is back in her vigilante costume.

The exciting crossover begins with Supergirl, before seeing the story move on to The Flash, Arrow and Legends of Tomorrow.
