Hold onto your butts Arrow fans, the epic crossover event you’ve all been waiting for is only a few days away. In advance of the CW’s sure-to-be epic four-night crossover event, the network dropped a new, extended trailer. The event kicks off on Monday during the latest installment of Supergirl, and continues the rest of the week with Legends of Tomorrow, The Flash, and Arrow.
The trailer shows The Flash speeding into Kara’s Earth to enlist the Kryptonian’s help in a battle against an alien race known as the Dominators, who want to take over the Earth. The new trailer gives viewers a glimpse of the alien foes as Flash welcomes her to the best team-up ever”.
In the extended preview, we see that The Dominators have descended upon Earth in order to destroy all meta-humans before the people of Earth realize they can fashion the meta-humans into a weapon that will destroy the invaders. Resembling the zombies from World War Z, Grant Gustin’s Barry Allen (aka The Flash) fears that no military force can stop them.
“Since were fighting aliens, I figured we get one of our own,” Barry explains in the new trailer as he recruits Supergirl.
However, the Dominators are not the only foes the team will be up against. Deathstroke makes an appearance and it looks as if he will face off against White Canary, played by Caity Lotz.
Tune into Supergirl, which airs at 8 p.m. Eastern on Monday to see the first installment of the four-part event. The crossover continues on Tuesday with The Flash, followed by Arrow on Wednesday — which is also the show’s 100th episode, and ultimately concludes with Legends of Tomorrow on Thursday.
