“Suit up for the biggest crossover ever,” the teaser promises, as it features first looks at Black Lightning in action and Brandon Routh’s Kingdom Come Superman. What’s more, the video also offers more glimpses of the Monitor, as well as the Arrowverse’s biggest superheroes banding together, including the Flash, Supergirl, Batwoman, Green Arrow and Oliver Queen’s daughter, Mia Smoak.

What’s more, the teaser debuts the crossover’s first line of dialogue with Oliver Queen’s “We got your backs,” hinting at an epic superhero team-up worthy of the comics.
