A new teaser for the special event, kicking off with Supergirl‘s Nov. 28 episode, offers up a first look at the Dominators, an alien race that previously vexed the Legion of Superheroes in the late-1980s DC Comics crossover Invasion!.

“These things are like World War Z zombies,” Barry describes. So in order to defeat them, the speedster enlists the help of all his super friends, including a more-grumpy-than-usual Oliver.

“You really did it this time. You ask for my help, and then we end up the creek!” the archer exclaims at his pal.

Also spied in the promo: Deathstroke’s seemingly implausible return; Felicity and Cisco providing “tech support” for the Legends; and a dramatic spaceship entrance.
