"They have a weapon. A doomsday weapon," says a voice, which sounds like it belongs to Cisco.

While he's saying this, a quick shot of the Earth-X version of Supergirl, wearing her scary face mask.

The clip offers brief glimpses of Barry and Iris in wedding mode, and Barry appears to be clad in some traditional duds. There's also a shot of most of the heroes walking together in slow motion, teasing how prominent Alex Danvers is going to be in the crossover.

We also get shots of Wentworth Miller's return as Citizen Cold, the Nazi version of Captain Cold. And then there's the evil version of Green Arrow, one of two alternate bow-wielders that will debut in the new series.

Crisis on Earth-X is shaping up to be the biggest crossover between The CW's shows yet.
