The CW has dropped a new promo for this year’s much-anticipated four-way crossover between “Arrow,” “The Flash,” “Supergirl,” and “Legends of Tomorrow.”

The 15-second clip features the menacing voice of one of the many Earth-X villains that will crash Barry (Grant Gustin) and Iris’ (Candice Patton) wedding in the crossover. “Everyone you care about, everyone you love, they’re going to die,” says the anonymous villain in the video. While the promo doesn’t reveal the identity of the ominous villain, the video gives fans their first look at Earth-X Oliver Queen (Stephen Amell), who is seen pointing a pistol at someone.

Elsewhere in the promo, Cisco (Carlos Valdes) is seen standing inside the church where Barry and Iris are supposed to tie the knot when something suddenly blows up behind him. Caitlin (Danielle Panabaker), who serves as Iris’ maid of honor at the wedding, is also inside the church when the explosion takes place.

At some point in the promo, Barry and Iris are also seen sharing a hug inside the Waverider. And for the final shot of the video, Green Arrow (Amell), The Flash (Gustin), Supergirl (Melissa Benoist), White Canary (Caity Lotz), Firestorm (Franz Drameh), and Alex (Chyler Leigh) are seen lining up for battle.

While it’s unclear why Earth-X villains attack Barry and Iris’ wedding, the synopsis for the crossover revealed that the Earth-1 and Earth-38 heroes are going to get some help from Earth-X heroes The Ray (Russell Tovey) and Citizen Cold (Wentworth Miller) to fend off the unwanted Earth-X visitors.

While the crossover is expected to be action-packed, “Arrow” executive producer told The Hollywood Reporter that “the biggest surprise will be the emotional component of the crossover.” “I don’t think anyone is going to see that coming,” Mericle said. “It’s very much a dark love story. It’s the underpinnings of that that will make the Earth-X element a real contrast to that.”

Surprisingly, it’s the “Legends of Tomorrow” characters that will be bringing the waterworks during the crossover. “You’ll be most surprised that ‘Legends’ is capable of making our audience cry,” “Legends of Tomorrow” executive producer Phil Klemmer told The Hollywood Reporter. “I thought last season really leaned into the comedy, and that Season 3 we tripled down on that. There’s some ludicrous moments. Things get bananas, and yet in this crossover, we have this thing that happens that will honestly move you to tears.”

The crossover, titled “Crisis on Earth-X,” will air across two nights. It begins with “Supergirl” and “Arrow” on Monday, Nov. 27 at 8 p.m. EST, and ends with “The Flash” and “Legends of Tomorrow” on Tuesday, Nov. 28 at 8 p.m. on The CW.
