Later this month, alien invaders are coming to The CW and it’s going to take the heroes from all four of the network’s DC shows to save the world. Because Supergirl lives on her own alternate Earth, she’s never met the Green Arrow or the heroes from DC’s Legends of Tomorrow. But in the first preview scene from the upcoming crossover, the Girl of Steel leaves quite an impression on her new allies.

Entertainment Weekly debuted the new video, which plays off of last season’s crossover between Supergirl and The Flash. Because of that story, Barry Allen already knew that he could trust Kara, and Vibe’s powers once again allowed him to travel between the worlds to get her help. Note that Team Arrow and the Legends weren’t exactly impressed, until Supergirl briefly demonstrated what she can do.

Remember how the Flash’s speed caused John Diggle to freak out two years ago? That’s still one of the more hilarious moments in the show’s history. But after all of this time, and everything else he’s seen, Diggle’s almost non-reaction to Supergirl is pretty funny as well. It’s interesting to see that Thea Queen and H.R. Wells are also appearing in the crossover episodes, but there’s no sign of The Flash‘s Caitlin Snow in this clip…possibly because of her Killer Frost transformation.

The Heroes vs. Aliens storyline is loosely based on the Invasion miniseries by DC Comics, which featured the alien race known as the Dominators as they attempted to neutralize the threat of humanity’s metahumans and subjugate the planet. The crossover will begin on Monday, November 28 on Supergirl, and continue for three consecutive nights in The Flash, Arrow, and DC’s Legends of Tomorrow.
