The CW has dropped a full-length trailer — that’s just over two minutes, but who’s counting — for its super-soon Arrowverse crossover event, bringing heroes from Arrow, The Flash, Supergirl, and Legends of Tomorrow together to combat a new alien invasion from the Dominators. The “Heroes Vs. Aliens” event kicks off on Monday at the end of Supergirl and will dominate every DC TV show for the whole week, including Arrow’s 100th episode.

The last trailer showed us some cool stuff, particularly Supergirl’s introduction to the rest of the main Arrowverse crew, but this new one shows a lot that is integral to the main plot of “Heroes Vs. Aliens.”

We get the scope of the invasion with a nice shot of the alien ship heading towards Earth, and it looks like the Flash might be the one to discover an alien ship and make first contact with the Dominators.

Lyla seems to have at least some intel on the Dominators from A.R.G.U.S. and pays a visit to S.T.A.R. Labs to deliver the info, and we see a rehashing of the squeal-worthy introductions when everyone meets each other, including the much anticipated romantic tension between White Canary and Supergirl. This makes sense as a progression, as The Flash airs on Tuesdays so he will be the one bringing everyone together in Part 2.

“We must exterminate your kind before the scourge of your planet becomes the scourge of ours,” says some kind of Dominator, maybe a leader of sorts. Best of luck, bud!

The Legends encounter the Dominators in what looks like World War II, which doesn’t make a ton of sense just yet, but timey wimey is wibbly wobbly. There’s some lighter moments, specifically between Supergirl and Heat Wave, but the troubling bits come when we see what looks like Oliver, Thea, Sara, Diggle, and Ray as prisoners on a spaceship … maybe?

When the dust settles, we get that fun little line from the Green Arrow that everyone is “up the creek” and a totally glorious lineup shot. Take a look at the full trailer below:

The DC TV crossover event, “Heroes Vs. Aliens,” kicks off on Monday, November 28 at the end of Supergirl and continues through The Flash, Arrow, and The Legends of Tomorrow all next week.
