It seemed criminal of The CW to head into next week’s four-part crossover between Supergirl, Flash, Arrow and Legends of Tomorrow without a fresh trailer, but never fear. See Kara’s fiery relationship with Heat Wave, along with fresh looks at the Dominators and more in brand-new footage!

One day out from Thanksgiving, The CW released a brand-new look at the four-part crossover, which kicks off with the tail end of Supergirl’s “Medusa” on Monday, and rides the “Invasion!” all the way through Legends of Tomorrow. Supergirl and Heat Wave is just one of the many adorable interactions we’re bound to discover, while the footage also teases an explanation for that World War II-based “found footage” teaser from Legends of Tomorrow.

If a new trailer weren’t enough, there’s also a mammoth gallery of photos from the four-part event, not to mention a first official clip, or extensive synopses of all four outings (including Arrow’s 100th episode).

Just a few more days until aliens invade, so check out the original “Invasion!” trailer below, and stay tuned for the latest on The CW’s big four-part “Heroes v. Aliens” crossover!
