It's officially official: "Supergirl" is landing at the CW this fall, switching networks from CBS while retaining its regular timeslot. "Supergirl's" new network has celebrated this announcement by releasing a trio of promotional videos that integrate Kara Zor-El into the CW's larger DC universe.

The first teaser features footage from this past season's "Supergirl"/"Flash" crossover episode.

The extended teaser works in footage from "Flash," "Arrow" and "Legends of Tomorrow" along with clips from "Supergirl's" CBS run. And with a four-way crossover reportedly in the works between all four shows, odds are fans will get to see these characters really interact this season.

And finally, the CW has released a clip from March's "Worlds Finest" episode, which shows the Flash and Supergirl meeting.

"Supergirl" will air on Mondays at 8 PM ET starting this fall on the CW.
