Now that The CW officially has the airing rights to Supergirl, the network plans on giving DC Comics fans the thrill of a lifetime: a four-way crossover event that will cover all of its superhero shows.

DC fans can expect to see a huge event this fall that will feature all four of The CW's main superhero shows: Arrow, The Flash, DC's Legends of Tomorrow and Supergirl.

Executive producer extraordinaire Greg Berlanti promises that this year's "annual crossover event this fall [will] be the biggest one ever."

The network's previous crossover episodes have always done well: all three series often interact and visit each other, but there's usually one major plotline every year that includes every superhero series. This year will see the first such event on The CW with Supergirl, although CBS aired a crossover episode with Supergirl and The Flash earlier this year.

However, that CBS episode featured an alternate Earth from the one where The Flash, Arrow and DC's Legends of Tomorrow exist. The CW will have to work out the kinks with that story line (or ignore it altogether) to bring all four shows together. Supergirl very nearly got the axe from CBS, but got saved at the eleventh hour by The CW, which many fans might argue is where the series belongs in the first place.

Supergirl now not only exists on the same network as the other DC-related TV shows, but it's likely the titular character will also be in their same universe, at least temporarily. The Flash often plays around with multiple Earths and timelines, so it wouldn't be too much of a stretch to come up with some plot device that brings everyone together.

The CW has high hopes for Supergirl, expecting that it will be one of the network's top three shows watched when its second season premieres this fall. The CW also doesn't expect any major changes to the series, although its production will move from Los Angeles to Vancouver, where The CW films its other shows. Although rumors suggest that this might mean losing the character of Cat Grant, The CW president Mark Pedowitz assures viewers that the actress who plays her, Calista Flockhart, wants to continue working on the series.
