Supergirl To Be Linchpin In DC TV Four-Show Crossover

As we look forward to the fall television season, the question on many a fan’s mind is how exactly will Supergirl be integrated into the already established DC Universe on The CW. In order for the Girl of Steel to regularly interact with characters from other shows, the producers will have to solve the problem of her existing in an alternate universe.

Some fans have theorized this dilemma will be worked out via the “Flashpoint” event over on The Flash, but that really only affects a singular universe, not the multiverse. It’s probably safe to say that the unprecedented four-show crossover that includes the two aforementioned series, along with Arrow and DC’s Legends of Tomorrow, will be where things are streamlined in an organic sense.

In a recent interview, Marc Guggenheim, executive producer for both Arrow and Legends, shed a bit more light on what to expect when questioned about the crossover event at San Diego Comic-Con:

“It’s an external threat from outside the shows that will involve Supergirl coming over to The Flash, then Arrow then Legends of Tomorrow.”

That is a bit of a simple statement, but you have to admit that the nights of the week these shows air on allow for the chain of events to occur quite naturally. Think about it: Supergirl crossed over with The Flash last season when the Scarlet Speedster broke through the multiversal barrier to visit National City. It only makes sense that they be the two to kick off things this time and then eventually involve Team Arrow. Bringing in the crew of the Waverider for the big finish, meanwhile, sounds like the conclusion will be quite grandiose.

As for what that “external threat” might be, speculation will run rampant until we get an official announcement, but the comic book guru in me can’t help but think of the Anti-Monitor as Crisis on Infinite Earths springs to mind. It may be hard to pull off such a larger-than-life villain on TV, but we have seen the visual effects teams on these shows work wonders. Plus, mid-season tentpoles such as these are allotted larger budgets than your average episode.

Supergirl returns for its second season on Monday, October 10 on The CW.
