Will Supergirl Go To The Flash Next? Here's What The Creator Says

The DC TV universe will get bigger this upcoming Monday when Barry Allen, a.k.a. The Flash, makes his way from his CW home to CBS’ Supergirl for the highly-anticipated crossover between the Scarlet Speedster and Girl of Steel. While The Flash doesn’t have to go far for his crossovers with Arrow, Supergirl takes place on a different Earth, making it not as easy for Barry and Kara to work together. Still, the door is now open for more of these multiversal team-ups, and the prospect of having Supergirl take a trip to Central City in the future is being considered.

When asked whether Kara Zor-El might someday appear in an episode of The Flash, Greg Berlanti, showrunner for both series, told The Hollywood Reporter that it basically all comes down to the first crossover. As he put it:

We would love that. We're waiting to see the audience reaction from something like this.

For months, the prospect of a Supergirl/The Flash crossover was merely rumored and championed by fans who wanted to see two of DC TV’s lighthearted heroes together. Then it was confirmed in January that Grant Gustin would guest star on Supergirl’s 18th episode, titled “Worlds Finest.” And people have been going crazy talking about it over the past couple of months, so we're fairly confident that viewer reactions will be on the positive side.

Though fans will have to wait for any news regarding a second crossover with the two heroes - whether it happens on Supergirl or The Flash - Berlanti also mentioned that it was the support of viewers that helped this first one happen, which makes it likely that they'll support whatever else they have to in order to get more crossovers.

One of the things that really kept the flame and the torch for it alive was a lot of journalists and the fans online, that consistent feedback throughout the year and enthusiasm for the idea. We always wanted to do it, from the day we cast Melissa. It was exciting to see them onscreen together. But a few things had to go right. We were introducing the multiverse on The Flash and that had to work.

The Flash has already been renewed for a third season, and while Supergirl Season 2 hasn’t been officially announced alongside the other returning CBS shows, the network’s CEO Les Moonves did say that he believed all five of its new shows would likely be renewed. So assuming Supergirl returns for more adventures next TV season, all that would need to be worked out is coordinating Melissa Benoit’s regular schedule with getting her to Vancouver for a week or so of The Flash shoots. If they could get it done for Grant Gustin, then it shouldn’t be too difficult for Benoist.

Following along with his parallel world adventures on his own show, "World's Finest" will see Barry accidentally ending up on Kara’s Earth after testing his speed. While trying to find a way back to his Earth, he’ll help Kara battle Livewire and Silver Banshee.

The first Supergirl/The Flash crossover airs next Monday at 8 p.m. EST on CBS, and if you’re keen on Kara jumping over to Flash’s home turf, make sure to voice your enthusiasm online. Like Berlanti says, it helps to keep the passion going.
