Considering that both The Flash and Supergirl are overseen by Greg Berlanti and Andrew Kreisberg, a crossover between the two DC superhero shows seems very likely. The two series also share a similar light-hearted, breezy tone that unlike their other sibling series, Arrow, allows for superhero spectacle and conflict without all the melodrama.
Yet while Arrow and The Flash hold a crossover event each year, generating publicity for both programs, Supergirl has yet to be invited to the party. The biggest reason for this likely lies with the fact that both Arrow and The Flash air on The CW, while Supergirl airs on CBS, but the two networks are very close (the 'C' in CW stands for CBS, after all) and the shows' separate network homes may no longer be the obstacle it once was.
Just about all involved behind the scenes on both Flash and Supergirl are open to the idea of a crossover, with the most recent comments from Berlanti and CW chief Mark Pedowitz suggesting it could come sooner than later. That is, assuming it happens at all, which is something that remains very much unconfirmed.
But CBS president Glenn Geller is also weighing in on the possibility and he isn't ruling anything out, saying to reporters during a TCA press event (via The Wrap) in regard to a Flash/Supergirl crossover:
"I have to be really careful what I say here. Watch and wait and see what happens."
Which, sure, isn't much of a statement either for or against, but it's far from the flat out denial previous CBS entertainment head Nina Tassler was fond of giving. Her reasoning for always shooting down the chance of a crossover was possibly tied to giving Supergirl the time it needed to establish itself, to learn what its identity would be within the growing TV superhero landscape. But now that Supergirl is on firmer footing, is it the right time to revisit the possibility of a crossover?
Already, The Flash season 2 has introduced the concept of the multiverse, making it all too easy for an Earth where Kara's Supergirl flies the skies to exist alongside an Earth where Barry is The Flash and Oliver is Green Arrow. Still, just because they can make their worlds collide doesn't necessarily mean that they should. At least not yet.
The CW is only a week or so from launching its latest DC superhero show -- Legends of Tomorrow, which is itself something of a crossover/team-up show, uniting characters from both Arrow and The Flash. There's also Vixen, the animated, digitally-distributed series that has done quite well on CW Seed and could even sees its leading hero turn up on a live-action CW show.
Suffice it to say, the DC/CW universe isn't in dire need for new characters and Supergirl may be better off continuing to work on establishing its own universe before worrying about crossing over with another. Then again, even a quick tease of such a possibility to close out the season would be enough to send fans into a tizzy!
Supergirl airs Mondays @8pm on CBS. The Flash airs Tuesdays @8pm on The CW. Arrow airs Wednesdays @8pm on The CW. DC’s Legends of Tomorrow premieres on The CW on Thursday, January 21, 2016. Vixen will continue on CW Seed later this year.
