In what marks the very first time DC superheroes from two separate networks will join together while both shows are still on air, the Scarlet Speedster (Grant Gustin) will pay titular heroine Supergirl (Melissa Benoist) a visit on the March 28th episode of the CBS series.
While there is no word yet as to what context The Flash's appearance will have in Supergirl's storyline, it's the first big step made in intermingling the universes of all our favorite comic book characters.
“We are so incredibly excited to announce something that we have dreamed of happening since we starting making Supergirl —The Flash and Supergirl are teaming up!” said The Flash and Supergirl executive producers Greg Berlanti and Andrew Kreisberg. “We want to thank Grant Gustin for making the time to come visit (on top of his already immense workload) and all of the folks at CBS, The CW, Warner Bros., and DC for working this out. And finally thanks to the fans and journalists who have kept asking for this to happen. It is our pleasure and hope to create an episode worthy of everyone’s enthusiasm and support.”
The meet-up between Barry Allen and Kara Danvers has been in the makings for quite some time now, with many fans questioning when Berlanti and Kreisberg would work out a deal with the networks, Warner Bros, and DC. While crossovers aren't exactly an uncommon occurrence (i.e the regular tagteam work of Arrow and The Flash), scheduling a mashup with characters on different networks, as well as opposing studios is never an easy task. After the mention of a crossover at the TCA's this past winter, it appears Berlanti came through after all.
With the upcoming March episode of Supergirl, combined with DC's very own Batman/Superman crossover in the same month, it's clear that the reign of superheroes is just getting bigger and bigger, with no means of slowing down.
You can catch The Flash Tuesday nights at 8PM ET on The CW, and Supergirl on Monday nights at 8PM ET on CBS.
