The Flash & Supergirl Crossover Officially Confirmed

The Flash’s Barry Allen is heading to National City!

Supergirl will stage a crossover with The Flash when Grant Gustin appears as the Scarlet Speedster on the upcoming March 28 episode of the CBS super series, EW has learned.

Details on the episode are being kept under wraps. There’s also no word yet on whether Melissa Benoist will return the favor and appear on The Flash. However, here’s why this crossover is important: If Barry Allen can make his way to National City, that means so too can Oliver Queen (Stephen Amell) in the future.

Though the Emerald Archer is missing from this initial outing, having The Flash first crossover with Supergirlseems a little more plausible considering they’re both metahuman and superhero-heavy shows. But since Barry Allen lives in a neighboring town to Oliver Queen, that means that Kara Danvers (Benoist) hails from the same universe. Therefore, the possibility for a future crossover with Arrow isn’t improbable — it’s just not happening right now.

“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.
