Looks like The Flash and Supergirl will be meeting in a special crossover episode on CBS.

The episode, titled “Worlds Finest” will be bringing Barry Allen (Grant Gustin) to National City to meet Kara Danvers (Melissa Benoist), but they are keeping mum with more of the episode details.

This won’t be the first time the pair have teamed up either, having partaken in a special cover photoshoot for Variety some time back.

“We are so incredibly excited to announce something that we have dreamed of happening since we started making ‘Supergirl’ – The Flash and Supergirl are teaming up!” said “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 Flash is currently the highest rated show on The CW and Supergirl is CBS’s top ranker for the 2015-2016 season.

The episode is set to hit 28 March 2016 on CBS.
