All The Flash And Supergirl Characters That Will Be Singing For The Musical Crossover

The CW's DC universe is currently comprised of four primetime series, and those four shows provide unique opportunities for crossover. The Flash and Supergirl will soon cross over for a superhero collaboration unlike anything else on TV. Key characters from both shows will team up in a musical extravaganza that will see plenty of singing. We've known about the crossover since August. Now, the list of characters who will be dusting off their pipes for the event has been released, and it's a doozy. Take a look!

It's no surprise that Grant Gustin and Melissa Benoist will be bursting into song in the crossover. The Flash and Supergirl stars both appeared on Glee, and Gustin has even already done a bit of singing as Barry Allen. The pair have proven that they have what it takes to sing and dance on the small screen. Who knows? Maybe the duo will get a duet at some point in the crossover.

Jesse L. Martin and Victor Garber aren't too surprising either. Martin originated the role of Collins in the smash Broadway hit Rent, and Garber is a Tony Award-nominated Broadway singer himself. Both men have also gotten to sing in The CW's DC universe as well. Martin played an Earth-2 lounge singer version of Joe West on The Flash, and Garber did a bit of warbling when the Legends took a trip to the 1940s on Legends of Tomorrow. Given that Garber's character actually originated on The Flash, it makes sense that he would be brought back for a musical crossover.

Jeremy Jordan and Carlos Valdes have theatrical singing experience as well, although in lesser known roles than Jesse L. Martin and Victor Garber. Still, Winn and Cisco should be able to keep up with their singing pals in the crossover. The biggest surprise of the musical lineup has to be John Barrowman.

John Barrowman has contributed his vocals to many different productions throughout his career, and he has proved himself a remarkably talented singer. The surprise comes from the fact that Barrowman has primarily appeared in The CW's DC universe as an Arrow villain. Malcolm Merlyn has brought his villainy to Legends of Tomorrow for Season 2, and he's dropped by The Flash in the past, but the crossover will be the first time that any of the Supergirl crowd have reason to interact with him. It should be interesting to see how the episodes manage to logically bring Malcolm into the story so that Barrowman can sing.

Of course, logic can only go so far on any musical episode. Still, the teams at The Flash and Supergirl have found a way to justify characters bursting into song. The villain of the crossover will be none other than Music Meister, who possesses the ability to force those around him to sing. DC Comics reports that the crossover will kick off in the final minutes of Episode 16 of Supergirl Season 2 and carry over into Episode 17 of The Flash Season 3. It seems that the majority of the action will take place on Barry's Earth-1 rather than Kara's Earth-38.

The musical crossover begins on Supergirl on Monday, March 20 at 8 p.m. ET on The CW, then finishes up on The Flash on Tuesday, March 21 at 8 p.m. ET. Check out our midseason TV premiere schedule to see when your other favorite shows hit the airwaves in the near future.
