The Arrowverse is filled with former cast members from Glee, including Grant Gustin, Melissa Benoist, Blake Jenner, Peter Facinelli, Charlotte Ross, Nolan Funk, Gregg Henry, Bex Taylor-Klaus, Victor Garber, and Darren Criss. You can now add one more name to that list, as Max Adler, who played David Karofsky, has signed on for an upcoming episode of The Flash.
According to FlashTVNews, Adler will play Jaco Birch, an obsessive music fan who loves classic heavy metal. He’s a roadie for some of the newer, contemporary metal bands — and he likes to set things on fire. The name doesn’t directly tie to any existing DC character I can find, but that doesn’t mean he’s not one. The name Jaco might be an homage to the late jazz bass legend Jaco Pastorius, who died at the way-too-young age of 35.
Besides his time on Glee, Adler’s credits include Switched at Birth and an episode of Criminal Minds.
The most recognizable fire-related Flash villain is, of course, Heat Wave / Mick Rory, who is currently a part of DC’s Legends of Tomorrow and played by Dominic Purcell. There are also similar villains in Firefly, currently in use on Gotham (portrayed by Michelle Veintimilla) and Firebug who has had three different versions over the years.
The Flash airs Tuesdays at 8 p.m. ET on the CW.
