In “Invincible,” after Zoom (Teddy Sears) unleashes an army of Earth-2 meta-humans on Central City, Barry (Grant Gustin) is shaken when he sees their leader is the Black Canary’s Earth-2 doppelganger, the Black Siren.
While the 43-year-old actor will not be recurring on the show as Leonard Snart/Captain Cold, he will still make appearances on the series.
Wentworth will also be appearing on other DC shows from executive producer Greg Berlanti throughout the season, effectively making him a series regular in the universe.
“We always knew that he wouldn’t be a permanent member of The Waverider,” Greg told Deadline. “We also knew we loved him on the show and all the shows, Flash as well.”
Greg added that while Wentworth “won’t be part of the team of Legends on board of The Waverider next year, he will have a very active role on the show… In success we hope to continue with other characters finding their way across all the shows.”
The other shows that Greg is producing are The Flash and Arrow.
