The CW wrapped up Season 1 of its new series Stargirl back in August, but it's already been renewed for Season 2, which is expected to debut sometime in 2021. During the DC FanDome panel for the show, the cast and crew teased a few things coming back for the next season--including some big-name JSA villains.

Spoilers for the end of the first season coming up, so consider this your final warning. In the season finale of Stargirl, the villainous Solomon Grundy is released, damages STRIPE and Hourman takes Grundy down. However, if you're familiar with Grundy from the comic books, you know he just comes back again and again and again. The same can be said for Grundy on Stargirl.

"I'm excited for people to see more Grundy," said executive producer Geoff Johns. "He's not gone, just yet. Cameron [Gellman] knows where we're gonna do with Grundy. So [there are] cool story ideas for Grundy coming up."
