While details remain under wraps for DC Universe's Stargirl series, creator Geoff Johns has confirmed one classic villain that will appear.

Speaking with CBR, Johns confirmed speculation that Solomon Grundy will menace the heroes of the upcoming series, with Zoic Studios rendering the undead villain.

"I'm glad there's a little mystery to it; I don't think everyone quite knows what the show is going to totally be about yet, beyond Courtney and discovering the legacy of Starman and this team coming together," Johns said. "That's fun, knowing we have all these doors to open and cards to turn over and I can't wait for people to see our Solomon Grundy. Our Solomon Grundy's ridiculous! The visual effects house that's done all the work for Stargirl is Zoic Studios and Andrew Orloff is one of the founders of it. The work they put in there, their team blows us away every time we do a visual effects review. Every time they deliver anything, all the different characters and the world that we're tapping into, it's phenomenal work. I can't wait for people to see it, it's truly a cut above the norm."

Solomon Grundy was created by Alfred Bester and Paul Reinman and debuted in 1944's All-American Comics #61 as an enemy of Golden Age Green Lantern and Justice Society co-founder Alan Scott. Since then, he's gone on to become a villain typically associated with Batman.

Speculation on Grundy's inclusion in the show began following the sight of a lumbering figure in the swamp in an extended promo for the series that debuted on The CW. While it is unknown if Grundy will be working alongside the Injustice Society to confront the Justice Society of America, the longtime DCU villain is poised to make a memorable entrance on the live-action series.
