Deadline is exclusively reporting that Nick Tarabay, Jonathan Cake and Ysa Penarejo have signed up to join the cast of DC drama series Stargirl for the upcoming second season.

The series follows High School sophomore Courtney Whitmore as she inspires an unlikely group of young heroes to stop the villains of the past, as the series reimagines Stargirl and the very first superhero team, the Justice Society of America. The Stargirl comics were created by Geoff Johns back in 1999, known as Courtney Whitmore, who receives her powers by wielding Starman’s Cosmic staff and wears the Cosmic Converter Belt which gives her agility and enhanced reflexes.

Nick Tarabay (whose credits include The Expanse and Arrow) will be a series regular, playing the role of Eclipso, one of the main antagonists set to clash with Stargirl’s Justice Society of America in Season 2. Eclipso is a life essence trapped inside a blue diamond. Once owned by the Injustice Society of America, that diamond was stolen in Season 1 by DeLacy’s Cindy, which will result in problems for the JSA going forward. Eclipso is an ancient entity of corruption and vengeance. Brimming with a cold, terrifying darkness, he exploits the flaws of others, reveling in the impure and sinful, sadistically feeding off the dark side of humanity.

Jonathan Cake (whose credits include The Affair and SEAL Team) will recur as the other main antagonist known as The Shade, an English immortal, is a classic antihero from DC Comics who wields magical shadow powers. Tall and slim with an elegant 19th Century way to his speech and manners, he masks the horrors he’s experienced and people he’s lost in all the time alive with wry, witty retorts and a false sense that nothing really matters.

Ysa Penarejo (whose credits include Project Mc² and Red Ruby) will have a recurring role in the second season, though her role is being kept under wraps at this time.

The first season of Stargirl stars Brec Bassinger, Yvette Monreal, Christopher James Baker, Joel McHale, Lou Ferrigno Jr, Henry Thomas, Joy Osmanski, Neil Hopkins, Nelson Lee, Luke Wilson, Anjelika Washington, Meg DeLacy, Jake Austin Walker, Cameron Gellman, Amy Smart, Neil Jackson, Hunter Sansone, Trae Romano and Hina Khan.
