Next week on Stargirl, Mike (Trae Romano) discovers Thunderbolt (Jim Gaffigan) and finally gets a taste of that superhero life he's been craving, but his happiness will likely be short-lived as the pink pen is expected to find its way to his friend Jakeem Thunder (Alkoya Brunson) at some point this season, possibly even before the end of the next episode.
Meanwhile, Stargirl (Brec Bassinger), Wildcat (Yvette Monreal), Hourman (Cameron Gellman), and Dr. Mid-Nite (Anjelika Washington) find themselves in over their heads when they come across The Shade (Jonathan Cake), who doesn't seem all that pleased with their arrival.
Plus, based on the latest batch of photos, it looks like Barbara (Amy Smart) will also be getting into some serious trouble.
