During a special post-credits scene of the “Stargirl” finale, we get a surprising look at potentially the next major threat for Stargirl and the JSA. If looks are anything to go by, this next villain might be just as dangerous as Eclipso, if not more so.
When Jennie (Ysa Penarejo), a.k.a. Jade, is introduced in Season 2, the new Green Lantern focuses on finding her long-lost twin Todd, which leads her to a youth rehabilitation center called the Helix Institute. In Episode 10, the head nurse of Helix tries to contact someone named Mister Bones and gives details on Jade and her JSA teammates. The finale’s final scene gives us a good look at Mister Bones, played by Keith David, as he and the head nurse go over what they know about the young heroes.
In the comics, Mister Bones is the head of a supervillain group called Helix, which serves as an antagonist for Infinity Inc, a group of young heroes with legacy ties to the JSA (via DC Fandom). So it seems like the ghastly villain and Blue Valley’s finest are on a collision course as Mister Bones says he needs to plan a trip to Nebraska. His reveal may also indicate that we’re much closer to finally seeing the on-screen debut of Jennie’s sibling. In any case, the Season 2 finale of “Stargirl” shows us that we’ll have to wait until 2022 for the series to return and see how everything develops moving forward.
