Stargirl has a weird relationship with the Arrowverse. Though developed as a DC Universe series, Brec Bassinger’s Courtney Whitmore got her screen debut via a brief cameo in “Crisis on Infinite Earths”. The show’s first season then aired simultaneously on the streaming platform and The CW. For season 2 onwards, though, Stargirl is becoming an exclusive CW production. But, thanks to “Crisis”, we know it’s not set within the Arrowverse’s Earth-Prime but on Earth-2.
Nonetheless, word has come out that Stargirl and the Justice Society may be set to crossover with the Arrowverse heroes in time. Insider Daniel Richtman has shared on his Patreon page that The CW has plans for Courtney to team up with the likes of the Flash, Batwoman and Superman, though it’s currently unclear which specific crossovers are in the offing. What’s more, Richtman says that it looks like the series has already been renewed. Presumably, he means a third season is being developed, then, as we know season 2 is due to drop this year.
So that means we can infer that these crossovers won’t occur until season 3. That helps narrow down who Stargirl can cross over with. Both Supergirl and Black Lightning are ending after their next seasons, so don’t expect Courtney to meet Jefferson Pierce of Kara Zor-El – which will probably come as a disappointment to Bassinger, as that was her dream team-up. Maybe the Legends would be the best fit, then. They’ve already met a different version of Stargirl back before the multiverse changed, after all.
Stargirl is likely to deliver another 13 episodes in its second season. Following on from the season 1 finale, expect the mystery of how Starman’s actually alive to be further explored and watch out for new villain Eclipso. Given how packed the network’s schedule is with DC shows this winter/spring, it’ll likely debut on The CW in the late spring or summer.
