The third season of Supergirl only just came to an end, but the finale changed the game in some big enough ways that it’s already worth looking ahead to Season 4. The finale ended with Winn and most of the Legion of Super-Heroes off to the future, Brainiac 5 as Winn 2.0 at the D.E.O., James outed as Guardian, J’onn retiring from the D.E.O., Alex taking over his old job, Alura returning to Argo City, and a Kara doppelganger landing in Siberia to kick off Supergirl’s version of the Red Son story from DC Comics lore. Now, while the loss of Winn as a regular means that he won’t be around as much in Season 4, he will be back. The future isn’t quite so certain for other characters. So, read on for our picks of 7 Supergirl characters that need to come back next season!
