Supergirl season 6 will be the show's last, and the premiere synopsis teases "an epic battle" Kara must face head on with the help of her friends.
Supergirl's season 6 premiere synopsis teases the start of the show's final run. Supergirl has been on the air since 2015 and a key part of the Arrowverse since it moved to The CW with season 2. Following the massive Crisis on Infinite Earths event, the franchise is going through a transition period. New series Superman & Lois premiered in February, and Batwoman is breaking in a new series lead. Meanwhile, flagship show Arrow ended in January 2020, making The Flash the Arrowverse's most senior show. Black Lightning and Supergirl are on their way out as well, with both set to end this season.
Supergirl season 6 premieres March 30 after nearly a year off the air. Season 5 ended one episode early due to the coronavirus pandemic. The makeshift finale saw Kara and her team work to draw people out of the dangerous VR world that played a major role in season 5. The episode also featured a long-awaited reconciliation for Kara and Lena, who have been on the outs since Lena discovered Kara kept her superhero identity from her. The finale ended on a cliffhanger, with Brainy near death after taking on Lex.
The season 6 premiere synopsis, released by The CW, reveals Brainy does survive the encounter. The episode, titled "Rebirth," also features "an epic battle" with Supergirl and friends taking on Gamenmae and Lex. The full premiere synopsis reads:
As Brainiac (Jesse Rath) lays close to death after trying to stop Lex (Jon Cryer), Supergirl (Melissa Benoist) and team soar in to save him, engaging in an epic battle with Gamenmae (guest star Cara Buono). After beating Leviathan, Supergirl turns her attention to Lex (Jon Cryer) who has used the Obsidian platform to brainwash half the world to love him and follow him at all costs, no matter what horrible things he does. Knowing how dangerous this makes her brother, Lena (Katie McGrath) enlists the entire team – Alex (Chyler Leigh), J’onn (David Harewood), Dreamer (Nicole Maines), Kelly (Azie Tesfai) and Brainiac – to help, but Supergirl realizes that the only way to truly stop Lex is to sacrifice herself.
As the description suggests with its action-packed details, the season 6 premiere will essentially function as the season 5 finale. Many storylines were left up in the air, so those need to be resolved before new arcs can start, presumably in episode 2. The Flash has faced a similar challenge: it ended last season 3 episodes early and is still in the midst of defeating that season's villain. Supergirl has an advantage in that the premiere may feel a little strange, but the next episode can immediately get started on new storylines, which hopefully won't affect season 6's pacing.
This is especially important for Supergirl, since this season will also be its last. It would be disappointing if the show had to spend too much of its farewell run finishing up storylines from nearly a year ago. Instead, Supergirl will be able to focus on crafting a satisfying goodbye for both its characters and viewers. Thankfully, it will be awhile until the series finale; after airing the first part of season 6, Supergirl will go on hiatus in May and return to finish its run this summer.
