CW's Supergirl To End With Season 6

The CW's sprawling DC superhero universe, the Arrowverse, is about to get a little smaller. Supergirl will be ending its run with Season 6, which is scheduled to premiere next year, GameSpot has confirmed. This is the second Arrowverse series to conclude following the franchise's titular Arrow, which ended after 8 seasons earlier this year.

The show's final season will include 20 episodes and will likely arrive at some point in the midseason of 2021, although no premiere date has been set. Production is scheduled to begin later this month.

In an Instagram post, Benoist offered a comment, saying that portraying the character has been "an honor" and has "taught [her] strength [she] didn't know [she] had."

Supergirl first launched on CBS back in 2015, but made the jump to The CW beginning with Season 2. There, it was able to join its fellow Arrowverse shows like Flash and Legends of Tomorrow for a more cohesive shared universe. Benoist has since co-starred in universe-wide crossover events to bring her character from her alternate Earth to the newly created "Earth-Prime" alongside heroes like Barry Allen and the late Oliver Queen.

In addition to Benoist's Supergirl, the show also introduced a host of other adapted DC characters to the Arrowverse, including Lena Luthor (Katie McGrath), the half-sister of the infamous Lex, and Martian Manhunter (David Harewood) a shapeshifting alien. It is unclear what the show's end will mean for the ensemble, or if any of the supporting cast members will find themselves involved in the other Arrowverse-connected shows. Certainly with all the time-traveling and universe hopping, there is more than enough space for more familiar faces to start cropping up if and when the time comes.

Supergirl Season 6 is slated to air in 2021.
