Description: “Supergirl” is an action-adventure drama based on the DC character Kara Zor-El, Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex, and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant. She works alongside her friend and IT technician Winn Schott and famous photographer James Olsen, who Grant just hired away from the Daily Planet to serve as her new art director. However, Kara’s days of keeping her talents a secret are over when Hank Henshaw, head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime. Based on characters created by Jerry Siegel and Joe Shuster, “Supergirl” is from Berlanti Productions in association with Warner Bros. Television, with executive producers Greg Berlanti (“The Flash,” “Arrow”), Ali Adler (“The New Normal,” “Glee”), Andrew Kreisberg (“The Flash,” “Arrow”) and Sarah Schechter (“Arrow,” “The Flash”).

Why Did It End? When Supergirl first premiered on CBS in Fall 2015, it started out with strong ratings but saw those taper off by mid-season. It might have been cancelled by that genre-averse network if not for The CW (which is partially owned by CBS) swooping in to save the show and fully incorporating it into the Arrow-verse. It ended up having a decent run on its new network and its sixth season was announced in advance as its last giving it the chance to wrap up its storylines. But the characters will almost certainly return at some point in other Arrow-verse shows. A Justice League series was teased at the end of Crisis on Infinite Earths, but that may just be for crossover events (a JL series was also teased towards the end of Smallville‘s run but never happened). And Legends of Tomorrow is always looking for new members, so some characters could head that show. So expect Supergirl‘s legacy to continue as long as the Arrow-verse shows remain viable.
