After seemingly trying to dodge the "Supergirl" TV series, CBS has finally added the superhero drama to the 2015–16 television season. The series, based on the DC comic book series "Supergirl", will revolve around Superman's cousin Kara Zor-El or Kara Danvers, as humans would know her.

Greg Berlanti, who also helped create "Arrow" and "The Flash" on The CW, is the execute producer for "Supergirl". "Arrow" and "The Flash" are also based on DC comic universe superheroes. The titular role will be played by the "Glee" alum Melissa Benoist. "Supergirl" is a 24-year-old Kryptonian who has been hiding her superhuman powers for her entire life.

Although the air date of the show will only be confirmed next week, it will come out sometime in 2015.
