Supergirl is a superhero who was created for DC Comics by Otto Binder Al Plastino in 1959. Like her cousin Superman, she is an alien from the planet Krypton who exhibits extraordinary powers on Earth.
The character has been interpreted in many ways over the decades, appearing in a number of comic book titles, and has translated to animation, video games, a live-action feature film in 1984, and a television series that premiered on CBS in 2015.
