Supergirl is the name of a superheroine appearing in American comic books published by DC Comics. The original and most iconic Supergirl is Kara Zor-El, the cousin of Superman. Created by writer Otto Binder and artist Al Plastino, she made her debut in Action Comics #252 in May 1959. Conceived as a female counterpart to the Man of Steel, Kara Zor-El was sent to Earth from the doomed planet Krypton to protect her infant cousin Kal-El, but her rocket was knocked off course, causing her to arrive years later as a teenager.
Like Superman, Supergirl possesses a vast array of superhuman abilities under Earth's yellow sun, including flight, super strength, speed, heat vision, and invulnerability, with Kryptonite as her primary weakness. Over the decades, the character evolved from a supporting player in Superman's stories to a headlining hero in her own right, starring in Adventure Comics and multiple self-titled series. Her civilian identity, Linda Lee Danvers, allowed her to navigate life on Earth while secretly protecting National City and the world.
The mantle of Supergirl has been taken up by several other characters in DC Comics continuity, including Matrix, a protoplasmic shapeshifter from a pocket universe; Linda Danvers, who merged with Matrix; and Cir-El, a human briefly believed to be Superman's daughter. Despite these variations, Kara Zor-El remains the definitive version and has become a feminist icon in superhero fiction, representing strength, compassion, and resilience across generations of readers.
