Supergirl is the name of several fictional superheroes appearing in American comic books published by DC Comics. The original and most well known Supergirl is Kara Zor-El, who was the younger cousin of the superhero Superman. The character made her first appearance in Action Comics #252 (May 1959) and was created by Otto Binder and Al Plastino.
Created as a female counterpart to Superman, Kara Zor-El shares his super powers and vulnerability to Kryptonite. Supergirl plays a supporting role in various DC Comics publications, including Action Comics, Superman, and several comic book series unrelated to Superman. In 1969, Supergirl's adventures became the lead feature in Adventure Comics, and she later starred in an eponymous comic book series which debuted in 1972 and ran until 1974, followed by a second monthly comic book series titled The Daring New Adventures of Supergirl, which ran from 1982 to 1984.
Due to changing editorial policy at DC, Supergirl was initially killed off in the 1985 limited series Crisis on Infinite Earths. DC Comics subsequently rebooted the continuity of the DC Comics Universe, re-establishing Superman's character as the sole survivor of Krypton's destruction. Following the conclusion of Crisis on Infinite Earths, several different characters written as having no familial relationship to Superman have assumed the role of Supergirl, including Matrix, Linda Danvers, and Cir-El. Following the cancellation of the third, 1996–2003 Supergirl comic book series which starred the Matrix/Linda Danvers version of the character, a modern version of Kara Zor-El was reintroduced into the DC Comics continuity in issue #8 of the Superman/Batman comic book series titled "The Supergirl from Krypton" (February 2004). The modern Kara Zor-El stars as Supergirl in an eponymous comic book series, in addition to playing a supporting role in various other DC Comics publications.
Since her initial comic book appearances, the character later branched out into animation, film, television, and merchandising. In May 2011, Supergirl placed 94th on IGN's list of the Top 100 Comic Book Heroes of All Time. In November 2013, the character placed 17th on IGN's list of the Top 25 Heroes of DC Comics.
