Kara Zor-El is the superheroine known as the original Supergirl, appearing in American comic books published by DC Comics. She was created by Otto Binder and designed by Al Plastino. The character first appeared in the story "The Supergirl from Krypton" in Action Comics #252 (May 1959). She is the biological cousin of Kal-El, who went on to adopt the name of Clark Kent and the superhero identity Superman. Her father, Zor-El, is the brother of Superman's father, Jor-El. During the 1980s and the revolution of the Modern Age of Comics, Superman editors believed the character's history had become too convoluted, thus killing Supergirl during the 1985 Crisis on Infinite Earths event and retconning her out of existence. DC Comics Senior Vice President Dan DiDio re-introduced the character in 2004 along with editor Eddie Berganza and writer Jeph Loeb, with the Superman/Batman storyline "The Supergirl from Krypton". As the current Supergirl, Kara stars in her own monthly comic book series. With DC's The New 52 relaunch, Kara, like most of the DC Universe, was revamped. DC relaunched the Supergirl comic in August 2016 as part of their DC Rebirth initiative. In live-action, Supergirl first appeared in the film Supergirl (1984), played by Helen Slater. She later appeared in the television series Smallville, played by Laura Vandervoort, and Supergirl, played by Melissa Benoist, who also appears on other Arrowverse series. Sasha Calle appeared as Supergirl in the DC Extended Universe (DCEU) film The Flash (2023). The character appears in the DC Universe (DCU) franchise portrayed by Milly Alcock, debuting in the film Superman (2025) prior to Supergirl (2026), and will return to Man of Tomorrow (2027). The character has also appeared in numerous television animated series, including Superman: The Animated Series, voiced by Nicolle Tom and My Adventures with Superman, voiced by Kiana Madeira.
Publication history
First appearances The Kara Zor-El version of Supergirl first appeared in Action Comics #252 (May 1959). Otto Binder wrote and Al Plastino illustrated her début story, in which Kara was born and raised in Argo City (unnamed until later issues), a fragment of Krypton that survived destruction. When the city is doomed by a meteor shower, Kara is sent to Earth by her parents, Zor-El and Alura In-Ze (the latter unnamed until later issues), to be raised by her cousin Kal-El, known as Superman. Supergirl adopted the secret identity of an orphan "Linda Lee" and made Midvale Orphanage her home. Supergirl promised Superman that she would keep her existence on Earth a secret, so that he may use her as a "secret weapon", but that didn't stop Supergirl from exploring her new powers covertly. Action Comics #255 published reader's letters-of-comment to Supergirl's first appearance; she had allegedly generated a sizeable and mostly positive reaction. Supergirl, from her debut onwards, became a regular backup strip in Action Comics. She joined the Legion of Super-Heroes, like her cousin had done as a teenager, and in Action Comics #279 (July 1961) she was adopted by Fred and Edna Danvers, becoming "Linda Lee Danvers". Supergirl acted for three years as Superman's secret weapon. She was at last introduced by her super-powered cousin to an unsuspecting world in Action Comics #285 (February 1962). During her first quarter of a century, Linda Danvers would have many professions, from student to student advisor, to actor, and even TV camera operator. She shared Action Comics with Superman until transferring to the lead in Adventure Comics at the end of the 1960s. In 1972 she finally moved to her own short-lived eponymous magazine, before DC merged its Supergirl, Lois Lane and Jimmy Olsen titles into a single anthology title named The Superman Family. In 1982 Supergirl was relaunched into her own magazine.
Death during Crisis on Infinite Earths
In 1985, the maxi-series Crisis on Infinite Earths was conceived as a way to reduce DC continuity to a single universe in which all characters maintained a single history. Despite Supergirl's continued popularity and status as a central member of the "Superman Family", the editors at DC Comics and the creators of the maxi-series decided to kill Supergirl off during the Crisis. According to Marv Wolfman, writer of Crisis on Infinite Earths:
Before Crisis it seemed that half of Krypton had survived the explosion. We had Superman, Supergirl, Krypto, the Phantom Zone criminals, the bottled city of Kandor, and many others. Our goal was to make Superman unique. We went back to his origin and made Kal-El the only survivor of Krypton. That, sadly, was why Supergirl had to die. However, we were thrilled by all the letters we received saying Supergirl's death in Crisis was the best Supergirl story they ever read. Thank you. By the way, I miss Kara, too. The idea of killing Supergirl was first conceived by DC's vice president/executive editor Dick Giordano, who lobbied for the death to DC's publishers. He later said he has never had any regrets about this, explaining, "Supergirl was created initially to take advantage of the high Superman sales and not much thought was put into her creation. She was created essentially as a female Superman. With time, writers and artists improved upon her execution, but she never did really add anything to the Superman mythos—at least not for me." The poor initial reception of the 1984 film Supergirl was also blamed by some sources. In the 1989 tale "Christmas with the Super-Heroes", the soul of Kara appears to Boston Brand / Deadman, cheers him up, and then disappears from continuity until 2001 (see below). Several characters unrelated to Superman soon took on the Supergirl persona, including the Matrix (a shapeshifting genetically engineered life-form that 'defaulted' as Supergirl), Linda Danvers (the result of Matrix merging with the dying Linda Danvers and becoming an Earth-bound angel of fire), and Cir-El (Superman's apparent daughter from a possible future). A heroine resembling the pre-Crisis Kara appeared in Final Crisis: Legion of 3 Worlds #5, along with many alternate universe Legionnaires who were gathered to battle the Time Trapper.
