Silver Age In her debut story, Kara Zor-El is the last survivor of Argo City of the planet
Krypton. Although Argo, which had survived the explosion of the planet, drifted through space as a self-sustaining environment, the soil of the colony eventually turned into
Kryptonite; and though Kara's father
Zor-El placed lead sheeting above the ground to protect the citizens from radiation,
meteorites pierced the sheeting, and the
Kryptonians died of radiation poisoning instead of replacing the metal. In Supergirl's subsequent backup feature in
Action Comics drawn by artist
Jim Mooney for ten years until 1968, Supergirl adopts the identity of Linda Lee, an orphan at Midvale Orphanage presided over by headmistress Miss Hart. She disguises herself by hiding her blond hair beneath a brunette wig; Supergirl interacts with humans on a person-to-person basis performing good deeds and saving the world by helping one person at a time, and she also devises clever schemes as "Superman's Secret Weapon", saving him many times and avoiding adoption before Superman can introduce her publicly. While temporarily powerless due to the scheming of
Kandorian scientist
Lesla-Lar, who is out to supplant her on Earth, Linda allows herself to be adopted by engineer and rocket scientist Fred Danvers and his wife, Edna. In time, she reveals her secret identity to her adoptive parents on the same day her cousin Superman finally introduces her to the world, in the finale of what was then, at eight chapters, DC's longest-running series, "The World's Greatest Heroine". When frequent dreams about her parents being alive turn out to be real, she builds a machine aided by her engineer father's talent, and brings them both back alive from the "Survival Zone" where they had both teleported during Argo City's final moments. Zor-El and
Alura eventually end up living in Kandor, and when the city in the bottle is enlarged, they both go on to live in Rokyn/New Krypton. Graduating from high school in 1965, Linda Lee goes to college on a scholarship and stays in Stanhope College until she graduates in 1971. During this era, she is helped by her pet cat
Streaky, her Super-Horse pet
Comet, and befriends
Lena Thorul, who had first appeared in the Lois Lane series. Kara is also a member of the
Legion of Super-Heroes, where she becomes close to
Brainiac 5. In addition, Linda has boyfriends from the orphanage (Richard "Dick" Malverne) and from Atlantis (Jerro the merboy). In 1967, Supergirl meets
Batgirl for the first time in ''
World's Finest Comics. Developing a strong friendship, the two characters teamed up many times again, as in Superman Family'' #171, or Adventure #381. In 1969, Supergirl left
Action Comics and became a featured character in
Adventure Comics beginning with issue #381 (June 1969). During the 1970s, Supergirl's costume changed frequently, as did her career in her civilian life. In her secret identity as Linda Lee Danvers, Kara Zor-El took a variety of jobs including graduate student in acting, television camera operator, and student counselor, and finally became an actress on the TV soap
Secret Hearts.
Bronze Age After longtime Superman family editor
Mort Weisinger retired in 1971, the character underwent revitalization under editor Joe Orlando and artist Mike Sekowsky. Wearing a series of new outfits and leaving her adopted foster home with the Danvers family, Linda goes to San Francisco, where she works for KSF-TV as a camera operator and develops a crush on her boss, Geoffrey Anderson. These stories introduced Supergirl's most memorable villain from this period: Lex Luthor's niece
Nasthalthia, or Nasty. Nasty had made two appearances towards the end of Linda's college years, then pursued her to KSF-TV, trying to secure proof of her dual identity. Supergirl starred in her first solo
eponymous monthly series from 1972 until October 1974, when her monthly title merged with ''
Superman's Girl Friend, Lois Lane, and Superman's Pal Jimmy Olsen to produce a new series called The
Superman Family, where she eventually became the steady lead story. Linda worked as a student advisor at New Athens Experimental School before leaving for New York to follow a career in acting with daytime soap Secret Hearts''. In 1982 Supergirl received a second monthly solo series titled
The Daring New Adventures of Supergirl, relocating the character to
Chicago as Linda became a mature student of psychology. Industry legend and former DC publisher
Carmine Infantino provided the penciled art;
Bob Oksner inked. With issue 13 the title was revamped, with a new costume design (sporting a red headband) and the title shortened to just
Supergirl. The series ran until sudden cancellation in 1984, only two months before the character's debut in a big-budget Hollywood film starring
Helen Slater. In the
Crisis on Infinite Earths (1985), numerous heroes from across the multiverse join forces to defeat the
Anti-Monitor. When Superman comes face to face with the Anti-Monitor and is knocked unconscious, Supergirl rushes to save him before he is killed. She is able to fight him off long enough for
Doctor Light to carry her cousin to a safe distance, but is killed by the Anti-Monitor. Afterward, Supergirl is buried on New Krypton and a memorial service is held in Chicago. When the universe is
rebooted, the timeline is altered and all memory of Kara is erased. Kara's spirit appears in
Christmas with the Super-Heroes and
Peter David's run on
Supergirl.
Modern Age In 2004, Jeph Loeb reintroduced Kara Zor-El into post-
Zero Hour (Birthright timeline) continuity during a storyline in the series
Superman/Batman. She is the biological cousin of Superman, and although chronologically older than him, the ship in which she traveled to Earth was caught in a large green Kryptonite meteorite which held her in a state of
suspended animation for much of the journey, making her have the appearance of a 16-year-old girl. Still, Supergirl sometimes saw Superman as a child, due to last carrying him as a baby. DC Comics then relaunched
Supergirl, the first story arc of which was written by Loeb; it showcases Supergirl on a journey of self-discovery. Along her journey, she encounters
Power Girl (Kara Zor-El's counterpart from another universe), the
Teen Titans, the
Outsiders, the
Justice League of America, and arch-villain
Lex Luthor. During the company-wide crossover series
Infinite Crisis (2005), a sequel to
Crisis on Infinite Earths, Supergirl is transported to the 31st century, where she is revered as a member of the Superman family and joins the Legion of Super-Heroes. DC Comics renamed the monthly series
Legion of Super-Heroes to
Supergirl and the Legion of Super-Heroes. Beginning with issue #16. In the limited series
52, which chronicles the events that took place during the missing year after the end of
Infinite Crisis, Donna Troy recalls the original Kara Zor-El and her sacrifice to save the universe. Supergirl returns to the 21st century during the
course of 52. After briefly filling in for a temporarily depowered Superman as guardian of Metropolis, she assumes the identity of
Flamebird to fight crime in the city of
Kandor with Power Girl as
Nightwing in
Greg Rucka's arc
Supergirl: Candor. In 2007, Supergirl appeared in the miniseries
Amazons Attack!. That same year, she joined the
Teen Titans for five issues. during the events of
Supergirl: Candor. Art by
Ed Benes. Conversations with other heroes who maintain secret identities lead Kara to the conclusion that she needs to make a deeper connection with human beings. She accepts
Lana Lang's proposal to present her to the
Daily Planet staff as "Linda Lang", Lana's teenaged niece. In the 2008–2009 "
New Krypton" story arc, in which Superman discovers and frees the real
Kandor and a large number of its citizens, Supergirl is reunited with her father, Zor-El and mother, Alura, though Zor-El is killed by the villain
Reactron. When a planet is formed that the Kryptonians call New Krypton, Kara is torn between her life on Earth, and her obligation to her mother, eventually joining the New Krypton Science Guild. Supergirl subsequently appears in the 2009 miniseries
Justice League: Cry for Justice, and the 2009–2010 storyline "
Blackest Night". The New Krypton storyline would later be resolved in the "
World of New Krypton", "
Superman: Last Stand of New Krypton", "
War of the Supermen" storylines, resulting in the destruction of New Krypton and seeing Supergirl mourn her people. Supergirl subsequently appears in the 2010 "
Brightest Day" storyline, the follow-up to "Blackest Night"., where she joins the Justice League along with
Jesse Quick and
Jade.
The New 52 In this continuity, Kara's ship lands in
Smallville, but hurtles through the Earth and emerges in
Siberia. Kara has no memory of Krypton's destruction, and believes it is only three days since her spacecraft was launched. She learns the truth about Krypton's destruction from Superman, and later journeys through a wormhole to Argo City, which she finds in orbit around a blue sun. She finds the city in ruins, with no explanation of how it met that fate, and is attacked by a female Worldkiller named
Reign before the city plummets into the sun. When Reign and her fellow Worldkiller plan to enslave the Earth, Supergirl returns there to defeat them, and thus adopts Earth as her new home. After several battles with supervillains, including the Worldkillers, superweapons of Kryptonian design, she accepts Krypton's destruction, but continues to grapple with her grief. Her desire to restore Krypton results in her being manipulated into nearly destroying the Earth by another
Kryptonian whom she falls in love with. Upon realizing his manipulation, she kills him by driving Kryptonite through his heart, and succumbs to Kryptonite poisoning. Following her poisoning, Supergirl departs the Earth to die alone. While adrift in interstellar space, she encounters a planet under attack by monsters, and quickly intervenes to save them, unaware that the entire planet is a trap by
Brainiac. She is captured and restrained by
Cyborg Superman, but after a struggle, manages to escape both Brainiac and Cyborg Superman. Returning to Earth, she is sent into the past by the Oracle alongside Superman and
Superboy, where she ensures that a resurrected H'el cannot save Krypton, and sacrifices the planet and her family to save the universe. Back on Earth, she encounters the assassin
Lobo. Initially eager for a peaceful resolution, seeing a kind of kinship with him in their both being lone survivors of their respective worlds (although not truly aware of Lobo's circumstances), Kara's encounter with Lobo would reveal deep mental wounds that attracted a
Red Lantern ring to her. Driven insane by rage, Kara wanders space, attacking everyone in her way, until captured by several Green Lanterns and brought to
Hal Jordan. Immediately recognizing a Kryptonian and unable to remove the power ring without killing her, he brings her to
Guy Gardner, the leader of one of the two Red Lantern factions, who restores her sanity. After some time under Guy Gardner's tutelage and protecting the galaxy as a Red Lantern, Kara is discharged from the Red Lantern Corps. On her way back to Earth, she encounters the leader of the Worldkillers, who are revealed to be parasitic suits of armor. He attempts to assimilate Kara as his host, but she voluntarily subjects herself to Kryptonite poisoning to stop him, and flies into the Sun, killing her and removing him from her body. However, Kara is revealed to be immortal while in the Sun's core and is revived, immediately destroying the Worldkiller. She later helps Guy against
Atrocitus and his Red Lantern splinter group.
Convergence and return of the Pre-Crisis version During the
Convergence story arc, the original Kara Zor-El who had sacrificed her life during
Crisis on Infinite Earths makes an appearance on the amalgamated planet of Telos. At the end of the saga she volunteers herself to once again fight the Anti-Monitor but this time, with the help of her timeline's Barry Allen, the Pre-Flashpoint Superman (in tow with his pregnant wife, Lois Lane), and a repentant
Parallax (Zero Hour Hal Jordan), vows to defeat him for the sake of the multiverse's continued existence. Without it being seen, those left on Telos discover the group was successful and all previous timelines (with the mysterious exception of the pre-Flashpoint/pre-New 52 DC universe) from DC history had been re-established, though the fate of the original Kara Zor-El and her fellows went unmentioned. A few more details of the battle against the Anti-Monitor are later revealed during the New 52 comic mini-series (leading into DC's
Rebirth event). After the defeat of Anti-Monitor, Pre-New 52 Clark and Lois decide to start life anew in the closest universe they can find (mysteriously yet unable to see their old universe even though the rest of the multiverse had been restored) while pre-Crisis Kara Zor-El, along with her contemporary Barry Allen and Zero Hour Parallax/Hal Jordan, decide to find their place in the universe and go off to do so. Her fate as of that story arc is yet to be revealed.
DC Rebirth After the events that led to the death of the New 52 version of Superman, 16-year-old Kara lives in National City with her adoptive parents, D.E.O. agents Jeremiah and Eliza Danvers, where she attends high school and works with the agency as led by
Cameron Chase. As part of her civilian identity, Kara receives special glasses that darken her blond hair when posing as Kara Danvers. Kara also goes on an internship at
Cat Grant's CATCO alongside Ben Rubel, whom she befriends. In her opening arc "The Reign of the Cyborg Supermen", Kara discovers that the cyborg Zor-El, whom she had battled in her New 52 title, is still active and has rebuilt other Kryptonians (her mother Alura included), planning to take over Earth. Supergirl defeats them but vows to help her father regardless of his actions. After National City discovers Supergirl has kept Zor-El's "living" status a secret, they become mistrustful of her.
Mister Bones takes advantage of the heroine's unpopularity and, after taking control of the D.E.O., sends villains in an attempt to bring Kara down. She defeats all of them and regains trust from National City with Ben's help.
The Supergirl Who Laughs Kara is later infected by
The Batman Who Laughs' toxin, causing her to turn evil and joining other infected as part of his
Secret Six before later being cured. She is fired from CatCo by Cat Grant and starts working at
S.T.A.R. Labs.
Woman of Tomorrow Feeling lost and without purpose, Kara drifts through the universe with only
Krypto as a companion. While celebrating her 21st birthday on an unnamed planet by
binge drinking (the planet having a red sun that removes her powers and immunity to alcohol), she is approached by a little girl named
Ruthye and is asked to kill Krem (her father's murderer) in vengeance. Supergirl refuses but, when she is about to leave the planet, Krem attacks and severely wounds both her and Krypto, fleeing in Kara's ship. Kara begins her journey alongside Ruthye and, powerless, saves her space bus crew from a Karpane dragon by taking a red kryptonite drug which causes her to manifest
flame wings.
Supergirl Protecting both Metropolis and the city of Kandor as Supergirl, Kara decides to return to Midvale. There, she is shocked to find that another female Kandorian named Lesla-Lar has assumed not only her previous role as Supergirl, but also her human identity as Linda Danvers. Kara joins forces with Lena Luthor to defeat her, at which point, it is revealed that Lesla assumed Kara's identity to find praise and a place to fit in, as she does not feel welcome or seen on Kandor. Kara agrees to help train Lesla as her own superhero, at which point, Lesla takes the superhero name Luminary. ==Powers and abilities==
