Supergirl

Kara Zor-El of Krypton, cousin to Superman, the longest-serving and most-redrawn heroine in DC’s catalogue. The complete hub: origin, continuity history, powers, cultural significance, and links to deeper sub-entries on her on-screen presence, costume evolution, and independent productions.

Origin

Supergirl debuted in Action Comics #252, cover-dated May 1959. She was created by writer Otto Binder and artist Al Plastino — Binder also having a hand in creating the Legion of Super-Heroes, Mary Marvel, and a substantial portion of the wider Superman supporting cast. The character’s introduction was carefully staged: a previous Superboy story had floated the concept of a “super-girl” in 1949, and Binder had written a 1958 Superman story (#123) titled “The Girl of Steel” that functioned as an audience test for the idea before the real launch a year later.

Her in-universe origin has stayed largely consistent across reboots, even as everything around it has been rewritten. Kara Zor-El is the daughter of Zor-El, brother to Superman’s father Jor-El, and his wife Allura In-Ze. When Krypton exploded, a single fragment of the planet — Argo City — survived intact, blown clear by the explosion with a section of Krypton’s protective atmosphere clinging to it. The survivors lived on this fragment for years before lead poisoning from a meteor strike began killing them off. Kara’s parents, in a deliberate echo of Jor-El and Lara’s sacrifice, sent her to Earth in a small craft to find her cousin Kal-El. She arrived as a teenager, not an infant — old enough to remember Krypton, old enough to grieve, old enough to have already been raised in Kryptonian culture.

This is one of the most underappreciated facts about Supergirl as a character: where Superman is functionally an American who happens to have alien biology, Supergirl is an actual immigrant. She remembers the world she lost. The original 1959 stories handled this primarily as a source of charm, with Kara adapting to teen Earth life under Clark’s mentorship; modern runs, particularly Sterling Gates’s 2008–2011 work and the Tom King / Bilquis Evely Supergirl: Woman of Tomorrow of 2021–22, have leaned hard into the grief and dislocation that the original Silver Age premise glossed over.

Her civilian identity in the original continuity was Linda Lee, later Linda Lee Danvers after her adoption by Fred and Edna Danvers in National City. Linda Lee remains the most-used civilian name across reboots, though the specifics of her adoption, her secret-keeping, and her relationship with the Danvers family have been rewritten repeatedly.

The continuity question — how many Supergirls?

If you’ve ever tried to read Supergirl in publication order and felt lost, this is why: there have been at least five major versions of the character across DC’s history, and several of them are not Kara Zor-El.

The original Kara Zor-El (1959–1985) carried the title for twenty-six years across Action Comics, Adventure Comics, and her own ongoing series. Her death in Crisis on Infinite Earths #7 (October 1985), drawn by George Pérez and written by Marv Wolfman, is one of the most-reprinted single issues in DC’s history — the cover image of Superman cradling Kara’s body is so iconic that it has been homaged, parodied, and recreated dozens of times since. The death was meant to be permanent. DC’s editorial mandate after Crisis explicitly removed Supergirl from continuity so that Superman could be “the last son of Krypton” without qualification.

Matrix (1988–1996) was the post-Crisis workaround. Created by John Byrne, Matrix was a shape-shifting protoplasmic being from a pocket universe, who took on Supergirl’s form and powers. She was, technically, not Kryptonian and not Kara — but she wore the costume, called herself Supergirl, and operated in the Superman role. Most readers treated her as Supergirl in practice even when the canon insisted she wasn’t.

Linda Danvers (1996–2003) emerged from Peter David’s run on the Supergirl series, which is one of the most distinctive and unusual superhero comics of the late 1990s. Matrix merged with a young woman named Linda Danvers, who was on the verge of being killed in a cult ritual; the resulting hybrid retained Matrix’s powers and Linda’s body, and David spent four years writing a series that was as much about religious imagery, fallen angels, and personal damage as it was about superheroics. The run is critically respected and largely forgotten by the broader audience, which is unfortunate.

Cir-El (2003) was a short-lived attempt to reintroduce a teenaged Supergirl as the time-displaced daughter of a possible-future Superman and Lois Lane. The character lasted roughly a year and is generally considered a misfire even by editorial.

Kara Zor-El returns (2004) in Superman/Batman #8, by Jeph Loeb and Michael Turner. The story brought the original Kara back in modified form — still Superman’s cousin from Krypton, still arriving as a teenager, but with her continuity grafted onto the post-Crisis DC Universe. This Kara has been the primary Supergirl ever since, surviving the New 52 reboot of 2011 and the Rebirth relaunch of 2016 with relatively minor modifications. The version on screen in The CW’s Supergirl and the upcoming Supergirl: Woman of Tomorrow film is recognisably this Kara.

The thing to understand about Supergirl’s continuity is that DC has spent more energy explaining away her absence than they ever spent on the absence itself. She was killed off to simplify Superman’s mythology, and she was brought back because the simplification didn’t take.

Powers and abilities

Supergirl has the standard Kryptonian power set under a yellow sun: flight, super-strength, super-speed, invulnerability, heat vision, freeze breath, x-ray vision, telescopic and microscopic vision, and enhanced hearing. Her power level has historically been written as comparable to Superman’s, though specific portrayals vary — some writers depict her as slightly less powerful due to less time absorbing solar radiation, while others (notably Tom King) have written her as functionally equivalent or even more raw-powered than Clark, with the difference being experience rather than ceiling.

Her standard vulnerabilities are Superman’s: kryptonite (in all its colour-coded variants), magic, and red-sun radiation. Like Superman she is generally portrayed as having limited ability to defend against attacks she can’t see coming, since invulnerability is an effect on her body rather than a perception-based shield.

What distinguishes her power set from Superman’s, when writers bother to distinguish, is rarely about the powers themselves and more about how she uses them. Modern writers tend to lean on Kara having grown up on Krypton with Kryptonian training, so her combat sense is often portrayed as more disciplined than Clark’s intuitive Earth-raised approach.

Cultural significance

Supergirl occupies an unusual position in superhero comics: she is one of the most recognisable heroines in the medium, her recognition driven almost entirely by the costume and the relationship to Superman, while her actual stories have been published in fits and starts across decades of editorial uncertainty about what to do with her. She has had at least seven cancelled or relaunched solo series since 1972, more than any other A-list DC character. The pattern is consistent: a new creative team launches a Supergirl book, it builds a devoted readership, it gets cancelled in the 20–30 issue range, and a new team takes another run within two years.

The reason this matters for the character — and for any project covering her — is that Supergirl’s audience is unusually loyal and unusually invested in specific runs. The Peter David Linda Danvers years have a different fan base from the Sterling Gates Kara Zor-El years; the Tom King Woman of Tomorrow readership only partially overlaps with either. There is no single defining run the way there is for Wonder Woman (Pérez) or Batman (Miller, Morrison).

On screen, the picture is different and arguably stronger. Melissa Benoist’s six-season run on The CW’s Supergirl (2015–2021) is the longest live-action portrayal of any DC heroine in television history, and it built a substantial mainstream audience that was previously entirely absent from the comics. The 2026 Supergirl: Woman of Tomorrow film, with Milly Alcock cast as Kara, is the first time a Supergirl film has been positioned as a major theatrical release with the full backing of DC’s reformatted studio strategy.

Related characters

The Supergirl story sits in a wider web of DC characters whose dedicated entries will appear in this section as they’re built out. The most important relationships:

Power Girl — the original Earth-Two Supergirl, Kara Zor-L. Created as the Bronze-Age cousin to a parallel Krypton’s Superman, she’s been a separate character from Kara Zor-El since the post-Crisis reorganisation. Power Girl’s costume, civilian identity (Karen Starr, Starrware Industries CEO), and personality are deliberately distinct.

Superman — first cousin, longstanding mentor figure, and the character against whom Supergirl is most often defined. Most modern runs lean on the contrast: Clark as Kansas-raised Earthling, Kara as Krypton-raised immigrant who actually remembers what was lost.

Wonder Woman — the other DC heroine A-lister, frequent team-up partner across both JSA and JLA continuities, and the only DC heroine whose mainstream cultural recognition exceeds Supergirl’s.

Mary Marvel — the closest structural parallel in superhero comics: a teenage girl with the powers of an adult male counterpart, appearing in stories that wrestle with the same age/power tension that has shaped Supergirl’s portrayal across decades.
