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 created to be a female counterpart to the superhero Superman. The character made her first appearance in Action Comics #252 (May 1959) and was created by Otto Binder and Al Plastino.
As Superman's cousin, 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, starring 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" (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.

- Lois Lane (Superwoman) – The first comic ever to feature a female counterpart to Superman is "Lois Lane – Superwoman", a story published in Action Comics #60 (May 1943), in which a hospitalized Lois dreams she has gained Kryptonesque superpowers thanks to a blood transfusion from the Man of Steel. She begins her own career as Superwoman, complete with copycat costume. Similar stories with Lois Lane acquiring such powers and adopting the name "Superwoman" periodically appeared later. One such story is in Action Comics #156 (May 1951), in which Lois accidentally gains those powers through an invention of Superman's arch-foe, Lex Luthor. In the story, Lois wears a short blond wig in her crime-fighting identity, giving her an appearance almost identical to the later version of Supergirl after the latter's real name was specified as Kara Zor-El.
- Queen Lucy, Super-Girl – In Superboy #5 (November–December 1949) in a story titled "Superboy Meets Supergirl", Superboy meets Queen Lucy of the fictional Latin American nation of Borgonia. She is a stellar athlete and scholar. Tired of her duties and wanting to enjoy a normal life, Queen Lucy travels to Smallville, where she meets Superboy and soon wins his heart. Superboy puts on a show with her where he uses his powers to make her seem superhuman; during this contest, she is called Super-Girl. As Super-Girl, Queen Lucy wears a tan dress with a brown cape and Superboy's "S" symbol. Superboy later saves her from a scheming minister. She returns to her throne, leaving Superboy to wonder if she ever thinks of him.
- Claire Kent – In the Superboy #78 story titled "Claire Kent, Alias Super-Sister", Superboy saves an alien woman named Shar-La from a life-threatening crash. After he ridicules her driving, Shar-La turns Superboy into a girl. In Smallville, Clark Kent (Superman's alter ego) claims to be Claire Kent, an out-of-town relative who is staying with the Kents. When in costume, he plays Superman's sister, Super-Sister, and claims the two have exchanged places. As a girl ridiculed and scorned by men, he wants to prove he is as good as he always was. In the end, it is revealed that the transformation is just an illusion created by Shar-La. Superboy learns not to ridicule women.
- Super-Girl – In Superman #123 (August 1958), Jimmy Olsen uses a magic totem to wish a "Super-Girl" into existence as a companion and helper for Superman; however, the two frequently get in each other's way until she is fatally injured protecting Superman from a Kryptonite meteor that a criminal has dropped towards him. At her insistence, Jimmy wishes the dying girl out of existence. DC used this story to gauge public response to the concept of a completely new female counterpart to Superman. In the original issue, she has blond hair and her costume is blue and red like Superman's; indeed, it closely resembles the uniform that actress Helen Slater would later wear in the 1984 movie. Early reprints of this story show her with red hair and an orange and green costume to prevent readers from confusing her with the then current Supergirl character. Much later, the story was again reprinted in its original form.
Original character: Kara
After positive fan reaction to Super-Girl, the first recurring and most familiar version of Supergirl debuted in 1959. Kara Zor-El first appeared in Action Comics #252 (May 1959). The story that introduced the character was drawn by Al Plastino and written by Otto Binder, who had also created Mary Marvel, Captain Marvel's sister and female spinoff. Like Supergirl, Mary Marvel was a teen-age female version of an adult male superhero, wearing a costume that was identical to the older character's other than substituting a short skirt for tight trousers. Binder also created Miss America, a superhero who shared little other than the name with her sometime co-star Captain America.
Reaction at the DC Comics offices to Supergirl's first appearance was tremendous, with thousands of positive letters pouring in.
Issue #8 of the Superman/Batman series originally published in 2004 re-introduced Kara Zor-El into the DC continuity. Like the pre-Crisis version, this Kara claims to be the daughter of Superman's uncle Zor-El and aunt Alura In-Ze. Unlike the traditional Supergirl, Kara is born before Superman; she is a teenager when he is a baby. She is sent in a rocket in suspended animation to look after the infant Kal-El; however, her rocket gets caught in the explosion of Krypton and becomes encased in a Kryptonite asteroid. She arrives on Earth years after Kal-El has grown up and become known as Superman. Due to this extended period of suspended animation, she is "younger" than her cousin. At the end of "The Supergirl from Krypton" arc, her cousin Superman officially introduces her to all the heroes of the DC Comics Universe. Then she adopts the Supergirl costume and accepts the name.
A new Supergirl series, written by Jeph Loeb, began publication in August 2005. The storyline in the first arc of Supergirl depicts a darker, evil version of Kara emerging when Lex Luthor exposes her to Black Kryptonite. The evil Supergirl implies that Kara's family sent her to Earth to kill Kal-El as revenge for a family grudge; at the time, Kara herself refuses to believe this, but later flashbacks indicate that not only is this partly true, but Kara had been physically altered by her father as a child before being involved in several murders on Krypton. This was later revealed to be delusions as a result of kryptonite poisoning. Upon being cured she adopted a personality more like that of her silver age persona.
Kara Zor-El (originally, just Kara; Kryptonians during the Golden Era used a single name for most women, and a two-syllable name for men; thus the addition of the patronymic to the female name is a contemporary convention) is the last survivor of Argo City, which had survived the explosion of the planet Krypton and drifted through space. The city had been covered by a plastic dome for weather moderation, devised by Zor-El, the younger brother of Superman's father Jor-El, a climatologist and engineer. The dome held together a large chunk of land mass under the city as it drifted through space in the general direction of our solar system. However, the bottom-most layers of bedrock were affected by the explosion of the great planet's fissionable core and underwent a slow but steady chain-reaction, turning into green Kryptonite. Using raw deposits and refined materials at hand, the residents of Argo City laid down a ground shield of lead foil to protect them from the developing Kryptonite. Zor-El was also able to fashion a makeshift propulsion system to try to accelerate the city's approach to the Solar System. During the roughly thirty years Argo City traveled through space, Zor-El met and married Alura, daughter of In-Ze, who in turn bore their daughter, Kara—blond like her parents. But before the propulsion system was able to steer the city toward Earth, a deranged citizen named Jer-Em, who was suffering from survival guilt, damaged the exhaust, veering Argo toward a swarm of meteors that crashed into the underside of the land mass on which it rested. As the inhabitants of the colony were being slain by the green Kryptonite radiation released by meteorites shredding the lead barrier, the adolescent Kara was sent to Earth by her father Zor-El in a rocket, to be raised by her cousin Kal-El (Superman). To ensure she would be recognized by Superman, Kara's parents provided her with a uniform which was closely based on the one Kal-El wears as the Man of Steel.
It later develops Zor-El and Alura survived the radiation poisoning that killed everyone else in Argo City by entering the Survival Zone, a parallel continuum akin to the Phantom Zone. They were eventually rescued by Supergirl and decided to live in the bottle city of Kandor. Later, Kara is reunited with her parents. However, that reunion becomes bittersweet, as Reactron kills her father, and her mother dies when New Krypton is destroyed by a trap in Reactron left by Lex Luthor, her own cousin Superman's greatest enemy on Earth, and now her greatest enemy on Earth as well.
On Earth, Kara acquires powers identical to Superman's and adopts the secret identity of Linda Lee, a resident of Midvale Orphanage. She conceals her blonde hair beneath a brunette wig and functions as Supergirl only in secret, at Superman's request, until she can gain, in his opinion, sufficient control of her powers - and the wisdom to properly use them. After she is adopted by Fred and Edna Danvers, Superman decides his cousin is ready to begin operating openly as Supergirl. Her debut was delayed by her powers being stolen by a Kandorian villainess; during this period, the Danvers family adopted her.
She attends Midvale High School as Linda Lee Danvers. In later years, after graduating from Stanhope College, she changes careers several times, holding jobs in student counseling, news reporting, and acting in a TV soap opera titled Secret Hearts. She also attends college in Chicago. Kara has many boyfriends, including Richard (Dick) Malverne, Jerro the Merboy from Atlantis, and Brainiac 5, a member of the Legion of Super-Heroes. She does, however, shun serious commitments, putting her super-career first.
Supergirl's secret identity is a closely held secret known only to Superman, her foster parents, and the Legion of Super-Heroes, of which she is as a member for a time. Like all Kryptonians, Supergirl is vulnerable to Kryptonite. Streaky, her orange cat, acquires temporary superpowers as a result of its exposure to "X-Kryptonite," a form of Kryptonite Supergirl accidentally created in an unsuccessful attempt to neutralize the effects of Green Kryptonite. Comet the Superhorse, a former centaur, is Supergirl's equine companion.
One way DC demonstrated the epic nature of its 12-issue limited series Crisis on Infinite Earths (April 1985 – March 1986) was through the deaths of important characters. In issue #7 (October 1985), Supergirl sacrifices her life to save her cousin and the multiverse from destruction. When the Superman continuity rebooted after the Crisis on Infinite Earths, DC editors felt that Superman should be the sole survivor of Krypton, resulting in Kara being removed. Unlike a number of other characters who are shown dying in the Crisis, no one remembers Kara dying or even ever having existed.
After the events of Infinite Crisis, the sequel to Crisis on Infinite Earths, many historical events from the multiverse are now being remembered. Donna Troy, after her rebirth and inheritance of Harbinger's Orb, recalls the original Kara Zor-El and her sacrifice.
A Post-Crisis Supergirl appears in Supergirl and the Legion of Super-Heroes, in which she is transported to the 31st century, and, as a result of her disorientation, for a time believes she is dreaming her surroundings into existence until finally convinced otherwise. Although her memories of her time with the Legion are erased before she returns to the present, the mental blocks break down upon encountering the pre-Crisis versions of Legionnaires Karate Kid and Triplicate Girl (Una).
Supergirl exhibits new powers, manifesting sunstone crystals from her body; so far she only does so while under great stress (for example, when Cassandra Cain tries to kill her). Supergirl's father implants the crystals within his daughter's body to protect her from malevolent beings from the Phantom Zone. The Zone dwellers are released when Jor-El creates the Phantom Zone Projector and exploits the Zone as a prison. Kara's father, believing that Kal-El is a lure to the Zone denizens, instructs Kara to destroy him. More recent comics have cast this plotline as the result of Kryptonite poisoning from the Kryptonite asteroid in which she was trapped.
A recently completed storyline focused on her promise to a little boy that she would save him. She tries to make good on her promise, following different avenues searching for a cure for his cancer. After he died, she tracks down a villain with the ability to jump through time, but decides not to use that solution, as she would just be doing the same thing as the villain. She accepts that sometimes she cannot save everyone.
As part of The New 52, Kara's origin was rebooted once again. An amnesiac Kara awakens after her lifepod crashes to Earth in the midst of a meteor shower. Upon emerging, she encounters humans and the extent of her powers for the first time. When encountered by Superman, she attacks him, believing him to be an impostor as her cousin was only a baby when she last saw him, and she believed it to only have been a few days since then. 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 in order to save the universe.
Back in Earth, she is attacked by the assassin Lobo, and in the ensuing battle, kills him, while unleashing her rage. A Red Lantern power ring finds her and attaches to her, transforming her into a Red Lantern. 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 manages to restore her sanity. After some time under Guy's tutelage and protecting the galaxy as a Red Lantern, after being discharged from the Red Lantern Corps (because Guy did not want for her to die needlessly against Atrocitus' splinter group), on her way back to Earth, Kara 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 in order to stop him, and eventually flies into the Sun and removes her power ring, killing her and removing him from her body. However, Kara is revealed to be immortal while in the Sun's core, and is restored to life without the power ring or any Kryptonite poisoning, immediately destroying the Worldkiller. She later helps Guy against Atrocitus and his Red Lantern splinter group.
DC Editorial wanted Superman to be the only surviving Kryptonian following DC's post-Crisis reboot of the Superman continuity. As a result, when DC reintroduced Supergirl, she needed a non-Kryptonian origin. Afterward, DC Comics tried to revamp the Supergirl concept, introducing several more non-Kryptonian Supergirls. Eventually, the rule that Superman should be the only Kryptonian survivor was relaxed, allowing for a return of Kara Zor-El as his cousin.
After the post-Crisis reboot in the late 1980s, Supergirl's origin was completely rewritten. No longer was she Superman's cousin or even Kryptonian. In Superman v2, #16 (April 1988), a new Supergirl debuted as a man-made lifeform made of synthetic protoplasm created by a heroic Lex Luthor of a "pocket continuum". Lex implants her with Lana Lang's memories, and she can shapeshift to resemble Lana. Matrix even believes herself to be Lana for a time. She wears a miniskirted version of Superman's costume, but does not have Superman's exact powers. While she can fly and possesses super-strength (like Superman), she also has psychokinetic, shape shifting and cloaking/invisibility powers. (The last makes her undetectable even to Superman.)
Matrix's Supergirl form resembles the pre-Crisis Supergirl. She lives in Smallville with the Kents, who treated "Mae" like their own daughter. While new to Earth, Matrix begins a romance with the DC Universe's Lex Luthor, until she realizes Luthor's villainous nature. She leaves him to find her own way in the world, serving for a time as a member of the Teen Titans and a hero in her own right.
Beginning in September 1996, DC published a Supergirl title written by Peter David. The 1996 Supergirl comic revamped the previous Matrix Supergirl by merging her with a human being, resulting in a new Supergirl. Many elements of the pre-Crisis Supergirl were incorporated in new ways. The woman that Matrix merges with has the same name as pre-Crisis Supergirl's secret identity, Linda Danvers. The series is set in the town of Leesburg, named after Danvers' pre-adoption surname. Linda's father is named Fred Danvers, the same as pre-Crisis Supergirl's adopted father. Furthermore, new versions of Dick Malverne and Comet appear as part of the supporting cast.
As the series begins, Matrix sacrifices herself to save a dying Linda Danvers, and their bodies, minds, and souls merge to become an "Earth-Born Angel", a being created when one being selflessly sacrifices him or herself to save another who is beyond saving. As the angel, Supergirl loses some of her powers, but gains others, including fiery angel wings and a "shunt" ability that allows her to teleport to any place she has been before.[volume & issue needed]
The angelic aspect of Supergirl eventually falls from grace, and Linda and Matrix are separated into two beings. Linda retains some of Supergirl's super-strength and durability, and although she can no longer fly, she can leap an eighth of a mile. Linda acts as Supergirl for a while, attempting to locate her angelic aspect. After she is found in the Garden of Eden and freed from the Demon Mother, Matrix merges with a woman named Twilight and becomes the new Earth-born angel of fire. Twilight uses her healing powers to increase Linda's strength to Supergirl's level and restores her powers of flight and telekinesis. In Supergirl #75 (December 2002), detoured on her way to Earth, Kara Zor-El, the pre-Crisis Supergirl, arrives in post-Crisis Leesburg. After learning that Kara is destined to die, Linda travels to the pre-Crisis universe in her place, where she marries Superman and gives birth to a daughter named Ariella. With the stipulation that her daughter be the exception in the eradication of her alternate "life", Linda ultimately allows history to unfold as it should have, with Kara assuming her rightful but tragic place in the time-stream. However, finding no assurance that Ariella survived the restoration of post-Crisis history, a dejected Linda relinquishes the role of Supergirl, sends a farewell note to Superman, and leaves for points unknown.
Peter David's creator-owned series Fallen Angel, published by DC Comics, features a character, Lee, who is similar to Linda and explores the same themes as his Supergirl series. Prior to Fallen Angel moving to another company, Lee was written in a manner such that she could have been Linda. Though David remained coy as to whether the two characters were one and the same during the DC run of the title, after it moved to IDW, David revealed Lee's origin, which clearly showed that Lee was not Danvers. However, Fallen Angel #14 introduced "Lin," who was said to be Lee's "predecessor" as the guardian of Bete Noire. Lin had recently escaped Limbo, an apparent metaphor for what happened to Danvers after the cancellation of Supergirl. David wrote in his December 13, 2006 blog entry, "Any fans of my run on Supergirl—particularly those who are torqued because Linda Danvers was consigned to oblivion in the DCU--must, must, MUST pick up "Fallen Angel" #14 and #15 when they come out next year." However, since David could not explicitly claim that a character owned by DC was the same as the character he owned, he stated, "Can I say this is Linda Danvers? Of course I can't. However, it's pretty freaking obvious that it is."
According to an interview with Newsarama, the Matrix Supergirl is wiped from existence by the events depicted in the 2005 limited series Infinite Crisis, although Infinite Crisis writer Geoff Johns later stated that Danvers is not. The debate was finally settled in the 2008 mini-series Reign in Hell, where Shadowpact is shown trying to apprehend Linda Danvers before Linda is "recalled" to Hell.
A Supergirl named Cir-El appeared in 2003's Superman: The 10 Cent Adventure #1, claiming to be the future daughter of Superman and Lois Lane. Although she has super-strength, speed, and hearing like Superman, she can only leap great distances. She also possesses the ability to fire blasts of red solar energy. Her alter ego is a street person named Mia. She is later found to be a human girl who was altered by Brainiac on a genetic level to appear Kryptonian; she dies thwarting a plot involving Brainiac 13. Superman (vol. 2) #200 implies that when the timeline realigned itself, Cir-El was erased from existence.
- Siobhan Smythe - Kara's best friend who mistook her for an enemy. They both bonded and later battled Siobhan's father, the Black Banshee.
Even though Supergirl is a Superman supporting character, she is also a Superman Family member, with her own set of supporting characters.
- Zor-El and Alura – Kara Zor-El's biological parents. Zor-El, the younger brother of Jor-El, is a scientist who invents the dome over Argo City and oversees the placement of lead shielding over the ground of Argo City, thus enabling the city's residents to survive the explosion of Krypton. The city drifts in space for about 15 years, the residents clinging to a precarious existence. During that time, the couple have a daughter, Kara, who grows to about the age of 10 or 12, when the city is put in peril when its lead shielding is punctured by meteors, releasing deadly Kryptonite radiation. At this point, Zor-El and Alura In-Ze place Kara in a rocket ship and send her to Earth, which Zor-El had observed using a powerful electronic telescope. Observing a super-powered man resembling his brother Jor-El, and wearing a uniform of Kryptonian styling, Zor-El and his wife conclude the man is probably their nephew, Kal-El, sent through space by Jor-El when Krypton exploded and now grown to adulthood. In later Silver Age accounts, Zor-El and Alura survive the death of Argo City when, shortly before the radiation reached lethal levels, Zor-El projects them both into the immaterial Survival Zone, a separate dimension resembling the Phantom Zone; later they are released from the Zone and go to live in the bottle city of Kandor, preserved in microscopic size at Superman's Fortress of Solitude. In the Silver Age version of the continuity, Supergirl could regularly visit with both her adoptive parents, the Danvers (see below), and her birth parents.
- Streaky the Supercat – Supergirl's pet cat. In the pre-Crisis continuity, he is named after a jagged horizontal stripe of lighter fur on his side, and acquires super-powers after exposure to X-Kryptonite. In post-Crisis continuity, she is a normal housecat Supergirl takes in, whose name is taken from her inability to understand the concept of a litterbox.
- Comet the Super-Horse – Pre-Crisis Supergirl's horse is a centaur accidentally cursed by Circe into being trapped in the form of a horse. In post-Crisis continuity, Comet is a superhero who is a romantic interest of Linda Danvers.
- Fred and Edna Danvers – The foster parents of pre-Crisis Supergirl. Shortly after they adopt Linda Lee from the Midvale orphanage, Superman reveals his cousin's identity to them, so they are aware of her powers. Later, they also learn that Superman is secretly Clark Kent.
- Dick Malverne – An orphan at the Midvale Orphanage who is one of Pre-Crisis Supergirl's romantic interests. While living at the orphanage as Linda Lee, Supergirl meets and befriends fellow orphan, Dick Wilson. Dick suspects that Linda is secretly Supergirl and constantly tries to prove it. Later, Dick is adopted by a couple named Malverne, and changes his name to Dick Malverne. In the post-Crisis continuity, Dick Malverne is a newly arrived resident of Leesburg who befriends Linda Danvers.
- Jerro the Merboy – A merperson from Atlantis who is another of pre-Crisis Supergirl's romantic interests. Superman has a similar relationship with mermaid Lori Lemaris.
- Lena Thorul – Another orphan at the Midvale Orphanage who is one of Pre-Crisis Supergirl's/Linda Lee Danvers's best friends. Lena is unaware that she is the long lost younger sister of Lex Luthor. When Lena was still a small child and Lex was a teen, Lex turned evil after the laboratory accident he blamed on Superboy turned him bald. Lex's parents disowned him and told him to leave home. In order to prevent disgrace to Lena, they moved away from Smallville and told Lena that her brother had been killed in a mountain climbing accident. They changed their family name to Thorul, a rearrangement of the letters in Luthor. Eventually Lena's parents were killed in a car accident and Lena was sent to Midvale Orphanage. A childhood accident while playing in her brother Lex's laboratory empowered Lena with Extrasensory Perception, aka ESP.

A younger version of Laurel takes the superhero codename "Andromeda" shortly before the Zero Hour reboot of the Legion; post-reboot, Laurel remains Andromeda.
- Ariella Kent – Supergirl of the 853rd century, later revealed to be the daughter of post-Crisis Linda Danvers and Silver Age style Superman from the Many Happy Returns story arc.
In other media
Producer Ilya Salkind originally wrote a treatment for the third installment from the Superman film series starring Christopher Reeve that expanded the film's scope to a cosmic scale, introducing the villains Brainiac and Mister Mxyzptlk, as well as Supergirl. The original outline featured a father–daughter relationship between Brainiac and Supergirl and a romance between Superman and Supergirl, even though the two are cousins in the comics. Warner Bros. rejected the outline and made their own Superman III film.
The first live-action depiction of Supergirl was in the eponymous 1984 film, starring Helen Slater as Kara Zor-El/Linda Lee/Supergirl. The film is a spinoff from the Superman film series, to which it is connected by Marc McClure's character, Jimmy Olsen. Its plot concerns Supergirl, Superman's cousin, leaving her isolated Kryptonian community of Argo City for Earth in an effort to retrieve the unique "Omegahedron", which has fallen into the hands of the evil witch Selena (Faye Dunaway). The film was poorly received and did poorly at the box office.
In the seventh season (2007–2008) of the CW's hit show Smallville, Kara is introduced into the cast and was portrayed by Laura Vandervoort. Smallville depicts her as Clark's (Tom Welling) cousin, whose spacecraft became trapped in stasis until the events of the sixth season finale, when the destruction of the dam that the ship had landed nearby disrupted the stasis systems and allowed Kara to wake up. Much of season seven is concerned with Kara's attempts to adjust to life on Earth, especially after learning of Krypton's destruction and the fact that her "younger" cousin is now at least the same age as she. She makes guest appearances in season eight and in the show's tenth and final season, in which she becomes a Justice League member. In the season finale, she is sent into the future by the artificial intelligence of the Fortress of Solitude so that Clark can realize destiny and defeat Darkseid alone.
In 2015, Supergirl debuted on CBS, focusing on the life of Kara Zor-El (Melissa Benoist) as a 24-year-old cousin of Superman, who works by day as an assistant to Cat Grant (Calista Flockhart) in National City. The series's story focuses on Kara learning to be a hero and working with the Department of Extranormal Operations to combat alien and metahuman threats. The series is produced by Greg Berlanti, which allowed the series to cross over with Berlanti's show on The CW, The Flash, which is part of the Arrowverse fictional universe, for an episode which established that Supergirl takes place in a parallel universe to that of The Flash. After its cancellation by CBS, The CW picked up the show for season two, leading Berlanti to promise a four-way crossover with Supergirl, The Flash, Arrow and Legends of Tomorrow. The show has continued this trend in later episodes, with Supergirl receiving a dimensional transporter that allows her to visit the primary Arrowverse setting whenever she wishes, either to seek or provide aid or simply to be a friend. In the second multi-show crossover, Crisis on Earth-X, Supergirl and the Arrowverse characters fight off a Nazi army led by Supergirl's Earth-X counterpart, Overgirl, who is the Fuhrer's leading general in a Nazi-controlled alternative history.
- Supergirl was voiced by Nicholle Tom in Superman: The Animated Series, an American television show. She is depicted as Kara In-Ze, not Superman's cousin as in the comic book, but rather a near-Kryptonian from Krypton's sister planet Argos. Argos was jolted from its orbit by Krypton's explosion into a much further orbit and only Kara survived freezing to death. When Superman finds her, he brings her back to Earth and treats as a cousin. As continued in Justice League Unlimited, she and Superman grow very close, almost like siblings, but she departs when she falls in love with Brainiac 5 of the Legion of Super-Heroes in the distant future, feeling that she had never really fit in on Earth in the present.
- Superman/Batman: Apocalypse, a direct-to-video animated film released in September 2010, largely parallels the origin-story arc launched in the Superman/Batman comic series in 2004, with some minor plot differences. Kara Zor-El, voiced by Summer Glau, is described unambiguously as Kal-El's cousin from Krypton.
- DC Super Hero Girls or DC Superhero Girls (in various countries) is an American super hero action figure franchise created by DC Comics (a subsidiary of Time Warner) and Mattel that launched in the third quarter of 2015. The franchise was announced in April 2015. The range is to include books from Random House, Lego tie-ins and action figures from Mattel. The website was launched in early July 2015.

Other characters including Hal Jordan, Barry Allen, Star Sapphire, Beast Boy, Cheetah, Hawkgirl and Catwoman also appear. Amanda Waller is featured as the principal of the series' setting Super Hero High. Many other DC Comics Heroes and Villains appear in the background as cameos. The story is about at Super Hero High School, well-known DC heroes attend classes and deal with all the awkwardness of growing up (with the added stress of having superpowers).

- Melissa Benoist reprises her role of Overgirl in the animated web series Freedom Fighters: The Ray, set in the same continuity as the CW's Supergirl.
- A LEGO-minifigure version of Supergirl appears as a playable character in LEGO Batman 2: DC Super Heroes, LEGO Batman 3: Beyond Gotham and LEGO Dimensions.
- Supergirl makes a cameo appearance in the IOS version of Injustice: Gods Among Us as a support card.
- Supergirl appears as a playable character in Injustice 2, voiced by Laura Bailey. In the story, her escape pod is retrieved by Black Adam after the events of the first game. She is trained by Black Adam and Wonder Woman into perfecting her powers as they tell her stories of her cousin, inspiring her to become Supergirl. After the Regime and Insurgency ally with each other to take out Brainiac (who was responsible for Krypton's destruction), Kara discovers what the Regime has truly done on the planet and is appalled by her cousin's actions. She and Batman infiltrate Brainiac's ship to stop the tyrant, and when Batman and Superman argue with each other over the Brainiac's fate, she allies herself with Batman, believing that her cousin is behaving more like General Zod than Jor-El. She appears in both of the game's endings, where she will either become a part of Batman's Justice League to recapture what her cousin stood for before Lois' death, or will be imprisoned by Superman until she becomes a part of his Regime. In her single player ending, she works with the Justice League to revive the Kryptonian civilizations of Argo City and Kandor.
