Supergirl

Concept

Created as a female counterpart to Superman, Kara Zor-El shares his superpowers 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, The Daring New Adventures of Supergirl, which ran from 1982 to 1984. Supergirl was originally introduced in Action Comics #252 as the cousin of the publisher's flagship superhero, Superman in the story The Supergirl from Krypton. In most depictions, she is an alien from the planet Krypton, possessing a multitude of superhuman abilities derived from the rays of the yellow Sun. Other mainstream characters have taken the name Supergirl over the years, with decidedly non-extraterrestrial origins, such as that of a superhuman artificial life-form. The 2016 miniseries Supergirl: Being Super written by Mariko Tamaki and penciled by Joelle Jones is a coming-of-age take on Supergirl's origins. It depicts Kara as a seemingly ordinary teenager living in the rural Midvale with the Danvers, since the couple found her inside a pod in the middle of a field. Kara grows up aware of the pod and her unknown origins (which are glimpsed in dreams) and struggles to live a normal life as she discovers her abilities, which she keeps a secret even from her closest friends.

Because of changing editorial policy at DC, Supergirl was killed off in the 1985 event Crisis on Infinite Earths. DC Comics subsequently rebooted the continuity of the DC Comics Universe, re-establishing Superman as the sole survivor of Krypton's destruction. Post-Crisis, several characters unrelated to Superman assume the role of Supergirl, including Matrix, Linda Danvers, and Cir-El. Following the cancellation of the third Supergirl comic book series (1996–2003), 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 Superman/Batman. This modern Kara Zor-El stars as Supergirl in an eponymous comic book series and additionally in 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.

Precursors

Superwoman – The first comic 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.

Supergirl – 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 Supergirl. As Supergirl, 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.

Super-Sister – 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 (Superboy's alter ego) claims to be Claire Kent, an out-of-town relative who is staying with the Kents. When in costume, he plays Superboy'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 film Supergirl. 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

Debut

After positive fan reaction to Super-Girl, the first recurring and most familiar version of Supergirl debuted in the year 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. Years earlier, Binder had co-created Mary Marvel, the sister of Captain Marvel. Like Supergirl, Mary Marvel was a teenage 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 Marvel Comics' Miss America, a superhero who shared little other than the name with her sometime co-star Captain America.)

Reaction to Supergirl's first appearance was tremendous, with thousands of positive letters pouring into the DC Comics offices.

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 is caught in the explosion of Krypton and becomes encased in a Kryptonite asteroid. She arrives on Earth years after Kal-El, who has grown and become known as Superman. Owing to this extended period of suspended animation, she is "younger" than her cousin. At the end of "The Supergirl from Krypton" arc, Superman officially introduces her to all the heroes of the DC Comics Universe. 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. However, these matters were later revealed to be delusions as a result of Kryptonite poisoning. Upon being cured, she presents a personality more like that of her Silver Age persona.

Biography

Kara Zor-El (so named because on Krypton, women take the full name of their fathers) 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 Jor-El, a climatologist and engineer, the father of Superman (Kal-El). The dome held together a large chunk of land mass under the city as it drifted through space in the general direction of the Solar System. The land is converted into green kryptonite, which is covered with lead. However, the lead covering is destroyed in a meteor strike, forcing Kara to be sent to Earth.

It is later revealed that Zor-El and Alura survived by entering the Survival Zone, a parallel continuum akin to the Phantom Zone. They are rescued by Supergirl and move to the bottle city of Kandor. In the New Krypton storyline, the two are killed by Reactron.

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. Her debut was delayed by her powers being stolen by a Kandorian villainess; during this period, she is adopted by Fred and Edna Danvers.

She attends Midvale High School as Linda 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, Secret Hearts (a play on the DC romance comic of the same name). 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. However, she has shunned serious commitments, placing 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 a member for a time. Like all Kryptonians, Supergirl is vulnerable to kryptonite. Streaky the Supercat, 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, a former centaur who was turned into a superpowered horse, is Supergirl's equine companion.

Post-Crisis versions

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.

Matrix

After the Post-Crisis reboot in the late 1980s, Supergirl's origin was completely rewritten and no longer was she Superman's cousin or even Kryptonian. In Superman (vol. 2) #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". She wears a miniskirted version of Superman's costume, similar to the Pre-Crisis Supergirl costume, but does not have Superman's exact powers. While she can fly and possesses super-strength (like Superman), she also has psychokinesis, shapeshifting, and invisibility.

New to the main DC universe, Matrix begins living with the Kents in Smallville. They give her the name "Mae" and treat her like their own daughter. Later, she starts a romance with the DC Universe's Lex Luthor (known as Lex Luthor II at the time), until she realizes Luthor's villainous nature when she finds out he has been cloning her. She leaves him to find her own way in the world with the support of his ex-wife, Elizabeth Perske. Supergirl then began serving for a time as a member of the Teen Titans. During her time as Supergirl, Matrix participated in many major events, including Panic in the Sky, Death and Return of Superman, and Zero Hour: Crisis in Time!.

Matrix/Linda Danvers

Beginning in September 1996, DC published Supergirl (vol. 4) written by Peter David. The 1996 Supergirl comic book 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 the Matrix merges with has the same name as the 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 the 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, the 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.

The angelic aspect of Supergirl eventually falls from grace, and Linda and the 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 one-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, the 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 (vol. 4) #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 timestream. 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, is set in a fictional city named Bete Noire, and 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."

Cir-El

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.

Supporting characters

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, 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 when, shortly before the radiation reached lethal levels, Zor-El projects them both into the 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.

Streaky – 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 – Pre-Crisis Supergirl's horse is a centaur accidentally cursed by Circe and transformed into a normal horse with superpowers. 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.

Other notable versions

Several different versions of Supergirl have appeared in continuity.

Power Girl (Kara Zor-L) – A version of Kara Zor-El from the parallel world Earth-Two, the cousin of Superman (Kal-L).

Laurel Gand (Andromeda) – Laurel Gand was the post-Crisis/Glorithverse replacement for the pre-Crisis Supergirl in the Legion of Super-Heroes after the latter was removed from the continuity following The Man of Steel reboot of Superman. Originally, Laurel is simply known by her given name. 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.

Alternate universe versions

In the final issue of DC Comics' 2006-07 year-long weekly series, 52 #52, it was revealed that a Multiverse system of 52 parallel universes, with each Earth being a different take on established DC Comics characters as featured in the mainstream continuity (designated as "New Earth") had come into existence. The Multiverse acts as a storytelling device that allows writers to introduce alternative versions of fictional characters, hypothesize "what if?" scenarios, revisit popular Elseworlds stories and allow these characters to interact with the mainstream continuity.

In 52 Week 52 (2007), the new Earth-2 is revealed and a newspaper headline declares that the Power Girl (and Superman) of this Earth are officially missing. On this world, Power Girl fights alongside Huntress (Helena Wayne), Obsidian, Robin, and others in the Justice Society Infinity. In Justice Society of America Annual #1, this world's native Power Girl re-emerges. In a subsequent reiteration of Earth-2 after the events of Flashpoint, Power Girl had a prior career on Earth-2 as that world's Supergirl before she and Earth-2's former Robin, Helena Wayne, were displaced onto Earth-0 after inadvertently entering a dimensional warp. They resided there for seven years until both returned.

Following 52 (2007), on the evil parallel universe of Earth-3, a mirror of the Earth-2 Kara Zor-L exists in the form of Ultragirl, first introduced in Countdown to Final Crisis #16 (2007). Unlike Ultraman, the Superman counterpart of Earth-3, this version of Supergirl is in fact vulnerable to kryptonite and not powered by it, implying she may be of Kryptonian origin. Following Flashpoint (2011), Earth-3 is an evil world once again most closely mirroring Earth-0. Ultraman is once again a Kryptonian, but a new Ultragirl was not introduced in this iteration. In the most recent incarnation of this universe, a new Ultragirl is introduced. Much like the main universe version, she is Ultraman's cousin, though she is a hero while Ultraman is a villain.

On Earth-10, Nazi Germany won World War II and that world's Superman, named Overman, is a part of the JL-Axis. That world's Supergirl was called Overgirl. She is first seen as a sketch made by exiled Monitor Nix Uotan in Final Crisis #2. She makes a full appearance in #3, where she crash lands in a burning heap on New Earth. There, she tells Renee Montoya, in German, that the sky is bleeding. She is not Overman's actual cousin, rather she is the only child who survived the horrible experiments the Nazis conducted when they tried to seed a human child with Overman's DNA. She has less than half of Overman's strength, speed, stamina and endurance, which is still considerable (however, this is subsequently modified after the events of Flashpoint impact the Multiverse-she is now a female clone of Overman, produced from his stem cells). She died in Final Crisis #7. In The Multiversity - Mastermen #1 (February 2015), Overman is still mourning her loss, six years after her death, as he opens a memorial to his fallen cousin in Metropolis. His lover Lena (Earth-10's Lana Lang) criticizes his prolonged mourning, as does the Valkyrie Brunnhilde (Earth-10's Wonder Woman).

In other media

Film

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.

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 Salkind Superman film series, to which it is connected by Marc McClure's character, Jimmy Olsen. Its plot, which connects more traditionally to the comics than Salkind's outline, 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 and no reference to the character was made in the subsequent Superman IV: The Quest for Peace.

In August 2018, a film centered around Kara Zor-El / Supergirl, was announced to be in development with Oren Uziel penning the script. The studio intends to hire a female director, with Reed Morano—who has expressed interest in the project—being its top choice. Filming was expected to start production in early 2020.

In February 2021, Sasha Calle was cast as Supergirl in The Flash (2023), directed by Andy Muschietti. In February 2023, it was confirmed that Calle would be portraying the Kara Zor-El version of the character.

In January 2024, Milly Alcock was cast in the role of Kara Zor-El / Supergirl, who debuted in Superman (2025) before her solo standalone 2026 film set in the DC Universe, which was loosely based on the Supergirl: Woman of Tomorrow (2021–22) miniseries by writer Tom King and artist Bilquis Evely.

Supergirl appears in media set in the Tomorrowverse, voiced by Meg Donnelly.

Television

In the seventh season (2007–2008) of the CW series 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 the ship had landed near 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.

A television series centered around the Kara Zor-El version of Supergirl, set in the shared universe Arrowverse, titled Supergirl starring Melissa Benoist as Kara Danvers, premiered on CBS on October 26, 2015, before later moving onto The CW on May 12, 2016. In the series, Kara was sent to Earth-38 to protect her cousin Kal-El although her pod got knocked off course and became stranded in the Phantom Zone for 24 years. Eventually, Kara crashes on Earth-38 where she is rescued by an adult Kal, who is now the iconic superhero "Superman". Superman leaves Kara in the care of the Danvers family who decides it best to hide her abilities from the world. Twelve years later, Kara is a reporter for Cat Co Worldwide Media. She eventually decides to reveal her powers to the world by saving her adoptive sister Alex Danvers from a near plane crash and is dubbed "Supergirl" by Cat Grant. With the help of Department of Extra-Normal Operations (D.E.O.) director Hank Henshaw who was later revealed as J'onn J'onzz / Martian Manhunter, her best friends Winn Schott and James Olsen / Guardian and her adopted sister Alex Danvers, Kara fights aliens and prisoners of fort rozz, led by her evil aunt Astra, and her husband non, who attempted to invade Earth. She is later joined by Lex Luthor's sister Lena, the Daxamite Mon-El, Querl Dox,(Brainiac-5) and Nia Nal / Dreamer in fighting enemies such as Mon-El's parents, the World Killers Reign, Red Daughter, alien activist Ben Lockwood / Agent Liberty the evil secret organisation Leviathan, and Nyxly in collaboration with Lex Luthor.

She is trained by 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 Brainiac's fate, Supergirl allies with Batman. 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.
