{{main|Multiverse (DC Comics)|List of DC Multiverse worlds}}
In the final issue of DC Comics' 2006-07 year-long weekly series, ''[[52 (comics)|52]]'' #52, it was revealed that a Multiverse system of [[The 52|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 (comics)|52]]'' Week 52 (2007), the new '''[[Earth-Two|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 (character)|Obsidian]], [[Robin (character)|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 (comics)|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 (comics)|52]]'' (2007), on the evil parallel universe of '''[[Earth-Three#New Multiverse|Earth-3]]{{Broken anchor|date=2024-12-08|bot=User:Cewbot/log/20201008/configuration|target_link=Earth-Three#New Multiverse|reason= The anchor (New Multiverse) [[Special:Diff/585906209|has been deleted]].}}''', 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 (DC Comics)|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 (comics)|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 [[The Monitors (comics)|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 (comics)|Flashpoint]] impact the Multiverse-she is now a female clone of Overman, produced from his [[stem cells]]).<ref>Multiversity: Mastermen (February 2015)</ref> She died in ''Final Crisis'' #7. In ''[[The Multiversity|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). 
*'''[[Earth-11]]''' is first featured in ''The Search for Ray Palmer - Superwoman/Batwoman'' (2007), and is a gender-reversed mirror of New Earth. While not featured in the pages of the comic itself, male Supergirl, or Power Girl counterparts may inhabit this Earth. The previous gender-reversed world featured in ''Superman/Batman'' #24 (2006) featured a male Kara Zor-El counterpart known as '''Superlad''' In the subsequent and current ''[[Multiversity]] Guidebook'' (January 2015), Power ''Man'' is described as existing on this Earth, although not depicted.
*In [[Mark Waid]] and [[Alex Ross]]' ''[[Kingdom Come (comic book)|Kingdom Come]]'' miniseries, '''Power Woman''' is Superman's cousin and a member of Superman's Justice League. This world is currently assigned the designation of '''[[Earth-22]]'''. However, a Supergirl appears with the Legion of Super-Heroes alongside Superboy in one panel, with dialogue implying they settled in the future permanently as the 21st-Century became difficult to live in. A brief line of dialogue from Superman implies that Argo City was never destroyed in this continuity, as he left some of the defeated Brainac’s circuitry there. According to Ross, a minor character in the story is the time-traveling daughter of Supergirl and Brainiac 5.
* In the [[Tangent Comics]] imprint (established as '''Earth-97''' prior to Infinite Crisis, now known as '''Earth-9''' post-''52''), '''Powergirl''' is a genetically engineered superheroine created by the Chinese government. Supergirl was an unsuccessful prototype.
* On [[New 52]] [[DC Multiverse]] '''Earth-29''', a [[Bizarro]]-Supergirl imperfect abiotic alternate version of the Kryptonian original exists. As with that world's [[Bizarro]]-Superman, it is uncertain whether they are native to Earth-29/Htrae, or arrived there from Krypton-29/Notpyrk.
*On [[New 52]] [[DC Multiverse]] '''Earth-38''', Supergirl is Kara Kent, the daughter of Superman and [[Lois Lane]] on an alternate Earth where Superman and Batman began their careers in the 1930s, married in the 1940s and had children in the 1950s. Unlike other iterations, she masks her actual identity by wearing a black wig as Supergirl, with her normal blonde hair as Kara. Unlike other iterations too, she is not a refugee evacuated from [[Krypton (comics)|Krypton]] or Argo City. Given prenatal exposure to [[gold kryptonite]] in utero, her brother Joel Kent is jealous of his sister and that leads him to eventually murder his mother Lois Lane and Kara/Supergirl during her wedding to Bruce Wayne Junior/Batman II.
*In ''Supergirl'' vol. 5 #32, Supergirl is shown 50 years in the future. She has a modified costume that is similar to her Pre-''Crisis'', original uniform. Here, she is seen fighting Dorlok, a man with a device that allows him to jump through time. In the end Supergirl, after contemplating using the device, destroys it and moves on.<ref>''Supergirl'' vol. 5 #32 (October 2008)</ref>
*In the ''[[Trinity (comic book)|Trinity]]'' series, reality is rewritten and Superman is removed from existence. In this alternative timeline, Kara Zor-El is known as "'''Interceptor'''" and has no knowledge of her Kryptonian heritage. Her ship was found by the Navy, but apparently no investigation took place.<ref>''Trinity'' #25 (November 19, 2008)</ref>
*In ''Legends of the DC Universe: Crisis on Infinite Earths'', Earth D is introduced as a previously unknown Pre-Crisis alternate Earth. In this reality, the heroes of the DC Universe are more ethnically diverse. Supergirl of Earth D is still named Kara, but she is married to Earth D's Superman. From Krypton's [[Vathlo Island]], she and her husband resemble Black humans.  Along with her husband and the other members of Earth D's Justice Alliance of America, she was killed during the Crisis as antimatter storms consumed their Earth.
*In the ''[[Ame-Comi]]'' imprint, both a Supergirl and a Power Girl exist together. In this universe, Supergirl is still Kara Zor-El, while Power Girl is actually the equivalent of Superman — her name is Kara Jor-El, and she is the daughter of Jor-El and cousin of Kara Zor-El. According to Supergirl, Jor-El and Zor-El destroyed Krypton intentionally as part of a failed attempt to destroy Brainiac, after sending both their Karas to Earth. Brainiac later reaches Earth and uses black kryptonite to turn Supergirl evil. Unusually for most depictions of Kryptonians, this Power Girl claims her powers do not come from the Sun.<ref>''Ame-Comi IV: Power Girl'' #1-3 and ''Ame-Comi V: Supergirl'' #1-3</ref>
*In the 2015 ''[[DC Bombshells]]'' iteration, Supergirl, Wonder Woman and Batwoman all exist in an alternate history version of World War II, independently of their male counterparts in the case of Batwoman and Supergirl<ref>{{cite web|url=http://www.dccomics.com/comics/dc-comics-bombshells-2015/dc-comics-bombshells-1 |title=BOMBSHELLS #1 |publisher=DC Comics |date=2015-08-12 |access-date=2015-08-28}}</ref> In this continuity, Kara Zor-El was born to Lara Lor-Van and Alura In-Ze was found in her spaceship by Russian farmers Varvara Dugina and Ipati Dugan, who raised her with their daughter, [[Stargirl (comics)|Kortni Dugiovna]].  The two sisters became best of friends and in their teens traveled to Moscow to join the legendary Night Witches, an all-female fighter squadron, but became Russian mascots after their powers were discovered. They abandon Russia when they find out the general intended to use them for his own destructive means and join the Bombshells team to aid in defeating the Nazis. When Brother Night turns into the Titan, Supergirl volunteers to sacrifice herself to defeat the monster, but Stargirl knocks her out and does it instead, saving Britain and devastating Supergirl in the process.<ref>''DC Bombshells''</ref> Kara becomes romantically involved with Lois Lane in this universe.
*The 2016 miniseries ''Supergirl: Being Super'' written by [[Mariko Tamaki]] and penciled by [[Joëlle Jones]] is a coming-of-age take on Supergirl's origins,<ref>{{cite web | url=http://www.syfy.com/syfywire/inside-supergirl-being-super-with-writer-mariko-tamaki | archive-url=https://web.archive.org/web/20180624083859/http://www.syfy.com/syfywire/inside-supergirl-being-super-with-writer-mariko-tamaki | archive-date=2018-06-24 | title=Inside Supergirl: Being Super with writer Mariko Tamaki Inside Supergirl: Being Super with writer Mariko Tamaki &#124; SYFY WIRE | work=SYFY WIRE | date=May 28, 2018 | last1=Estrella | first1=Ernie }}</ref> depicting 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 astonishing super-human abilities, which she keeps a secret even from her closest friends.
*In the world of ''Gotham City Garage'', Kara Zor-El was adopted by [[Jim Gordon (character)|James Gordon]] and becomes '''Kara Gordon''', Barbara's adoptive sister and a ridealong technician.<ref>{{cite web | url=https://www.monkeysfightingrobots.co/new-dc-series-gotham-city-garage/ | title=The Women of DC are Anti-Fascist Bikers in 'Gotham City Garage' | date=July 20, 2017 }}</ref>
*In [[Frank Miller (comics)|Frank Miller]]'s ''[[Batman: The Dark Knight Strikes Again]]'', Superman and Wonder Woman hide their daughter '''Lara''' from the world her entire life, but she later becomes important to the defeat of Lex Luthor and Brainiac, the story's antagonists. Lara possesses some of Wonder Woman's powers, benefiting from both a Kryptonian and an Amazonian heritage as that universe's '''Supergirl'''.
*In [[Kurt Busiek]]'s ''[[Superman: Secret Identity]]'' miniseries, which depicts a [[Clark Kent]] who lives in the real world, Lois gives birth to two girls who grow up to manifest their father's powers and adopt variations on his costume.<ref>''Superman: Secret Identity'' #4</ref>
*''[[Elseworld's Finest: Supergirl & Batgirl]]'' depicts a [[Barbara Gordon]]/Kara Zor-El team in a world without their male counterparts. In another story that took place in this reality as seen in ''Superboy'' (vol. 3) #61, there is a female equivalent to the [[Conner Kent]] Superboy named Supergrrl. This Supergrrl is a clone of Supergirl, only aged at sixteen or so, who was created by that world's Lex Luthor.
*''Supergirl: Wings'' reworks the Earth-born angel storyline with [[Zauriel]] as her companion; in it, Linda's guardian angel is Matrix, whose cynical view of her charge may lead to her fall.<ref>''Supergirl: Wings'' #1</ref>
*In the ''[[Superman/Aliens]]'' [[crossover (comics)|crossover]] limited series, published in 1995 by DC Comics and [[Dark Horse Comics]], Superman discovers a domed city on an asteroid, not unlike the Argo City of the pre-''Crisis'' Supergirl's origins, that is infested with the [[xenomorph (Alien)|xenomorph]]s. Superman befriends the sole survivor, a plucky 16-year-old girl named Kara. The story reveals that Kara is not Superman's cousin, and that the colony is not Kryptonian, but is instead part of a world whose culture and religion were strongly influenced by Krypton.
*In ''[[Superman & Batman: Generations]]'', Superman's young daughter, '''Kara Kent''', takes up the identity of Supergirl and forms a new Justice League with Bruce Wayne Jr., [[Wally West]], and Stephanie Trevor. As they grow up, Kara and Bruce Jr. fall in love, becoming a couple in "civilian" life and a crime-fighting duo as Superwoman and Batman. The two eventually marry, but their happiness barely lasts beyond the ceremony when Kara's elder brother Joel attacks the wedding reception. The jealous Joel, who grew up without superpowers due to exposure to [[gold kryptonite]] as a fetus, was manipulated by [[Lex Luthor]] into striking against his family with artificial superpowers bestowed by a formula Luthor created; he leads Kara away from the reception and kills her in a rage, but dies himself from the deliberately imperfect serum that Luthor gave him.
:In ''Superman & Batman: Generations 3'', Knightwing (Joel's son Clark, whose Kryptonian genes were activated by a perfected version of Luthor's serum) and his wife have twin daughters, Lois and Lara, who take the heroic identities of '''Supergirl Red / Supergirl Blue'''. Supergirl Blue gives up her powers in the 25th century so she can age normally, but uses Luthor's serum in the 26th century to restore them. Supergirl Red is killed the same century, leaving her sister as the last Supergirl. Supergirl Blue dies in the 30th century. When [[Darkseid]] is destroyed, she is erased from the timeline.
*In ''[[JLA: Created Equal]]'', Linda Danvers, fifteen years after the Fall (a population destroying plague that killed all males), changes her name to '''Superwoman'''.<ref>''JLA: Created Equal'' #1</ref>
*In ''[[JLA: Act of God]]'', Linda Danvers is one of many metahumans who loses her powers due to the Black Light event that strips the entire metahuman community powerless. However, she, along with the Martian Manhunter, Aquaman and the Flash, trains with Batman and his associates so they may still be heroes. Changing her name to '''Justice''', Linda and the others form the "Phoenix Group".
* In ''Superman/Gen<sup>13</sup>'', Caitlin Fairchild of [[Gen¹³|Gen<sup>13</sup>]] had received a bump on the head and suffered amnesia. When she awoke, she found Superman's cape draped over her and assumed that, with her super powers, she was Supergirl. She believed that she could not fly due to exposure to red kryptonite which, at the time, was only considered an urban legend. After going through multiple Supergirl outfits and generally causing more havoc than good, she was found by the other Gen<sup>13</sup>s and Superman when the real Supergirl knocked her out. When Caitlin awoke, she regained her memory.
* Supergirl is shown in ''[[Justice (DC Comics)|Justice]]'' with other heroes helping the Justice League in their confrontation against the [[Legion of Doom]]. Since the continuity resembles the Silver Age and she is wearing a variation of her 70s era costume, this Supergirl is most likely Kara Zor-El.
* Supergirl made a brief appearance in ''[[JLA: Another Nail]]'' when all time periods meld together. She is presumably Kara Zor-El, since she is wearing a costume identical to her first appearance in ''Action Comics'' #252.
*Kara Zor-El appears in the six-issue mini series ''Supergirl: Cosmic Adventures in the 8th Grade''. The series features elements from all aspects of Supergirl continuity, but is written with a more tongue-in-cheek tone for young readers. In this series, Kara is designed as a typical teenager from Krypton's moon, Argo, who (unintentionally) ends up on Earth and meets up with her cousin, Superman.  With his help, Kara is given a cover identity as Linda Lee and is enrolled in school. Over the course of the series, Kara befriends a local student named Lena Thorul (who, ironically, is actually Lex Luthor's sister (her last name is an anagram of “Luthor”)), deals with her own "Bizarro" self, Belinda Zee and ultimately gets drawn into the reality-conquering schemes of [[Mr. Mxyzptlk]].
**An alternative version of Kara is accidentally created when she gains time travel powers in order to prevent a meteor from hitting the school. This version of Kara is called '''Supragirl''' (after wanting to be called "Andromeda").
*Supergirl appears in the ''[[Tiny Titans]]'' comic book. Due to her pets Krypto, Streaky, Comet and Beppo appearing, this Supergirl is probably Kara Zor-El. She is portrayed as giggly and kind. She is shown to fly everywhere giving her character a sense of innocence. She is very smart, gaining A's and 'super' comments from her supervillain teachers. Batgirl and Robin are shown as two of her closest friends in the book; they all attend pet club together. Batgirl and Supergirl spend time together without the other Titans by having picnics. 
*Supergirl appears in the comic crossover ''Justice League vs. Godzilla vs. Kong'' in which and the Justice League deals with [[Godzilla]], [[King Kong]] and other monsters from the [[Monsterverse]] unleashed into the DC Universe. Supergirl is brainwashed by Grodd but later breaks where she helps defeat an rebuilt [[Mechagodzilla]].
