->'''AKA:''' Linda Lee Danvers/Kara Zor-El

Superman's younger cousin, Kara Zor-El survived the destruction of Krypton thanks to her father, Zor-El, putting a protective dome around Argo City that sent it hurtling into space. However, the citizens of Argo were quickly dying from Kryptonite poisoning, so before they died, Zor-El and his wife Alura placed their daughter in a spaceship and sent her to Earth where she could flourish under Superman's guidance.

At first acting as Superman's "secret weapon" while she developed her powers in secret under the assumed name of Linda Lee Danvers, Supergirl eventually burst onto the superhero scene as the Maid of Might. She had a long and illustrious career fighting evil--she became best friends with fellow superheroine ComicBook/{{Batgirl}} I (Barbara), became a member of the ComicBook/{{Legion of Super-Heroes}} (and struck up a romance with Brainiac 5), and even saved her parents from the past and helped them found New Krypton on the distant planet of Rokyn. She gained her own sidekicks in the form of Streaky the Super-Cat and Comet the Super-Horse.

In the end, Kara died a hero. When the Anti-Monitor attempted to destroy TheMultiverse, she sacrificed her own life so that her cousin might live. In so doing, however, she severely set back the Anti-Monitor's plans, making victory possible for the heroes of the surviving Earths. The greatest tragedy of all, however, was that with the destruction of the Multiverse and changes to the timestream, Kara was erased from history, and no one at all remembered her heroic life and death.
* ActionGirl
* AlliterativeName: Linda Lee
* BattleCouple: With Brainiac 5.
* BrainsAndBrawn: With Brainiac 5. She's the muscle, he's the intellect.
* BreakTheCutie
* BroughtDownToNormal: MadScientist Lesla-Lar took away Kara's powers as part of a scheme to replace her. While in her powerless state, Kara finally found adoptive parents. She nearly abandoned her career as Supergirl, until Mr. Mxyzptlk granted her all the abilities of Superman, plus a (temporary) invulnerability to green kryptonite.
* TheCape
* TheChick
* ComicBookTime: Slowly averted. When she first appeared, she was a young girl, early teens at most. In her final appearances she was a young woman.
* DistaffCounterpart
* DyingMomentOfAwesome: Lays an absolute beatdown on the Antimonitor before being taken out by a lucky shot. One of the most {{badass}} feats ever achieved by any comic book character, ever.
* GirlishPigtails: Linda wore her hair like this when she lived in Midvale Orphanage.
* GuardianAngel: [[spoiler:After her death and subsequent erasure from the DCU, Kara seemed to have taken up this role. The first time she appeared to a despondent Deadman during a Christmas special, the second time she appeared towards Linda Danvers. However, both times the person in question was only identified as Kara and not Supergirl.]]
* HeroicSacrifice
* InterspeciesRomance: With [[ComicBook/{{Legion of Super-Heroes}} Brainiac 5]].

[[folder:Supergirl I (Post-Crisis)]]
->'''AKA:''' Matrix

A purple shape-shifting creature from a PocketDimension, she was created by that universe's ComicBook/LexLuthor and patterned after the [[{{Superman}} New Earth Superman]]. When that universe was attacked by Phantom Zone escapees that she was no match for, Pocket Universe Lex sent Matrix to recruit New Earth Superman, but was too late to save the universe. Matrix was later taken in by Superman to be raised by Supes' adoptive parents and eventually became the first PostCrisis Supergirl. She later accidentally fused with Linda Danvers below, and made her the next Supergirl.
* ArtificialHuman
* ShapeShifter
* FlyingBrick: Even more so than Superman.
* NaiveNewcomer: So naive she shacked up with [[ComicBook/LexLuthor LEX LUTHOR]]!
* PutOnABus: Same as Linda below.
* {{Invisibility}}: One of her lesser-used powers.
* {{Telekinesis}}: The source of most of her powers.
* TinMan: Part of what drove her was her perceived lack of humanity. After Matrix merged with Linda Danvers, she was given the opportunity to live as a regular human. Although, most everyone who knew it really was Matrix stated she had more of a soul than Linda did up to that point.
* WomanScorned: When she finds out Lex is evil.

[[folder:Supergirl II (Post-Crisis)]]
->'''AKA:''' Linda Lee Danvers

* TheAtoner: For her sins as a cultist and several other mistakes.
* BareYourMidriff: Her second costume. Lampshaded in the comic when a cop called it her "Britney Spares" outfit.
* CorruptTheCutie: What Buzz did to her, though she admits everything she did was of her own free will.
* DeadpanSnarker
* FallenAngel
* HappilyMarried: Spent five years married to the Superman of Earth-One after switching places with Kara.
* HeelFaceRevolvingDoor
* MamaBear: Was willing to let the universe fall apart if her daughter wasn't spared from being retconned.
* MythologyGag: Pre-Crisis, Linda Danvers was Kara Zor-El's secret identity and the Danvers, Fred and Edna, were her adoptive parents. Post-Crisis, Linda and Kara Zor-El are two separate people, and the Danvers, Fred and Sylvia, are Linda's biological parents.
* PlayingWithFire
* PutOnABus: After her series ended, Linda pretty much dropped out of TheDCU. She hasn't been consigned to CanonDiscontinuity, but she's barely ever mentioned anymore, either.
* SecretIdentity: As Linda, though by the end of the series, pretty much everyone knows.
* ShoutOut / CanonImmigrant: Her second costume is based on {{DCAU}} Supergirl.

[[folder:Supergirl III (Post-Crisis)]]
->'''AKA:''' Cir-El

* CanonDiscontinuity: She was [[CosmicRetcon erased from history]].
** To add insult to injury, she had ''erased herself'', was brought back to do a major crossover event, then was subsequently sent away ''again'' right afterward.
* DarkerAndEdgier
* KidFromTheFuture: She claimed to be Lois and Clark's kid. She wasn't.

[[folder:Supergirl IV (Post-Crisis)]]
->'''AKA:''' Linda Lang/Kara Zor-El

Superman's older cousin, Kara Zor-El survived the destruction of Krypton thanks to her father, Zor-El, putting a protective force-field around Argo City that sent it hurtling into space. However, the citizens of Argo came under attack from the evil alien Brainiac, so before they were conquered, Zor-El and his wife Alura placed their daughter in a spaceship and sent her to Earth where she would care for her young cousin Kal-El.

Arriving on Earth, Kara found that she had been in suspended animation for decades and her cousin was now an adult while she was still a teenager. Adopting her cousin's mantle as Supergirl, she trained under both Franchise/{{Batman}} and Franchise/WonderWoman, and eventually moved in with Lana Lang, pretending to be her niece. Throughout her career, she would battle inner demons which sometimes manifested as a violent, blackclad Supergirl (hereafter referred to as Dark!Kara).
* AbusiveParents: In her first origin, her father made her kill her classmates, sent her to kill her cousin and stood around with her while she was naked. WHY. See {{Retcon}} below.
** In contrast to the previous origin, it's her KnightTemplar mother who verges on this at points after her father's death. She never goes farther than being verbally abusive to Kara, though. Her father, on the other hand, was a doting NiceGuy.
* ActionGirl
* AlliterativeName: Linda Lang
* AlternateSelf: She and Power Girl are this to one another, which leaves Kara very weirded out about the possibility of meeting her.
* AntiHero: Before CharacterDevelopment set in. She eventually dropped the "anti" part and settled on being a hero.
* {{Archenemy}}: With Reactron, who killed her father and mother and blew up her planet.
* BadassCape
* BashBrothers: With Wonder Girl. She and Superman and she and Dick Grayson are a platonic, two-gender variant.
* BareYourMidriff
* BattleCouple: With Brainiac 5.
* BelligerentSexualTension: With Brainiac 5, whose attitude and frosty demeanour rub her the wrong way.
* BlondesAreEvil: As Dark!Kara.
* BrainsAndBrawn: With Brainiac 5. She's the brawn, he's the brains.
* CallingTheOldManOut: Does this to her mother near the end of "New Krypton" after she finds her torturing Reactron.
* TheCape: For all her problems, Kara was headed strongly in this direction by the time of the ''New 52'' reboot. She'd put the past behind her, adopted Superman's attitude towards dealing with problems, built strong friendships with other heroes, and was well on her way to being the same sort of paragon as her cousin.
* ClarkKenting: Used glasses and a different haircut to become Linda Lang.
* DaddyIssues[=/=]MommyIssues: Originally she was shown to have serious issues with her dad. These were eventually retconned out and replaced with a strained relationship with her EvilMatriarch KnightTemplar mother.
* DaddysGirl: Once all the retcons were hashed out.
* DarkActionGirl: Dark!Kara who was originally a far more capable fighter than the actual Kara.
* DarkerAndEdgier: She got over it.
* DefeatMeansFriendship: With Bizarrogirl
* DistaffCounterpart: To the Post-Crisis Superman.
* EmoTeen: Had shades of this early on in her career, though not without reason. If your planet was destroyed, you were marooned on an alien world, and the person you thought you were going to be protecting was suddenly much older and more experienced than you, you'd have issues too.
* EnemyWithout: Luthor exposes Kara to Black Kryptonite, causing a version of Dark!Kara to emerge from her body. It embodies all of her negative emotions and proceeds to go on a rampage.
* EvilCostumeSwitch: The black costume sported by Dark!Kara.
* FishOutOfWater: One of the defining traits of this interpretation of the character. Unlike her more famous cousin, who left Krypton when he was too young to remember it, Kara spent her formative years growing up in Kryptonian society before she was sent to Earth as a teenager. Understandably, she has a harder time adjusting to life on Earth than Kal-El ever did, as she still considers herself a Kryptonian at heart.
* GroinAttack: What she did to a stalker; fortunately, he was from Apokolips so it ONLY hurt a whole lot.
* HappilyAdopted: By Lana Lang, whose niece she is pretending to be.
* HotBlooded: At least when compared to her cousin. Kara tends to charge into situations without thinking, which nearly got her killed against Luthor.
* InterspeciesRomance: Any relationship she has with a non-Kryptonian is this by definition. Most notably with Brainiac 5.
* ItsPersonal: With Reactron after he kills her father. It doesn't end well, and he eventually blows up her mother and almost every surviving member of her race. She also takes her enmity with Doomsday this way, knowing that he once killed her cousin.
* LikeBrotherAndSister: She and Dick Grayson (Robin I/Nightwing/Batman III) have this vibe, with him considering her a little sister.
* MinidressOfPower
* MsFanservice: Her costume is basically a cheerleader outfit.
* NoSocialSkills: Angry, emotionally damaged, and unfamiliar with Earth's customs, Kara gets herself in a lot of trouble during her first few years on Earth.
* OddCouple: Energetic former EmoTeen Kara and [[TheSpock frosty]], intellectual Brainiac 5.
* OlderThanTheyLook: Kara's actually Superman's older cousin, and is somewhere in her late twenties/early thirties. Cryogenic sleep, however, has kept her a teenager mentally and physically.
* PantyShot: Though her skirt might have been a MagicSkirt considering that is covered anything at all most of the time, when it really physically couldn't. When Jamal Igle took over art duties, he ''finally'' gave her some shorts.
* PluckyGirl: After CharacterDevelopment.
* ReplacementGoldfish: After Superboy's death, [[HeterosexualLifePartners Cassie develops a close friendship with Kara.]] Later on, she decides to cut off ties with Kara specifically because of this trope. [[WhatTheHellHero Kara didn't take it well.]]
* {{Retcon}}: That thing about her father raising her as an assassin and having her stand around naked all the time? It was just a hallucination she experienced due to latent Kryptonite poisoning.
* RomanticTwoGirlFriendship: With Wonder Girl in the ComicBook/TeenTitans. They nearly kissed in ''Supergirl: Identity''.
* SaveTheVillain: Actually tries to save Reactron from being tortured by her mother.
* SavvyGuyEnergeticGirl: The energetic girl to Brainiac 5's savvy guy.
* SecretIdentity: Linda Lang.
* {{Stripperiffic}}: A major point of complaint in the pre-Igle stories was just how scanty her costume was as drawn by most artists, especially given that it was supposedly Martha Kent's idea of an appropriate costume for her foster-son's teenage cousin. This was thankfully toned down later on.
* SuperpowerLottery: Including...
** EyeBeams
** FlyingBrick
** FlyingFirepower
** NighInvulnerability
** SuperSenses
** SuperSpeed
** SuperStrength
** XRayVision
* SuperpoweredEvilSide: Dark!Kara, who is released under the influence of Darkseid, Black K, or similar events. Each time, however, she gets a little better and easier to control; in her last appearance, she's just a brat, rather than a homicidal maniac.
* SurvivorsGuilt: Struggles with this after ''New Krypton'', resulting in the remergence of Dark!Kara, and a psychosomatic illness that nearly kills her. Dr. Fate helps her overcome it during the events of ''Reign of Doomsday''.
* TheTease: She liked taunting Captain Boomerang Jr. about his obvious crush on her. She eased up on it when she realized it was a real JerkAss thing to do.
* ThereAreNoTherapists: Averted. It's a talk with Kent Nelson (Dr. Fate) a psychiatrist that helps Kara get over her trauma and survivor's guilt during ''Reign of Doomsday''.
* TookALevelInBadass: Over the course of her series.
* UnderestimatingBadassery: People tend to this to Kara on account of her age and lack of experience. Kara herself does this to ComicBook/LexLuthor early in her career, and to Reactron in ''New Krypton'', with disastrous results both times.
* UnskilledButStrong: Early on this was a serious problem. Her lack of experience and general inability to use her powers to her fullest nearly got her killed during a confrontation with ComicBook/LexLuthor.

->'''AKA:''' Ariella Kent

The daughter of Linda Danvers and an alternate ''SilverAge'' Superman. After her parents were erased by the ''Comicbook/CrisisOnInfiniteEarths'' and Comicbook/TheSpectre's interference, Ariella was left to wander space and time on her own.
* ComboPlatterPowers
* {{Cloudcuckoolander}}
* DoesNotKnowHerOwnStrength
* TheDreaded
* EnfanteTerrible: How everyone else views her, as this six-year-old is too naive and innocent to realize that she destroys everything around her whenever she moves.
* GooGooGodlike: Comes with being the daughter of Linda Danvers and an alternate ''SilverAge'' Superman. She is most likely second only to [[InfiniteCrisis Superboy-Prime]] when it comes to raw power.

An alternate version of Kara from the all-ages comic, ''Supergirl: Cosmic Adventures in the 8th Grade''.
* AlliterativeName: Linda Lee
* BreakTheCutie: Mxy tries this. It doesn't work. She's Supergirl, darnit!
* CloudCuckoolander: With her constant fantasies of "Moon Supergirl".
* EvilTwin and EvilCounterpart: Belinda.
* NaiveNewcomer
* FriendlyEnemy: With Lena Luthor.
* PluckyGirl: Her unending optimism despite all odds infuriate Mxy to no end.
* SecretIdentity: Linda.

[[folder:Supergirl (New 52)]]
->'''AKA:''' Kara Zor-El

Superman's older cousin, Kara Zor-El survived the destruction of Krypton thanks to her father, Zor-El, who put her in a spaceship to save his only daughter.
* AdaptationalAngstUpgrade: You kinda expect her to be more easy-going, especially if you're most familiar with the Kara from WesternAnimation/SupermanTheAnimatedSeries as many casual fans are. So the fact that she can [[spoiler: become so infuriated that a Red Lantern ring is draw to her is unusual.]]
** As of issue 34, she appears to have got over it.
* AliensSpeakingEnglish: Averted and later played straight: Kara could only speak Kryptonian at first and was taking English lessons from Siobhan. When she met fellow kryptonian [[ComicBook/HelOnEarth H'el]] in Issue #14, he gave her the ability to understand and speak English perfectly.
* AlternateSelf: Supergirl and ComicBook/PowerGirl are the exact same person from different universes. Power Girl is ''very'' reluctant to meet her mainstream universe self at first partly because she is worried the universe would explode if they actually touched. When they finally meet in ''Supergirl'' #19, [[spoiler: the universe is fine, the two Karas psychically bond, kick butt together and the only snag is Supergirl's fortress AI mistaking Supergirl for a clone and trying to destroy her.]]
* CharacterDevelopment: the entire series is largely about Kara confronting her demons, getting used to her powers and new circumstances and doing a lot of sorely needed growing up. And, in 34 issues, she goes from scared, angry, but ultimately well meaning teenager to wise, kindly heroine who Superman entrusts with the protection of Earth while he shakes off the Doomsday virus.
* FantasticRacism: hates clones, believing that they inevitably turn evil, which proves unfortunate for Superboy, whose very existence revolts her - though it could be argued that she pities him more than anything else. This turns out to be a learned prejudice, one held by Kryptonians at large due to the Kryptonian [[TurnedAgainstTheirMasters Clone Revolt]]. The events of ''H'el on Earth'' cause her to re-examine this prejudice and unlearn it, and when she runs into Superboy again in issue 38 and he's attacked, she immediately jumps to his defence.
* {{Flanderization}}: Past versions of her were merely headstrong and a little HotBlooded. Here, her anger is an actual plot point [[spoiler:in the Red Daughter of Krypton arc]].
** Superboy explicitly notes that the Kara he met on Krypton during the time travelling battle against H'el was much nicer than the version that he encountered on Earth. He quickly [[CaptainObvious and logically]] concludes that the fact that she lost her entire world soured her just a tiny bit.
** As of issue 34, she seems to be calmer, wiser and kinder, having got the rage out of her system and been asked by Superman to protect Earth in his stead.
* TheBigGal: Her combination of great physical power and hotheadedness tend to push her into this role on a team, notably as a member of the Justice League United.
* FlyingBrick
* HeroWithBadPublicity: Confused and frightened, she fought Superman when they first met; which didn't exactly make the public like her.
** She yo-yo's back and forth on this - some remember her fight with the Worldkillers in New York and praise her as a hero. Others... not so much.
* HowDoIShotWeb: Supergirl had a hard time adjusting to her new-found powers when she landed on Earth.
* LeotardOfPower: Unlike previous incarnations, Supergirl's outfit in the ComicBook/{{New 52}} lacks a skirt.
* MadeOfIndestructium: Her outfit and cape.
* MyBloodRunsHot: From Supergirl 28 through Supergirl 33, with the same [[spoiler: Red Lanterns issues, Kara is the recipient of a Red Lantern Ring, while still keeping her Kryptonian abilities.]]
* MostCommonSuperpower: Averted. She has a rather modest bust to match her slim teenage physique.
* NakedOnRevival: In issue 23, her body was dissolved using a machine, leaving only her clothes in a pile. In issue 24, her body was restored by the same machine, but she had to put her clothes on manually.
* NiceGirl: once you get past the angst and anger issues, both of which she outgrows, she is, in her own way, every bit as sweet and kind as her cousin.
* NoSocialSkills: Unlike Superman, she arrives on Earth as a teenager instead of being raised amongst humans as a young child. As a result she is unfamiliar to Earth customs and can only speak Kryptonian for the first dozen or so issues.
** In Issue #8, Kara meets Siobhan, who [[{{Omniglot}} can speak any language]] after hearing a few words of a language. She's able to communicate with Kara and helps her adjust to life on Earth.
** It gets ''really'' showcased in Issue #11 when she goes on a date with Siobhan's brother. She walks in on him while he was getting dressed and took a pizza without paying for it.
* OlderThanTheyLook: Kara was a teenager when her father put her in a spaceship. The ship put her body in stasis and landed on Earth years later; which is why her baby cousin [[Franchise/{{Superman}} Kal-El]] looks older than her.
* PerpetualFrowner: Until issue 34, at least, you could count the number of times she's smiled in the New 52 on one hand. Now, she smiles a bit more.
* RageBreakingPoint: She's been through hard times during her time on Earth, leading to a lot of built up rage. Her fight with Lobo is the final straw, as his attempt to manipulate her causes her to [[NoHoldsBarredBeatdown thrash him]]. [[spoiler:Her rage is enough to attract a Red Lantern ring]].
* SmarterThanYouLook: Her hot temper, teenage naivete and lack of fighting finesse leads a lot of enemies to consider her simply DumbMuscle. In fact she ''does'' have brains - as witnessed by her outwitting Tycho and Sanctuary.
* SuperpowerLottery: Since she's a Kryptonian like Superman, she has the same powers as him.
** ActionBomb: Can release the solar energy within her as an explosion without harming herself. Oddly, only she has been shown to use this ability. Either Superman doesn't have it or at least doesn't know he can.
** EyeBeams: Her heat vision.
** {{Flight}}
** TheNeedless: As long as she stays charged with solar radiation, Kara doesn't need to eat, sleep, or breathe.
** NighInvulnerability
** SuperSpeed
** SuperStrength
* TeethClenchedTeamwork: every time she worked with Superboy, at least at first, due to Kryptonian FantasticRacism towards clones. The events of ''H'el on Earth'' seem to have changed her opinion of him and clones in general, and when they run into each other again in issue 38, she instantly jumps to his defence, facing down a group of powerful heavy hitters, more skilled and experienced than her, and telling them that if they want Superboy, they're going to have to [[GoThroughMe go through her.]]
* TraumaCongaLine: she woke up with missing memories, on an alien world, all alone and was promptly attacked by men in PoweredArmour. Shortly after that, she encountered a grown man claiming to be her baby cousin. Shortly after ''that'' she's lured in and kidnapped by an amoral trillionaire who wants the secrets of Kryptonian technology, poisoned with Kryptonite, and [[BrokenPedestal then the]] [[MookFaceTurn guy who rescues her]] is murdered in cold blood. After she gets away from all of that, she's utterly alone in an alien world, then finds a link to her very dead home. She follows it... and finds that her home is basically a ghost city, whereupon she is beaten up by a Kryptonian supersoldier called a Worldkiller. After escaping all that, she has to fight four Worldkillers, then, exhausted, is promptly attacked by the US Army and Police, with only one human standing up for her (and is, conveniently, an {{Omniglot}}). Said human befriends her, then [[spoiler: turns out to be [[SuperpoweredEvilSide the Silver Banshee,]] who is being hunted down by her father, the Black Banshee]]. After briefly being absorbed, body and soul, she fights her way out. Then she gets attacked again, while on a date. Oh, and the first man she falls in love with is H'el, who's manipulating her, using her affection for him to trick her into a brief FaceHeelTurn. Then, in defeating H'el, she's poisoned with Kryptonite. ''Again''. And then there's the revelation that [[spoiler: her father was experimenting on her]]. No wonder the poor girl has problems.
* TomboyishSidetails: As a small child.
* UnderwaterBase: In issue #13, she gains the Sanctuary: a Kryptonian base at the bottom of the ocean. It's basically her version of Superman's Fortress of Solitude.
** AIIsACrapshoot: Sanctuary is programmed to eradicate any Kryptonian double in her presence. When Supergirl and her Earth 2 counterpart Power Girl enter Sanctuary in issue #19, it deems Supergirl the double and tries to eliminate her. [[spoiler:The two Karas must destroy Sanctuary to save Supergirl. However, the A.I. survives in a robot body; hellbent on destroying Supergirl]].
* UnskilledButStrong: She may be as powerful as Superman, but she doesn't have his years of experience or combat skills. Her lack of skill is remarked upon during her fight with Wonder Woman.
* WorkingThroughTheCold: The events of ''ComicBook/HelOnEarth'' left her with kryptonite poisoning. Despite this she can still fight at full strength. It eventually gets to her; leading to her capture by Cyborg Superman. The kryptonite poisoning is removed when Cyborg Superman dissolves her body and extracts the kryptonite before restoring her.
* WhenSheSmiles: It's rare, but it is absolutely adorable. Becomes more common after the [[spoiler:Red Daughter of Krypton]] arc allows her to let go of most of her rage.
* YouCantGoHomeAgain: She really wants to go back home to Krypton, but can't since Krypton was destroyed. [[spoiler:This motivates her temporary FaceHeelTurn in ''ComicBook/HelOnEarth''.]] Superman's perceived indifference towards Krypton and its fate is one of the causes of friction between them.


[[folder:Bizarrogirl (Pre-Crisis & Post-Crisis)]]
There were two different Bizarro versions of Supergirl in Pre-Crisis continuity. The first was pretty much just a GenderFlip version of the regular Bizarro in body and mind and died in her first appearance but the second was a little different. The second Bizarrogirl was created when the Bizarros used a Duplication Machine on the real Supergirl who at the time had been left with a monstorous appearance by a vindictive alien prince. The result was a Bizarro girl with the beautiful looks the real Supergirl (normally) posessed but the mind of a Bizarro, effectively making her a BrainlessBeauty.

The Bizarro counterpart of Post-Crisis Kara, Bizarrogirl, was rocketed to Earth by Bizarro #1 when he believed that the Godship was going to destroy Bizarroworld. Here she hurt or killed several people, before being defeated by Supergirl; Kara retunred Bizarrogirl to Bizarroworld, befriending her in the process.
* AntiHero: Manages to achieve this status near the end of her arc.
* BadIsGoodAndGoodIsBad: As is the usual case for Bizarros. Bizarrogirl is a little smarter than most, however, and is eventually able to get her head around the notion that killing people is bad.
* BareYourMidriff: Averted, with her costume being closer to that of the Pre-Crisis Supergirl than the Post-Crisis one.
* BewareTheSillyOnes: Kara learns this the hard way. So does the Godship.
* BlondesAreEvil
* BrainlessBeauty: The second Pre-Crisis Bizarrogirl had Supergirl's looks but the usual Bizarro dimwittedness.
* BreathWeapon: Breathes fire.
* BroughtToYouByTheLetterS
* ChestInsignia
* CowardlyLion: Admits to being terrified of the Godship, yet still does a bang up job fighting it after she grows a spine.
* DefeatMeansFriendship: With Supergirl
* DumbMuscle: Though not to the same degree as the usual Bizarros. Bizarrogirl is capable of learning from her mistakes and doesn't get everything backwards.
* EvenEvilHasLovedOnes: Clearly cares about Bizarro #1.
* EvilKnockoff: Of Supergirl, whom she believes to be the real Bizarro.
* EyeBeams: Like Bizarro #1 she can fire [[AnIcePerson freezing beams]] from her eyes. She also has [[TakenForGranite stone vision]] to contrast Supergirl's X-Ray vision, something that no other Bizarro has.
* FlyingBrick
* GrewASpine: After a talking to from Supergirl.
* HeelFaceTurn: Has a better understanding of good, evil, life, and death at the end of her arc, and tries to become a hero (or as much of one as a Bizarro can be).
* HeroWithAnFInGood: She's more genuinely stupid than suffering from the usual Bizarro backwards logic. As she grows to understand other people she becomes more genuinely heroic.
* HulkSpeak
* ImAHumanitarian: Threatens to eat Jimmy, though she may not understand the implications of the threat.
* NighInvulnerability
* NotSoDifferent: She and Kara have a lot more in common than Superman and Bizarro #1 do.
* ObliviouslyEvil: Has no idea that she's really hurting people, and is horrified once the Godship's attack forces her to understand what death is really about.
* OddballDoppelganger
* PrecociousCrush: On Bizarro!Luthor, much to the real Kara's disgust.
* PsychopathicWomanchild: Has the intellect and personality of a scared, angry little girl.
* RedEyesTakeWarning: Her eyes are naturally red.
* SuperSenses
* SuperSpeed
* SuperStrength

[[folder:Buzz (Post-Crisis)]]

[[folder:Cyborg Superman (New 52)]]

After ''ComicBook/HelOnEarth'' and [[spoiler:destroying the Sanctuary]], Supergirl has had enough of Earth and goes off-planet to find a new home. Luckily for her, she finds a much more generous planet named I'noxia that hails her as a hero when she saves them from danger. Their technology can even make robotic replicas of people from her memories; making the place a paradise... or so it seems. It is there she meets Cyborg Superman: a mysterious cybernetic being that looks very much like her cousin. He tells her that he's behind all this and can give her everything she desires on the planet. There's just one little fee: he wants her flesh to replace his cybernetic parts.

For pre-ComicBook/{{New 52}} Cyborg Superman, see [[Characters/SupermanVillains Superman's rogues gallery]].
* AppendageAssimilation: He wants to take Supergirl's biomatter and use it to rebuild his body. He succeeds, but is so distraught at his true identity that he gives her back her body so she can escape Brainiac.
* AppropriatedAppellation: When he explains that he isn't Superman, Kara calls him a Cyborg Superman and he keeps the name.
* [[spoiler:ArchnemesisDad: He's Kara's father, Zor-El]]
* TheDragon: He's working for Brainiac, [[DragonWithAnAgenda but has plans of his own]]. When he defies Brainiac, their fight allows Supergirl to escape.
* {{Foreshadowing}}: Kara notes that he seems familiar when she looks him in the eyes.
* IdentityAmnesia: He doesn't remember anything about himself. Not even his name. This is because [[spoiler:Brainiac erased his memories while rebuilding him to make him a loyal servant]]. He remembers everything after he becomes whole again, but is so distraught at his true identity that he has a change of heart and restores Supergirl's body; reverting him back into Cyborg Superman and removing his memories once more.
* [[MyGodWhatHaveIDone Sweet Rao, what have I done?]]: After he dissolves Supergirl and rebuilds his body with her biomatter, he regains his memories and realizes he's [[spoiler:Kara's father, Zor-El]]; shaking him to the core. To save Supergirl from Brainiac and keep her from knowing the truth, he restores her body and reverts back into Cyborg Superman so she can escape while he holds him off.
* NakedOnRevival: After his body is restored, the cybernetic parts fall off, leaving him naked. He remains naked for the duration before becoming a cyborg again.
* RedEyesTakeWarning: His left eye is a red cybernetic.
* RedRightHand: Cyborg Superman's right arm is lanky and skeletal; making him appear more inhuman than he already is.
* WeCanRebuildHim: He was on the verge of death when Brainiac found him and rebuilt him with cybernetics. He wasn't missing any body parts, but Brainiac wanted to make him the [[UltimateLifeForm ultimate Kryptonian]]. [[spoiler:Brainiac also altered Zor-El's DNA to make him look more like his "superior" brother, Jor-El]]. Cyborg Superman grows to hate his appearance and yearns to be fully biological again.

[[folder:The Dollmaker (Post-Crisis)]]
-->'''AKA:'''Anton Schott

The son of Post-Crisis Winslow Schott (alias long-time Superman foe, The Toyman), Anton Schott is a psychotic preteen who feels that his father loved other children more than he loved him, and despises all children because of it. He kidnaps children and sends dolls resembling them to Cat Grant, whom he ultimately tries to force to become his new mother.
* ChildProdigy: As both a toymaker and a supervillain.
* EnfanteTerrible: In his early teens at the latest, and utterly psychotic.
* EvilGenius: Clearly runs in the family.
* HappyFunball: Much like his father, Anton specialises in this.
* MommyIssues: Wants to force Cat Grant to be his new mother, actually.
* NonActionGuy: Anton himself is an out of shape child who can't fight to save his life.
* ParentalAbandonment: His mother took him away from his father because she believed he was a paedophile. Than she bailed on Anton as well, leaving him with serious abandonment issues.
* TheResenter: Towards any child with two functional parental figures.
* {{Robotmaster}}: Sends giant, doll shaped robots out to do his dirty work.

[[folder:Lesla-Lar (Pre-Crisis)]]
A villainous Pre-Crisis Kandorian scientist and Kara Zor-El lookalike who specialised in identity theft in both mundane and psychic versions. While she hasn't been seen since before the Crisis, she is historically significant as Supergirl's first true archenemy.

After a lengthy scheme to remove and take Supergirl's powers failed, partially due to Mr. Mxyptlk's interference, Lesla-Lar tried again by recruiting Phantom Zone criminals to aid her. Instead, they turned on her, disintegrating her with her own weapon. Her final appearance has her floating consciousness try to take over Supergirl's body once more, but this attempt failed and she was dispersed on the astral plane.
* CruelAndUnusualDeath: Unusually for the Silver Age, she was ''disintegrated on-panel'' in her second appearance. Her final appearance had her mental energy dispersed on the astral plane, killing her for good.
* EvilCounterpart: To Pre-Crisis Kara.
* GenreSavvy: Teamed up with Lex Luthor, planned to betray him before he could do the same to her.
* GrandTheftMe: Her main gimmick is identity theft.
* GreenEyedMonster: She was insanely jealous of Supergirl's fame, and thus decided to become her.
* HotScientist
* InexplicablyIdenticalIndividuals: To both Kara and Lena Thorul (Lex's sister). On different occasions she managed to kidnap and impersonate both with anyone being any the wiser.
* SanitySlippage: After being disintegrated, Lesla-Lar's consciousness lived on. This messed with her mind to the point where she thought Supergirl was her sister.
* UnknownRival: She exploited this trope, and was introduced as "Supergirl's Secret Enemy." It took almost five issues for Supergirl to find out who was behind all of her troubles.

[[folder:Lobo (New 52)]]
A Czarnian BountyHunter, Lobo came to Earth because he got word of an imposter using his name. He decides to go to the Block to interrogate Dr. Veritas on the imposter's whereabouts. Unfortunately for him, Supergirl is there and will not let him harm her friend.

For the other Lobo, see [[SelfDemonstrating/{{Lobo}} this page]].
* AbsurdlySharpBlade: His WeaponOfChoice are two large glowing knives that can cut through a man like butter.
* AdaptationalAttractiveness: Pre-New 52, he was a grizzled, burly NinetiesAntiHero. He's much more suave looking in the New 52, though his crass personality hasn't changed a bit.
* ADayInTheLimelight: He had his own Villains Month issue in September 2013, which set up his appearance in ''Supergirl''.
* {{Badass}}: He may look different, but he's still Lobo, and he can still brawl at Supergirl's level.
* BatmanGambit: He tries to use Supergirl's rage against her by taunting her into not holding back. As such, Dr. Veritas teleports them out of the Block to prevent their fight from damaging it. Once outside, Lobo calls his ship and flies to Supergirl's old apartment in New York, hoping to calm her down. He then tries to be friendly to her offering to mentor her so she can learn to control her rage. [[NiceJobFixingItVillain Big mistake]]. Supergirl has had it with people trying to manipulate her and gives him a NoHoldsBarredBeatdown.
* BountyHunter: Still works as a bounty hunter, and will do anything for money.
* CoversAlwaysLie: The cover for Lobo's Villains Month issue shows him looking like he did Pre-New 52. In the book, he looks like the above image. Lampshaded in the narration saying that you don't know this Lobo.
* EstablishingCharacterMoment: In his Villains Month issue, when he finds out the cargo is smuggling is a tribe innocent aliens, he acts nice to them. However, once they reveal they were abducted for their valuable bones, he forces back into the cage so he can get the large sum of money they're worth, not caring about their cries for mercy.
* ExactWords: When one of his employers reminds him that his contract forbids him from killing them, Lobo retorts that "it says nothing about maiming you."
* FakingTheDead: Thanks to his HealingFactor, he was able to recover getting punched by an angry Supergirl, but played dead so he could get in the Block.
* {{Foil}}: To Supergirl. Says writer Tony Bedard: "Lobo is there as a sort of dark reflection of her. They're both super-powerful loners left over from dead planets. Lobo has channeled his power and rage into becoming the most dangerous bounty-hunter/assassin in the galaxy. Supergirl's still trying to figure out what to do with her power and her lot in life. Tangling with Lobo will show her one path she might go down. It's really a cautionary tale for her, and she'll come away knowing that she could easily end up like him if she doesn't get her act together."
* HiredGuns
* IdenticalStranger: It appeared that Lobo's first New 52 debut was in ''Stormwatch'', where he looked just like he was pre-New 52. Then came Lobo's Villains Month issue and it reveals that there's another Lobo (the one on this page) who claims the Lobo in Stormwatch is an imposter that he is bent on finding and killing.
* {{Jerkass}}: Still a brutal thug at heart, with the personality to match.
* RedEyesTakeWarning: His eyes are blood red and lack pupils.

[[folder:Power Boy (Post-Crisis)]]
A superpowered boy who was Kara Zor-El's first boyfriend Post-Crisis, he eventually revealed himself as a clingy, abusive stalker from Apokolips.
* BitchInSheepsClothing
* DomesticAbuser

* MonsterOfTheAesop: A giant aesop about abusive boyfriends.
* NeverMyFault
* StalkerWithACrush
* WhyDidYouMakeMeHitYou

[[folder:Reactron (Pre-Crisis & Post-Crisis)]]
-->'''AKA:''' Benjamin Krullen (Pre-Crisis), Benjamin Martin Krull (Post-Crisis)

Once a sociopathic ex-soldier gifted with the ability to produce radiation, Post-Crisis Reactron was rebuilt as a cyborg with a Gold Kryptonite heart by ComicBook/LexLuthor and went onto play a major role during the ''New Krypton'' story arc, ultimately destroying New Krypton. Having faced Supergirl on numerous occasions pre-and-post-Crisis, and being the man responsible for the death of her father, Zor-El in the post-Crisis continuity, Reactron is one of the rare villains who can legitimately claim to be a member of Supergirl's RoguesGallery.
* {{Archenemy}}: Could make a legitimate claim on being Kara's archenemy, Post-Crisis and Pre-New 52. He had multiple clashes with Kara, solo and during the events of ''New Krypton'', had a deeply personal rivalry with her, possessed powers and weaponry that let him fight her on an even basis, and ultimately killed her [[spoiler:father, mother, and entire race]]. No other villain has ever come close to inflicting that sort of emotional damage on Kara; the fact that he was specifically created to be a Supergirl adversary Pre-Crisis doesn't hurt his claim on this status either.
* AxeCrazy: A violent psychopath who gets off on hurting and killing others.
* BlatantLies: His claim, Post-Crisis, that his costume was made of a captured region of space and granted him his powers. He admitted as much himself in ''New Krypton''.
* BlingOfWar: His golden armour and helmet.
* TheBrute: Like Metallo, Reactron has the persona down pat, and often plays this role in team ups.
* ChestBlaster: Reactron can fire a concentrated ray of Gold K radiation from his chest, depowering and severely injuring everything it hits.
* ColdBloodedTorture: Enjoys inflicting it and was on the recieving end of it courtesy of Alura.
* ColourCodedForYourConvenience: He wears gold to signify his Gold K heart, while Metallo wears green to represent his Green K one.
* {{Cyborg}}: After being rebuilt by ComicBook/LexLuthor on General Lane's orders. How much of him is man and how much is machine is open to interpretation.
* DirtyCoward: Subverted. He begs for his life when Supergirl and Alura capture him, and again when Gor is torturing him, but it is all revealed to be a ploy by he and Lane to hide the fact that they want him to be captured.
* DissonantSerenity: Smiles peacefully as he announces to Kara and Alura that he is a living nuclear bomb.
* DivergentCharacterEvolution: Inverted and then played straight. He began as an original Supergirl villain who was turned into a Metallo {{expy}} by Lane and Luthor at the start of ''New Krypton''. Afterwards, however, he went back in his own direction, becoming a mass-murdering psychopath on a scale that Metallo would have never dreamed of.
* EarthShatteringKaboom: When he explodes so does New Krypton.
* {{Expy}}: Reactron is an original villain, but during ''New Krypton'' he becomes an expy of Metallo, who Lane teams him up with.
* EyesOfGold: They glow bright golden yellow when he uses his powers.
* FamousLastWords: Manages to rattle of a little speech as he dies, explaining what is about to happen to Supergirl and Alura.
* FinalSolution: Becomes Lane and Luthor's solution to the Kryptonian problem, cheerfully annihilating almost the entire race in a single blast.
* {{Flight}}: Capable of propelling himself into the air and floating there.
* GoOutWithASmile: Is utterly serene as he blows up himself and New Krypton.
* HandBlast: Emits his nuclear radiation through his hands, fingertips, and palms alike.
* TheHeavy: During the four part ''Hunt for Reactron'' arc, and most of the issues leading up to it.
* HeManWomanHater: Expresses some very misogynistic sentiments.
* HeroKiller: After Luthor rebuilt him during ''New Krypton''. With his new cybernetic parts and Gold Kryptonite heart, Reactron can mow down Kryptonians in droves. He fights Flamebird, Nightwing, and Supergirl evenly, losing only when Flamebird--a Kryptonian god--unleashes her full power, and in the end, murders almost the entirety of the Kryptonian race.
* ImmuneToBullets: Bullets bounce off of Reactron. So too, do most other attacks, including Kryptonian punches. It may not be the NighInvulnerability of Superman himself, but there's no way around the fact that Benjamin Krull is a durable bastard.
* ISurrenderSuckers: How he got into New Krypton to kill Zor-El. He does it again in order to blow up the planet.
* ItsPersonal: After numerous clashes, and particularly after the events on New Krypton, it was very personal for he and Kara.
* {{Jerkass}}: When not being a monster, he tends to just act like a dick.
* JerkassHasAPoint: When he calls out Superwoman on the fact that JustFollowingOrders is no excuse for what she's done and that in the end, she's as bad as he is.
* KickThemWhileTheyAreDown: His whole motif after he gains the Gold K heart. He powers down Kryptonians, then irradiates them.
* KilledOffForReal: In the Post-Crisis, Pre-Flashpoint world he never recovered from his death in ''New Krypton''.
* LackOfEmpathy: Reactron cares only about himself and how famous his killing is going to make him.
* MajorlyAwesome: Fomrerly Major Benjamin Martin Krull, US Army, and still referred to as such by Lane and Luthor.
* ManOfKryptonite: His Gold K heart deactivates a Kryptonian's powers for fifteen seconds, more than long enough for Reactron to finish the job with his radiation powers or his bare hands.
* NotSoHarmlessVillain: In his first Post-Crisis attack on her, Supergirl notes that for a guy with near limitless power, Reactron isn't thinking very big, or using his powers very intelligently. Cue the events of ''New Krypton''.
* NuclearNasty: Emits nuclear radiation, and with help from Luthor, can transform into a bomb.
* NukeEm: Turns into a massive nuclear bomb.
* PsychoForHire: When not operating as a member of the US Army, Krull falls into this territory.
* {{Retcon}}: Reactron was a Pre-Crisis Supergirl villain. Post-Crisis his early battles with the original Kara Zor-El were retconned into having been against Power Girl.
* {{Sadist}}: Reactron really, really enjoys hurting people, to a level that's normally reserved for the likes of TheJoker.
* SkullForAHead: A skull mask to be more precise.
* TheSociopath
* SociopathicSoldier: Enjoys murder, torture, and the occasional threat of rape. Pre-Crisis, he was one of these even before becoming Reactron, having massacred an entire village as a sergeant in Vietnam.
* SuicideAttack: On New Krypton. Reactron let himself be captured and tortured, with the intention of letting Luthor convert him into a nuke so that he could blow the entire planet apart.
* SuperSpeed: It's rarely mentioned, but much like Metallo, Reactron is able to keep up with Kryptonians, meaning that he has to possess at least a degree of super speed.
* SuperStrength: Between being supercharged by radiation and rebuilt with cybernetics, Reactron is strong enough to injure the likes of Supergirl, Flamebird, and Nightwing with his blows.
* ThoseTwoBadGuys: He and Metallo enter ''New Krypton'' this way. They don't end it that way, with Reactron going on to be far more significant to the story.
* UnderestimatingBadassery: Everybody does this to him during ''New Krypton'', with very bad results.
* UngratefulBastard: Kara saves him from being tortured by Alura. He pays her back by detonating himself, killing her mother and her entire race in an attempt at getting to her. "Glad I got the whole family set."
* YouKilledMyFather: During the events of ''New Krypton'' Reactron kills Supergirl's father, Zor-El, in front of her. He later gets her mother, and the rest of her race.

[[folder:Reign (New 52)]]

The leader of the Worldkillers, a QuirkyMinibossSquad of Kryptonian-created {{Super Soldier}}s, and one of the first major enemies Supergirl faced in the ''New 52''. [[spoiler: It is ''heavily'' hinted that Kara's father Zor-el is her creator, as he is established as having worked on the Worldkillers and in Issue Zero what is either Reign or a being very much like her can be seen in stasis in a pod in his lab]].

* {{BFS}}: Wields one initially- [[SubvertedTrope until Kara breaks it with her bare hands]]. Reign is not amused.
* BloodKnight: Reign ''loves'' to fight, and she's [[SuperSoldier very good at it]].
* DarkActionGirl
* DistaffCounterpart: She's basically a female, rather more articulate Doomsday with a bit of Zod mixed in.
* EvilCounterpart: Clearly positions herself as one in much of her dialogue to Kara. [[spoiler: Especially since, if the hints as to her backstory are true, she's something of a daughter of Zor-el herself]].
* FlyingBrick: Her powers are explicitly identified as flight, strength, and invulnerability.
* GalacticConqueror: What she was created to be. It's unclear if she and her companions have ''actually' conquered anything yet, but they make a good try for Earth.
* HumanoidAliens: She's roughly human/Kryptonian in appearance, except for her unnaturally pale skin, solid black eyes, and PointedEars. Her face is also shaped subtly different from a human's, with a slightly reptillian cast remniscent of [[Franchise/HarryPotter Lord Voldemort]].
* JustBetweenYouAndMe: She explains her backstory to Kara while they're fighting in New York City. Slightly deconstructed in that Kara is too busy defending herself to pay much attention.
* [[ImplacableMan Implacable Woman]]: Thanks to her FlyingBrick powers, she can take massive hits and just keep coming.
* NotSoDifferent: Feels this way about herself and Supergirl.
* ObviouslyEvil: She's pretty sinister looking. For example, she has:
** BlackEyesOfEvil: Jet-black eyes
** EvilAlbino: Chalky white skin
** EvilRedhead: Fiery red hair.
** SensibleHeroesSkimpyVillains / {{Stripperiffic}}: A rather skimpy outfit that's mostly composed of black leather.
* PetTheDog: Evil and brutal she may be, but she values the lives of her fellow Worldkillers, and retreats rather than allow Kara to kill even one of them.
* SuperSoldier: She and her fellow Worldkillers were intended as the ultimate weapon by the Kryptonian scientists who created them.
* VillainExitStageLeft: Retreats from Earth at the end of the arc that introduced her, but with the promise that she'll be back- and that there's one more Worldkiller out there that Supergirl doesn't know about...
* WeCanRuleTogether: Makes Supergirl this offer at their first meeting. When Kara refuses, Reign decides she wasn't worthy anyway.

[[folder:Satan Girl]]
-->'''AKA''': Red Kryptonite double of Kara Zor-El (Pre-Crisis), Dolores Pratchett (Satan Girl I), S'tanicule Gyrstress (Satan Girl II)

One of the most perplexing and intriguing enemies in Supergirl's RoguesGallery, in that name has been shared by three vastly different individuals across the Pre-Crisis and Post-Crisis DCU. The original Satan Girl of the Pre-Crisis DC Universe was an evil doppelganger of Supergirl created by Red Kryptonite, and she attempted to kill Kara and the female members of the ComicBook/{{Legion of Super-Heroes}} to attain dominance. Post-Crisis, Satan Girl was Dolores Pratchett, an 18th Century Satanist who fought against Matrix and Linda Danvers, and the name would be given to S'tanicule Gyrstress, an alien demon who fought the Post-Crisis Kara. There were plans for a fourth iteration to appear in the sequel to ''Cosmic Adventures in the 8th Grade''.

* AntiVillain: The duplicate Kara and Dolores straddle the lines between Type II and Type III.
* ArchEnemy: The Dolores Satan Girl was one to Ember, the Earth Angel of Fire who preceded Matrix and Linda.
* AtLeastIAdmitIt: Dolores' whole shtick with Ember is that she's disgusted at the idea of Ember becoming an Earth Angel even though she was no better than Dolores, and that Ember tries to act HolierThanThou. Although Dolores is also a child murderer, a racist, and considers Ember a creature because she was her slave. [[spoiler: There's also her bitterness at the fact that Ember was saved because Dolores' daughter Rachel sacrificed herself to save her and the two became one. Dolores is angry because Rachel became a part of their feud, and when Ember was damned, so was Rachel.]]
* BackFromTheDead: Dolores' first actual appearance was when she got revived by the Chaos Stream.
* EvenEvilHasLovedOnes: Dolores. [[spoiler: She became Satan Girl because her daughter Rachel died trying to save Ember, and the two were reborn as the new Earth Angel of Fire. Dolores' plans were all meant to try and separate her daughter from Ember so she could have her back, but it just led to Rachel's damnation when Ember killed Dolores. Thankfully, the intervention of Supergirl not only stopped Dolores' rampage, but allowed Ember and Rachel to enter Heaven.]]
* EvilCounterpart: Pre-Crisis Satan Girl to Supergirl.
* EvilRedhead: Dolores and S'tanicule.
* HatePlague: The crimson plague S'tanicule unleashes to make the world love her also turns people into bloodthirsty monsters.
* HornedHumanoid: With HornyDevil, S'tanicule is the most satanic looking of all the Satan Girls.
* MadGod: S'tanicule Gyrstress is the Brocian goddess of love and death.
** PowerOfLove: An evil variant.
* MakeWrongWhatOnceWentRight: A very weird subversion. Dolores' magic ends up switching Supergirl and Ember, and she tries to convince Ember that she can live if she lets Supergirl die in her place. [[spoiler: This is all to try and circumvent her daughter Rachel's eventual death, rebirth, and damnation, so this becomes a slight case of SetRightWhatOnceWentWrong.]]
* MamaBear: Dolores is a very evil version.
* MoralityPet: Dolores' daughter Rachel.
* MythologyGag: When Dolores Pratchett originally became Satan Girl before her first death, she wore the Pre-Crisis Satan Girl's costume.
* PyrrhicVictory: In a way, Dolores got what she wanted. [[spoiler: Even though she dies again and doesn't necessarily get Rachel back, her actions helped pave the way for Rachel's ascension into Heaven, so she's no longer suffering.]]
* WhatMeasureIsANonHuman: All the Pre-Crisis Satan Girl wanted to do was live, albeit at the expense of the lives of Supergirl and the female Legionnaires.
* WomanScorned: Dolores Pratchett taught her slave Ember all there was to know about the Dark Arts, but when Ember slept with her husband, Dolores denounced her publicaly as a witch.
* WouldHarmAChild: Dolores Pratchett attained ungodly power after sacrificing children.
* YeOldeButcheredEnglish: Dolores originally spoke like this, but when her enemy Ember switched places with Supergirl, she opted to drop the formal "thees" and such.

A twenty-eight year old trillionaire who lives on a space station and rarely ever sets foot on Earth. When Supergirl landed on earth in the ''New 52'' he captured her and held her on board his space station hoping to contract some of her Kryptonian blood. [[spoiler:An explosion during Supergirl's escape left most of his body destroyed yet his assistant Miss Thorn was able to graft him onto the body of "The Brain", an organism of basic nerves and a brain, to keep him alive]].

* AndIMustScream: Supergirl defeats him in their second encounter by having Sanctuary encase him in crystal. [[spoiler:He is possibly dead after Supergirl and Power Girl destroy Sanctuary after it turned evil]].
* BodyHorror[=/=]EmergencyTransformation: [[spoiler:He had to be merged with an alien blob after Supergirl's escape left him in pieces. What's left of his human body is his upper torso, most of his head, and his right eye]].
* RubberMan: His transformation gave him stretching powers, shapeshifting, and invulnerability.
* SharpDressedMan: He used to be one.
** {{Loincloth}}: What he wears now. It shows off his new body quite well.
* WhatHappenedToTheMouse: [[spoiler:He's left frozen in crystal somewhere in the Sanctuary. When Santuary is destroyed, there is no mention of him, leaving readers to assume that he died along with Santuary. Lampshaded in issue #23, where Supergirl fights robot clones of people from her memories and the Tycho robot says that they had to go deep into her subconscious to find memories of him; implying that he must pretty forgettable and bringing up him being left for dead]].
* WhiteHairBlackHeart: Before his transformation.
** BaldOfEvil: Afterwards.

[[folder:Superior Girl (Cosmic Adventure)]]
-->'''AKA:''' Belinda Zee

A dark-haired Kryptonite duplicate of Supergirl who called herself Belinda as she is "Linda Version B." Belinda is everything Linda Lee isn't. That is, she's smug, self-absorbed, has no desire to be a superhero, and loves to make Linda miserable because if Linda wants to be happy, Belinda wants her to be miserable. Not necessarily a villain, she falls under ChaoticNeutral, and her emotions are on a constant hair trigger. We later find out she has horribly low self esteem and actually wants to be nice, but feels totally backwards.

* AffablyEvil
** FauxAffablyEvil
* AlphaBitch
* AnimalsHateHim: She gets mauled by Streaky.
* AxCrazy: What she degenerates into.
* BodyHorror: [[spoiler: Promotional art for the non-produced ''Cosmic Adventures in the 9th Grade'' showed Belinda's face had started to crack after she was turned into a crystal statue.]]
* ChaoticNeutral: WordOfGod described her as such.
* [[DarkIsEvil Dark is Chaotic Neutral]]: She starts out with a Supergirl costume containing an inverted color scheme and a backwards S, but when she becomes Superior Girl she's wearing a a Supergirl costume with purple and black.

* EvilCounterpart
* FalseFriend: She once tried pretending she was Linda's best friend to drive a wedge between her and Lena.
* ForTheEvulz: Why she makes Linda squirm so much.
* ItsAllAboutMe
* {{Expy}}: Of Bizarro.
* ManipulativeBitch
* PetTheDog: In one moment of genuine kindness she makes Lena Thorul forget who Supergirl really is. Belinda had nothing to gain from this and actually helped Linda with no provocation.
* TheReasonYouSuckSpeech: She delivers one to Linda when they first meet. Linda's at first excited at the idea of having another Kryptonian for a friend, but Belinda just says she's a frumpy klutz who's desire to be a superhero is totally not cool. Linda then realizes she's a supervillain.
* {{Sadist}}
* SmugSnake
* StepfordSmiler: Despite thinking she's completely awesome, she's really miserable and doesn't know why.
* TakenForGranite: And [[AndIMustScream sentient]].
* TeachersPet
* TragicVillain
* UnwittingPawn: Of [[spoiler: Mr. Mxyzptlk.]]
* VillainousBreakdown: When Linda's mom (who is also technically her mom) doesn't recognize her, Belinda breaks down into tears and starts screaming she's "Number One."
* WomanScorned: An odd variant. When she meets Supragirl, Linda's counterpart from an AlternateTimeline, Belinda flips and think's she being replaced, screaming she was the first Supergirl doppelganger, so she's the original.
-->'''Supergirl''': If you're number one, and I was here first, what does that make me?

Siobhan is a good natured Irish punk girl living in New York and the first human being the New 52 Kara meets who doesn't try to capture and/or kill her. While the two quickly become friends (aided by Siobhan's ability to speak Kryptonian) Siobhan's past catches up with her; her father is the evil magical being Black Banshee and she herself is having difficulty keeping her own powers in check as the even more frightening Silver Banshee.

For pre-ComicBook/{{New 52}} Silver Banshee, see [[Characters/SupermanVillains Superman's rogues gallery]].
* EvilMeScaresMe: Siobhan fears that the Silver Banshee will take over her body when it manifests.
* HeroicWillpower: When fighting [[spoiler:Red Lantern Supergirl]], she's able to mostly stay in control as the Silver Banshee.
* IrishNames: 'Siobhan' (pronounced 'Shiv-awn')
* TheLadette
* MakeMeWannaShout: As the Silver Banshee, she has the appropriate sonic screams.
* {{Oireland}}: She has the accent at the very least.
* {{Omniglot}}: An actual super power; due to her quasi-magical nature Siobhan is able to speak ''any'' language she hears, even a non-human one like Kryptonian (if the dialogue is any indication she always retains her Irish accent though.)
* SuperpoweredEvilSide: Her Silver Banshee form.

[[folder:Zor-El & Alura (Post-Crisis)]]
Kara's parents in the Post-Crisis universe, Zor-El and Alura where members of the Science Guild stationed in an offworld colony. Captured by Brainiac, they were added to his bottled city of Kandor, and eventually freed by Superman. While Zor-El is a certified NiceGuy, Alura is a KnightTemplar kept in check only by her husband.
* ActionMom: Alura
* BlondesAreEvil: Alura
* ColdBloodedTorture: Alura does this to Reactron.
* DarkActionGirl: Alura
* EvenEvilHasLovedOnes: Alura definitely cares about both Zor-El and Kara.
* EvilMatriarch: Alura, who tries to control every aspect of Kara's life, and is a KnightTemplar at best.
* HappilyMarried
* HeroicSacrifice: Alura dies saving Kara from Reactron.
* HorribleJudgeOfCharacter: Alura believes that all humans are scum, that Superman can't be trusted, and that General Zod is a great hero. She couldn't be more wrong about any of the above.
* KickTheSonOfABitch: Alura's torture of Reactron is wrong and is portrayed that way, but given that we're talking about the single worst member of Supergirl's rogues gallery here, you aren't liable to have much sympathy for him.
* KilledOffForReal: Zor-El dies in battle with Reactron. Alura is killed when Reactron blows himself up, wiping out all of New Krypton.
* KnightTemplar: Alura. Zor-El knows it too, and tries to act as a check on her.
* MamaBear & PapaWolf: Don't hurt Kara in front of either of them.
* NiceGuy: Zor-El
