    Supergirl (Pre-Crisis)
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 Batgirl I (Barbara), became a member of the 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 The Multiverse, 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.

During Convergence, Kara was one of many individuals pulled from their respective timelines and universes and trapped in domed cities by Brainiac. Pulled before her death, Kara learned about her impending sacrifice being needed to stabilize the timeline, only thanks to the combined efforts of her, the pre-Crisis Barry Allen, Hal Jordan as Parallax, and the pre-Flaspoint Superman, the original Multiverse was saved and Kara is no longer dead.

    Supergirl I (Post-Crisis) 
AKA: Matrix

A purple shape-shifting creature from a Pocket Dimension, she was created by that universe's Lex Luthor and patterned after the 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 Post-Crisis Supergirl. She later accidentally fused with Linda Danvers below, and made her the next Supergirl.
  • Artificial Human
  • Brainwashed and Crazy: She was one of a number of heroes implanted with Trigon Seeds during one of Raven's Face–Heel Turn stints.
  • Flying Brick: Even more so than Superman.
  • Naïve Newcomer: So naive she shacked up with LEX LUTHOR!
  • No-Holds-Barred Beatdown: She does this in her Convergence miniseries when she finally has enough of Lex's bullshit.
  • Put on a Bus: Same as Linda below.
  • Invisibility: One of her lesser-used powers.
  • Secret Test of Character: The opening arc of Peter David's run pushed Mae past her limit, placing her in situations that tested her moral resolve and forcing her to question her own goodness when told she was merged with a thoroughly corrupted person (Linda). It turned out everything she'd gone through was an attempt by Buzz and his demonic overseers to turn Supergirl over to the dark side, but at the last second she relented.
  • Shape Shifter: She even thought she was Superman for a brief time.
  • Telekinesis: The source of most of her powers.
  • Tin Man: 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 everyone who knew it really was Matrix stated she had more of a soul than Linda did up to that point, including Linda.
  • Woman Scorned: When she finds out Lex is evil.

    Supergirl II (Post-Crisis) 
AKA: Linda Lee Danvers

  • The Atoner: For her sins as a cultist and several other mistakes.
  • Bare Your Midriff: Her second costume. Lampshaded in the comic when a cop called it her "Britney Spares" outfit.
  • Corrupt the Cutie: What Buzz did to her, though she admits everything she did was of her own free will.
  • Deadpan Snarker
  • Despair Event Horizon: She crossed this twice. The first time was after witnessing her pastor beat his wife to death when she was a young girl. The second time was after she was forced to send the pre-Crisis Kara Zor-El back to her universe and her eventual death, as well as losing her daughter even though she'd been told Ariella would be spared from erasure.
  • Fallen Angel
  • Happily Married: Spent five years married to the Superman of Earth-One after switching places with Kara.
  • Heel–Face Revolving Door
  • Mama Bear: Was willing to let the universe fall apart if her daughter wasn't spared from being retconned.
  • Moral Event Horizon: In-universe she crossed this while she was allied with Buzz, and it's the whole reason she became an Earth-Angel when merged with Matrix.
  • Mythology Gag: 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.
  • Playing with Fire
  • Put on a Bus: After her series ended, Linda pretty much dropped out of The DCU. She hasn't been consigned to Canon Discontinuity, but she's barely ever mentioned anymore, either.
  • Secret Identity: As Linda, though by the end of the series, pretty much everyone knows.
  • Shout-Out / Canon Immigrant: Her second costume is based on DCAU Supergirl.

    Supergirl III (Post-Crisis) 
AKA: Cir-El

    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 Batman and Wonder Woman, 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).
  • Abusive Parents: 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 Knight Templar 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 Nice Guy.
  • Alliterative Name: Linda Lang
  • Alternate Self: She and Power Girl are this to one another, which leaves Kara very weirded out about the possibility of meeting her.
  • Anti-Hero: Before Character Development 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.
  • Badass Cape
  • Bash Brothers: With Wonder Girl. She and Superman and she and Dick Grayson are a platonic, two-gender variant.
  • Bare Your Midriff
  • Battle Couple: With Brainiac 5.
  • Belligerent Sexual Tension: With Brainiac 5, whose attitude and frosty demeanour rub her the wrong way.
  • Brains and Brawn: With Brainiac 5. She's the brawn, he's the brains.
  • Calling the Old Man Out: Does this to her mother near the end of "New Krypton" after she finds her torturing Reactron.
  • The Cape: 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 issues, built strong friendships with other heroes, and was well on her way to being the same sort of paragon as her cousin.
  • Clark Kenting: Used glasses and a different haircut to become Linda Lang.
  • Curb-Stomp Battle: On the receiving end of an absolutely brutal one from Lex Luthor early in her career, which forced her to realize that she did, in fact, need to start thinking her actions through more.
  • Daddy Issues/Mommy Issues: Originally she was shown to have serious issues with her dad. These were eventually retconned out and replaced with a strained relationship with her Evil Matriarch Knight Templar mother.
  • Daddy's Girl: Once all the retcons were hashed out.
  • Dark Action Girl: Dark!Kara who was originally a far more capable fighter than the actual Kara.
  • Darker and Edgier: She got over it.
  • Defeat Means Friendship: With Bizarrogirl
  • Distaff Counterpart: To the Post-Crisis Superman.
  • Emo Teen: 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.
  • Enemy Within: Dark!Kara who embodies all of Supergirl's repressed anger over the loss of her people.
  • Enemy Without: 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 before being stopped.
  • Evil Costume Switch: The black costume sported by Dark!Kara.
  • Fish out of Water: 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.
  • Groin Attack: What she did to a stalker; fortunately, he was from Apokolips so it ONLY hurt a whole lot.
  • Happily Adopted: By Lana Lang, whose niece she is pretending to be.
  • Has a Type: Her crushes on Dick Grayson and Brainiac 5 are indicative that Kara has a thing for intellectual, responsible-leader types.
  • Heel–Face Turn: Dark!Kara starts out as a monster who was prepared to murder her cousin in the name of Darkseid. By the time of her final appearance she's little more than an emotionally immature teenager who despite her problems still wants to help all of Kara's friends and nearly gets herself killed protecting Dick Grayson from Doomsday.
  • Hot-Blooded: At least when compared to her cousin. Kara tends to charge into situations without thinking, which nearly got her killed against Luthor.
  • Interspecies Romance: Any relationship she has with a non-Kryptonian is this by definition. Most notably with Brainiac 5.
  • It's Personal: 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.
  • Like Brother and Sister: She and Dick Grayson (Robin I/Nightwing/Batman III) have this vibe, with him considering her a little sister.
  • Magic Skirt: Always covered up no matter what.
  • Mentor Ship: Had a one-sided crush on the older Nightwing when she first met him. Their relationship later becomes Like Brother and Sister.
  • Minidress of Power
  • Ms. Fanservice: Her costume is basically a cheerleader outfit.
  • No Social Skills: Angry, emotionally damaged, and unfamiliar with Earth's customs, Kara gets herself in a lot of trouble during her first few years on Earth.
  • Odd Couple: Energetic former Emo Teen Kara and frosty, intellectual Brainiac 5.
  • Older Than They Look: 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.
  • Plucky Girl: After Character Development.
  • Precocious Crush: On Dick Grayson. She eventually gets over—though dark!Supergirl does not.
  • Replacement Goldfish: After Superboy's death, Cassie develops a close friendship with Kara. Later on, she decides to cut off ties with Kara specifically because of this trope. 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. Doctor Fate later suggests that the hallucinations, as well as dark!Supergirl are manifestations of Kara's survivors guilt which she has no idea what to do with.
  • Romantic Two-Girl Friendship: With Wonder Girl in the Teen Titans. They nearly kissed in Supergirl: Identity.
  • Save the Villain: Actually tries to save Reactron from being tortured by her mother.
  • Savvy Guy, Energetic Girl: The energetic girl to Brainiac 5's savvy guy.
  • Secret Identity: Linda Lang.
  • Split Personality Takeover: Happens several times be it under Darkseid's influence or simple stress. In a variation on the usual, Dark!Kara becomes more controllable and less evil each time it happens.
  • 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.
  • Superpower Lottery: Including...
  • Superpowered Evil Side: Dark!Kara, who is released under the influence of Darkseid, Black K, or similar events and has none of our Kara's restraint. 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.
  • Survivor's Guilt: 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.
  • The Tease: She liked taunting Captain Boomerang Jr. about his obvious crush on her. She eased up on it when she realized it was a real Jerk Ass thing to do.
  • There Are No Therapists: 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.
  • Took a Level in Badass: Over the course of her series.
  • Underestimating Badassery: People tend to this to Kara on account of her age and lack of experience. Kara herself does this to Lex Luthor early in her career, and to Reactron in New Krypton, with disastrous results both times.
  • Unskilled, but Strong: 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 Lex Luthor.
  • Villainesses Want Heroes: In a strange variation Dark!Kara has a pretty serious crush on Dick Grayson.

    Supergirl 1,000, 000
AKA: Ariella Kent

The daughter of Linda Danvers and an alternate Silver Age Superman. After her parents were erased by the Crisis on Infinite Earths and The Spectre's interference, Ariella was left to wander space and time on her own.

    Supergirl (Cosmic Adventures)
AKA: Linda Lee/Kara Zor-El

An alternate version of Kara from the all-ages comic, Supergirl: Cosmic Adventures in the 8th Grade.

    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.
  • Adaptational Angst Upgrade: You kinda expect her to be more easy-going, especially if you're most familiar with the Kara from Superman: The Animated Series as many casual fans are. So the fact that she can 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.
  • Aliens Speaking English: Averted and later played straight: Kara could only speak Kryptonian at first and was taking English lessons from Siobhan. When she met fellow kryptonian H'el in Issue #14, he gave her the ability to understand and speak English perfectly.
  • Alternate Self: Supergirl and Power Girl 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, 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.
  • Boyish Short Hair: As a small child.
  • Character Development: 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.
  • Determinator: Kara never quits. Never. Not even when she's poisoned with Kryptonite, her body is getting stolen by an alien abomination, and her heart has stopped. Even so, she'll keep fighting. She explains that her mother taught her to never give up.
    Supergirl: But then I thought of mother. I remembered all I had to live up to. A daughter of the House of El never quits. I wasn't about to be the first.
  • Fantastic Racism: 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 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 Hot-Blooded. Here, her anger is an actual plot point 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 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.
  • The Big Gal: 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.
  • Flying Brick
  • Hair-Trigger Temper: After showing up on Earth Kara was very irritable and snappy due to months of being manipulated, abused and betrayed in addition to be an orphan of a dead world. Her temper got worse, to the point she eventually became a rage-powered Red Lantern. During her RL stint, she barely could control her anger, and she often blew up with no reason or provocation and regretted her outbursts afterwards. Paradoxically, that situation taught her how to keep her temper under control.
  • Hero with Bad Publicity: 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.
  • How Do I Shot Web?: Supergirl had a hard time adjusting to her new-found powers when she landed on Earth.
  • Leotard of Power: Unlike previous incarnations, Supergirl's outfit in the New 52 lacks a skirt.
  • Made of Indestructium: Her outfit and cape.
  • My Blood Runs Hot: From Supergirl 28 through Supergirl 33, with the same Red Lanterns issues, Kara is the recipient of a Red Lantern Ring, while still keeping her Kryptonian abilities.
  • Most Common Superpower: Averted. She has a rather modest bust to match her slim teenage physique.
  • Naked on Revival: 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.
  • Nice Girl: 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.
  • No Social Skills: 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 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.
  • Older Than They Look: 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 Kal-El looks older than her.
  • Perpetual Frowner: 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.
  • Rage Breaking Point: 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 thrash him. Her rage is enough to attract a Red Lantern ring.
  • Smarter Than You Look: Her hot temper, teenage naivete and lack of fighting finesse leads a lot of enemies to consider her simply Dumb Muscle. In fact she does have brains - as witnessed by her outwitting Tycho and Sanctuary.
  • Superpower Lottery: Since she's a Kryptonian like Superman, she has the same powers as him.
  • Teeth-Clenched Teamwork: every time she worked with Superboy, at least at first, due to Kryptonian Fantastic Racism 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 go through her.
  • Tomato in the Mirror: Reign suggests to her that she is the fifth, missing Worldkiller. Kara denies it but deep down worries Reign might be right.
  • Trauma Conga Line: she woke up with missing memories, on an alien world, all alone and was promptly attacked by men in Powered Armour. 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 then the 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 turns out to be 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 Face–Heel Turn. Then, in defeating H'el, she's poisoned with Kryptonite. Again. And then there's the revelation that her father was experimenting on her. No wonder the poor girl has problems.
  • Underwater Base: 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.
    • A.I. Is a Crapshoot: 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. The two Karas must destroy Sanctuary to save Supergirl. However, the A.I. survives in a robot body; hellbent on destroying Supergirl.
  • Unskilled, but Strong: 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.
  • Working Through the Cold: The events of H'el on Earth 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.
  • When She Smiles: It's rare, but it is absolutely adorable. Becomes more common after the Red Daughter Of Krypton arc allows her to let go of most of her rage.
  • You Can't Go Home Again: She really wants to go back home to Krypton, but can't since Krypton was destroyed. This motivates her temporary Face–Heel Turn in H'el on Earth. Superman's perceived indifference towards Krypton and its fate is one of the causes of friction between them.


    Bizarrogirl (Pre-Crisis & Post-Crisis) 
There were two different Bizarro versions of Supergirl in Pre-Crisis continuity. The first was pretty much just a Gender Flip 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 Brainless Beauty.

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.

    Buzz (Post-Crisis) 

  • Arch-Enemy: To Matrix and Linda Danvers.
  • Been There, Shaped History: Was retroactively included in Raven's backstory by making him a part of the cult that set up Angela Roth to be raped by Trigon.
  • The Corrupter: He put young Linda through the wringer.
  • Evil Brit: Slightly came across as a sleazy, evil John Constantine.
  • Faux Affably Evil: He actually managed to charm Sylvia Danvers so well she set up a blind date for him and Linda at one point. But it was all a ruse to set up a scenario wherein the Danvers would die, pushing Supergirl past the Despair Event Horizon. Thankfully this gets undone.

    Cyborg Superman (New 52) 
AKA: Zor-El

After H'el on Earth and 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-New 52 Cyborg Superman, see Superman's rogues gallery.
  • Appendage Assimilation: 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.
  • Appropriated Appellation: When he explains that he isn't Superman, Kara calls him a Cyborg Superman and he keeps the name.
  • Archnemesis Dad: He's Kara's father, Zor-El
  • The Dragon: He's working for Brainiac, 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.
  • Identity Amnesia: He doesn't remember anything about himself. Not even his name. This is because 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.
  • 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 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.
  • Naked on Revival: After his body is restored, the cybernetic parts fall off, leaving him naked. He remains naked for the duration before becoming a cyborg again.
  • Red Eyes, Take Warning: His left eye is a red cybernetic.
  • Red Right Hand: Cyborg Superman's right arm is lanky and skeletal; making him appear more inhuman than he already is.
  • We Can Rebuild Him: 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 ultimate Kryptonian. 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.

    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.
  • Child Prodigy: As both a toymaker and a supervillain.
  • Enfante Terrible: In his early teens at the latest, and utterly psychotic.
  • Evil Genius: Clearly runs in the family.
  • Happy Funball: Much like his father, Anton specialises in this.
  • Mommy Issues: Wants to force Cat Grant to be his new mother, actually.
  • Non-Action Guy: Anton himself is an out of shape child who can't fight to save his life.
  • Parental Abandonment: 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.
  • The Resenter: Towards any child with two functional parental figures.
  • Robotmaster: Sends giant, doll shaped robots out to do his dirty work.

    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.
  • Archenemy: Of Pre-Crisis Kara.
  • Cruel and Unusual Death: 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.
  • Evil Counterpart: To Pre-Crisis Kara.
  • Genre Savvy: Teamed up with Lex Luthor, planned to betray him before he could do the same to her.
  • Grand Theft Me: Her main gimmick is identity theft.
  • Green-Eyed Monster: She was insanely jealous of Supergirl's fame, and thus decided to become her.
  • Hot Scientist
  • Inexplicably Identical Individuals: 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.
  • Sanity Slippage: After being disintegrated, Lesla-Lar's consciousness lived on. This messed with her mind to the point where she thought Supergirl was her sister.
  • Unknown Rival: 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.

    Lobo (New 52)
A Czarnian Bounty Hunter, 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.
  • Absurdly Sharp Blade: His Weapon of Choice are two large glowing knives that can cut through a man like butter.
  • Adaptational Attractiveness: Pre-New 52, he was a grizzled, burly Nineties Anti-Hero. He's much more suave looking in the New 52, though his crass personality hasn't changed a bit.
  • A Day in the Limelight: He had his own Villains Month issue in September 2013, which set up his appearance in Supergirl.
  • Batman Gambit: 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. Big mistake. Supergirl has had it with people trying to manipulate her and gives him a No-Holds-Barred Beatdown.
  • Bounty Hunter: Still works as a bounty hunter, and will do anything for money.
  • Covers Always Lie: 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.
  • Establishing Character Moment: 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.
  • Exact Words: When one of his employers reminds him that his contract forbids him from killing them, Lobo retorts that "it says nothing about maiming you."
  • Faking the Dead: Thanks to his Healing Factor, 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."
  • Hired Guns
  • Identical Stranger: 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.
  • Red Eyes, Take Warning: His eyes are blood red and lack pupils.

    Matrix (Post-Crisis) 
After Matrix and Linda Danvers merged, there were remnants of Matrix's protoplasmic form left over. The remnants took on a life of their own, becoming a new individual that tried to overwhelm Supergirl and went on a rampage in Leeville.

  • Evil Counterpart: To Mae Kent. She even had some of the powers Mae lost after combining with Linda, such as invisibility and telekinesis.
  • Expy: Her inhuman appearance and the backwards "S" she wore implicitly made her the first Bizarro-like character to fight the Post-Crisis Supergirl.
  • Small Role, Big Impact: While not as substantial as Supergirl's other enemies Post-Crisis, the destruction she caused in Leeville caught Superman's attention which finally led to him learning about Mae and Linda's dual existence.

    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.

    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 Lex Luthor 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, her mother Alura, and most of her friends, in the post-Crisis continuity, Reactron is one of the rare villains who can legitimately claim to be a member of Supergirl's Rogues Gallery.
  • 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 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.
  • Arc Villain: From the beginning of "New Krypton" until his death in "War of the Supermen" Reactron dominated the Post-Crisis Supergirl book as no one had before.
  • Attack Its Weak Point: Detective Henderson managed to take Reactron out of action with a frankly spectacular shot through the eye slots of his mask, and into the eye beneath.
  • Axe Crazy: A violent psychopath who gets off on hurting and killing others.
  • Blatant Lies: 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.
  • Bling of War: His golden armour and helmet.
  • The Brute: Like Metallo, Reactron has the persona down pat, and often plays this role in team ups.
  • Chest Blaster: Reactron can fire a concentrated ray of Gold K radiation from his chest, depowering and severely injuring everything it hits.
  • Cold-Blooded Torture: Enjoys inflicting it and was on the recieving end of it courtesy of Alura and Gor.
  • Colour-Coded for Your Convenience: He wears gold to signify his Gold K heart, while Metallo wears green to represent his Green K one.
  • Cyborg: After being rebuilt by Lex Luthor on General Lane's orders. How much of him is man and how much is machine is open to interpretation.
  • Dirty Coward: 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.
  • Dissonant Serenity: Smiles peacefully as he announces to Kara and Alura that he is a living nuclear bomb.
  • Divergent Character Evolution: 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.
  • Earth-Shattering Kaboom: 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.
  • Eyes of Gold: They glow bright golden yellow when he uses his powers.
  • Famous Last Words: Manages to rattle of a little speech as he dies, explaining what is about to happen to Supergirl and Alura.
  • Final Solution: 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.
  • Go Out with a Smile: Is utterly serene as he blows up himself and New Krypton.
  • Hand Blast: Emits his nuclear radiation through his hands, fingertips, and palms alike.
  • The Heavy: During the four part Hunt for Reactron arc, and most of the issues leading up to it.
  • He-Man Woman Hater: Expresses some very misogynistic sentiments.
  • Hero Killer: 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.
  • I Surrender, Suckers: How he got into New Krypton to kill Zor-El. He does it again in order to blow up the planet.
  • It's Personal: 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.
  • Jerkass Has a Point: When he calls out Superwoman on the fact that Just Following Orders is no excuse for what she's done and that in the end, she's as bad as he is.
  • Kick Them While They Are Down: His whole motif after he gains the Gold K heart. He powers down Kryptonians, then irradiates them.
  • Killed Off for Real: In the Post-Crisis, Pre-Flashpoint world he never recovered from his death in New Krypton.
  • Lack of Empathy: Reactron cares only about himself and how famous his killing is going to make him.
  • Made Of Titanium: Bullets bounce off of Reactron. So too, do most other attacks, including Kryptonian punches. It may not be the Nigh-Invulnerability of Superman himself, but there's no way around the fact that Benjamin Krull is a durable bastard.
  • Majorly Awesome: Formerly Major Benjamin Martin Krull, US Army, and still referred to as such by Lane and Luthor.
  • Man of Kryptonite: 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.
  • Not-So-Harmless Villain: 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.
  • Nuclear Nasty: Emits nuclear radiation, and with help from Luthor, can transform into a bomb.
  • Nuke 'em: Turns into a massive nuclear bomb.
  • Psycho for Hire: 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 The Joker.
  • Skull for a Head: A skull mask to be more precise.
  • The Sociopath: Reactron hits every requirement for the trope and most of those for the actual personality disorder, with his sadism, short temper, rapid mood swings, and total lack of conviction in anything beyond himself.
  • Sociopathic Soldier: 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.
  • Suicide Attack: 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.
  • Super Speed: 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.
  • Super Strength: 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.
  • Those Two Bad Guys: 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.
  • Underestimating Badassery: Everybody does this to him during New Krypton, with very bad results.
  • Ungrateful Bastard: 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."
  • You Killed My Father: 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.

    Reign (New 52)

The leader of the Worldkillers, a Quirky Miniboss Squad of Kryptonian-created Super Soldiers, and one of the first major enemies Supergirl faced in the New 52. 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- until Kara breaks it with her bare hands. Reign is not amused.
  • Blood Knight: Reign loves to fight, and she's very good at it.
  • Dark Action Girl
  • Distaff Counterpart: She's basically a female, rather more articulate Doomsday with a bit of Zod mixed in.
  • Evil Counterpart: Clearly positions herself as one in much of her dialogue to Kara. Especially since, if the hints as to her backstory are true, she's something of a daughter of Zor-el herself.
  • Flying Brick: Her powers are explicitly identified as flight, strength, and invulnerability.
  • Galactic Conqueror: 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.
  • Humanoid Aliens: She's roughly human/Kryptonian in appearance, except for her unnaturally pale skin, solid black eyes, and Pointed Ears. Her face is also shaped subtly different from a human's, with a slightly reptillian cast remniscent of Lord Voldemort.
  • Just Between You and Me: 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.
  • Implacable Woman: Thanks to her Flying Brick powers, she can take massive hits and just keep coming.
  • Master Swordsman: Reign's highly advanced combat training extends to swordsmanship, and she's lethal with her BFS.
  • Mysterious Past: Reign has serious memory gaps that she's trying to fill in as she tries to conquer the galaxy.
  • Not So Different: Feels this way about herself and Supergirl.
  • Obviously Evil: She's pretty sinister looking. For example, she has:
  • Pet the Dog: 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.
  • Super Soldier: She and her fellow Worldkillers were intended as the ultimate weapon by the Kryptonian scientists who created them.
  • Villain Exit Stage Left: 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...
  • We Can Rule Together: Makes Supergirl this offer at their first meeting. When Kara refuses, Reign decides she wasn't worthy anyway.

    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 Rogues Gallery, 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 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.
  • Anti-Villain: The duplicate Kara and Dolores straddle the lines between Type II and Type III.
  • Arch-Enemy: The Dolores Satan Girl was one to Ember, the Earth Angel of Fire who preceded Matrix and Linda.
  • At Least I Admit It: 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 Holier Than Thou. Although Dolores is also a child murderer, a racist, and considers Ember a creature because she was her slave. 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.
  • Back from the Dead: Dolores' first actual appearance was when she got revived by the Chaos Stream.
  • Even Evil Has Loved Ones: Dolores. 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.
  • Evil Counterpart: Pre-Crisis Satan Girl to Supergirl.
  • Evil Redhead: Dolores and S'tanicule.
  • Hate Plague: The crimson plague S'tanicule unleashes to make the world love her also turns people into bloodthirsty monsters.
  • Horned Humanoid: With Horny Devil, S'tanicule is the most satanic looking of all the Satan Girls.
  • Mad God: S'tanicule Gyrstress is the Brocian goddess of love and death.
  • Make Wrong What Once Went Right: 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. This is all to try and circumvent her daughter Rachel's eventual death, rebirth, and damnation, so this becomes a slight case of Set Right What Once Went Wrong.
  • Mama Bear: Dolores is a very evil version.
  • Morality Pet: Dolores' daughter Rachel.
  • Mythology Gag: When Dolores Pratchett originally became Satan Girl before her first death, she wore the Pre-Crisis Satan Girl's costume.
  • Pyrrhic Victory: In a way, Dolores got what she wanted. 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.
  • What Measure Is a Non-Human?: All the Pre-Crisis Satan Girl wanted to do was live, albeit at the expense of the lives of Supergirl and the female Legionnaires.
  • Woman Scorned: 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.
  • Would Harm A Child: Dolores Pratchett attained ungodly power after sacrificing children.
  • Ye Olde Butchered English: Dolores originally spoke like this, but when her enemy Ember switched places with Supergirl, she opted to drop the formal "thees" and such.

    Simon Tycho (New 52)
*spoilers* Click here  to see Simon's second form.

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. 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.
  • And I Must Scream: Supergirl defeats him in their second encounter by having Sanctuary encase him in crystal. He is possibly dead after Supergirl and Power Girl destroy Sanctuary after it turned evil.
  • Archenemy: In the New 52 for Supergirl.
  • Big Bad: for the Supergirl New 52 series.
  • Body Horror/Emergency Transformation: 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.
  • Rubber Man: His transformation gave him stretching powers, shapeshifting, and invulnerability.
  • Sharp-Dressed Man: He used to be one.
    • Loincloth: What he wears now. It shows off his new body quite well.
  • What Happened to the Mouse?: 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.
  • White Hair, Black Heart: Before his transformation.

    Superior Girl (Cosmic Adventures) 
AKA: Belinda Zee

A dark-haired, Kryptonite duplicate of Supergirl who called herself Belinda Zee, as she is "Linda Version B." Belinda is everything Linda Lee isn't. That is, she's popular and beloved by her classmates and teachers, and she's also a smug, petty, and manipulative bully, the complete opposite of Linda. So naturally, if Linda wants people to like her, Belinda wants Linda to be hated. Not necessarily a villain, she falls under Chaotic Neutral, and her emotional state of mind is considered very unstable. We later find out she has horribly low self esteem and actually wants to be nice, but feels totally backwards.
  • Affably Evil / Faux Affably Evil: Depending on how she's feeling.
  • Alpha Bitch: Although the only people she seems to bully are Linda and Lena Thorul.
  • Animals Hate Him: She gets mauled by Streaky.
  • Ax-Crazy: What she degenerates into.
  • Body Horror: 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.
  • Chaotic Neutral: Invoked as Word of God described her as such.
  • 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, as well as a dark mask.
  • Deadpan Snarker: Every word out of her mouth practically radiates with cynical snark. Not even being crystallized can turn it off.
  • Didn't Think This Through: She uses her "Superior Vision" on Streaky, and accidentally turns him into a sabertooth tiger.
    Superior Girl: That was not my best plan.
  • Even Bad Men Love Their Mamas: She considers Alura Zor-El to be her mother, and is genuinely heartbroken when what she thinks is Alura doesn't consider her to be her daughter.
  • Evil Counterpart: As far as an evil counterpart goes, Belinda didn't start out as a supervillain so much as she was an asshole who felt the need to wreck Linda's life. She even helps Linda in the fourth issue with nothing to gain. She doesn't become a straightforward villain until the fifth issue of Cosmic Adventures and only then because she's being manipulated.
  • Expy:
    • Of Bizarro. Though she's not as overt as most Bizarro counterparts go, simply in that she's an artificial creation that is the opposite of Supergirl in terms of morality without the chalk like skin, limited intellect, and messed up language skills. Had the creators been able to release the sequel series, Belinda's physical appearance would've become more Bizarro-like thanks to her transformation into crystal.
    • The writers also considered her as one to Veronica Lodge to match Linda's Betty.
  • False Friend: She once pretending she was Linda's best friend to drive a wedge between her and Lena.
  • For the Evulz: Why she makes Linda squirm so much. Other than that, this is exemplified in the third issue when she goes around empowering kids with the meteor fragments, knowing full well she's creating havoc.
  • Green-Eyed Monster: Secretly has a huge inferiority complex and hates Linda because she believes Linda thinks she's better than her.
  • It's All About Me: She interrupts a discussion being held between Linda and Lena and says they're talking about her. When Linda says they were discussing Superman, Belinda she says she automatically assumed they were talking about her because she's just the awesome.
  • Manipulative Bitch: When she's not flat out antagonizing Linda, she's acting overly kind and supportive as a front for a more underhanded scheme.
  • Pet the Dog: 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.
  • "The Reason You Suck" Speech: 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.
  • Sanity Slippage: Steadily becomes quite unhinged after she becomes Superior Girl.
  • Smug Snake: She's brainwashed into acting like a duck in the second issue, and in the fourth issue she gets attacked by Streaky. She's then turned into a statue by Mr. Mxyzptlk in issue six.
  • Stepford Smiler: Despite thinking she's completely awesome, she's really miserable and doesn't know why. She even admits at one point that she really does want to be nice like Linda, but feels her emotions are totally backwards.
  • Taken for Granite: And sentient.
  • Teacher's Pet: Although the teachers are all imps of the 5th Dimension who've been secretly using Belinda.
  • Tragic Villain: She goes from a smug asshole to a rampaging psycho to a poor, pathetic, and broken girl throughout the story.
  • Unwitting Pawn: Of Mr. Mxyzptlk.
  • Villainous Breakdown: 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."
  • Vitriolic Best Buds: There was shades of this in the fourth issue.
  • Woman Scorned: An odd variant. When she meets Supragirl, Linda's counterpart from an Alternate Timeline, Belinda flips and thinks she's being replaced, screaming she was the first, and therefor original, Supergirl doppelganger.
    Supergirl: If you're number one, and I was here first, what does that make me?
    Superior Girl: ZERO!

    Superwoman (Post-Crisis) 
AKA: Lucy Lane
Lucy as Superwoman

A mysterious woman wearing an S-shield whom Post-Crisis Supergirl encounters in New Krypton. She at first seems to be one of the heroes, but is eventually revealed as a villain when she not only attacks Supergirl, but saves Reactron from her, killing the supervillain's ex-girlfriend in order to cover up his survival. She is actually Lucy Lane, implanted in New Krypton as General Lane's spy.

    Xenon (Post-Crisis) 
The most mysterious enemy Supergirl ever fought, a powerful, demonic being who made vague hints about a previous battle with "a" Supergirl that left him trapped in a dying dimension. While still trapped in this dimension, he hunted down and murdered various Supergirls of different realities trying to find the one who originally fought him, and had a hand in the Pre-Crisis Kara Zor-El meeting Linda Danvers.

  • "It" Is Dehumanizing: Xenon will only refer to the Supergirl who defeated him as "She," with every other woman to wear the shield he refers to as "It."
  • Mysterious Past: We have no idea who Xenon was or where he came from before Many Happy Returns.
  • Serial Killer: Of Supergirls throughout the Multiverse and Hypertime. It's implied he's already killed a good number of them, and we're shown him murdering a slightly South American-esque Supergirl in Many Happy Returns.
  • Teeth-Clenched Teamwork: With his sometimes ally the Fatalist, a man who claims to be the Spectre's opposite.
  • Unknown Rival: It's implied the Supergirl he hates so much was Linda Danvers, but a Linda far older and more powerful. That Xenon is deliberately unclear as to which Supergirl he's talking about frustrates Linda and Kara.

Supporting Cast

    The Danvers (Pre-Crisis & Post-Crisis) 
Pre-Crisis Fred and Edna Danvers were the adoptive parents of Linda Lee/Kara Zor-El and Secret Keepers for her role as Supergirl. Post-Crisis Fred and Sylvia Danvers were the biological parents of Linda Danvers (Supergirl II) who had a much more traumatic time dealing with their daughter's super identity largely due to her merger with Matrix.

    Dick Malverne 
Pre-Crisis Dick Wilson was an orphan Linda Lee befriended until he was adopted by the Malvernes. Post-Crisis Dick Malverne is a new guy who moved to Leesburg.

    Ember and Rachel Pratchett (Post-Crisis)

  • Arch-Enemy: To the first Post-Crisis Satan Girl.
  • Burn the Witch!: Ember was burned at the stake for practicing witchcraft and satanism. When Rachel tried to save Ember, the two were engulfed by the flames and became an Earth-Angel.
  • Children Are Innocent: Rachel's sacrifice is what turned the two into an Earth-Angel.
  • Death Equals Redemption: What gets Ember, and by association Rachel, out of hell is Ember taking her place back from Supergirl instead of letting Supergirl die in her place.
  • Light Is Not Good: Ember and Rachel supposedly lived longer than the other Earth-Angels were known to do because Ember rarely exhausted her powers, remaining a somewhat selfish individual even after she was reborn.
  • Morality Pet: Rachel to Ember. Ember was a legitimately bad person, but she also legitimately loved Rachel and tried to save her when they were attacked by a group of dogs. Rachel is also this to her mother Dolores, a.k.a. Satan Girl.

    Lena Thorul (Pre-Crisis) 
AKA: Lena Luthor

Lex Luthor's younger sister, Lena Thorul's parents did their best to hide the reality of her brother's activities from her, claiming that her brother Lex had been killed in an accident.

  • Big Brother Instinct: Was the only person who could trigger Lex's.
  • Inexplicably Identical Individuals: She and Pre-Crisis Kara looked like clones. During the "Jungle Queen" storyline they traded costumes without anybody being any the wiser.
  • Locked Out of the Loop: At Lex's insistence. When Lena did find out who he was during an interview with him (and temporarily lost her mind, running off to Africa and becoming "Jungle Queen") Luthor staged an escape from prison so that he could expose her to flowers that erased unpleasant memories. She eventually found out for good in a storyline in 1981, and the two reconciled.
  • Morality Pet: To Lex, who went out of his way conceal their relationship from her, fearing that association with him would only hurt her. They eventually did reconcile.
  • Odd Friendship: With Supergirl.

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-New 52 Silver Banshee, see Superman's rogues gallery.
  • Evil Me Scares Me: Siobhan fears that the Silver Banshee will take over her body when it manifests.
  • Heroic Willpower: When fighting Red Lantern Supergirl, she's able to mostly stay in control as the Silver Banshee.
  • Irish Names: 'Siobhan' (pronounced 'Shiv-awn')
  • The Lad-ette
  • Make Me Wanna Shout: 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.)
  • Superpowered Evil Side: Her Silver Banshee form.
