* CrapsaccharineWorld: Metropolis.

* MostCommonSuperpower: All female superheroes are big-busted, especially Supergirl (being an adult, she's now so buxom as ''Comicbook/PowerGirl'').

** In two different flashback scenes, Supergirl and Batgirl show up with their original costumes.

* NeckLift: Kara does this to Lex. Several times. Justified because she has SuperStrength.

* RedEyesTakeWarning: Supergirl's eyes glow red when [[spoiler:Luthor pisses her off]] and she is going to kill him.

* SecretIdentity: Batgirl's secret identity as Barbara Gordon. Supergirl's is Linda Lee Danvers.

In an alternate universe in which Bruce Wayne was never Batman, and the infant Kal-El did not survive long enough to become Superman, the orphaned Barbara Gordon becomes Gotham's near-dictatorial protector, and Kara Zor-El -the Girl of Steel- teams with Lex Luthor and the Justice Society.

* BlueIsHeroic: Both main characters wear blue:

* BeyondTheImpossible: Kara performs a feat that no one thought possible: she manages to reason with Batgirl. Joking aside, it is a downplayed trope as Beyond the impossible is all about internal logic but "reason with someone" is not impossible.
* {{BFG}}: Batgirl has a gun which looks like a miniature rocket launcher.

* BoobsOfSteel: Supergirl is the strongwoman of the duo, and her breasts are bigger than Batgirl's.

* TheCape: Supergirl is nice, good-natured and trusting. And she always tries to make the right thing.

** Supergrrl is a composite of Supergirl and the Kon-El ComicBook/{{Superboy|1994}}.
* CoolBike: Batgirl owns a sci-fi bike which resembles a cross between a bike and the Batmobile.

* DefrostingTheIceQueen: A non-romantic example. Barbara was a jerkass who trusted no one, was constantly angry, was cold to other crimefighters and could be stubborn and irrational. However Kara managed to befriend her.

* DramaticIrony: Luthor saw himself as the man who opened Gotham. However it was ''Supergirl'' who opened Gotham. Even in universes where [[spoiler:he gets rid of Superman]], the Man of Steel and his family always manage to wreck his plans.
* {{Elseworld}}: It takes place in an universe in which Bruce Wayne was never Batman, and the infant Kal-El did not survive long enough to become Superman.

** Lex Luthor hates aliens. As far as he's concerned, killing a “xeno” isn't murder.
** Batgirl is very bigoted against parahumans. To be fair, though, she didn’t trust normal people either, and at the end of the story she appears to have gotten over her prejudice a bit.

* HoistByHisOwnPetard: [[spoiler:Luthor hired a hit-man to kill the Wayne family]]. Joe Chill murdered the Gordons instead, and their daughter prepared to take Luthor down. [[spoiler:He also made a fortune researching the cells of baby Kal-El whom he killed.]] However his super-powerful puppet turned against him right away when she found out about it.

* HotBlooded: Both Kara and Barbara count, being two emotional, passionate and stubborn women. Kara tends to be more impulsive and Batgirl is angrier, though.

* InSpiteOfANail: In spite of all of Lex Luthor's manipulations, Barbara Gordon becomes Batgirl, Kara Zor-El is sent to Earth and mentored by Wonder Woman. Then she becomes Supergirl, joins a super-team and makes friends with Barbara, just like in the mainstream universe.
* InterspeciesRomance: Subverted. Most of people think Supergirl and Lex Luthor are together, but their relationship isn't romantic at all (and after this story's events, it's non-existent).

* JustFriends: Kara insists that she and Lex are just friends despite of a number of rumors claiming otherwise.

* KryptoniteFactor: Supergirl feels weak and sick several times without knowing why… until Lex Luthor reveals that Kryptonite emits a radiation lethal to Kryptonians.

* LittleMissBadass: Barbara saved the Wayne family's lives when she was a little girl. After Joe Chill murdered her parents she picked her dad's gun, aimed at the man who had just slaughtered her family and ''ordered'' him freeze.

* MissionControl: Bruce Wayne acts as this, supplying Batgirl with information and advice from the Batcave when she's out on the streets.

** The media think Supergirl and Luthor are together. However Kara regarded him as a friend and surrogate father.

** One of the Barbara's books narrates how Batgirl captured Killer Moth. Killer Moth was the first villain encountered and fought by pre-Crisis Batgirl in Detective Comics #359.

* NobleBigot: Batgirl is very biased against parahumans ("No parahumans. No parahuman crime"? Really?), and she doesn't even trust super-powered crimefighters. Even so, she's a crimefighter who is committed to protect people. In her defense, she isn't as bad as Luthor (she merely wants parahumans out of her city. Luthor wants them dead and doesn't even regard them as humans), she at least respects Wonder Woman a bit and comes to call Supergirl a friend, and at the end she appears to have gotten over her bigotry a bit.
* NoSocialSkills: As disturbing as it sounds, this universe’s Barbara makes canon Batman seem psychologically stable in comparison. She is rude, harsh and tactless, and she doesn't work well with other people.

* ProfessionalKiller: In this universe, [[spoiler:Luthor]] hired Joe Chill to murder the Wayne family. However he was so incompetent that he murdered the wrong family and was arrested by a child.

* SayMyName: Supergirl states "Luthor" when she's about to attack him. Lex dispassionately notes that they are not longer on a first-name basis.
* SecretIdentity: Batgirl's secret identity is Barbara Gordon. Supergirl's is Linda Lee Danvers.

* ThouShaltNotKill: Zigzagged. Supergirl didn't like to kill… but when she discovered that [[spoiler:Luthor had done to her cousin]], she wanted to kill him. However Batgirl talked her out of it, stating that she's a hero and she mustn't drop to his level.
* TomboyAndGirlyGirl: Supergirl is the tomboy to Batgirl's girly girl. Kara is more masculine and aggressive, has a crew cut and wears trousers and sweaters. Batgirl is more female, has long hair, and wears dresses and jewelry.

* UpbringingMakesTheHero: Commisioner Gordon was a real cop. He swore to protect the good people of Gotham from criminals and took his duty very seriously. And so his daughter does.
* VillainWithGoodPublicity: Lex Luthor. He was a murderous, megalomaniac, heartless, xenophobic ManipulativeBastard. And yet civilians regarded him as a selfless and brilliant philanthropist, Supergirl thought he was a very good man, and the Justice Society were proud of calling him their friend and benefactor. When the truth came out, Supergirl feared that no one would believe her due to the power of his reputation.

** Supergirl regarded Luthor as a kind of father… until she learnt that [[spoiler:he murdered her baby cousin]].
* WellIntentionedExtremist: Batgirl's actions (virtually taking over Gotham, running it as her own private kingdom with spy eyes installed everywhere, banning parahumans from her city...) are questionable, but her goal is always protecting the good people of Gotham.

* AffablyEvil: Even when he's being a monster, Lex Luthor remains smiling, cool and polite.

* BewareTheNiceOnes: Supergirl is nice, kind, polite and good-natured. She even apologized to Batgirl for firing back after Batgirl insulted her and her family. Still, when she discovered that [[spoiler:Lex Luthor killed her cousin baby several years ago]], she wanted to kill him.

* BewareTheNiceOnes: Supergirl is nice, kind, polite and good-natured. She even apologized to Batgirl for firing back after Batgirl insulted her and her family. Still, when she discovered that [[spoiler:Lex Luthor killed her cousin baby several year ago]], she wanted to kill him.

** Dr. Midnite is female. (Although there [[AffirmativeActionLegacy has been]] a female Dr Mid''night'' in the mainstream universe.

* GenderedOutfit: Supergirl and Batgirl's teen costumes played it straight (Kara wore skirt and boots; Barbara wore high-heeled boots and her cowl let her long hair flow) but her adult costumes avert it.

* UpbringingMakesTheHero: Commisioner Gordon was a real cop. He swore protect the good people of Gotham from criminals and took his duty very seriously. And so his daughter does.

* CoolBike: Batgirl owns a sci-fi bike which resembles cross between a bike and the Batmobile.
