[[caption-width-right:294:The second best at what she does.]]

->''I am'' not ''a child! Stop calling me that!''
-->--'''X-23''', responding to [[{{Wolverine}} her father's]] constant mistake of referring to her by what she is.

X-23 is a character owned by MarvelComics, and created by Craig Kyle and his writing partner Christopher Yost. The character first appeared in 2003 episodes of ''{{X-Men Evolution}}''. She was adapted to the comic medium in ''NYX'' #3 (February, 2004).

A trained assassin, X-23, or Laura Kinney, was created by the Weapon X offshoot known as the Facility, or HYDRA, depending on universe, using a damaged sample of Wolverine's DNA. The damage was greatest on the Y chromosome apparently so Dr. Deborah Risman in the series and the similar Dr. Sarah Kinney in the comics eventually had brilliant idea to create [[OppositeSexClone a female copy instead]]. At last the 23rd attempt to clone [[{{Wolverine}} Weapon X]] was successful, thus X-23. However, Sarah Kinney states X-23 is technically a genetic twin rather than a true clone, making her Logan's sister.[[note]]Which is what a true clone actually is in RealLife, but not in comic books- as far as the comic is concerned the main difference is that she doesn't have Logan's memories, and in RealLife cloning that would never happen because ScienceMarchesOn and memories have been largely accepted to not be genetic.[[/note]] He later introduces her to her classmates at Xavier's this way, although they share more of a father-daughter relationship.

Originally created for the XMenEvolution cartoon as an alternative to giving [[WolverinePublicity Logan more focus]] or other Marvel Heroes, X-23 quickly became an EnsembleDarkhorse and was written into the comics, still scripted by her original creators. With a slight change in design (Supposedly to make her look more like Wolverine, but in the end she looks ''less'' like Wolverine, with the only notable comparison other than power being much paler skin and darker hair (which depends on the artist anyway, while also making her much more feminine), and a switch in background that was virtually the same, only even more DarkerAndEdgier.

While in the ''Evolution'' cartoon, it was never specifically said so, in the comics only her claws are made of Admantium, with her bones being normal. Because, instead of undergoing the same process as Wolverine, the scientists in the facility instead exposed her to massive levels of radiation to jump-start her healing factor at the age of seven, then forcibly removed her claws while she was wide awake and replaced them after being coated in Admantium. Yes, they did that.

She grew up being trained to be an Assassin, so that the Facility could sell her talents to the highest bidder. She grew up being emotionally and physically abused, in order to remove such weaknesses as emotion and self worth. However, Dr. Sarah Kinney, the one scientist who treated her like a child, tried to free her, but X-23 had been conditioned with a special 'Trigger Scent' that would forcefully throw her into a BerserkerRage, and X-23 uncontrollably killed the good scientist. In her dying words, Dr. Kinney named her Laura, as she had yet to be given a name.

After tracking down Logan, she was invited to join the X-Men, after a few years on the run, and soon grew a close relationship with some of the X-Men. However, it was retconned so that she only pretended to bond to them, and just saw them as inter-changable people, with only Logan being the one she would treat like a friend, and father. That changed after House Of M, where she was placed with some other students and eventually grew close relationships with fellow students Cessily 'Mercury' Kincaid, who had also been through a lot, Julian 'Hellion' Keller, who after being severely mistreated by him eventually became best friends, to the point she developed a crush on him, and Sooraya 'Dust' Qadir, who she gains a mutual respect for.

She later went on to join ''ComicBook/AvengersAcademy'' in the 23rd issue, forming an friendship with fellow social misfit Finesse [[spoiler: until a single utilitarian decision on Finesse part utterly destroys it]]. She later is captured by the villain Arcade to participate in his later Murder World in ''ComicBook/AvengersArena''.

She also made a surprise appearance in ''VideoGame/MarvelVsCapcom3''.

In 2013 she became a playable character in the Website/{{Facebook}} game ''VideoGame/MarvelAvengersAlliance''.

!!She provides examples of:

* AbsurdlySharpBlade: Same as Logan.
* AbusiveParents: Depending on your definition of "parents." [[CompleteMonster Zander Rice]] was one of the lead scientists involved with her creation and training, and the abuse he subjected Laura to was outright ''horrific''. Sarah Kinney, her biological mother, (surrogate womb and some genetic material) was ordered by the Facility to deny her an emotional connection, so was forced to shun her when Laura reached out to her. To her credit Sarah defied those orders whenever she was able, but this still led to much of her emotional damage. Then there's here handler, [[AxeCrazy Kimura]], who abused Laura as badly, if not ''worse'', than Rice. Seriously, it's saying something when as poor of a father as [[{{Wolverine}} Logan]] can be, (which he even outright ''admits'') he's ''still'' one of the ''better'' parental figures you've had.
** Sarah herself is revealed in ''Innocence Lost'' to have been abused by her father. A copy of the police report for one incident indicates that her mother and sister denied the allegations, and that Sarah herself would not talk to police about what happened. This led to Sarah cutting off contact with her family entirely, and she only reluctantly allowed her niece, Megan, to send her things. In fact, she didn't even ''know'' she had a niece until the girl was several years old.
** Kimura's FreudianExcuse is that her mother neglected her, her father abused her, and that she was subjected to a ''lot'' of bullying as a child. Her grandmother attempted to undo the damage, but by then it was too late and Kimura later takes it all out on Laura.
* TheAce: Her time with the New X-Men really just highlighted how unskilled and immature they were. it's really not surprising that she was the first person Cyclops recruited to his [[{{X-Force}} team]].
* AlternateUniverse: Like most Marvel Universe characters she has several:
** ''League of Losers'': A villain from the future uses historical data to kill all the well known heroes in the world. Only a handful of heroes who weren't in the historical records (making them "losers") survive. X-23 was one of those heroes.
** ''X-Men: The End'': A near future version of the character. Strangely, she not only appears to have an adamantium skeleton, but her muscle tissue appear robotic or techno-organic. This is never explained though.
*** It's not the first time Claremont wrote her as having an adamantium skeleton. He probably just didnt realise that wasn't the case.
** ''Artume-ruled reality'': In a temporary alternate reality created by Amazon Queen Artume where women rule the world, X-23 is known as Wolverine, and is one of the main members of the Avengers.
** ''Age of Apocalypse'': The daughter of Logan and Mariko Yashida who goes by the name Kirika is found in Mr. Sinister's lab in a container labeled "X-23". Most fans consider this a InNameOnly version of X-23.
** Her TV and video game appearances are regarded as Alternate universes as well.
* AlternateCompanyEquivalent: Cassandra Cain (AKA ComicBook/{{Batgirl 2000}}). Everything from their backgrounds(both raised as assassins), their lack of social skills, and their relationships with their [[{{Wolverine}} father]]/[[{{Batman}} mentor]] is very similar.
** However, Laura is a DarkActionGirl, while Cassandra is TheCape (in personality, at least). Laura has mutant powers, while Cass is a BadassNormal bordering on CharlesAtlasSuperpower. They're very similar, but they also have fundamental differences between them.
** You can also make this connection: a female version of a popular character is introduced in an AnimatedAdaptation. She proves so popular that she becomes a CanonImmigrant. Now, did I just describe X-23 or HarleyQuinn?
*** Not to mention that some people claim Wolverine is the Marvel equivalent to Batman...
* AndThisIsFor: When Rice begins the surgery to remove Laura's claws to be coated in adamantium without anasthesia, he tells her [[RevengeByProxy "This is for my father."]]
* AntiHero
* ArchEnemy: Kimura, her former Handler and the one who dealt her abuse from an early age. Kimura has Density Control, giving her immunity to X-23's adamantium claws since she can make her skin denser then the metal itself.
* ArtShift: Ocasionally covers will draw her slightly beefy and resemble a slightly older version of her Evolution design, only for the story to use her more common skinny goth look.
* AscendedExtra: Originally just a minor X-Men Evolution character used as an excuse so the writers didn't have to expand the 'Evo-Verse' to include more heroes, and so Wolverine didn't get a chance to hog the spotlight. Now look, she's one of the few X-Men to get her own page.
* AwesomenessByAnalysis: Combined with SherlockScan below: Whenever Laura walks into a room, her brain ''immediately'' calculates the best means of killing everyone inside it.
* {{Badass}}
** BadassAdorable: Especially as a little girl.
** BadassBookworm: Not the same degree as some, but Laura is incredibly gifted intellectually and received an extensive (albeit narrow) education during her training.
* BadlyBatteredBabysitter: She has to babysit the [[ComicBook/FantasticFour Richards kids]] in the most recent arc. Even though the kids summoned a huge dragon and got kidnapped by an intergalactic pack rat, she managed to rescue and get them in their [=PJs=] before Reed and Susan got home.
* BareYourMidriff
* BerserkButton: A few. Don't hurt Logan (as Bishop learned during a training exercise), Julian (as Lady Deathstrike learned), or pretty much anyone she likes (as Kimura learned). Also, in Evolution, she gets very pissed if someone calls her a child or a kid, as it reminds her of the childhood she didn't have. Also the "Trigger Scent" is a very literal but olfactory version of this.
* BlessedWithSuck
* BondOneLiner / IronicEcho: After [[NoHoldsBarredBeatdown beating Zander Rice within an inch of his life]] at the end of ''Innocence Lost'', Laura looks over her shoulder and calls him "Animal" as she leaves him to die when the Facility's base explodes. Throughout the story Rice referred to Laura as an animal to her face.
* BodyHorror: Her claws were ''forcibly removed'' from her body without any attempt at anesthesia so they could be coated in Admantium.
* BreakoutCharacter: Was arguably the main character of New X-Men, has had a number of miniseries and now an ongoing series, and is now almost always included in Team images.
* BrokenBird
* BrutalHonesty
* CainAndAbel: With {{Daken}}.
* TheChosenOne: She was once CaptainUniverse's vessel. More recently [[spoiler: a mark associated with Captain Universe appeared on her hand suggesting a more permanent association.]]
* CoolBigSis: Was one to her cousin Megan, and Jubilee is one to her.
* CoolOldGuy: What she considers Gambit, even though he's no more than 15 years her senior.
* CombatPragmatist: She ''was'' trained to be the perfect assassin after all.
* CoversAlwaysLie:
** ''X-23: Target X #5'': The cover shows Kimura triumphantly holding two of X-23's claws, having apparently just ripped them out of her hand. The closest thing to this in the actual story is X-23 cutting off her own hand (and promptly reattaching it) to escape Kimura.
** ''X-Force #18'' (2009): The cover shows X-23 in a tank undergoing the process of her skeleton being laced with adamantium. Never happens.
** ''X-Force #20'' (2009): The cover shows the team (minus X-23 herself) being attacked by half a dozen X-23 clones. Not only are those clones non-existent, the team has minimal interaction with the original X-23 during the story, which is focused mainly on her.
* CreepyChild: How Kiden Nixon, and frankly the rest of the group she falls in with, see her in ''NYX''. Pretty much all of them use this exact description.
* CursedWithAwesome: Made painfully clear with Laura's private thoughts in ''AvengersArena''. Whenever Laura walks into a room, she [[SherlockScan immediately calculates the threat level of everyone inside it]] and determines the best method of killing all of them. This is great when she's dealing with people who want to make her dead in turn, however ''she can't turn it off''. This means she even formulates plans ''for killing her friends and loved ones''.
* DarkActionGirl
* DarkAndTroubledPast
* DarkIsNotEvil
* DeadpanSnarker
* DeathSeeker: Her constant cutting of her wrists as well as her agreement to take part in X-Force seems to confirm this. Made pretty obvious when she asks Jubilee to kill her if she succumbs to the trigger scent after tempting Jubilee with her blood ''just to see if she would kill her''.
* DefusingTheTykebomb[=/=]IAmNotAGun: She is struggling to find an identity other than "living weapon."
* DependingOnTheArtist: X-23 is sometimes drawn with dark skin like her original design in Evolution.
** Her bust sizes changes too, as does her height.
* DependingOnTheWriter: In the X-Books, Laura is established as having a HealingFactor superior to Wolverine's (see below). However once she gets to ComicBook/AvengersAcademy, Hank Pym warns Hazmat that "her healing factor isn't as strong as Wolverine's". This may be a mistake on his part (assuming that her youth would mean her powers were not fully developed), but he's a genius, one of head teachers at the academy and Wolverine would likely have given the faculty a full rundown of her powers and problems when he dropped her off. The writer later admitted to the mistake on his part in the letters pages.
** Laura's speech patterns also tend to vary depending on who is writing her. She's generally accepted to [[SpockSpeak speak very formally and not use contractions]], and in ''The Killing Dream'' this is even used as a plot point: [[spoiler: when Miss Sinister attempts to ambush Gambit after [[VoluntaryShapeShifter disguising herself as Laura]], part of the GlamourFailure is she uses several contractions when speaking, as well as behaving in a generally un-Laura-like way. Though Gambit [[GenreSavvy knows Sinister too well to have been fooled in the first place]].]]. However she ''does'' use them in some of her other appearances, such as ''NYX'' and her own origin book, ''Innocence Lost''.
* DistaffCounterpart: To {{Wolverine}} and {{Daken}}. The writers explicitly designed her with the question in mind: "If Wolverine were the male of the species, what would the female be like?" They decided that she would be leaner so she could chase prey like a lioness and would have two claws on her hands and one on each foot so that she could climb trees and puncture the gut of any predators who managed to tackle her.
* EvilCounterpart: Daken, in a way. Both are genetic children of Logan, both tend to only use two of their claws and save the third for special attacks, both have messed up pasts. They have a mutual respect for each other in part because they are so alike.
* {{Expy}}: Hmm... a young, royally screwed up, super-powered, dark haired, teen girl who utilizes WaifFu? Applies equally to X-23 or [[{{Firefly}} River Tam]].
** The two characters are so similar that many fans are already demanding that any possible live-action adaptation of X-23 be played by SummerGlau.
** Also, {{Hanna}} is more or less what a real world version of X-23 would look like.
* FastBallSpecial: Laura and SpiderMan have their own version of this.
* ForcefulKiss: Laura was on the receiving end from her (sort of) boyfriend Hellion in ''X-23 #19''. She didn't enjoy it.
* GenerationXerox: Just like her daddy, she had a reciprocated but incredibly complicated love for a powerful psychic mutant.
* GoodThingYouCanHeal: How many cute teenage girls get burned beyond recognition repeatedly?
* {{Goth}}: Laura's manner of dress often has a goth influence, ''particularly'' during the time she spent as a prostitute during ''NYX''.
* HappilyAdopted: By Wolverine. It was [[CrowningMomentOfHeartwarming sweet]].
* HealingFactor: Hers is even more powerful than Wolverine's, since she only has adamantium in her claws rather than her whole skeleton, and Logan's is slowed by constantly having to fight adamantium poisoning. Her mother speculated that Laura's ability to heal would be similarly slowed if her entire skeleton was bonded as well.
* HeterosexualLifePartners: With Jubilee.
* HookerWithAHeartOfGold: Laura in the largely forgotten NYX series, although she is a "specialist" who uses her claws to cut masochistic clients. This isn't mentioned often in her recent history, coming up in her 2010 one-shot and a couple issues of her solo series.
* HollywoodScience: The process in which X-23 was cloned is impossible. But in a universe where humans can fly, shoot lasers out of their eyes and talk to Gods on their cell phones, it's hardly significant.
** Arguably she's more believable that a lot of comic book clones since they often show up with the same appearance, age, personality, and memories as their "parent".
* HollywoodGenetics: Her eyes are often drawn as green, despite the fact that her one source of DNA, Wolverine, doesn't have green eyes.
** Her eyes are those of Dr Sarah Kinney, the scientist who created her. It was said in Target X that Sarah Kinney used some of her own DNA to stabilise the sample from the original Weapon X programme.
** Clones of animals in real life can have differing coloration from their "parent". RealityIsUnrealistic is in play here.
* HugeGirlTinyGuy: Well, not exactly, but she certainly goes against the norm by being 3 inches taller than her SpearCounterpart.
** DependingOnTheArtist: Her height vs. Logan's height varies a lot. Mostly due to how Logan's height changed since HughJackman played him in the movie (Logan started at 5'2", spent a lot of time at 5'5", and now is sometimes drawn actually ''tall''.) During New X-Men, Laura was half a head shorter than Logan.
* IJustWantToBeNormal: She would like to be, but doesn't really know how. During her time with the New X-Men, she was about as close as possible for any X-Man to be. She was actually going to school with other kids her own age for a short time.
** Heavily foreshadowed in her origin story when her mother would read her ''Pinocchio''.
* InnocenceLost: Laura's origin story is even ''called'' this, and shows in brutal detail the cruelty inflicted on her by the Facility to strip away her humanity and turn her into an emotionless killing machine. They ultimately failed, but still managed to inflict quite severe damage that she still struggles to recover from.
* IntergenerationalFriendship: With Gambit.
* ItsNotYouItsMyEnemies: She was developing a good relationship with her maternal aunt and cousin, so getting as far away from them as she could was the best thing she could think of doing for them.
** Well, it didn't help that Kimura was chasing her and had already tried to kill them.
* JackBauerInterrogationTechnique: Laura is fond of this, usually to the horror of her teammates.
* TheLancer: To Wolverine in {{X-Force}}.
* LittleMissBadass: In X-Men:Evolution, Laura defeated ''all'' of the X-Men, despite being half the age of most, if not all, of them. Although this version did have her skeleton laced in adamantium and the element of surprise (and even the ones who knew they were being attacked had no idea ''who'' they were up against and had no way to fight back), it's not likely Wolverine himself could do this.
** Cannonball even states to Logan, "Not even you could take us all out." She does, and later pulls a BatmanGambit to be captured by HYDRA before making everyone think she died destroying them.
* MookHorrorShow: You know the monster that ''[[ImplacableMan might]]'' go down with enough firepower, but will gut the poor slob closing in for a coup de grace and/or track down those who leave it for dead? This is her, only add assassin skills to the mix.
* MoralityPet: Acts as one for Wolverine. Gambit as well in her self titled series. Hellion can be considered hers during their time with the New X-men.
* MostCommonSuperpower: Sometimes averted, sometimes played straight, DependingOnTheArtist.
* MsFanservice: You wouldn't think so, until you look at the way she dresses.
* MyGodWhatHaveIDone: Laura's got a body count that's almost certainly in the triple digits, but the only people she's ever shown any regret or sadness about killing at the time was her mother Sarah and her martial arts instructor.
* NoHoldsBarredBeatdown: Laura delivers a brutal one to Zander Rice at the end of ''Innocence Lost''. Yes, she could have easily killed him with her claws, but after disabling his gun she put them away to beat the ever-loving shit out of him in return for everything he's done. Her mother just gave her a mission to kill him. Laura pummeling him for about nine minutes[[hottip:*:Based on Laura's mission timer. Her fight with Rice begins at about 11:00 on the clock, and ends at about 01:00]] straight? ''[[TheDogBitesBack Payback]]''.
* NoSocialSkills
* NotSoDifferent: With Vampire Jubilee. Jubilee and Laura realize they have much in common, with X-23 having to struggle with finding herself and the trigger scent and Jubilee struggling to control her newfound blood lust. They get along [[HeterosexualLifePartners really well though]].
** She has this with {{Daken}} as well: Technically brother and sister, both raised by some very, ''very'' bad people, but while Daken embraces what Romulus made him, Laura desperately wants to be something more than just a weapon and killer. Nonetheless, their similarities give them a fair bit of mutual respect towards one another, and Laura has not inherited Daken's hatred for their [[{{Wolverine}} father]].
** Also with Kimura, of all people. Both suffered severe physical and emotional abuse in their past that's largely shaped and defined who they are now. Both also only had one or two people in their lives when they were young who showed them love and kindness, and attempted to repair the damage that was done. The difference is that Kimura became an AxeCrazy psychopath who uses the abuse and bullying she was subjected to as an excuse to do it to others herself, while Laura is making an ongoing effort to heal.
* OfCorsetsSexy: If she's not in a midriff-baring tank top, (or even just what amounts to a ''bra'' or bikini top) chances are Laura is wearing one of these.
* [[OneManArmy One Girl Army]]
* OppositeSexClone: Of Wolverine.
* PintsizedPowerhouse: Not exactly the strongest physically, but is quite deadly for someone whose actually ''shorter'' than ''Logan''.
* PleaseWakeUp / PleaseDontLeaveMe: At the end of ''Innocence Lost'', {{X-23}} kills her mother in a chemically-induced berserker rage, just as they destroy and escape the Facility that bred her. As Sarah Kinney dies and tells Laura that she loves her, for a moment she stops being a weapon and is just a little girl again, [[TearJerker hopelessly begging, "please don't leave me,"]] even after it's clear that Sarah has already died from her wounds.
* ThePowerOfFriendship: This is how she overcame the trigger scent in X-23# 12, something she's ''never'' been able to do on her own.
* ProfessionalKiller: This is what X-23 was raised to be. Not wanting to let that define her life, she's since changed her approach to be more in line with X-family ideals, but her complete ruthlessness makes her at times a more efficient killer than even Wolverine.
* RaceLift: In the AgeOfApocalypse universe, X-23 is half-Japanese due to having Mariko Yashida as her mother.
* RavenHairIvorySkin: DependingOnTheArtist, but in the comics she's generally depicted as having fair skin and black hair.
* RedEyesTakeWarning: It means she's affected by trigger scent and you might want to do more than just "take warning." During her most recent episode in Paris, her eyes were actually ''[[GlowingEyesOfDoom glowing]]''.
* SelfHarm: She habitually cuts herself on the wrists and forearms with her claws, and is first shown to engage in this behavior [[spoiler: as a reaction to being forced to kill her sensei as a test of the trigger scent]]. Laura can fall under ''all'' of the reasons for cutting noted on the trope page, and one issue of her solo series suggests she may even be inflicting fatal injuries on herself: An employee at a hotel where she was staying with Gambit reported to his manager that it appeared as if someone attempted to commit suicide in a bathroom she just left. Her HealingFactor prevents her from dying from her wounds, however, and completely heals the resulting scars.
* SelfMadeOrphan: Not by her choice. She ended up killing her mother due to the Trigger Scent put on her.
** It was revealed in a recent flashback that Wolverine officially adopted her as his daughter.
* [[SexGod Sex Goddess]]: During her time as a hooker she was said to be "the best at what she does".
* SherlockScan: Whenever Laura walks into a room, her brain ''immediately'' begins to analyze the situation and everyone in it, performing threat analysis, formulating multiple attack plans, and calculating the best method with which to kill ''everyone in the room''. Her thoughts in ''AvengersArena'' reveal that ''she can't turn it off'', so she even does this to her friends!
* ShootTheDog: Forced to do this ''literally'' by the Facility as part of her BreakTheCutie TrainingFromHell. When they decided Laura still had too much empathy for others, she was given a puppy with orders to kill it within a set amount of time and was then left alone to carry it out. She played with it instead, and when her handlers returned to find the puppy still alive threatened ''to torture it'' as punishment for Laura failing to follow orders, before relenting an offering her another chance.
* SpockSpeak: Laura has a very rigid, measured way of talking; among other things, she doesn't use slang words and has never once used a contraction.
** Though it's the accepted portrayal of the character, it ''does'' [[DependingOnTheWriter vary from writer to writer]], however.
* {{Stripperiffic}}: Lately her outfits have been pretty tame, but in the past she wore outfits like [[http://media.comicvine.com/uploads/8/83789/1719139-x23thetarget_2_super.jpg this]], [[http://media.comicvine.com/uploads/0/77/245831-79051-x-23_super.jpg and this]]. And sometimes absurdly provacative outfits like her [[http://i237.photobucket.com/albums/ff148/Clerk57/Laura-1.jpg school girl outfit]].
* StrangeGirl: To put it in perspective, one of the easiest people for her to relate to is a ''vampire''.
* SuperSenses: Much like Wolverine himself
** Hers are better, or better trained. She could smell a man was lying about killing Wolfsbane when Logan couldn't (not that he believed her). Since their enhanced senses are a byproduct of their HealingFactor, this may be because Laura's is more powerful.
* TrainingFromHell: Her back story in "Innocence Lost".
* TroubledButCute: Cute? Her dress tends to be quite {{Fanservic|e}}y, usually involving tight, low-waisted pants or short skirts with [[BareYourMidriff short tops]]. Troubled? Hoo boy.
* TroublingUnchildlikeBehavior: Laura's first assassination was at age 9. She was immediately put to work by the Facility afterwards, and by 16 she's an accomplished enough killer to worry ''CaptainAmerica''. {{Justified| Trope}} since she was bred and raised from birth ''specifically'' to be a LivingWeapon, but her utter ruthlessness and cold detachment makes her an even better killer than {{Wolverine}}. It's mildly subverted in that she doesn't ''want'' to be a weapon, but it nonetheless comes completely naturally to her.
* TykeBomb: ''Literally'' conceived as such.
* TheSoulless: In ''The Killing Dream'', a demon attempting to recruit Laura to his service tells her that as a clone, (and because of all the death she has caused) she has no soul, and drags her into a BattleInTheCenterOfTheMind to give her a chance to prove him wrong. [[spoiler: Laura encounters her inner self, who reveals that she wasn't ''born'' an emotionless killing machine, but that it took the conscious effort of the project to break her. This revelation gives Laura the power to defeat the demon, however she remains in doubt over how much of his taunting was the truth afterwards. When Miss Sinister later attempts to steal her body, Laura questions her about having a soul, but Sinister is unable to answer and admits it is something she has given little thought.]]
* TheUglyGuysHotDaughter: OppositeSexClone, actually, but that just makes it even ''more'' noticeable.
* UnlimitedWardrobe: It seems as though she has so many short tank tops and skinny jeans that sometimes she doesn't even need a uniform. The way her foot claws work means she must have a ton of shoes stashed somewhere too.
* UnstoppableRage: The trigger scent causes this.
* VitriolicBestBuds: With Hellion. Laura and Jubilee started out like this before becoming HeterosexualLifePartners.
* ViolentlyProtectiveGirlfriend: Lady Deathstrike found this out the hard way.
-->'''X-23''': You were dead the second you touched Julian Keller.
* WaifFu
* WeakButSkilled
* WhatIsThisThingYouCallLove: Laura was brought up as an assassin and only her mother and sensei showed her any compassion or kindness during her childhood. But nobody ever told her about boys. As a result, she has no clue what's going on when she finds herself attracted to Hellion.
* WillTheyOrWontThey: With Hellion, since both are initially unable to deal with their growing attraction to each other.
** [[spoiler: At least as of the end of her solo series, they won't.]]
* WiseBeyondTheirYears: Due to never really having a childhood.
* WolverinePublicity: Why she was created in the first place.
** She really fits the trope now, showing up in multiple books (Her own ongoing, Avengers Academy and Venom).
