[[quoteright:120:http://static.tvtropes.org/pmwiki/pub/images/ci_19387_1364477468.png]]
->''Voiced By Creator/WakanaYamazaki (JP)/ Creator/ColleenClinkenbeard (EN)'', Erika Araujo-Robledo and Angelines Santana (first Latin American Spanish dub), Mayra Arellano (movies 1, 2 and 18 onwards plus first Anime/LupintheThird crossover and ''Manga/MagicKaito 1412'', Latin American Spanish dub) Jessica Toledo (third Latin American Spanish dub), Berta Cortés (first European Spanish dub), Diana de Guzmán (second European Spanish dub, first part), Creator/CarolinaTak (second European Spanish dub, second part and movies), Creator/NuriaTrifol (third European Spanish dub), Tomoka Kurokawa (2006 Live-Action Drama Actress), Shiori Kutsuna (2011 Live-Action Drama Actress)

Shinichi's childhood friend and love-interest. When Shinichi shrinks and takes on the name Edogawa Conan, she takes on the big sister role and looks out for Conan like if he was any other little kid. Ran also wishes for her parents to get back together and tries but fails time and time again at forcing a set-up between the two.

She also happens to be well-trained in karate at the expense of anyone trying to take advantage of her.

[[ThemeNaming Mandatory name note]]: The entire name came from [[http://en.wikipedia.org/wiki/Maurice_Leblanc Maurice Leblanc]], creator of Literature/ArseneLupin, through the Japanese reading ''Moori''tsu Rubu''ran''.

DubNameChange: Rachel Moore.
----
* TheAce: Ran is a karate champion, an excellent cook, gets good grades, popular with the opposite sex, and is a well liked person.
* ActionGirl: She's got a good record for getting herself out of scrapes with criminals, being a national karate champion.
* ActionGirlfriend: {{Subverted|Trope}}. She is Shinichi's LoveInterest ''and'' an ActionGirl but he's stuck as Conan and therefore, whenever she goes MamaBear on anyone that threatens him, she doesn't know she's actually defending her "not"-boyfriend.
* AffectionateNickname: "Angel" by Vermouth.
* AgeLift: {{Downplayed|Trope}}. The difference isn't too extreme but still noticeable. In the manga, Ran is 16; in the anime, Ran's age is increased by a year.
* AllLovingHeroine: Ran is a '''genuinely''' NiceGirl, who has enough compassion for murderers (well, some), and will never hesitate to save someone's life. Criminal or not.
* AlmostKiss: In canon; she does score a kiss in the non-Canonical Movies.
* AnimalMotifs: Haibara states Ran would be similar to a dolphin. A description that matches Ran perfectly due to her approachable nature, cuteness, and loyalty.
* BadassAdorable: Adorable all the time and can always kick ass.
* BadassInDistress: More in {{The Movie}}s. In ''Captured in Her Eyes'', [[spoiler: after spending almost the while movie as a quiet [[TheOphelia Ophelia]] afflicted TraumaInducedAmnesia, as soon as she recovered her memories she beat the ''shit'' out of the BigBad, who caused it by shooting Sato almost to death in front of her.]]
* BarbieDollAnatomy: Ran in some of the OP and ED animations-shown nude either in full body (without anything showing), or implied by showing a close-up with bare shoulders. Presumably intended to imply Ran's [[{{Woobie}} vulnerability]] from being kept apart from Shinichi for so long.
* BecauseYouWereNiceToMe: Her friendship with Shinichi began after he defended her from bullies when they were children.
* BelligerentSexualTension: With Shinichi. They tend to argue from time-to-time, but they have romantic feelings for one another.
* BerserkButton: Ran gets quite peeved when she thinks that Shinichi may be committing infidelity (even though they're not in a relationship).
* BewareTheNiceOnes: Ran is one of the kindest, bravest, and selfless characters in the WHOLE franchise. You ''don't'' want to make her use her karate skills on you.
* BigSisterInstinct: Don't try to kill Conan with her in the vicinity.
* BirdsOfAFeather:
** Despite outwardly different personalities, she and Shinichi share many traits -- Both [[AllLovingHero have a deep respect for life]], [[ChronicHeroSyndrome a penchant for rushing to help someone in need]], are the [[TheAce the aces in their respective field(s)]], [[NervesOfSteel remain calm in dangerous situations]], and [[UndyingLoyalty have a deep loyalty to their friends and family.]] The two of them are also incredibly stubborn in their ways, have a strong sense of justice, play a sport they enjoy (Ran – karate, Shinichi – soccer), play an instrument (Ran – piano, Shinichi – violin). On an amusing note, both have {{Improbable Hairstyle}}s (see individual sections for explanation) and a family situation of some kind (Ran’s parents are separated and Shinichi’s parents moved to Los Angeles when he was 14). Also, both also have a number of admirers of the opposite sex.
** With Kazuha -- Practitioners of a martial art (karate for Ran, aikido for Kazuha), afraid of the supernatural, [[FriendToAllChildren love of children]], are {{Dude Magnet}}s but [[SingleTargetSexuality only have eyes for]] [[ChildhoodFriendRomance their childhood best friend]]. And even though they can be exasperated by their love interest's detective work and occasional jerkish side, both think that whenever their "not" boyfriends solving cases look cool when doing so and [[SingleWomanSeeksGoodMan admire them for their better qualities as well]]. Also, both of their fathers are connected to some kind of detective/police work.
* BoobsOfSteel: She's quite the ActionGirl, and possesses rather large breasts. [[GagBoobs Which once in a while are the subject of visual gags.]]
* BornLucky: Ran has ''absurdly'' good fortunes playing luck-based games like Poker or Mahjong. First seen when she goes into a mahjong parlor where her father Kogoro is gambling, very upset because he took Conan with him... then she gets interested in the game itself... and in the next scene she has fleeced her dad ''and his companions'' out of all their "prizes". (And then the owner of said parlor, who doubled as a loan shark, appears dead...) Another case started with her aiming to win the ''second'' prize in a raffle, which was a family trip to the beach. Conan was all "I don't think you'll win"... Cue to the next panel, with Ran happily telling Kogoro about the trip she won and a terrified-looking Conan next to her.
* BrokenPedestal: With assistance from Shinichi/Conan, Ran exposes the murder culprit in the "Ski Lodge Murder" case is her former elementary school teacher, Akiko Yonehara; this also meant that her teacher was also the one who attempted to strangle Sonoko. At the end of the deduction, she cries while hugging Conan in despair.
* CannotSpitItOut: Even though Ran is in love with Shinichi, she has repeatedly failed to convey her feelings because she suddenly becomes self-conscious.
* CharacterDevelopment: In earlier stories, she would become violently suspicious if she thought Shinichi was philandering, although more recently his confessions (in the "Holmes' Revelation" Arc) have led her to trust his intentions.
* CharacterizationMarchesOn: Early-manga Ran is noticeably more HotBlooded and petty than her later AllLovingHero characterization; in the "Art Museum Murder Case", Conan/Shinichi implies she ''regularly'' busts out karate moves on furniture when she doesn't get her way.
* CharlesAtlasSuperpower: Through nothing but the karate practice she leads at school while otherwise leading a normal girl's life, Ran Mouri can take out a small army of hired thugs and knock out armed criminals. She can apparently [[DodgeTheBullet even do the bullet thing,]] at least in one of the movies. [[MST3Kmantra Don't think about it too hard.]] It could also be a slight case of ItRunsInTheFamily. At least home schooling has been mentioned, and both Kogoro and Eri know their Judo pretty well.
* ChefOfIron: Frequently noted to be an amazing cook and is a karate champion.
* ChildhoodFriendRomance: With Shinichi. They've known each other since pre-school and are each other's canonical love interest.
* ChildhoodFriends: Ran has known both Shinichi and Sonoko since they were four. [[ChildhoodFriendRomance Her relationship with the former grew beyond friendship]].
* ChildrenRaiseYou: For Kogoro, her ManChild father. She acts more like his mother or wife than his daughter.
* ChronicHeroSyndrome: Ties in nicely with her NiceGirl personality and [[AllLovingHero All Loving Heroine]] philosophy.
* ClingyJealousGirl: Ran is a very sweet and kind NiceGirl who borders on AllLovingHeroine... unless she's given a reason to be jealous of a girl getting close to Shinichi. Then she gets ''very'' jealous. Thankfully, her niceness tends to shine back through.
* CluelessDudeMagnet: Ran is typically unaware of her own attractiveness, and usually remains oblivious when men try to flirt with her, often to Sonoko's exasperation, who believes her wait for Shinichi to be hopeless.
* CoolBigSis: Acts like a kind, fun, and protective older sister figure to Conan, Ai, and the Detective Boys.
* CulturedBadass: Ran appreciates the fine arts and has been noted to have a great singing voice. She can also play the piano.
* CuteBruiser: Plays karate on the national level. Dere-dominant {{Tsundere}}. For proof: there's an episode where [[spoiler:Ran (Assisted by Makoto, Sonoko's GeniusBruiser boyfriend) [[LadyOfWar took out 50-60 gang members, many armed with katanas]].]] It took 12 minutes, and not a hair was out of place.
* DaddysGirl: Kogoro may exasperate Ran with his constant drinking, womanizing, and over all laziness, but if you call him a lousy detective or take away his business, she'll [[http://imageshack.us/f/545/rano.jpg/ do this.]] On the other hand, Kogoro is pretty much an OverprotectiveDad and [[CrouchingMoronHiddenBadass one of the best ways to make him act competent]] is to [[PapaWolf look at his little girl in anything similar to a wrong way.]]
* DamselOutOfDistress: Her waifish figure and cute face make Ran a frequent target of criminals seeking some kind of human shield. [[https://youtu.be/vy8jE0bbXEk?t=81 Scenes like this one]] prove why this is a ''terrible'' idea.
* DemotedToExtra: In the 20th movie, Ran only has a handful of screen-time moments. A sharp contrast to how much she appeared in the previous movies.
* {{Deuteragonist}}: To Shinichi/Conan's protagonist.
* DudeMagnet: Like her "detective boyfriend", Ran has received a '''very''' high amount of attraction from the opposite sex men and so far one girl being attracted to her.
** In many of the cases she's involved in, at least one man has tried to flirt with her.
** There's [[TheHero Shinichi]], who she [[SingleTargetSexuality only has eyes for]]. In fact, Shinichi has [[LoveAtFirstSight loved her from the moment they met in pre-school.]]
** During the "Sonoko's Dangerous Summer Story" case, Sonoko comments on how most of the men that came to them and Conan only came because they wanted to flirt with Ran.
** [[spoiler:[[NewTransferStudent Eisuke Hondou]] [[LoveAtFirstSight fell for Ran the first moment he met her]] and wanted to take her to America with him.]]
** [[KendoTeamCaptain Okita]], Heiji's kendo rival, hits on her the first time they meet.
** [[PhantomThief Kaitou Kid]] at one point tried to kiss (and grope) her in a non-canonical movie.
** In a non-canon OVA, [[HospitalHottie Dr. Araide]] apparently asked for her hand in marriage, but it turned out to be Conan's dream.
* EstablishingCharacterMoment: Within a page or two of her introduction in the very first chapter, we see her ''crack a concrete pole'' with a single punch. Ran Mouri is ridiculously strong. Ok, duly noted.
* EvenTheGirlsWantHer: If we take [[BiTheWay Sera]]'s "she's just my type" and Sonoko's AmbiguouslyBi moments seriously.
* FirstLove: To Shinichi, he has been in love with since they were both ''four''.
* FlowerMotifs: In ''"The Nocturne of Red Murderous Intent Part 2"'', Conan brings Ran a bouquet of blossoms, specifically peach blossoms; peach blossoms represent happiness of love. It's also related with longevity, when reading the kanji for “hundred” 百 (momo) the same way as the one for "Peach tree" 桃 (momo). It could also mean everlasting love, and since it's a spring flower, it's also associated with weddings.
* FriendToAllChildren: She's a nice person in general, but especially the Detective Boys all like her very much. Ai is a little more skittish at first, being somewhat jealous of and intimidated by her popularity; she later warms up to her too when at some point [[spoiler: she reminded her of the recently murdered Akemi]]. There really doesn't seem to be a child in the world that she could not get along with.
* GeniusBruiser: {{Downplayed|Trope}}. There's more emphasis placed on her amazing karate skills than her smarts. However, in the moments where she does solve a case, Ran displays a very good memory for history, and has used her knowledge to contribute to an investigation cases more than once.
* GirlyBruiser: Karate champ, strong willed and, wears many types of dresses.
* GirlyGirlWithATomboyStreak: Ran often wears girly dresses or skirts, is a SupremeChef, likes cute things, loves the fine arts, is a sucker for romance, and is an emotionally sensitive person. She's also a world-renowned karate expert and can be HotBlooded in certain situations.
* GoodIsNotSoft: Yeah, Ran's [[NiceGirl one of the kindest and compassionate people that you'll know in anime]] and [[AllLovingHero she won't hesitate to help anyone, friend or foe]]. That doesn't mean she can't [[ActionGirl dish out a deserved physical punishment]].
* HairstyleInertia: Ran's "horn" has been a part of her hairstyle since childhood.
* HeartbrokenBadass: Whenever she discusses how Shinichi's absence troubles her. Doesn't help that she cries when she does.
* HelloNurse: Men often pick her up instead of Sonoko. To the chagrin of the latter.
* HeterosexualLifePartners:
** Has been friends with Sonoko since childhood and have always been loyal best friends who can confide in one another about their problems.
** Ran later develops one with Kazuha -- They have become close friends since their second time they met and seem to regard each other as confidantes, since they are in similar romantic situations; and when Shinichi/Conan and Heiji are on cases together, Ran and Kazuha almost always spend the time together.
* HiddenDepths: Ran has a very good memory and attention to detail, having used her both to contribute to a case investigation more than once.
* HotBlooded: Thanks to her {{Tsundere}} tendencies or when her loved ones are threaten.
* HyperAwareness: Ran has shown very alert senses in darkness, able to notice an attacker with a weapon and strike to protect herself.
* IdenticalStranger:
** Ran is said to look a lot like a younger version of [[spoiler: Ai's [[CynicismCatalyst dead older sister Akemi]] ]], to the point that [[spoiler: Ai was reluctant to get close to Ran because she was still reeling from her terrible loss... but once [[AllLovingHero Ran]] saved Ai's life, [[MoralityPet she became almost desperately protective of Ran]] [[BecauseYouwereNiceToMe as a result]].]] It even gets lampshaded when [[spoiler: Ai]] once stares at Ran and pretty much sees her as [[spoiler: Akemi.]]
** During the "The Twenty Year Old Murderous Intent: The Symphony Serial Murder Case" case, two people notice Ran baring a striking physical and character resemblance to the deceased Yoshimi Samezaki; those two people are the deceased's father (Toji Samezaki) and fiance when she was alive (Minoru Ebina).
** In the ''DC vs. Lupin III'' special, with [[spoiler: Crown Princess Mira, a troubled young girl who's caught in a conspiracy after the death of her mother, Queen Sakura, and her heir Prince Gill.]]
* IKnowKarate: Either she or someone else will mention that she is a karate champion.
* IKnowYouKnowIKnow: Know Shinchi very well, as the last time Kaito disguised himself as him she knew he is fake. [[spoiler: He tried to grab her butt.]]
* ImprobableHairstyle: Ran's trademark feature is a large lock of hair many fans refer to as her "horn".
* InformedAbility: Apparently Ran is a good singer, but she has yet to actually sing.
* IronicName: The word ''ran'' in Japanese means [[IronicName "chaos/rebellion."]] This is indirect contrast to the responsible, rule-abiding Ran Mouri.
* ItWasWithYouAllAlong: Ran is constantly looking for her childhood friend [[ChildhoodFriendRomance Shinichi]], who is with her all along as a little boy named Conan Edogawa. Conan himself [[{{Lampshaded}} lampshades]] this at one point. [[LockedOutOfTheLoop Ran still doesn't realize this fact up to the present manga chapter.]]
* IWillWaitForYou: To avoid making Shinichi choose between her and his important case (really an excuse because Shinichi has turned into Conan and can't return), she has decided to wait for him to finish it, trusting his promise that he will come back despite their separation causing Ran a lot of emotional pain.
* KickChick: Most of her karate techniques she uses are kicks.
* LadyAndKnight: The Lady to Shinichi's Knight. While Ran is a fairly strong ActionGirl, there's an arc involving her as a princess in a SchoolPlay that exploits the "princess and knight" symbolism to the hilt with her and her mutual childhood love interest [[TheHero Shinichi]], who is mostly stuck in a child's body (as the titular Conan) but [[spoiler: is temporarily back to his real physical age during said arc.]] Additionally, during ''Anime/LupinIIIVsDetectiveConan'', [[http://sandman4869.tumblr.com/post/104826108824/rans-daydream-from-lupin-the-3rd-vs-detective Ran daydreams of herself as a princess]] [[http://sandman4869.tumblr.com/post/104829226459/rans-daydream-from-lupin-the-3rd-vs-detective and Shinichi as her knight]].
* LightningBruiser: Despite her slender frame, Ran has considerable raw strength for her frame, as seen from prying open powerless elevator door. She is also shown to be remarkably fast, able to quickly react to and knock away falling pipes and likewise dodge a bullet up-close while on guard. Her strikes have also shown similar speed, able to swat down a bee with a single kick.
* LivingEmotionalCrutch:
** Ran is this to Shinichi. The thought of her showing interest in other guys makes him [[CrazyJealousGuy almost childishly jealous]] and it's mostly PlayedForLaughs. At worst, whenever Ran has disappeared/been attacked/been wounded/[[spoiler: believed to be ''dead'']], Conan has either fallen into {{Heroic BSOD}}s and, at least once, has been dangerously close to crossing the DespairEventHorizon. The best evidence comes from the sixth non-canon movie, [[spoiler:Conan basically gave up all hope of getting out of the virtual game, when Ran [[HeroicSacrifice sacrificed her life]] to save him from Jack the Ripper.]] And in both canon and non-canon material, Shinichi has often referred to Ran as his "most precious person in the world".
** Ran grows to become this to Haibara. At first, Haibara avoided her because it was her [[TheQuietOne usual]] [[SugarAndIcePersonality attitude]] and Ran's strong resemblance to her dead sister. However, after spending some time together and [[spoiler:Ran saving Haibara from being killed by Vermouth]], Haibara now takes a special interest in protecting her from the [[BigBad Black Organization.]]
* TheLoad: If her martial skills are not requested, generally she doesn't contribute much to the resolution of the cases.
* LockedOutOfTheLoop: Out of everyone, Shinichi is ''most'' adamant about keeping his identity as "Conan Edogawa" and the Black Organization a secret from Ran as much as possible.
* LongDistanceRelationship: A variant with Shinichi. She thinks that he has run off to investigate some kind of case, but in truth he's Conan, aged down thanks to plot.
* LovableJock: One of the best on her karate team and is one of the sweetest characters in the series.
* LoveEpiphany: The "Shinichi Kudo's New York" case reveals that Ran first realized her love Shinichi was after they both saved a serial killer at the time (who was Vermouth) in disguised. When the disguised killed asked why they would do something like that, Shinichi responds that while he can't understand why people kill, there doesn't have to be a reason to save a life. Thanks to Shinichi's answer Ran realizes that the earlier murder wasn't her fault... and when she finally wakes up out of the dreams, she remembers how that night was the night she realized her feelings for Shinichi and how important he is to her.
* LovesMyAlterEgo: {{Inverted|Trope}}. She loves Shinichi (the original person), but she also deeply cares for Conan (new identity).
* MeaningfulName: Ran likes to rush wherever she goes, believing her name to be like the "Run" word from English. She even said to Shinichi that, "My name is Ran! I was born to run!"
* MindlinkMates: With Shinichi -- they appear to share a close empathic link due to their strong feelings for each other, making them almost impossibly aware of when the other is in extreme danger, and often able to sense the other's worried thoughts.
* MoralityPet:
** Along with Shinichi, [[spoiler:she is this to [[FemmeFatale Vermouth]] from the Black Organization. After Ran saved Vermouth's life in New York City, Vermouth nicknames Ran "Angel". Earlier, Vermouth, as her Sharon Vineyard role, complained that her life was a series of misfortunes and, "No angel has smiled upon me, not even once." Even though Vermouth in disguise prepared to kill Ran later, Ran stopped Vermouth from taking a fatal fall. Vermouth was touched by this act of kindness. Much later in the story when Ran shielded Haibara from gunfire with her body, Vermouth refused to shoot Ran or allow her to be shot, instead firing around her in an attempt to frighten Ran into releasing Haibara. Vermouth has stated that Ran and Shinichi are the only two treasures she has in the world.]]
** {{Downplayed|Trope}} in regards to [[InsufferableGenius Shinichi.]] He isn't a a psychopath or even a straight up jerk, but one reason for his lack of close friends was because his arrogant personality was a negative turn-off to many of his classmates and even teachers, making it hard to befriend him. Ran was the only exception.
** Eventually becomes one to [[TheCynic Haibara]] after she [[spoiler:saved the latter from being killed Vermouth. Since then, Haibara has taken a special interest in protecting Ran from Black Organization.]]
* MusclesAreMeaningless: She has a curvy, normal build for a teenage girl. She can also hurl men who are twice her height and/or triple her weight and punch small craters in brick walls with a cheerful smile on her face.
* NervesOfSteel: She has remained bold, steady, confident and calm in many situations that would usually cause others to remain frozen in fear, such as being threatened by a gun or surrounded by flames.
* NiceGirl: Ran's greatest personality trait is that she genuinely cares for those she loves. She is also patient, kind, and nurturing.
* NoSenseOfDirection: She easily gets herself lost.
* OneWomanArmy: During one case, Ran was able to successfully take out 50-60 gang members...who had ''katanas''.
* OnlyFriend: Before turning into Conan, Shinichi's primary friend was Ran.
* PassionateSportsGirl: The source of her {{Action Girl}}ness. And she takes her karate ''very'' seriously.
* PluckyGirl: Tearful and sensitive as she can be, it's not easy to make her give up.
* {{Protectorate}}: Shinichi/Conan will always make sure that no harm comes to Ran.
* PunnyName: Ran is nicknamed "Ranmaru" by her rival and good friend, [[Characters/DetectiveConanOtherRecurringCharacters Hina Wada]] based on "Mori Ranmaru"--a famous samurai affiliated with UsefulNotes/OdaNobunaga.
* RapunzelHair: Her hair reaches down her waist line.
* RedOniBlueOni: The calmer, sensitive Blue Oni to Kazuha's HotBlooded, temperamental Red Oni.
* RelationshipUpgrade: As of file 1006, [[spoiler:she and Shinichi are officially a couple.]]
* ReplacementGoldfish: To Ai, since Ran greatly resembles her dead sister.
* RescueRomance: With Shinichi -- they've mutually helped and rescued each other (even if Shinichi is in his Conan form almost all the time) several times - often a ''great'' risk to themselves. Lampshaded once when Ran's drugged and almost forcibly drowned at some point, then Conan rushes in to help her; thanks to the drug and lack of oxygen she sees Conan as Shinichi, and before passing out she smiles and says "Don't worry, I'm okay... Shinichi came to save me..."
* SecretSecretKeeper: [[spoiler: An incident involving blood transfusions implies she might know that Conan is Shinichi]].
* ShipperOnDeck:
** Ran wishes for her parents to get back together.
** She supports Heiji and Kazuha becoming a couple.
** She ships Sonoko and Makoto.
** Ran seems to think that Conan and Ai would be cute together.
* SingleTargetSexuality: Even though it took her slightly longer than Shinichi, Ran has only ever had eyes for him.
* SingleWomanSeeksGoodMan: Some people have wondered [[WhatDoesSheSeeInHim why Ran would like a guy like Shinichi]]... Well, in a private discussion with Conan (aka Shinichi himself), Ran stated that while [[InsufferableGenius he may have]] [[JerkWithAHeartOfGold an unpleasant]] [[IceKing personality]], he's also [[UndyingLoyalty brave and someone you can rely on in a pinch.]] In fact, [[LoveEpiphany Ran first realized she was in love with him]] when he helped save a SerialKiller from falling to his death. When asked by the said killer why he [Shinichi] would even consider doing such an act, Shinichi responded with: [[ThouShaltNotKill "People kill each other and I don't understand,]] [[AllLovingHero but for saving a life, is a logical reason necessary?"]]
-->'''Ran:''' ''(to Conan)'' Ever since he [Shinichi] was little he was a jerk, always full of himself, and a mystery otaku. But whenever you need him, he's dependable and brave and cool. ''I really like Shinichi!''
* StarCrossedLovers: With Shinichi. While their feelings [[BelligerentSexualTension have been kinda wavering]] for quite the while, as time passes they have grown stronger - but Shinichi is trapped in the body of a little boy (the titular Conan) and cannot openly tell Ran who he is, lest she and his friends will be targeted by the same evil organization that shrunk him. In the meantime poor Ran waits for Shinichi's return...
* StrongFamilyResemblance: Ran gets her physical looks from her mother, with the only thing she got from her father was her dark-brown hair.
* StrongGirlSmartGuy: With Shinichi. While Ran is karate champion whose strength borders on CharlesAtlasSuperpower, he's a TeenGenius detective who can solve supposed impossible crimes.
* SupremeChef: Ran is a Karate expert and has been repeatedly told she's a great cook.
* TenderTears: [[LampshadeHanging Lampshaded]] by [[spoiler: Shuuichi Akai]].
-->[[spoiler:'''Akai''']]: You are crying again... You are always crying.
* ThouShaltNotKill: Best summed with this quote that was one of her many [[CrowningMomentOfAwesome Crowning Moments Of Awesome]]:
-->"Courage is a word of justice. It means the quality of mind that enables one to face apprehension with confidence and resolution. It is not right to use it as an excuse to kill someone."
* TomboyAndGirlyGirl: One may ''think'' she's the tomboy to Sonoko's girly girl, but Ran is [[PlayingWithATrope more complex than that.]] Sonoko is less physically active and more boy-crazy/fashionista than Ran, but is also more outspoken and straightforward than her (unless Ran's in tsuntsun more, yeah). In fact, their friendship started when ''Sonoko'' protected Ran when they were children!
* {{Tsundere}}: She's default Type B or deredere (gentler). Just don't piss her off.
* TwiceShy: With Shinichi. Even after he became aware of her feelings for him as Conan, when he returns to his original body, he gets too scared to properly confess...until the London arc. And after the said arc, Ran has yet to give him an answer.
* UndyingLoyalty: She'll ''never'' turn her back on her loved ones.
* ViolentlyProtectiveGirlfriend: {{Subverted|Trope}}. She and Shinichi are each other's love interest, but aren't technically together, since Shinichi has turned into Conan. Everytime Ran gets protective of him, it's more like BigSisterInstinct and/or MamaBear.
* WackyParentSeriousChild: The CuteBruiser Serious Child to Kogoro's ManChild Wacky Parent.
* WeaksauceWeakness: Ran gets easily sick when reading in a car.
* WhatDoesSheSeeInHim: Others, especially Sonoko, can't understand why Ran would like mystery {{otaku}} like Shinichi. Ran answers this question when talking to "Conan" that despite his flaws, Shinichi has many other admirable qualities she loves, such as his bravery and reliability. Also, in a private conversation with Kazuha, Ran admits that despite calling Shinichi a "mystery geek" to his face, she actually thinks he looks cool when he solves a case.
* WhatWouldXDo: Whenever Ran is faced with a particularly difficult situation she would often question what would Shinichi do if he was in the same predicament.
* WhyDidItHaveToBeSnakes: She has a fear of ghosts. Not because they're supernatural per se, though, but because they're intangible--meaning her martial arts will have absolutely no effect.
* WiseBeyondHerYears: Ran is very self-sufficient for her age, since her father is often drunk, slovenly, and fiscally irresponsible. She handles many of the Mouri household's financial affairs and all the cooking and housework.
* YouRemindMeOfX: Both Shuichi and Haibara have noted how Ran is ''very'' similar to Akemi in both appearance and personality.
* ZettaiRyouiki: Sports the look from time to time. It's quite noticeable [[http://www.youtube.com/watch?v=7Yl9LOFRWGQ in the first OP]], where she sports a Type A... if she added TwinTails, her Type B {{Tsundere}} traits would give her a Grade S.

[[folder:Kogoro Mouri]]
[[quoteright:149:http://static.tvtropes.org/pmwiki/pub/images/1434277.jpg]]
->''Voiced by Creator/AkiraKamiya / Creator/RikiyaKoyama (JP)/ R. Bruce Elliot (EN)''; Juan Zadala, Carlos Carrillo and Roberto Alexander (first Latin American Spanish dub); Víctor Covarrubias (movies 1 and 2 and 18 onwards plus first Anime/LupintheThird crossover, Latin American Spanish dub) Sergio Schmied (third Latin American Spanish dub), Luis Espinosa (first European Spanish dub and second part of the second one), Ángel Amorós (second European Spanish dub, second part and movies), Takanori Jinnai (Live-Action Drama Actor)

Ran's father and estranged husband to Eri Kisaki.

He runs a private detective agency, but is mostly out of the job due to his constant drinking, gambling, womanizing and being described as a joke regarding the cases he actually takes. That all changes after Shinichi shrinks and needs a scrapegoat to solve the cases for him; bringing to life the ''Sleeping Kogoro'', which Kogoro later becomes famous for and allows him to take more noteworthy cases. Though, he's still heavy on the drinking, gambling and womanizing.

He also happens to be a big fan of the idol singer, Yoko Okino.

[[ThemeNaming Mandatory naming note]]: "Kogoro" came from [[http://en.wikipedia.org/wiki/Kogoro_Akechi Kogoro Akechi]], the GreatDetective in Rampo Edogawa's novels.

DubNameChange: Richard Moore.
----
* ActionDad: A master in judo and the father of the deuteragonist, Ran.
* AdultsAreUseless: Well, considering that Shinichi/Conan and other teen detectives are in general more competent and active than ''everyone''. To be fair, he often comes to conclusions a real life detective would think, given the extremely elaborate nature of these cases. His FatalFlaw is the fact that he's impatient and rather shortsighted - he wants to finish every case as fast as possible. When it comes to apprehending known criminals, he's shown to be ''far'' more competent.
* AesopAmnesia: Despite seeing how Conan's hints help in solving cases and how Heiji is actually a competent detective, Kogoro ''still'' thinks both of them are nuisances to an investigation.
* AlcoholicParent: Frequently gets intoxicated and it's played for both drama ''and'' comedy. [[PlayedForDrama In the "Drama" part]] he does have a good perception in solving cases at times, but most of the time, he just wastes time drinking (to the point [[ChildrenRaiseYou Ran is the one who keeps the house in order]] and, in at least one case, he's seen [[DrowningMySorrows straight-up drinking his sorrows away]] because he can't handle [[spoiler: that a kind girl he used to know [[BrokenPedestal is the most likely culprit]].]] In the [[PlayedForLaughs "comedy" part]], he's seen dancing or sleeping drunkenly with his tie around his forehead and is more of a ButtMonkey than usual.
* AmazinglyEmbarrassingParents: To Ran, and to Conan in a ParentalSubstitute way. He's a clumsy, womanizing father who's main vices include alcohol and gambling. She once chewed him out for taking Conan to a {{mahjong}} parlor behind her back.
* AwLookTheyReallyDoLoveEachOther: Has many such moments with his estranged wife, Eri. Pretty much whenever they meet, they spend the entire time nagging each other, but these episodes usually end with a clear indicator that they still care for each other.
* BadassInANiceSuit: Officially starts to sport this look after his fame as a detective skyrocketed.
* BadassMoustache: His mustache is well-trimmed.
* BadassTeacher: He was able to teach Judo to Ran and Eri.
* BelligerentSexualTension: With Eri. They are a ''married couple'' and argue to hide the fact that they want to live with one another again.
* BeneathTheMask: It's shown only a few times, but it ''shows''. While on the surface he looks like a womanizing, drinking jerk, he's actually a SadClown who feels like he's a horrible father to Ran and he deeply regrets being away from Eri for so long.
* BerserkButton: Anyone double-crossing, tricking, lying, or downright betraying him; finding out that [[spoiler: one of his TrueCompanions from college was not only a murderer, but that they had killed ''another member of his group of friends'']] had Kogoro completely '''fuming''' like few times it has happened in the whole manga.
* BewareTheSillyOnes: Yeah, he's a [[ChivalrousPervert shameless flirt]], [[BumblingDad embarrassing father]], and too many other flaws to count. He's also a master of judo and doesn't take either betrayals/lies and/or threats against his loved ones well.
* BigEgoHiddenDepths: Beneath Kogoro's enormous and inflated ego is a man who doubts himself as a father and is lonely from the absence of his wife.
* BrilliantButLazy: To a certain degree. He's actually quite capable as a detective, but he usually just wants the case to be over and done with, so he assumes his first theory is right and refuses to believe otherwise until proven wrong. His main problem is that he usually does not bother to closely examine all the evidence, so he never finds those crucial details pointing to the culprit. Even when Conan hands him these details, he's too lazy to think things through completely or examine every possible solution before making an accusation.
* BumblingDad: To Ran and Conan. Basically a loser, but his care towards his daughter Ran is utterly remarkable.
* ButtMonkey: If something funny, humiliating or painful is going to happen, the first-rate candidate is Kogoro.
* CannotSpitItOut: Even though he desperately misses having Eri home, he'll never admit it. The ''one time'' he did ask her to come back home, she pretended she was listening to a tape, citing her reasons "he wasn't ready yet".
* CantActPervertedTowardALoveInterest: Kogoro will flirt with every cute girl and beauty except Eri, or anyone who looks like her, much to Sonoko's wonder. He also sometimes becomes cooler and more perceptive when he meets someone that reminds him of her.
* CantLiveWithThemCantLiveWithoutThem: With his estranged wife, Eri. At one point, Kogoro even outright states that he cannot bear being separated from Eri and asks her to come back, but she pretends she didn't hear him because she's not ready yet.
* CasanovaWannabe: Has a habit of hitting on pretty women with no luck. However, this only goes as far as flirting and it's heavily implied he does this as a self-defense mechanism to protect him and Eri from anymore emotional pain.
* CharacterTics: {{Subverted|Trope}}. When he goes into "Sleeping Kogoro" mode he makes a weird noise and looks down to the ground before beginning his deduction. In reality, it has less to do with being an inborn habit but Conan using a tranquilizer on him.
* ChickMagnet: His rise as a famous detective has many women fawning over him.
* ChildhoodFriendRomance: With Eri. They have known each other since elementary school and are now married, if estranged.
* CluelessDetective: He's a tad too tunnel-visioned, so he usually jumps to the most obvious deduction, frequently the one the culprit wanted the investigators to believe. Because he's got a severe case of tunnel vision, he never bothers to look for further evidence or question his conclusions after that, which is why he almost never finds the correct solution.
* CrazyJealousGuy: An old high school friend even stated that Kogoro would glare at any guy who looked at Eri.
* CrouchingMoronHiddenBadass: Something (usually a personal matter) might cause Kogoro to actually focus all his attention on a case, revealing him to actually be a very capable detective on his own. This is most evident when it comes to apprehending known criminals, or if someone presses his BerserkButton...
* TheCynic: In cases, he usually goes with the most straightforward way the criminal committed the crime, hardly accepting any other theories.
* DefectiveDetective: He's horribly bad with money, is often seen drinking or gambling and can't fix his relationships with his estranged wife. Before Conan helped him gain some success as a detective, he was completely down on his luck, but even now he clearly has issues. Alternately PlayedForLaughs or [[PlayedForDrama Drama]].
* DrinkOrder: Beer is his favorite alcoholic beverage, and while he's not a commoner he is of middle-class.
* DumbMuscle: {{Downplayed|Trope}}. The ''one'' thing Kogoro can do right is his judo. But even though he can be quite the incompetent detective, it's more out of impatience than actual stupidity since he does so flashes of being on the same deduction level as Shinichi when there's a personal case to him in which he applies himself.
* EveryoneHasStandards:
** In the non-canon movie, ''The Time-Bombed Skyscraper'', Kogoro is ''pissed'' that Shinichi left Conan alone with a phone (connected to the criminal), when the said kid could've been in grave danger.
** He also thought Commissioner Hattori hitting his son in a case was going too far and ''really'' objected to [[spoiler:how he manipulated said son into getting the criminals to reveal themselves.]]
* ExpositoryHairstyleChange: In middle school, Kogoro's hair was spikier and unkempt. However, upon high school and the current storyline, his hair is now combed down.
* FakeUltimateHero: Many episodes features this, as Conan's deductions are revealed in the voice of the unconscious Kogoro Mouri, building the man's reputation as a detective (despite the fact that Mouri is a mediocre detective at best).
* FamedInStory: By the end of the first season, he has gotten a reputation as a {{meitantei}} (on the strength of Conan's behind-the-scenes work) and is often recognized by face or name by those around him. Frequently, when Kogoro's name and/or vocation enters conversation, it will provoke reactions of shock in the (not-yet-known-to-be-a) murderer (and/or others with something to hide). Although Kogoro almost never notices, Conan usually does--and this is often his first clue that something is amiss.
* {{Fanboy}}: Of IdolSinger Yoko Okino.
* FatalFlaw: A lot of murderers could've gotten away with their crime(s) because of Mouri's frequency to want to close the case as fast as he could.
* TheGamblingAddict: He often makes bets on horse races or plays pachinko. He ends up losing most of the time.
* GeniusDitz: When he applies himself, Kogoro can solve a case.
* GenreBlind: He keeps lecturing and often outright disciplines Conan for putting his nose into important cases on his own, even though his help is what mostly always helps Kogoro and police notice the most important details and clues.
* GreatDetective: {{Zigzagged|Trope}}. Ar first it seems that Kogoro is an inept detective (and that is for the most part), often trying to quickly solve a case with the fastest resolution (i.e., suicide), leaving Conan to solve the case and (usually) use Kogoro as a dummy. Therefore, his fame as the "Great Detective Sleeping Kogoro" is mostly thanks to Conan. However, in a few cases that are personal to him, he's show a surprising sense of deduction that is may be on par with Shinichi's.
* {{Greed}}: PlayedForLaughs. People have often gotten Kogoro to do something with the promise of money.
* HeartbrokenBadass: Despite denying it, Eri leaving him and ''still'' not coming back, deeply hurts him.
* HiddenDepths:
** Kogoro often demonstrates he has a better sense of interpersonal relationships than Shinichi does.
** Despite his frequent moronic analyses, Kogoro is actually pretty smart when he applies himself.
** He wrote a screenplay so capable, Yoko Okino agreed to star in it.
* HighSchoolSweethearts: With Eri -- They have a ChildhoodFriendRomance which included going to the same high school together before marrying at the age of 20.
* IdiotHero: ''Very close'', but it's more of him being impatient and cynical.
* JerkWithAHeartOfGold: Womanizer? Check. Alcoholic? Check. Giant ego? Double check. Loves his daughter and wife (even if he's estranged with the latter)? Check. Cares for Conan just as much as he would if he were his son? Check. Has a strong sense of justice? You bet he does.
* LovableSexManiac: Kogoro's lecherous nature often leaves him open to easy manipulation by Ran or Conan (and occasionally clients, murderers, or murder victims), and also usually torpedoes every one of Ran's attempts to get him and Eri to reconcile. He never actually seems to take it any farther than ogling or, at most, platonic dating with the objects of his temporary affection. (He also maintains a persistent crush on idol Okino Yoko.) Given that Kogoro's lechery seems more talk than action, and he was presumably monogamous with Eri until they parted after [[spoiler:Kogoro had to shoot Eri in the leg to save her life when she was caught in a HostageSituation]] in a flashback in ''The Fourteeth Target'', this may just be his way of distancing himself from Eri to keep either one of them from being hurt again.
* ManChild: Sometimes, his daughter Ran acts more like his wife or mom.
* MrViceGuy: He has a ''lot'' of vices and frequently indulges them, but he's still fundamentally a decent guy. Oddly enough, Kogoro's original voice actor had plenty of experience playing a LovableSexManiac, as he was also the voice actor for ''Manga/CityHunter'' Ryo Saeba. (In another character's thought balloon in one of the [=OAVs=], Kogoro even used Saeba's CatchPhrase "mokkori".)
* OOCIsSeriousBusiness: Anytime Kogoro ''stops'' acting like a comedic, womanizing clown is when a case has gotten ''serious''.
* OverprotectiveDad: Don't you ''ever'' dare to look at his beautiful daughter Ran in any way he doesn't like.
* PapaWolf: Do ''not'' threaten Ran or Conan when he's around, as this is one of the FEW ways to make him act 100% competent. Don't say we didn't warn you, thieves.
* ParentalSubstitute: To Conan. While Kogoro seems to be uncaring towards his ward, he does show a PapaWolf side should Conan be in danger.
* ParentsAsPeople: While he does care for Ran, Kogoro is still an immature man with issues he has yet to work out.
* PrivateDetective: Most of the detective characters in this series are [[AmateurSleuth Amateur Sleuths]], Kogoro is one of the few who makes his living as a detective. Before Conan moved in, he wasn't exactly successful at it, however.
* PromotedFanboy: InUniverse. Upon solving a case for her and becoming increasingly famous as a detective, he frequently received merchandise and invitations to various events from Yoko. He even got to make a guest appearance in her cooking show and would have starred in another show hosted by her if it hadn't [[ExecutiveMeddling got the axe]].
* RealMenWearPink: He's a HUGE fan of [[IdolSinger Yoko Okino.]]
* RedBaron: "Sleeping Kogoro." This of course refers to the effect of Conan's sedation dart, but is also a ShoutOut to Katsura Kogoro (aka [[http://en.wikipedia.org/wiki/Kido_Takayoshi Kido Takayoshi]]), who was also known as the "Fleeing Kogoro."
* SadClown: It's heavily implied that Kogoro's constant flirting (which is {{played for laughs}}) with other women is just a way to deal with the pain of not being with Eri.
* SharpDressedMan: While he likes to slouch around unkempt in his apartment when alone, he can change into an exquisite suit within seconds when a client or a beautiful woman shows up at his doorstep. As his fame as a detective increases, he adopts this appearance permanently.
* ShippingTorpedo: {{Downplayed|Trope}}. Kogoro doesn't actively try to wane Ran's love for Shinichi, but he has often advised her to give up on him.
* SingleTargetSexuality: Don't let his flirting with other women fool you. That's only to mask his despair from being separated from his beloved wife, Eri.
* SmallNameBigEgo: Though, in his defense, Conan lets him take the credit for solving the cases.
* SmallRoleBigImpact: Kogoro indirectly lead to Shinichi and Ran first meeting each other, by [[spoiler: accidentally breaking Ran's cherry blossom-shaped daycare tag. She tried to make one made of paper and Shinichi asked her for one for himself.]]
* SmartBall: Depending on your point of view, Kogoro could also be said to catch this ball a few times over the course of the series whenever he actually manages to get a deduction right. Well-seen in the end of the Scuba Driving episode, and in the episode where he fell asleep on the train. (He actually had it solved - the only reason Conan had to step in was because he fell unconscious.) His most shining moment, however comes in "The Unseen Suspect", where he flat-out gets something right that Conan got ''wrong'' (granted, Conan smuggled in a few hints about the actual murder method, but he ''never'' foresaw that two of the suspects were [[spoiler:father and daughter]]. Kogoro did).
* SmokingIsCool: Kogoro is a heavy smoker, and is usually seen with a cigarette in his mouth; he even tries to invoke this image a few times when showing off. And while he may be a buffoon at times, Kogoro is capable of being a threat when pushed and has often showed to have the deductive skills like the protagonist when he applies himself.
* ThouShaltNotKill: Said word for word when he delivers an awesome TheReasonYouSuckSpeech to a college friend who killed another college friend.
-->"You're right, old pal. I'll never understand no matter the reason what drives someone to murder. And I don't think I want to."
* TranquilFury: Kogoro does have a serious side which only emerges when the case has personal importance to him, such as when Eri and Ran are involved. When this happens, Kogoro's entire personality and demeanor changes and he begins acting professionally, demonstrating improved deductive skills and cunning.
* {{Tritagonist}}: Of the entire series.
* UnsympatheticComedyProtagonist: In the early seasons/volumes he regularly punched, kicked, and harshly berated Conan, who remember, despite actually being 17, is in the body of a 7 year old. Thankfully, this gag has largely disappeared in recent years.
* WackyParentSeriousChild: The ManChild Wacky Parent to Ran's CuteBruiser Serious Child.
* WhyDidItHaveToBeSnakes: In the movies, Kogoro suffers from a mild acrophobia (fear of heights) and is quite uncomfortable in high settings where he has the chance to see how high up he is. He does not have this fear in the manga.
* WouldHurtAChild: PlayedForLaughs. In the earlier chapters/episodes, he would yell at, throw, and even punch Conan for simply opening his mouth. He even went as far as placing his fist on Conan's head and saying "Killing move... DRILL PUNCH!" and delivering the noogie from hell.

[[folder:Ai Haibara/Shiho Miyano/Sherry]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/shiho_ai87654.png]]
->''Voiced by Music/MegumiHayashibara (JP) / Creator/BrinaPalencia (EN)'', Carmen Amadori and María Luisa Benech (third Latin American Spanish dub), Cecilia Gómez (movie 18 onwards, Latin American Spanish dub), Silvia Sarmentera (second European Spanish dub and movies), Kyoka Shibata (Live-Action Drama Actress as Ai Haibara), Yu Kashii (Live-Action Drama Actress as Shiho Miyano)

A young girl whose true identity is Shiho Miyano, aka "Sherry" of the Black Organisation. She is the genius chemist who created the APTX-4869 drug that turned Shinichi into a six-year old boy. After she is imprisoned by the Black Organisation for being related to the traitor, Akemi Miyano, Shiho attempted suicide with a dose of APTX-4869 but was instead de-aged as well. Using her newly-shrunken body to escape and go into hiding as "Ai Haibara", Shiho is taken in by Shinichi's next door neighbour and uses her condition to live out the innocent childhood she never had. She joins the Detective Boys as a way to make amends for her past crimes, and works on an APTX-4869 antidote for Shinichi.

[[ThemeNaming Mandatory naming note]]: ''Haibara'' came from [[http://en.wikipedia.org/wiki/Cordelia_Gray Cordelia Gray]]; Haibara literally meant ''Gray''field. ''Ai'' came from flipping the ''V'' in [[http://en.wikipedia.org/wiki/V._I._Warshawski V.I. Warshawski]]-- the kanji usually associated with the sound "Ai" means love, but she took the [[AlternateCharacterReading alternative]] for "[[MeaningfulName sorrow]]."

DubNameChange: Anita Hailey (Creator/VizMedia); Vi Graythorn (Creator/FUNimation)
----
* ActingYourIntellectualAge: Since Haibara doesn't put any effort in deliberately acting like a child, she appears to be this to in-universe bystanders.
* ActionGirl: Not nearly to the extent of Ran or Masumi, but when the occasion calls for her to do something cool, she doesn't shy away from it. Even in her shrunken state, she's been shown to trip and drop men who weigh five times as much as her, and [[spoiler: when forced to revert to her true age to save the Shounen Tanteidan from a burning cabin, she effortlessly destroyed the door with an axe.]]
* AdorablyPrecociousChild: Since she's really 18-years-old, Haibara often appears quite mature in front of people.
* AllOfTheOtherReindeer: Got her education in America, where she was picked on for her Japanese features.
* TheAtoner: Ai now works to find the antidote for the poisonous drug she created and to take down the Black Organization.
* BecauseYouWereNiceToMe:
** A combination of Shinichi/Conan's DeclarationOfProtection, the natural friendliness of the Detective Boys, and Professor Agasa's fatherly nature allowed Ai to break out of her shell little by little.
** [[spoiler:Ran protecting her from being killed by Vermouth had Ai think of Ran as a LivingEmotionalCrutch and MoralityPet.]]
* BetterToDieThanBeKilled: She attempted this when she was locked up for betraying TheSyndicate, rather than facing execution. She took a poisonous drug she created, but instead of dying she suffered its [[MillionToOneChance ''other'' effect]], which [[FountainOfYouth shrank her to the size of a six-year old little girl]]. Because of that, she was able to escape and... you know the idea.
* BigSisterInstinct: She is quite protective over the Detective Boys, especially Ayumi.
* BigSisterWorship: Haibara truly loved her sister. And was devastated by her death.
* BreakoutCharacter: Introduced more later in the manga, Ai has become one of most important characters in the series with more screentime. She is also very loved by fans thanks to her personality and the ShipTease with Conan.
* BrokenAce: She was one of the top scientists in her field...too bad it was with the [[BigBad Black Organization]]. Besides that, Haibara was [[AllOfTheOtherReindeer bullied while studying in America]], [[DarkAndTroubledPast raised in the Black Organization]], only heard bad things about [[MadScientist both]] [[IceQueen parents]] and hardly saw her [[LivingEmotionalCrutch beloved sister.]]
* BrokenBird: Her choice of a pseudonym underscores this. As said before, the kanji for "Ai" doesn't mean "love", but "sorrow".
* ButNotTooForeign: Ai's mother Elena was British.
* CharacterDevelopment: Over the course of the series, Haibara loses her suicidal thoughts and stops running away from the B.O.
* TheChessmaster: The stint in Volume 26 of the manga established that.
* ChekhovsGunman: Shiho's silhouette appeared in chapter 16, when Akemi mentioned her younger sister during her last conversation with Gin. Ai makes then a proper appearance exactly 160 chapters later.
* ChildProdigy: {{Implied}}. When Shuuichi Akai joined the Organization as an undercover agent, Ai was just thirteen years old. At that time, she was already important enough to the Organization as a scientist that getting close to her gave Akai the connections and influence he needed to successfully infiltrate their inner ranks.
* ChronicHeroSyndrome: Denies having this and claims that she, unlike Conan, is not interested in such abstract concepts as 'justice'. Gin, however, predicts that once she has heard about a murder the Organization has planned, she WILL show up to try and stop it because that's the kind of person she is. He's right.
* CowerPower: When Haibara is frightened, such as when she senses someone from the Organization close by, she will grab onto and hide behind someone. Most often this is Conan or Professor Agasa. The "Red, White, Yellow" case featured her grabbing Mitsuhiko so hard she accidentally hurt him and the Mystery Train had her clinging tightly to Ran.
* CreepyChild: Conan is much better at coming across as a normal kid than she is, which is saying something. In her first appearance, she terrified a gang leader by picking up the woman's gun and shooting her at point blank range, intentionally missing only by a short margin.
* CutenessProximity: Animals bring out the "sugar" of her SugarAndIcePersonality.
* TheCynic: Being raised in the dark and mysterious Black Organization really took a toll on Haibara's sense of hope, justice, and innocence.
* DamselInDistress: Occasionally, for example when Conan has to save her from Pisco, Gin and Vodka.
* DarkAndTroubledPast: Inevitable, having been raised by the Organization.
* DeathSeeker: Believing that it's only a matter of time for TheSyndicate to find her and kill everyone she's associated with, she willingly remains in a bus that has a bomb about to go off because she doesn't want to put those around her in danger. Conan pulls her out in the nick of time. In a later volume, she surrenders herself to [[spoiler:Vermouth]] in exchange for her promise that no one else will be harmed, but is rescued again.
* DefrostingIceQueen: Cynical by nature and experience, Haibara preferred to keep everyone around her at arm's length at first and was extremely reluctant to show her face at public events. It takes time for Agasa, Ran and the Detective Boys to get through to her, but she gradually becomes friendlier towards them and more willing to take measures to keep them safe from harm.
* DeliberatelyCuteChild: Averted. Unlike Conan, Haibara never bothers with this. The one time she did, in one of the movies, it freaked Conan out something fierce.
* EatingLunchAlone: She claimed she was that when she was in school. [[TeenGenius Not]] [[IntelligenceEqualsIsolation surprising]].
* {{Fangirl}}:
** In fashion, she likes the products from Prada and Fusae Campbell.
** Haibara is a big fan of Big Osaka in general and of the player Ryusuke Higo in particular.
* TheFashionista: A milder example. When not at work, she nearly always read fashion magazines. She also sometimes demands expensive purses or other fashion items in return for favors.
* FindTheCure: After swallowing the APTX pill, getting shrunk, escaping the syndicate, and meeting fellow APTX victim, Conan, Haibara has made it priority to find a cure to reverse back to their true ages.
* FountainOfYouth: The APTX-4869 drug regressed Shiho's body by around ten years, causing the TeenGenius to live in a first grader's body, who would be known as "Ai Haibara". On the other hand, APTX-4869 is [[MillionToOneChance employed as a poison and is generally successful.]]
* FriendToAllLivingThings: Haibara is a huge animal lover.
* FriendlessBackground: Her sister was the only person close to her before she was shrunk and met Agasa, Conan and the Detective Boys. One of the reasons why she's much less eager to change back than Conan.
* GuileHeroine: {{Justified}}. She was raised in an organization that specializes in manipulation. Thankfully, she uses it for good intentions.
* HeelFaceTurn: Before she appears, no less. Though it's questionable how much of a bad guy she was in the first place, as she might not have had much choice in working for the Organization, seeing how both her parents were members and the Organization was not willing to let someone with her potential slip away.
* HiddenEyes: When we see her adult form in flashbacks, her eyes are usually covered by BlindingBangs or otherwise hidden. [[spoiler: Not when she temporarily returns to her old body in the present story, though.]]
* HopelessSuitor: It's strongly implied she has romantic feelings for Shinichi/Conan, but given how open he is with his love for and ''only'' for Ran, she most likely keeps her feelings to herself.
* HotScientist: In her older form. As a child, her classmates find her very cute, but of course have no idea that she's a scientist.
* IJustWantToBeNormal: One reason why she is in no hurry to get back her old body and become "Shiho Miyano" again is because she has a happier, more normal life as "Ai Haibara".
* ImprobableAge: {{Reconstruct}}ed. She led the Organization's poison lab before she was shrunk-- that was when she was ''18''. She does not enjoy the IntelligenceEqualsIsolation part of her past life, in addition to being separated from Akemi. She took this chance to re-live the childhood that she deprived when she was young and feels like that-- this is why she's not in an urge to take the antidote herself.
* IntelligenceEqualsIsolation: One of the reason she's not willing to change back.
* JerkassFacade: Justifies many of her more altruistic acts with pragmatic, self-serving motives.
* JerkWithAHeartOfGold: Haibara has a jaded demeanor, standoffish-like nature, and dry sarcasm. Despite all that, she can be kind and caring, though usually more to animals than people.
* LadyAndKnight: A platonic version with [[spoiler:Shuichi Akai]] with her as the Lady. When the already adult [[spoiler:Akai]] gave a DeclarationOfProtection to her [[spoiler: while masquerading as Subaru Okiya]], he explicitly compared her to a princess and himself to a knight that would protect her. Subverted in that there are no romantic undertones because [[spoiler: not only Ai is much younger than Akai ''and'' is OlderThanTheyLook thanks to a FountainOfYouth, but she is the sister of his [[TheLostLenore dead girlfriend Akemi]], who is implied to have asked him to protect Ai before being murdered.]]
* LastNameBasis: She was this at school, which unsettles Ayumi. Ayumi later gets permission to call her by her first name, but not the other Detective Boys.
* LittleMissSnarker: She mainly snarks Conan. On occasion she's done this to Agasa as well, at least where his eating habits are concerned.
* LockedOutOfTheLoop: Conan regularly keeps her clear of his investigations into the Black Organization when he can help it. This has backfired, such as when Haibara's sudden appearance during the first encounter with Vermouth derailed Conan's plan. It worked more in their favor in the Mystery Train arc, where it made sure Haibara didn't take any actions that would rouse enemy suspicion before it was time to bring her into the plan.
* LonerTurnedFriend: The Detective Boys' friendship eventually turns her into this. When she was first introduced, she would often stay off to the side of whatever activity the Detective Boys were doing while later arcs, such as the Sweet and Cold Delivery Service arc, open with her playing soccer with them, and even mentally CallingYourAttacks as she's about to do one of Higo's moves.
* MartyrWithoutACause: In contrast to [[ChronicHeroSyndrome Conan]], who is quick to ''risk'' his life to protect others from danger, Haibara is quick to ''sacrifice'' it. Early in her involvement she intended to stay aboard a bus rigged to explode, viewing herself as a danger to her new friends. CharacterDevelopment gets her past much of this, but it still forms enough of her personality that both Vermouth and Conan count on it aboard the Mystery Train to predict her behavior. They correctly deduce that she would find some place private to take a temporary antidote so that when (not if) she died it would not be in her child form and prevent the Detective Boys from kicking up a fuss that might inadvertently catch the Organization's eye.
* MasterOfTheMixedMessage: As it stands, it's a mystery whether Haibara has romantic feelings for Shinichi/Conan or not. She first tells him something that can be seen as romantic but immediately declares she was joking. Then, there's her apparent jealousy of Ran (Shinichi/Conan's only LoveInterest), but that could also be seen as her not wanting to be close to someone who strongly resembled her dead sister and her usual coldness. However, it's up in the air at this point.
* TheMindIsAPlaythingOfTheBody: Even more averted than Conan, as the drug only regressed her physically and she makes no attempt to act the DeliberatelyCuteChild like Conan does.
* MixedAncestry: Ai/Shiho is half-English (mother's side) and half-Japanese (father's side).
* NewTransferStudent: How she made her official introduction as "the first transfer student since Conan arrived".
* NonActionSnarker: In a series where most women are at least adept at some form of martial arts, she stands out as having very little means of self-defense. She is a pretty crack shot with guns, especially pistols, but she just doesn't get many opportunities to use them.
* NotSoAboveItAll: Usually either serious or snarky, but she does have the odd moment of sillyness. Soccer player Ryosuke Higo in particular brings this out in her. Haibara ''claims'' she simply admires him, but her actions are much more like those of a young lovestruck girl. Chapters 925-927 features Ai suffering a borderline BSOD when she learns that Higo might have hooked up with Yoko Okino, and when both Yoko and Higo are involved in a case, she butts heads with Kogoro and Yoko more than once. Professor Agasa has said Haibara's attitude regarding Higo reminds him that there's still an otherwise normal girl under that cold exterior.
* NotSoStoic: First seen when she breaks down in front of Conan because he could not save her sister from being killed by the Organization.
* OlderThanSheLooks: Shrunk in the same manner as Shinichi, down to a 6-year-old's body. PlayedForLaughs when Conan first asks her real age. She flatly states 84, throwing Conan for a loop. [[spoiler: She only kept up the joke for one panel, but it was worth it to see Conan's surprise and bafflement.]]
* PetTheDog: With literal dogs and some cats.
* TheQuietOne: Haibara tends to be quiet, though this may be due to her caution to keep herself hidden from the Black Organization.
* SecretIdentity: Her real name is Shiho Miyano.
* SecretKeeper: One of the few people who knows that Conan is Shinichi, she also hid this from TheSyndicate while she was still a member because she thought him an interesting subject to watch.
* ASharedSuffering: She has confessed to Conan that having him around in the same situation as her is why she can stand being a six-year-old.
* ShipperOnDeck:
** She gives a knowing, sly smirk to Agasa (along with the rest of the Detective Boys) after the latter's meeting with his FirstLove, Fusae Campbell-Kinoshita.
** Doesn't exactly mind [[spoiler: Satou and Takagi]] getting together.
