Conan Edogawa/Shinichi (Jimmy) Kudo
"Voiced by:

As Shinichi/Jimmy: Kappei Yamaguchi (JP)/ Jerry Jewell (EN)

As Conan: Minami Takayama (JP)/ Alison Retzloff (EN)"

Dubbed the "Heisei Holmes" (Heisei being the current "era" of Japanese history), sixteen-year old Shinichi was well-known throughout the Beika District of Tokyo and beyond for being able to solve any crime that the police failed to. However, he was still a teenager, and susceptible to things such as... oh, falling in love with his childhood friend Ran.

One day, after solving a murder at an amusement park, Shinichi comes upon a mysterious man in black extorting money from another man. While he's investigating, however, he fails to see the man's partner sneak up on him and knock him out cold with a metal pipe. Deciding that He Knows Too Much, the two force-feed him a poison pill supposed to not only kill him, but leave no trace behind besides "evidence of a spontaneous heart attack". Unfortunately for them, it fails to do the former, and only half-accomplishes the latter: Shinichi has been shrunk into a six-year old.

One quick visit to his neighbor Professor Agasa's house later, Shinichi realizes that he must keep his identity secret, lest the two men in black come back and kill him for good. He is adopted by Ran, and now lives at the Mouri Detective agency, much to his (at first) dismay. Every once in a while, he has picked up leads on the two men in black, but in the meantime... murders, thefts, and kidnappings are popping up all around, and what better way to pass the time than to solve them all?

Mandatory naming note: "Shin'ichi" has various possible spellings - the one used here is 'new one', possibly referring to his being the 'Holmes of the Twentieth Century/New Era', but may also be a reference to the Japanese writer Shinichi Hoshi. "Kudo" came from Shunsaku Kudo of Tantei Monogatari.

Tropes associated with him:


 * Accidental Pervert: Most apparently in the Hot Springs Episode when he nosebled, but also in some of the other situations-- his not-girlfriend did not know his identity and did a few things that would be appropriate in front of a pre-teen, but not a boy her own age(which is rather funny; technically Conan's gotten further with Ran than Shinichi has).
 * He actually was this in the first episode already. He forgot that he promised to take Ran out on a date to an amusement park, and when she tried to kick him in the head for that, she ended up giving him one Hell of a Panty Shot... when he tried to dodge and ended up with his head under her skirt. He then got a face full of school-bag for his trouble.
 * Adorably Precocious Child: Appears to be one as Conan.
 * Adorkable: In the beginning of the series the only clothes he's seen wearing are his miniature suit, complete with a bow tie. This combined with his cute ways of expressing his feelings and his Sherlock Holmes obsession create top quality Adorkable material.
 * Almighty Janitor: Conan is just a kid (in appearance, at least), and nobody ever listens to kids, at least not for a couple of chapters. New officers usually react this way towards him, but those who know him always appreciate his input. Once he has solved a crime, he usually has to resort to his tranquilizer wristwatch and voice-changing bow tie in order to relay his deductions through a handy field-expedient ventriloquist's dummy.
 * Amateur Sleuth
 * Berserk Button: Do not ever harm anyone he cares for. But especially his beloved Ran. He can be quite jealous when someone merely shows possible romantic/sexual interest in Ran, but if you ever look at her wrong...
 * Also, among all the murderers and criminals he deals with, Conan absolutely loathes Yanderes and Cute Psychos. Criminals of such types often get the most scathing, harsher "Shut UP, Hannibal" speeches from him.
 * Born Detective: His dad writes mysteries. And has brought him to murder scenes ever since he was little. And an OVA showed him solving cases at one year old. Figures.
 * In the OVA, he actually seems to be doing things just to lead his mother into a Eureka Moment...oddly enough, one of his tactics today.
 * Blind Without'Em: Invoked to maintain his Clark Kenting (see below). The dub made it one step further by making dub!Conan say he has retinitis pigmentosa.
 * Cassandra Truth: No one believes Conan when he tries to help, and that's why he uses Kogoro, Sonoko, etc. This was later subverted by several adults, who even without knowing his secret either recognize his ability without asking too many questions (Satou particularly), or at least acknowledge his uncanny (and faked) habit of creating Eureka Moments.
 * Catch Phrase: A few of them.
 * "Edogawa Conan, tantei sa!"
 * "Shinjitsu wa itsumo hitotsu!" (Or its American counterpart: "With a keen eye on details, one truth prevails!")
 * "Ah re re"
 * Conan also has Oi, Oi. There are two fan videos consisting of him saying/thinking the phrase "Oi, oi."
 * "Barou!" (as in "Ba(ka-ya)rou!")
 * Character Name Alias
 * Chronic Hero Syndrome: He can't leave a case unsolved and any hint that a crime might occur in the future has him trying to prevent it. This is lampshaded by several characters, including Ran and Ai.
 * Clark Kenting: After being shrunk to a grade-school kid, the title character does the same thing as Clark Kent: wears a pair of glasses (was his father's) to hide his identity. It usually works well, until he slips up and says information he shouldn't have known unless he was really Shinichi Kudo, who was supposed to be a distant relative. This leads to Ran becoming suspicious of him several times, but she always ends up discrediting her own finds because the evidence doesn't quite match up, due to some outside interference (usually planned by the protagonist himself). In one scene, when
 * According to an interview with Gosho Aoyama, the glasses really were based on Superman.
 * Constantly Curious: Conan routinely interrogates suspects by pretending to be an obnoxiously curious kid, at least for as long as he can pull it off without being scolded. The Detective Kids behave like this at times as well, though in their case they aren't pretending. Sometimes Conan uses this trick to pass information to the adults (usually Kogoro) to allow them to solve the case if he can't or doesn't want to use the Stun Gun Watch.
 * Deadpan Snarker: He mainly snarks the Detective Boys, Kogoro, Ran etc.
 * He snarks everyone, actually, if they ever act or give some comments which he considers stupid.
 * Deliberately Cute Child: Conan often does this to throw people off from suspecting he's really seventeen year old Shinichi Kudo. Though he can on occasion take it too far and has a time or two been called out by his kid friends for doing it.
 * Gadget Watches: His include a stun gun and a torch.
 * Genre Savvy: Has read all the great detective stories and knows their tropes by heart.
 * Goggles Do Something Unusual: Conan's glasses have been given upgrades throughout the series. Initially they contained a screwed-in GPS bug that could be taken out and placed elsewhere while the glasses tracked the device's location with its own minimap. Agasa later replaced the glass with bulletproof glass and the bug was updated with listening functions and its own frequency. The listening device is also designed so it "Stimulates the eardrum," thus only the wearer can hear it.
 * Hollywood Tone Deaf: He has perfect pitch but simply can't sing.
 * In the manga he is completely unable to translate the notes he hears into music using an instrument or his voice himself; in the anime, however, he has enough skill for his own very awkward-sounding (to this musically-qualified troper) theme tune and one song on the violin - since he's such a huge Sherlock Holmes lover that he would try it himself. Note that Holmes himself was never at all accomplished at the violin and merely played how he felt at the time.
 * Hyper Awareness
 * Identity Impersonator: As Ran often comes close to discovering Conan's identity, he has found a couple of ways to have "Shinichi" on the phone when Conan is in the room. The masterstroke came one time when he was in his original body and Ai disguised herself as Conan.
 * Improvised Weapon User: His only weapon of assault is his super shoes that only increased the power of things he kicked on. Sometimes, strange results would happen: he tried to kick a cabbage, but it broke immediately. The other time he had to kick an entire hospital bunk-- well, got the villain, but sprained his ankle in the process.
 * Inner Monologue: Conan does this all the time. In some dubs, including the American dub, this inner monologue is even in Shinichi's voice!
 * Intelligence Equals Isolation: Not as bad as Hiroki Sawada, but as Shinichi he had some issues in regards to relationg to people. More than once his classmates and teachers would remark on him being arrogant and hard to approach, with Ran as almost the only exception.
 * Limited Wardrobe: In the earlier part of the series, Conan nearly exclusively wore a blue suit, a white shirt, and a red bowtie. Later he was seen with a better variety of clothes.
 * Line-of-Sight Name: Shinichi came up the name Conan Edogawa by seeing books of mysteries by Arthur Conan Doyle and Edogawa Rampo.
 * Meitantei: Why, the Japanese title is Meitantei Conan.
 * Lonely Rich Kid: After his parents moved to the US. That said, this does not induce I Just Want to Have Friends but rather enforced his Otaku image.
 * The Mind Is a Plaything of The Body: Averted.
 * And then she appears as herself for two episodes, both in the manga and the anime adaptation. The Detective Boys quickly point out the similarity between their voices, and the irony given by the contrast between Shin'ichi/Conan's Hollywood Tone Deaf status and Minami's Idol Singer talent.
 * Must... Have... Caffeine...: He is commonly depicted as one in fanon.
 * My Greatest Failure: The Moonlight Sonata case.
 * Mystery Magnet: Poor kid can't go anywhere without a murder happening. Occasionally lampshaded--the police inspector, upon realizing that Detective Mouri just HAPPENED to be near when the crime occurred, has a tendency to raise his eyebrow and vocalize his incredulity. Sadly, he never seems to follow up on this.
 * New Powers As the Plot Demands: He always has previously unmentioned special skills in Non Serial Movies, conveniently explained away by "my dad taught me at Hawai'i." Attained Memetic Mutation status, at least in Taiwan. Lampshaded in this fanfic.
 * Nosebleed: Conan gets some of these during Accidental Pervert situations.
 * Not Now, Kiddo: Nobody ever listens to kids. Early on, Conan has to use Professor Agasa's voice-changing necktie just to tell the police to look under a table.

It has been averted slightly as time goes by in that most of the police inspectors eventually learn to pay attention to Conan's observations--and some even recognize the kid's innate intelligence rather than thinking he is just accidentally inspiring them.
 * Not So Above It All: He has picked up some of Kogoro's most annoying habits. Hilariously seen in the Masami Hirota case: when the stranger that Ran caught took off his sunglasses, they started laughing in exactly the same way and at the same time.
 * OTOH, he once started a'hootin' and a'hollerin' when his favorite soccer team won a big game, prompting Haibara to snark that "the Master Sleuth was just a jumpy little boy when it came to soccer."
 * Obfuscating Stupidity: Conan repeatedly makes a very awkward use of this to disguise his investigations and artificial Eureka Moments. This usually consists of Conan making a very adult speech or explanation, followed by everyone looking strangely at him, followed by Conan hastily saying in deliberately-cute mode, "At least, that's what I saw on TV!" In general, he gets away with it more because he looks like a child than his questionable acting skills.
 * Oblivious to Love: A minor example; in a strange reversal of his usual eye for small details, Conan usually completely fails to notice the few occasions when Ai expresses her jealousy of his relationship with Ran.
 * Older Than They Look: Main premise of the show.
 * Otaku: Em, some of classmates would rather call him suiri-otaku (mystery geek), especially Sonoko. Ran also tends to use it as an insult when's irritated with his supposed preoccupation with difficult cases causing his prolonged absence.
 * Parental Abandonment: His parents moved to the United States two years before the stories; mainly in Los Angeles but also seen in Hawaii and New York. He still keeps contact with them and they've helped him out more than once, though.
 * Secret Identity: He FAILS to keep it well, while still succeeded in keeping it. Specifically, as advised by Dr Agasa, Conan Edogawa must hide the fact that Kudo Shinichi survived poisoning by the Organization in order to protect the safety of friends, family, and loved ones.
 * Except, all things considered, he seems to be doing a pretty lousy job of it, as Conan is unable to keep from appearing too clever for his own good. Not only does he (as Shinichi) regularly telephone Ran, but he also telephones Inspector Megure (as Shinichi) from time to time to drop clues (but makes sure the police officers know not to tell anybody about his involvement). It seems to be a fairly open secret as of episode 250 that Kudo is in frequent contact with the Mouri Detective Agency.
 * Certainly, other clever people take notice. When even Ran is able to figure out that Conan is Shinichi (several times over the course of the series), that can be a problem. (And it doesn't help matters that Heiji is prone to calling Conan "Kudo" even when in the presence of others.) In "Trembling Metropolitan Police Headquarters: 12 Million Hostages" even Takagi asks Conan "who [he] really [is]". If you cannot even keep the fact that you are concealing your true identity secret from Takagi, you FAIL at secret identity.
 * Moreover, every time a case with Kid comes up, Conan is treated by the media as Kid's nemesis, effectively making him a celebrity. This would likely be detrimental to keeping a secret identity given that he looks exactly like a young Shinichi Kudo and the Organization is already suspicious of everything surrounding Kogoro--but luckily for him, any of his accomplishments and fame are completely forgotten in any chapter not starring Kid, only to come back next time the thief shows up.
 * The fact that Conan's identity remains secret from the Black Organization is probably attributable more to luck (and script immunity) than skill. The members of the Black Organization who have uncovered the truth about Conan's and/or Ai's shrinkage either had their own reasons for not divulging it to the rest of the group or were killed before they could do so . The one other member of the group who might be intelligent enough to figure it out, Gin, is handicapped in that he makes a point of not remembering the people he's killed; he probably forgot who Kudo Shinichi was five minutes after feeding him the poison. (Also, Conan has somehow managed not to directly catch his eye.)
 * Shorter Means Smarter: Look at his height compared to the other Detective Boys.
 * The Short Guy With Glasses: Conan was the second shortest member of the regular cast, shorter than Ayumi. Subverted as Shinichi; he is of normal height for his age.
 * Significant Birth Date: Shinichi's birthday is 4th of May, the day when Sherlock Holmes and Dr. Moriarty supposedly fell of the Reichenbach falls.
 * Single Target Sexuality: Shinichi's pretty much Ran-sexual, as the arc with Asami suggested.
 * Surrounded By Idiots: Oi, oi. Lowered eyebrows optional.
 * Teen Genius: Limited similarity to Sherlock Holmes' field of knowledge; he certainly knew all that knowledge for all his cases, but he was not shown to be that good academically. (Of course, he's not Kindaichi bad.)
 * Thou Shalt Not Kill: He found the Moonlight Sonata case (see Narumi Asai, below) as His Greatest Failure.
 * Tricked Out Shoes, which that deliver an electric current through his legs. This greatly enhances his kicking ability.
 * Wimpification: Certainly Detective Conan is not a Boys Love series, but Shinichi/Conan is universally considered being Uke to practically everyone for all Yaoi Fangirls of the series. It might be really jarring to see Conan being uke to Hiroki (see below), who may have more uke stereotypes than Conan is.

Ran Mouri/ Rachel Moore
"Voiced By Wakana Yamazaki (JP)/ Colleen Clinkenbeard (EN)"

Mandatory name note: The entire name came from Maurice Leblanc, creater of Arsène Lupin, through the Japanese reading Mooritsu Ruburan.

Tropes associated with her:

": You are crying again... You are always crying."
 * Action Girl: She's actually got a good record for getting herself out of scrapes with criminals, no matter what the rabid Conan/Ai fans say. Justified, as she's a national karate champion.
 * Badass in Distress: More in The Movies. As mentioned, rabid Ai/Conan fans use this to falsely accuse her of being a Faux Action Girl. It should be noticed that when the Distress Ball is whacked away from her, she recovers fast; i.e., in Captured in Her Eyes,
 * Almost Kiss: Subverted, they did. She also almost has one with Kaito but...(see below)
 * Played straight in Canon; the Almost Kiss is only subverted in the non-Canonical Movies, while there are several instances of this trope in canon that have yet to be resolved for Ran.
 * Barbie Doll Anatomy: 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 vulnerability from being kept apart from Shinichi for so long.
 * Big Sister Instinct / Mama Bear: Don't try to kill Conan with her in the vicinity.
 * Not only Conan, either. Don't threaten anyone she loves, period.
 * Charles Atlas Superpower: Through nothing but a harsh, disciplined training in karate that has dominated most of his life, Makoto Kyogoku can defeat a small army of hired thugs, knock out armed criminals and dodge bullets. Through nothing but karate lessons she takes occasionally while otherwise leading a normal girl's life, Ran Mouri can do all that as well. Even the bullet thing, at least in one of the movies. Don't think about it too hard.
 * With Ran, it could also be a slight case of It Runs in The Family. At least home schooling has been mentioned, and both Kogoro and Eri know their Judo pretty well.
 * Children Raise You: For Kogoro, her Adult Child father.
 * Cute Bruiser: Plays karate on the national level. Dere-dominant Tsundere. For proof: there's an episode where It took 12 minutes, and not a hair was out of place.
 * Even the Girls Want Her: If we take Sera's "she's just my type" seriously.
 * Friend to All Children: 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, but that's because ; she later warms up to her too.
 * Hello Nurse: Men often pick her up instead of Sonoko. To the chagrin of the latter.
 * Identical Stranger: In the DC vs. Lupin III special, with
 * I Know You Know I Know: Know Shinchi very well, as the last time Kaito disguised himself as him she knew he is fake.
 * Light Feminine and Dark Feminine: When not in tsun-tsun or Action Girl mode, kind and gentle Ran is an example of Light Femininity.
 * Loves My Alter Ego: Inverted. She loves Shinichi (the original person), but she does care for Conan (new identity).
 * No Sense of Direction: Really.
 * Tender Tears: Lampshaded by


 * Tsundere: She's default Type B or deredere (gentler). Just don't piss her off.
 * Why Did It Have to Be Snakes?: 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.
 * Zettai Ryouiki: Sports the look from time to time. It's quite noticeable in the first OP, where she sports a Type A... if she added Twin Tails, her Type B Tsundere traits would give her a Grade S.

Kogoro Mouri/ Richard Moore
"Voiced by Akira Kamiya / Rikiya Koyama (JP)/ R. Bruce Elliot (EN)"

Mandatory naming note: "Kogoro" came from Kogoro Akechi, the Great Detective in Rampo Edogawa's novels.

Tropes associated with him: Given that Kogoro's lechery seems more talk than action, and he was presumably monogamous with Eri until they parted after 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.
 * Adult Child: Sometimes, his daughter Ran acts more like his wife or mom.
 * Adults Are Useless: Well, considering that Shinichi/Conan and other teen detectives are in general more competent and active than everyone...
 * Alcoholic Parent
 * Aw, Look -- They Really Do Love Each Other: 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. At one point, Kogoro even outright states that he cannot bear being seperated from Eri and asks her to come back, but she pretends she didn't hear him because she's not ready yet.
 * Can't Act Perverted Toward a Love Interest: 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.
 * Badass Moustache
 * Brilliant but Lazy/Genius Ditz: 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.
 * Bumbling Dad: To Ran and Conan. Basically a loser, but his care towards his daughter Ran is utterly remarkable.
 * Butt Monkey: If something funny, humiliating or painful is going to happen, the first-rate candidate is Kogoro.
 * Clueless Detective: Usually jumps to the most obvious deduction, frequently the one the culprit wanted the investigators to believe. He never bothers to look for further evidence or question his conclusions after that, which is why he almost never finds the correct solution.
 * Crouching Moron, Hidden Badass: VERY sparingly, 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. Granted, since this happens like thrice or so in fifty volumes, it's very easy to forget.
 * Defective Detective: 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 Played for Laughs or Drama.
 * Famed in Story: 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.
 * Fan Boy: Of Idol Singer Yoko Okino.
 * Promoted Fanboy: 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 appeareance in her cooking show and would have starred in another show hosted by her if it hadn't got the axe.
 * Hey It's That Voice: Before he was a private detective, he was freaken Kenshiro.
 * And he also was Mamoru motherfucking Takamura.
 * Now he's JAAKU BAUWA!
 * In-Series Nickname: "Sleeping Kogoro." This of course refers to the effect of Conan's sedation dart, but is also a Shout Out to Katsura Kogoro (aka Kido Takayoshi), who was also known as the "Fleeing Kogoro."
 * Lovable Sex Maniac: 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.)
 * Mr. Vice Guy: 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 Lovable Sex Maniac, as he was also the voice actor for City Hunter Ryo Saeba. (In another character's thought balloon in one of the OAVs, Kogoro even used Saeba's Catch Phrase "mokkori".)
 * The Other Darrin: Rikiya Koyama replaced Akira Kamiya as the latter retired to be a seiyuu trainer.
 * Overprotective Dad: 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.
 * Private Detective: Most of the detective characters in this series are 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.
 * Sharp Dressed Man: 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.
 * Small Name, Big Ego: Though, in his defense, Conan lets him take the credit for solving the cases.
 * Smart Ball: 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.

Ai Haibara/ Anita Hailey (Viz Media)/ Vi Graythorn (FUNimation)
"Voiced by Megumi Hayashibara (JP) / Brina Palencia (EN)"

Mandatory naming note: Haibara came from Cordelia Gray; Haibara literally meant Grayfield. Ai came from flipping the V in V.I. Warshawski-- the kanji usually associated with the sound "Ai" means love, but she took the alternative for "sorrow."

Tropes associated with her:
 * Acting Your Intellectual Age: For an in-universe bystander, she is this.
 * All of the Other Reindeer: Got her education in America, where she was picked on for her Japanese features.
 * Better to Die Than Be Killed: She attempted this when she locked up for betraying The Syndicate, rather than facing execution. She took a poisonous drug she created, but instead of dying she suffered its other effect, which 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.
 * Broken Bird: Her choice of a pseudonym underscores this. As said before, the kanji for "Ai" doesn't mean "love", but "sorrow".
 * But Not Too Foreign: Ai's mother Elena was British.
 * The Chessmaster: The stint in Volume 26 of the manga established that.
 * Child Prodigy: 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.
 * Chronic Hero Syndrome: 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.
 * Creepy Child: 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.
 * Cuteness Proximity: Animals bring out the "sugar" of her Sugar and Ice Personality.
 * Dark and Troubled Past: Inevitable, having been raised by the Organization.
 * Dead Little Sister:
 * Death Seeker: Believing that it's only a matter of time for The Syndicate 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 in exchange for her promise that no one else will be harmed, but is rescued again.
 * Deliberately Cute Child: Averted. Unlike Conan, Haibara never bothers with this. The one time she did, in one of the movies, it freaked Conan out something fierce.
 * Distressed Damsel: Occasionally, for example when Conan has to save her from Pisco, Gin and Wodka.
 * Eating Lunch Alone: She claimed she was that when she was in school. Not surprising.
 * The Fashionista: 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.
 * Friendless Background: 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.
 * Genre Savvy
 * Guile Heroine
 * Heel Face Turn: 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.
 * Hidden Eyes: When we see her adult form in flashbacks, her eyes are usually covered by Blinding Bangs or otherwise hidden.
 * Hot Scientist: In her older form. As a child, her classmates find her very cute, but of course have no idea that she's a scientist.
 * Improbable Age: Reconstructed. She led the Organization's poison lab before she was shrunk-- that was when she was 18. She does not enjoy the Intelligence Equals Isolation 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.
 * Intelligence Equals Isolation: One of the reason she's not willing to change back.
 * Jerkass Facade: Justifies many of her more altruistic acts with pragmatic, self-serving motives.
 * Last-Name Basis: 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.
 * Little Miss Snarker: She mainly snarks Conan.
 * The Mind Is a Plaything of The Body: Even more averted than Conan.
 * Non Action Snarker: 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.
 * Well, she is a pretty crack shot with guns, especially pistols. She just doesn't get many opportunities to use them.
 * Not So Above It All: Usually either serious or snarky, but she does have the odd moment of sillyness.
 * Not So Stoic: First seen when she breaks down in front of Conan because he could not save her sister from being killed by the Organization.
 * Older Than They Look: Shrunk in the same manner as Shinichi.
 * Parental Abandonment: Her parents, Atsushi and Elena, died when she was very young. She was raised by the organization.
 * Pet the Dog: With literal dogs and some cats.
 * Secret Identity: Her real name is Shiho Miyano.
 * Secret Keeper: One of the few people who knows that Conan is Shinichi, she also hid this from The Syndicate while she was still a member because she thought him an interesting subject to watch.
 * Shared Suffering, A: She has confessed this is why she can stand being a six-year-old.
 * Stepford Snarker: Her Little Miss Snarker persona masks some DEEP issues, starting with the murder of her sister Akemi, and the constant fear of being found by the The Syndicate.
 * Sugar and Ice Personality
 * Teen Genius: She's at least as smart as Shinichi, she just doesn't get to show it as often because her field is science and the story centers on detective mysteries.
