[[folder: Dr. Hiroshi Agasa]]
->''Voiced by Creator/KenichiOgata (JP)'', Guillermo Romano (first Latin American Spanish dub), Jaime Vega (second Latin American Spanish dub, movies 1 and 2 only), Mario Santander (third Latin American Spanish dub)

Shinichi's next door neighbor who makes a living developing odd inventions; some of which are put to use by Shinichi throughout the series. Shinichi appears to have the utmost trust in him, having no problem of revealing his identity to Agasa only moments after being shrunk by the APTX-4869 pill.

Later on, most of his appearances amount to playing the adult who looks after the Detective Boys, becoming the unintentional guardian of Ai Haibara (aka Shiyo Miyano) when said character shows up at Shinichi's doorstep, and providing insight for Shinichi to help combat the Black Organization.

During most cases that involve the Detective Boys, Shinichi will force Agasa into the spotlight to explain the case at hand.

[[ThemeNaming Mandatory Naming Note]]: "Agasa" is the {{Engrish}} pronunciation of ''Agatha'' Christie.[[labelnote:Phonological Note]]JapaneseLanguage lack the [[http://en.wikipedia.org/wiki/Voiceless_dental_fricative Voiceless Dental Frictive consonant]], i.e. the "th" sound. They pronounce the "th" as "s."[[/labelnote]]

DubNameChange: Hershel Agasa.
* AbsentMindedProfessor: Most Triumphant Japanese Example.
* BadassBookworm: While Professor Agasa doesn't engage in any violence in the series, he ''does'' create all of Conan's helpful and amazing gadgets.
* BigFancyHouse: The mansion located next to the just-as-big Kudo home.
* BigFun: A chubby old man with a heart of gold and a cheerful disposition
* BunnyEarsLawyer: His number one talent is inventing.
* EinsteinHair: Matches perfectly with his inventing skills.
* FriendToAllChildren: Frequently takes the Detective Boys out for fun.
* GadgeteerGenius: He made Conan all those [[strike:assistive technology]] gadgets.
* HerrDoktor: Drives a German car, a Käfer. In the dub, he has a German accent.
* NiceGuy: One of the nicest in the series.
* NoNameGiven: Averted, but not with a bit of AssPull. His given name, given as Hiroshi only later on, is an AlternateCharacterReading of ''Hakase'', the Japanese term for the title of Doctor, while devoid of the latter's connotations.
* OnlyFriend: He was this to his childhood friend, Fusae Campbell Kinoshita; he was the only one among their peers who didn't viciously tease about her {{mixed ancestry}}.
* ParentalSubstitute: For Shinichi, to a degree. Even moreso for Haibara, who lives in his house and unlike Shinichi, no longer has any real family. She grows to love him like a real father and often tries to protect him above anyone else. He's even her cellphone background picture! [[spoiler: It turns out he knew her dead parents.]]
* SecretKeeper: With the distinction of being the first person ''ever'' who found out about Shinichi shrinking into a child, who later became "Conan Edogawa".
* SmartBall: Pocketed it. Shinichi said he never invented anything useful right in the beginning, yet he eventually became one of the most GadgeteerGenius in anime [[AssPull without any further explanation]] (to the point where ''actual secret agents'' express jealousy at his skills). That being said, several of his inventions still do malfunction from time to time, but those are few and far between.
* SmartPeopleWearGlasses: Sports circular glasses and is a brilliant inventor.
* StarCrossedLovers: [[spoiler:With Fusae Campbell Kinoshita.]]
* TrademarkFavoriteFood: Agasa has a special love for pasta and tomato juice.

[[folder:The Detective Boys]]
[[caption-width-right:259: From left to right; Mitsuhiko, Haibara, Conan, Ayumi, and Genta.]]

Consisting of Conan, Haibara, Mitsuhiko, Genta, and Ayumi, they are a FiveManBand of kid detectives.

[[ThemeNaming Mandatory Naming Note]]: Their group name comes from the group of the same name in Edogawa Ranpo's novels.

DubNameChange: The Junior Detective League.
* FiveManBand:
** TheLeader: Conan (Conan leads the investigations, but Genta insists on the credit.)
** TheLancer: Haibara, like Conan, is a genius adult shrunk to child form but her coldness contrasts his heroics.
** TheSmartGuy: Mitsuhiko ''thinks'' he's the smartest because he's LockedOutOfTheLoop. He provides information Conan lacks.
** TheBigGuy: Genta, the tallest and strongest (and chubbiest) of them.
** TheChick: Ayumi is a cheerful girl who's friends with everyone; even FirstNameBasis with Haibara.
* FreeRangeChildren: The kids spend a lot of time wandering around without even nominal adult supervision. They regularly do things like take bus trips, canvas neighborhoods, and explore caves, forests and scary mansions alone. True, Conan and Ai are OlderThanTheyLook, but almost any adult who isn't [[SecretKeeper Professor Agasa]] doesn't know that since Conan and Ai look about seven.
* LimitedSocialCircle: They are rarely seen spending much time with classmates outside their group but Ayumi at least is shown with a list of her other friends. [[JustifiedTrope Justified]] with Ai and Conan, who simply don't have any reason to make more friends at elementary school.
* LoveDodecahedron: Genta likes Ayumi, Mitsuhiko likes Ayumi and Ai, Ayumi likes Conan, Ai is believed to like Conan and Conan is Ran-sexual.
* ObliviousToLove: Among the group, Ayumi is blissfully unaware that Mitsuko and Genta both have a huge crush on her. Conan knows Ayumi likes him, but dismisses his mother's suggestion that Ai also has a crush on him as absurd.
* [[ShipperOnDeck Shippers on Deck]]: All of them prefer that Takagi and Satou became a couple. And after discovering that [[spoiler:Kobayashi]] is [[spoiler:Shiratori's "girl of destiny"]], they all were anxious for them to become a couple.
* {{Snooping Little Kid}}s: The group together is mostly seen as this to grown-ups; particularly, the police department and Kogoro.
* [[SheIsAllGrownUp They Are All Grownup]]: OVA 9.
* {{Tag Along Kid}}s: Conan is pretty much followed by the three actual kids of the group, Mitsuhiko, Genta and Ayumi. Ai on rare occasions takes Conan's place here sometimes. Otherwise, she stands along side Conan.

[[folder:Ayumi Yoshida]]
->''Voiced by YukikoIwai (JP) / MonicaRial (EN)'', Erika Araujo (first Latin American Spanish dub), Claudia Mota (second Latin American Spanish dub, movies 1 and 2 only), Ximena Marchant (third Latin American Spanish dub)

The one and only emotional girl of the Detective Boys before Ai Haibara joined the group later in the series.

DubNameChange: Amy Yeager.
* TheCutie: Most of the time.
* FirstNameBasis: Ayumi is the only child of the group who calls Haibara by her first name.
* HairDecorations: Always seen with a headband.
* HopelessSuitor: For Conan, due to the latter age problem. Though to her defense, it's more like admiration than crush.
* NiceGirl: Ayumi is shown to be a very brave girl and acts as the group's cheerful spirit.
* TheSmurfettePrinciple: She was the only girl of the group before Haibara joined.
* ThirdPersonPerson: In later chapters, Ayumi constantly refers to herself as such.
* TokenMiniMoe: Pretty self explanatory seeing how any other major or secondary female character in the series is either a teenager or an adult not counting the shrunk Haibara.

[[folder:Genta Kojima]]
->''Voiced by Creator/WataruTakagi (JP)'', Victor Mares Jr. (first Latin American Spanish dub), Creator/JesusBarrero (second Latin American Spanish dub, movies 1 and 2 only), Alberto Salas (third Latin American Spanish dub)

The big kid of the group who enjoys to eat, but isn't the brightest of the bunch.

DubNameChange: George Kaminski.
* BigEater: Eats a lot for his age. Although he ''is'' fat.
* BigOlEyebrows: Has thick eyebrows.
* BridalCarry: Give one to Haibara in Movie 5 to stop her SenselessSacrifice.
* DumbMuscle: Seen to be the least intellectual of the group, but at least makes up for it for being the biggest and the strongest of the Detective Boys.
* JerkWithAHeartOfGold: Even though he is brash, outspoken and can be intimidating, Genta is actually very kind and dependable.
* OOCIsSeriousBusiness: During the ''Tragedy of the Pier in Plain Sight'' case (episodes 366-367/volume 45), his uncharacteristic action of fully concentrating on fishing (to the point of almost skipping lunch) turns out to be a secret plan to catch a rare fish for Professor Agasa's birthday.
* SensitiveGuyAndManlyMan: The loud, tough Manly Man to Mitsuhiko's thoughtful, organized Sensitive Guy.
* TalkingtoHimself: On rare occasions if Takagi and Genta are in the same episode. Both share the same voice-actor in Japanese.
* TrademarkFavoriteFood: Unajuu, or eel on rice.

[[folder:Mitsuhiko Tsuburaya]]
->''Voiced by Creator/IkueOtani / Creator/AiOrikasa (JP)'', Ivette Gonzalez (first Latin American Spanish dub), Miguel Ángel Ruiz (second Latin American Spanish dub, movies 1 and 2 only), Carolina Araya (third Latin American Spanish dub)

The lead boy before Conan joins the group who genuinely tries to provide Conan with legitimate feedback on cases that the group comes across; most of the time to no avail.

DubNameChange: Mitch Tennison.
* AuthorAvatar: Gosho Aoyama has stated in an early interview that [[TheSmartGuy Mitsuhiko]] is modeled after his childhood self.
* DoesNotLikeSpam: Mitsuhiko has shown a dislike towards carrots.
* LovableNerd: Seen to be smartest of the children outside Conan and Haibara.
* NiceGuy: Mitsuhiko has shown to be a consistently polite young man. Due to his strict and formal upbringing by his parents, he tends to be very formal towards his elders, addressing them (in Japanese) with the formal suffix "-san" without regard to the intimacy of their relationship.
* SensitiveGuyAndManlyMan: The thoughtful, organized Sensitive Guy to Genta's loud tough Manly Man.
* WiseBeyondHisYears: Can be argued that Mitsuhiko acts quite sharp and clever for his age. One episode even has ''HIM'' solving the case!
* YouthfulFreckles: Notable the only Detective Boy who has this.

[[folder:Sonoko Suzuki]]
->''Voiced by Creator/NaokoMatsui (JP) / Creator/LauraBailey (EN)'', Rocío Gallegos (first Latin American Spanish dub), Sandra Pavón (second Latin American Spanish dub, movies 1 and 2 only), Josefina Becerra (third Latin American Spanish dub)

The love-seeking daughter of a very rich family, and Ran's best friend. On rare occasions, mostly from cases that involves just her and Ran, Shinichi will put Sonoko to sleep and talk as her in a manner similar to how he uses Kogoro as the scrape-goat for explaining the case at hand.

She eventually gains an actual boyfriend in the form of an international karate champion, Makoto Kyougoku, but still finds time to flirt with other men (Kaitou Kid in particular) to compensate for the fact that she can't handle being in a long-distance relationship.

DubNameChange: Serena Sebastian.
* AllGirlsWantBadBoys: Subverted. While she's a big fan of [[PhantomThief Katiou Kid]], it doesn't go anywhere deep and she's [[SingleWomanSeeksGoodMan already in love]] with [[GentleGiant Makoto.]]
* AlliterativeName: '''S'''onoko '''S'''uzuki. Also counts with her dubbed name ('''S'''erena '''S'''ebastian).
* AloneWithThePsycho: At least twice.
* BerserkButton: Say all you want about this girl, but she strongly believes in ThePowerOfFriendship and adores her buddies -- specially Ran. So please don't harm your own friends! And even more so, [[spoiler: '''don't kill them'''.]] She will get REALLY mad if you do.
* BrainlessBeauty: Borderline case.
* BullyHunter: As a child, Sonoko used to defend Ran from bullies.
* ButtMonkey: She really has extraordinarily bad luck at times.
* ChildhoodFriends: With both Ran and Shinichi.
* DamselInDistress: Catches the DistressBall more than once.
* {{Fangirl}}: Goes crazy when Kaitou Kid makes an appearance.
* TheFashionista: Especially seen in one case where Sonoko identifies the victims as belonging to the ''[[http://en.wikipedia.org/wiki/Ganguro ganguro]]'' fashion sub culture upon seeing their pictures. She even distinguished ''what'' kind of ganguro they were!
* ForeheadOfDoom: Often noted to have a big forehead.
* HairDecorations: Usually seen with a headband.
* HeterosexualLifePartners: Ran Mouri's closest friend since childhood.
* JerkWithAHeartOfGold: With all of her shallowness and childish fits, she really cares for Ran, Makoto, her friends and family.
* LongDistanceRelationship: With Makoto, a famous karate champion.
* OfficialCouple: With Makoto Kyougoku.
* PluckyGirl: She never ever gives up on what she wants.
* RunningGag: Her bad luck with men, until she started dating Makoto.
** Goes into NotFunnyAnymore in 153-154, where she goes boy-hunting in Izu (with Ran and Conan in tow)...and the attractive boy who showers her with compliments turns out to be the {{AxCrazy}} [[MonsterOfTheWeek killer of the week]], driven by a hatred for blonde girls. [[RescueRomance She is rescued by Makoto, which marks the start of their relationship.]]
* SheIsAllGrownUp: In the ''Stranger of 10 Years Ago'' OAV, she's not only OlderAndWiser but is almost as much of a Type 1 {{Ojou}} as Ayako.
* ShipperOnDeck: After being an [[ShippingTorpedo antagonist against Ran/Shinichi]], she practically refers to the couple as Husband/Wife, and about sending pictures to Shinichi regarding Ran to either make him blush or jealous.
** Sonoko laters ships the HELL out of Officers Takagi and Satou. In fact, is PISSED [[http://33.media.tumblr.com/405e6dc8c0fe7c4dc35767729747024f/tumblr_n5yuxufpJV1qgf1bho7_500.gif when Conan]] [[MomentKiller interrupts]] what [[AlmostKiss could have been]] Takagi and Sato's FirstKiss...
** Sonoko also seems to think that Conan and Ayumi would be cute together.
* ShippingTorpedo: For a long time she's a Shinichi/Ran ''anti''-shipper since [[WhatDoesSheSeeInHim she believes he's not good enough for her]] and she can't stand seeing Ran suffering because of Shinichi - for all Sonoko knows he's enjoying himself while her best friend is having a bloody miserable time. She later mellows out on this.
* SingleWomanSeeksGoodMan: Despite her flirty tendencies, Sonoko is only interested in [[GentleGiant Makoto]]. An [[NiceGuy incredibly polite]], brave young man who [[RescueRomance rescued her from a serial killer.]]
* SpoiledBrat: Milder than other cases.
* SpoiledSweet: She's too flighty and childish to be TheOjou but doesn't flaunt her wealth around in an overly bitchy manner. In fact, she appreciates that Ran doesn't try to mooch off her.
%%* SweetTooth
* TomboyAndGirlyGirl: One may ''think'' she's Ran's girly girl and her older sister Ayako's tomboy but Ran thing 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!
* ViolentlyProtectiveGirlfriend: A more vocal example than most. Sonoko completely proclaims to Inspector Yamamura that Makoto isn't the murderer in a case, and continues to give him death glares when the idiot makes veiled comments that he belives Makoto to be the culprit.

[[folder:Yuusaku Kudo]]
->''Voiced by Creator/HideyukiTanaka (JP)''. Juan Zadala and Roberto Alexander (first Latin American Spanish dub), Jorge Lillo (third Latin American Spanish dub)

* SlapSlapKiss: With Yukiko, at their worst.
* SmartPeopleWearGlasses: He sports glasses and is sharper than his son.
* StrongFamilyResemblance: [[http://www.detectiveconanworld.com/wiki/File:Young_Yusaku.jpg Here is Yusaku in his 20's, sans-moustache and glasses.]] The similarities between Dad and Shinichi went off the freaking ''ceiling'' with that.
%%* TallDarkAndSnarky
