Age: 6-7 (as Conan); 17 (as Shinichi) Height: Unknown (as Conan); 174 cm (as Shinichi) Weight: 18 kg (as Conan) Date of Birth: May 4 Relatives: Kudou Yuusaku (father) &amp; Kudou Yukiko (mother) Nicknames: Cool Kid (Jodie Starling), Cool Guy (Vermouth), Silver Bullet-kun (Vermouth), Glasses Kid (Sonoko Suzuki), Holmes' Apprentice (Apollo &amp; Minerva Glass)  At the beginning of the series, Kudou Shinichi is a 17-year-old student at Teitan High School. He is already well-known as a brilliant young detective, the "Savior of the police force," for solving many difficult cases that the professionals could not. However, while investigating two mysterious men, he is spotted and forced to swallow an experimental poison known as APTX 4869. This results in his body shrinking to that of a 6-year-old.  Shinichi comes up with the alias Conan Edogawa after Arthur Conan Doyle and Edogawa Rampo and pretends to be a distant relative of Agasa's who places Conan in Ran's care. Ran's father Mouri Kogorou, owns a Detective Agency which Conan uses to his advantage to discover cases involving the Black Organization.  As Conan, Shinichi helps Ran's father solve cases by putting him to sleep and simulating Kogorou's voice using the special bowtie gadget Professor Agasa made for him. By solving cases one after the other, he helps build up Kogorou's reputation who will later on be referred to as "Sleeping Kogorou." He also spends a good amount of time with his Detective Boys fellows and solves many small cases with them and sometimes in the company of Professor Agasa.  Conan remains very close to Ran, who in return is very protective of him. However, because Ran is unaware of his true identity, Conan often finds himself in awkward situations with her, such as when she confessed her feeling for Shinichi to him and when she made him bathe with her at a hot spring.  Conan's intelligence remains intact even though he has shrunken into a child. As Shinichi, his deductive ability earned him the monikers "Heisei Holmes" and "Savior of the Japanese police force." Conan maintains an extraordinarily broad knowledge of many subjects and trivia that help him solve cases and escape tricky situations. Conan tries to speak in a child-like manner when dealing with adults, but he often gets caught up in the current case and begins speaking like an adult, referring to advanced topics and using reasoning much too complex for a normal child. When this happens, he often tries to pass it off as "something [he] heard on TV" or "taught by uncle Kogoro/professor Agasa/Shinichi-niichan."   Likewise, he makes no effort to hide his love for Sherlock Holmes and soccer, so if he called out for talking about either subject in too much detail, he tries to escape suspicion by saying it was something Shinichi told him about. Although as the series has progressed the adults around him have become more used to his "being quite smart for a child," causing him to behave more like himself around them, he still tries to pass as a normal child. The only police officers with whom Conan can speak in a professional manner are the FBI, especially Jodie Starling, Shuichi Akai, James Black, and Inspector Kansuke Yamato of the Nagano Police, all of whom suspect that there is more to Conan than meets the eye.  Conan tends to act more like himself around the Detective Boys, even to the point that they find it odd when he acts like a child around adults. He will often play games like baseball with the Detective Boys, but he is too used to soccer to perform well and will even instinctively use soccer techniques, such as kicking in games that do not call for it. Because he is unfamiliar with popular games and TV shows, and bad at video games, Genta and the others tend to think of him as dumb. This annoys Conan so much that he will secretly watch TV in the living room after Kogoro and Ran go to sleep to get more "practice" in.  (Source: Detectiveconanworld.com)

Conan Edogawa

Is the grandson of Arsène Lupin. He is the world's most wanted thief. Often in his adventures, he takes it upon himself and his gang to foil other criminals engaged in more serious crimes. He sometimes appears incompetent, but mostly as a charade to catch his opponents off guard. While he has been arrested and thrown in jail on a number of occasions, he has always managed to break out. His infatuation with Fujiko Mine is perhaps his biggest weakness, as it often lands him in undesirable situations.

Arsene Lupin III

Mouri Ran is a childhood friend of Kudou Shinichi. She is the daughter of Mouri Kogorou, a private detective, and Kisaki Eri, a lawyer. Her parents got separated when she was seven, and one of her biggest goals is to get them back together. Her best friend next to Shinichi is her classmate Suzuki Sonoko, who constantly teases her about her relationship with Shinichi.  After Shinichi's disappearance, Ran met Edogawa Conan, who was introduced by Professor Agasa as a "distant relative" and asked Ran if she wouldn't mind taking care of him at her house. She and her father practically adopted him; Ran immediately came to think of him as a surrogate little brother. Little did (and still does) Ran know that "Conan" is actually Shinichi.   Ran's greatest personality trait is that she genuinely cares for those she loves. She is also patient, kind, and nurturing. Like Shinichi, she highly values justice to the point of idealism. 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. Ran is also very hot-blooded and tends to act on impulses when the people she cares about are involved; the combination of jumping to conclusions and not hesitating to use karate on those who she perceives to have wronged someone have led to several "near-miss" misunderstandings. Early on, she would become violently suspicious if she thought Shinichi was philandering although more recently his confessions have lead her to trust his intentions. Even though Ran is in love with Shinichi, she often fails to convey her feelings because she suddenly becomes self conscious.   She can be very brave and resourceful when she wants to be, and rescues Conan from trouble on occasion. However, she has an irrational fear of the supernatural and is thus - unlike her friend Sonoko - absolutely no fan of anything related to the horror genre. She also constantly tries to reunite her father and mother again - though with little success, thanks to the mutual stubbornness of both parents. Men also tend to pay her a lot of undue romantic attention, a fact that makes Sonoko somewhat jealous (and of which Ran herself is completely unaware).  Ran is very self sufficient for her age. This is because her father is drunk, slovenly, and fiscally irresponsible. She handles many of the Mouri household's financial affairs and all the cooking and housework. She also ensures Kogorou doesn't slack off on his job, is on his best behavior for client meetings, and she often greets and provides refreshments for potential clients.

Ran Mouri

Agasa Hiroshi is an inventor and Shinichi's closest neighbor, living in a large house right next to the Kudou residence. He makes his living with a wide number of patents and inventions, mostly video games (of whom the Detective Boys are enthusiastic test players). He has been a friend of Shinichi and Ran since their childhood years.   After Shinichi had been shrunk by the APTX 4869, the first person he met and entrusted himself to was Agasa. After having been convinced that the little boy was Shinichi, Agasa was also the first one to advise Shinichi to exercise caution in his pursuit of the Black Organization. He also helped Shinichi in establishing his new identity as Edogawa Conan, including constructing several gadgets which help Shinichi in carrying on his detective work surreptitiously, and in order to perfect Conan's cover, he also enlisted him into Teitan Elementary and thus came to know the children who would form the Detective Boys. When Miyano Shiho fled the clutches of the Black Organization, she fled to Shinichi's house but collapsed from exhaustion before Agasa's doorstep. Agasa subsequently took her in, learned about her true identity and helped her establish her new identity as Haibara Ai. He also entrusted Shinichi's parents with the secret about what has happened to their son.  Ever since these beginnings, Agasa has been an invaluable friend for Shinichi and the Detective Boys as a confidant, paternal friend, and someone to hang out with. He often takes the children on trips, most of which turn into criminal cases instead.   Agasa is a jovial and outgoing person and has many friends in his community, a fact which helped him in his covering up of Conan's and Haibara's true origins (he simply claims that they are the children of his friends and acquaintances).  Agasa has a special love for pasta and tomato juice.

Haibara Ai, real name Miyano Shiho, is the inventor of the APTX 4869 poison that shrunk Kudou Shinichi into Edogawa Conan, and a victim of the poison herself. Formerly Sherry of the Black Organization, she is on the run from them and lives with Professor Agasa. She is also one of few characters who knows Shinichi is Conan.   Miyano Shiho and her older sister, Miyano Akemi, were born into the secret crime syndicate "The Black Organization." Her English mother, Miyano Elena, and her Japanese father, Miyano Atsushi, were both scientists working for the Black Organization on an important secret project. While Haibara was young, both her parents died in what was claimed to be an accident. While Akemi lived a normal life, the highly intelligent Haibara was groomed to take over her parents' research. A child prodigy, she was sent to the United States for education at a very young age, and then later came back to Japan to finish her parents' secret project.  Shiho was unhappy that the Black Organization's was using the incomplete APTX 4869 for murder, as that was not the drug's intended purpose. When Shiho received word that her sister Akemi had been killed, but was given no explanation why, she decided to boycott her research until the Black Organization gave her an adequate explanation. Instead, the Organization confined her in a small room to await her execution. With no other way out, she took a pill of APTX 4869 to commit suicide, but instead shrank into an eight year old girl. In her new, smaller body, she escaped from the Black Organization and attempted to reach Shinichi's house, hoping he might be able to help her. Exhausted, she collapsed in front of Shinichi's house, where she was found by Professor Agasa, who took her in. In fact, as it turned out later, Agasa was acquaintances with her parents—especially her father—even though he didn't know at that time that they had children or were part of the Black Organization.  To prevent the knowledge of her transfiguration from being discovered, Shiho and Professor Agasa create her alias Haibara Ai. As Haibara, she attends Teitan Elementary School with Kudou Shinichi's shrunken form, Edogawa Conan. Following her first adventure with the Detective Boys in which they investigate the disappearance of a schoolmate's brother, she reveals her true identity to Conan and the fact that she had developed the APTX 4869. At first stunned, then outraged, Conan protests her presence, but as time passes, he accepts Haibara as a friend and fellow victim, though her cynicism and secretive air still rail him at times. Haibara also joins the ranks of the Detective Boys, and although she does not think too highly of her teammates' immature antics, she has come to value them all as close friends.  Haibara has a calm and cool personality, sarcastic wit, and high intelligence. When freshly escaped from the Black Organization, she was cynical and pushed others away. Haibara has since defrosted by embracing her new child life and has established strong relationships with Conan, the Detective Boys, Agasa, and Ran.  She tries to keep Conan from doing reckless things that may give away their identity, though often she is surprised by his actions which usually result in gaining the information he needs while also keeping their identities secret. However, whenever Conan is reckless in regards to keeping his identity from Ran, Haibara is the one who plans ahead in order to keep him from being revealed.
