Shinichi Kudo, a high school detective transformed into a six or seven-year-old after being poisoned with the experimental drug APTX 4869 by the Black Organization, adopts the alias Conan Edogawa. This metamorphosis followed his attack at Tropical Land where he witnessed a suspicious transaction. To safeguard his identity and protect loved ones like childhood friend Ran Mouri, he becomes "Conan Edogawa" – a name blending Arthur Conan Doyle and Edogawa Rampo – and moves in with Ran and her father, Kogoro Mouri, posing as a distant relative of Professor Hiroshi Agasa. Professor Agasa, Shinichi’s neighbor and confidant, is the sole adult initially privy to Conan’s secret, supplying him with specialized gadgets to aid investigations while masking his true capabilities.
Though physically a child, Conan retains his teenage intellect, memories, and deductive prowess. He enrolls at Teitan Elementary School to uphold his cover, joining the Detective Boys: classmates Ayumi Yoshida, Mitsuhiko Tsuburaya, Genta Kojima, and later Ai Haibara, another APTX 4869 victim. Interacting with the group, Conan balances childlike behavior with subtly guiding their inquiries. He often feigns innocence with exclamations like "Ah-le-le?" to highlight clues, attributing advanced deductions to television, Kogoro, Agasa, or "Shinichi-niichan."
For discreet case-solving, Conan deploys Agasa’s inventions: a tranquilizer dart watch to sedate Kogoro and a bowtie voice changer to impersonate him, dubbing the incapacitated Kogoro "Sleeping Kogoro." This tactic elevates Kogoro’s detective reputation, granting Conan access to police investigations and potential leads on the Black Organization. When Kogoro is unavailable, Conan sometimes uses proxies like Sonoko Suzuki. Gadgets like power-enhancing kick shoes, solar-powered skateboards, and detective badge communicators/trackers offset his physical limitations, enabling actions like subduing criminals with precise soccer ball kicks.
Conan’s core objectives are dismantling the Black Organization, developing a permanent APTX 4869 antidote, and protecting loved ones – especially Ran, who remains unaware of his identity. This secrecy sparks recurring conflicts, such as Ran confessing her feelings for Shinichi to Conan or during intimate moments like shared baths. His dual existence strains his bond with Ran, who occasionally suspects a link between Conan and Shinichi but is consistently misdirected.
Conan confronts high-ranking Black Organization members across major arcs. In the Vermouth Arc, he exposes Sharon Vineyard as the disguised Vermouth, who later spares him due to Ran’s compassion. The Kir Arc reveals his alliance with FBI/CIA agent Hidemi Hondou (codenamed Kir), an Organization infiltrator. During the Bourbon Arc, he deduces Bourbon’s true identity as PSB officer Rei Furuya, forging collaboration post-misunderstandings. In the ongoing Rum Arc, he investigates the Organization’s second-in-command, Rum, identifying sushi chef Wakita Kanenori as a prime suspect based on Haibara’s vague descriptions.
Conan’s network extends beyond the Detective Boys to allies like Osaka detective Heiji Hattori (who deduces his identity), Agasa, Haibara, and law enforcement figures including Inspector Megure, Detective Miwako Sato, and Officer Wataru Takagi. He exchanges contacts with officers Takagi, Chiba, and Yumi Miyamoto, leveraging these connections for case resources while minimizing exposure. His international reach includes FBI collaborations with agents Jodie Starling and Shuichi Akai.
Key traits encompass photographic memory, soccer proficiency adapted to his child physique, lip-reading skill, and tone-deafness inherited from his original form. He favors iced coffee and curry, often juggling a soccer ball while deep in thought. His matching blood type with Ran reinforces their bond. Characters like Heiji, Haibara, and Inspector Megure note Conan’s frequent correlation with encountering criminal cases, jokingly questioning if he attracts incidents.
In non-canonical stories like OVAs and films, Conan’s characteristics persist. *OVA 7: A Challenge from Agasa! Agasa vs. Conan and the Detective Boys* sees him solving a staged kidnapping orchestrated by Professor Agasa, showcasing his deduction skills, gadget use like the detective badge, and Agasa’s severe nearsightedness without glasses.
Conan’s journey underscores his unwavering commitment to justice, strategic evolution against the Black Organization, and enduring emotional turmoil from his concealed identity. His capacity to forge alliances while guarding his secret remains pivotal to reclaiming his original life.
