, known in some major English adaptations as Jimmy Kudo, is a fictional character and the main protagonist of the manga series Case Closed, created by Gosho Aoyama. A high school detective, he is forced to ingest the lethal poison after an encounter with Gin and Vodka, agents of the mysterious Black Organization, while they were having a secret deal in an amusement park. Due to a rare side effect, the poison did not kill him. Instead, it shrinks his body into that of an elementary school-age child and forces him to adopt the pseudonym to hide from those who poisoned him. He lives with his childhood friend Ran Mouri and her father Kogoro Mouri as he awaits the day he can take down the Black Organization and regain his original size. Creation and conception The idea that Shinichi Kudo would be turned into a child stemmed from the idea of a Tortoiseshell cat Sherlock Holmes as a protagonist. Gosho Aoyama's idea was the cat would indicate the crucial evidence needed to solve the case; a performance the child-turned Shinichi does to help those around with the investigation. Shinichi was inspired by the fictional private eye Shunsaku Kudo. Aoyama revealed that his editor was against the name Conan due to the protagonist from the anime series Future Boy Conan sharing the same name and had suggested to name him Doyle instead. The author stuck with the name Conan believing it would overtake the Future Boy series. According to Aoyama, Shinichi's catch phrase, , was thought of by the anime adaptation's script writer and written into chapter 95 of the manga at the same time. In the English localizations, the catch phrase is translated as "One Truth Prevails". Appearances In Case Closed Shinichi appears at the beginning of the series as a gifted 16-year-old student at Teitan High School in Tokyo. He was already well known as a brilliant young detective who had closed many difficult cases that the professionals could not. He is also secretly in love with his childhood best friend Ran Mouri (Rachel Moore), but refuses to admit his feelings due to both stubbornness and shyness. Later while on a date with Ran to a theme park, Shinichi leaves Ran and follows two suspicious characters, Gin and Vodka, suspecting they are criminals. Gin ends up attacking Shinichi and forces him to drink an experimental poison APTX (Apotoxin) which
