The name 孫 そん 悟 ご 空 くう is simply the Japanese on'yomi rendering of 孫悟空, as Chinese and Japanese share the same characters but with different pronunciations. Goku's adoptive full name is also based on the traditional Mandarin Chinese full name 孫悟空. Toriyama's third draft became the final design. During Toriyama's second draft, Goku was instead a full human dressed in sailor clothes that rode a flight mecha instead of the Flying Nimbus. When Toriyama started his first draft of Dragon Ball, he originally planned on making Goku full monkey to make the series more faithful to Journey to the West.
Similarities between the two include their mischievous nature and possession of the Power Pole and Flying Nimbus. The Dragon Ball universe began as a loose adaptation of the classic Chinese novel Journey to the West, with Goku himself as an alternate take on Sun Wukong. The original inspirations for that story were Hong Kong martial arts films, including Bruce Lee films such as Enter the Dragon (1973) and Jackie Chan films such as Drunken Master (1978) Toriyama later said he had a young Jackie Chan in mind for a live-action Goku, stating that 'nobody could play Goku but him.' The original incarnation of Goku in the Dragon Ball prototype Dragon Boy was Tangtong.
