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 . Similarities between the two include their mischievous nature and possession of the and (which, in Japanese, have the same name as the source material).
Akira Toriyama's original design of Goku
When Toriyama started his first draft of Dragon Ball, he originally planned on making Goku full to make the series more faithful to 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. Toriyama's third draft became the final design.
Goku's full name is also based on Sun Wukong. The name "Son Goku" is simply the Japanese on'yomi rendering of Sun Wukong, as Chinese and Japanese share the same characters but with different pronunciations. "Sun/Son" is a common Chinese surname that normally means "grandchild", while "Wukong/Goku" is a common Buddhist name that means "perceiving air/awakened to emptiness". Reading "Sun Wukong" via the first and final characters only through the Japanese kun'yomi rendering system makes it read out as "Mago Gosora", used at some point as a gag in the original manga's run by the .

While Goku is an overall good person, designed him as one who fights mostly for personal joy of challenging strong opponents. To which, Toriyama notes that the anime tends to go overboard in making Goku look heroic, and that his original depiction of Goku in the manga has certain "poisonous" traits.

Goku's Super Saiyan form was heavily influenced by the martial artist Bruce Lee. According to Toriyama, Goku's piercing eyes were based on Lee's paralyzing glare. Dragon Ball Z anime character designer Tadayoshi Yamamuro also used Lee as a reference for Goku's Super Saiyan form, stating that, when he "first becomes a Super Saiyan, his slanting pose with that scowling look in his eyes is all Bruce Lee."
