Sha Wujing
The plot and characters of "Dragon Ball" were loosely modeled on the classic Chinese novel "Journey to the West", with Goku being Sun Wukong ("Son Goku" in Japanese), Bulma as Tang Sanzang, Oolong as Zhu Bajie, and Yamcha being Sha Wujing. Toriyama wanted to create a story with the basic theme of "Journey to the West", but with "a little kung fu" by combining the novel with elements from the kung fu films of Jackie Chan and Bruce Lee. Torishima said he chose the novel largely because it was a free intellectual property, but also because its Chinese setting was not common in manga at the time and would make it both unique and differentiate it from "Dr. Slump"s US West Coast feel.
