Wanting the series to have a Chinese appearance, Toriyama used the color of the robes worn by Buddhist monks for Goku's "dōgi". During the early chapters of the manga, Toriyama's editor, Kazuhiko Torishima, commented that Goku looked rather plain. Toriyama had given him simple clothes on purpose because it was a fighting manga, so to combat this he added several characters like Master Roshi and Krillin, and created the Tenkaichi Budōkai to focus the storyline on fighting. To defy the assumption that Goku would win the tournaments, Toriyama made him lose the first and second but win the third. Toriyama also mentioned Torishima wanted Goku to form a relationship with Bulma, but this was never applied to the series.
