Goku (孫 悟空, Son Gokū) is a character in the Dragon Ball metaseries created by Akira Toriyama and is the main protagonist in the Dragon Ball universe. Goku means aware of emptiness (The 'Go' syllable means enlightenment, and the 'Ku' syllable means Sky or Emptiness). Goku's last name, Son, is derived from 'Sun' Wukong, which shows how the monkey-tailed boy is based from the famous Monkey-King from Journey to the West. At first, he is depicted as a direct parody of the character Sun Wukong, who appears as the main protagonist in the Chinese legend Journey to the West. Journey to the West tells the story of a monkey king named Sun Wukong, who searches for the seven dragon pearls which are guarded by a dragon in the West. Sun Wukong's noted possessions are a magical staff and a flying cloud, just like Goku has in the Dragon Ball series.
Sun Wukong and Goku.Akira Toriyama's "Dragon Ball" at first directly parodies this series, but quickly departs from it after the first saga. It then develops more into a martial arts series, instead of it heavily focusing on fantasy stories like in the beginning
