Son Goku (Saiyuki)

Son Goku (孫悟空 Son Gokū) is one of the main characters in Saiyuki. He is the cheerful "Monkey King" who uses a staff, known as the Nyoi-Bo, as his primary weapon. There is no explanation given in the anime as to the origin of Goku's weapon; in the manga, it is revealed that the Nyoi-bo was sealed in a canister in the temple, which he and Gojyo shattered whilst goofing off. He is the Seiten Taisei, the Great Sage Equaling Heaven, and whose true self and powers are released when his diadem is removed.
