Neko Majin (ネコマジン) is a Japanese one-shot manga series written and illustrated by Akira Toriyama. Spanning eight total installments published irregularly between 1999 and 2005 in Shueisha's shōnen manga magazines Weekly Shōnen Jump and Monthly Shōnen Jump, they were collected into a single kanzenban volume in April 2005. Its later portion is named Neko Majin Z (ネコマジン Z), and is a self-parody of Toriyama's Dragon Ball. Source: Wikipedia (en)
