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