Neko Majin Z is a self parody manga by Akira Toiryama author of Dragon Ball/Z and Dr Slump. Neko Majin ran for 5 chapters in the Japanese version of the famous manga magazine shonen jump and is also available in book format. NMZ makes lots of fun of DBZ, with the main character Z the Neko Majin being not too far from Db’s hero Son Goku.
