Neko Majin

Originally a one-shot bearing little relation to Akira Toriyama's other series, the first chapter of Neko Majin appeared in Weekly Shonen Jump in April 1999 (WJ #22-23). Though there were some similarities, it didn't become a self-parody of the Dragon Ball manga until "Neko Majin Z", which had cameos of characters from the author's magnum opus. As of 2005, the series was completed with eight total chapters (five of which are Dragon Ball parodies). These chapters were compiled into a "kanzenban"-style package for release in Japan on 4 April 2005.

The series revolves around the adventures of various characters from the "Neko Majin" race, a group of cats that can use a little bit of magic, but seem to enjoy practical jokes and martial arts even more. It eventually spins off into "Neko Majin Z", centralizing around "Z", a cat-like version of Son Goku complete with nyoi-bo and typically Dragon Ball Z-style attacks, such as the "Nekohameha", an attack that the Neko Majin from Neko Majin, "Neko Majin", also used. Other familiar motifs show up during the course of the series, including Frieza's son Kuriza, a fat Super Saiyan named Onio (following the Saiyans' vegetable pun trend, this one is an obvious pun in onion), and even cameos by actual Dragon Ball characters Vegeta, Majin Buu, and Goku and his family.

This is a manga series written by Akira Toriyama- if you like dbz you should read this!
