The series revolves around the adventures of the Neko Majin, a race of cat-creatures who enjoy practical jokes and martial arts. At least two use Dragon Ball-style attacks such as the "Nekohameha", while one in particular, named "Z", wears an outfit like Dragon Ball's Son Goku, and carries a nyoi-bo. As the series transitions to Neko Majin Z, it becomes increasingly intertwined with the Dragon Ball world as regular characters join the cast, including an overweight Saiyan named Onio, and Frieza's son Kuriza. There are also guest appearances by Vegeta, Majin Buu, Son Goku and his family members.
