; :A race of magical cat-creatures, who span a variety of breeds and body-shapes, although most appear to have distinctive long ears in the manner of the author's
Cornish Rex. This series concerns three: a mixed-breed referred to only as "Neko Majin Mix"; , a male ; and , a disciple of Son Goku from
Dragon Ball. Mix and Z are both blue, while Mike sports calico fur; all three are of a similar, round body shape, and are drawn with angled slits for eyes. These Neko Majin possess abilities similar to
Dragon Ball characters, such as flight and the "Nekohameha",, similar to the Kamehameha. They are also capable of using some magic, such as the transformation abilities demonstrated by Neko Majin Mike. The source of these abilities appears to be a ball called a Majin Orb (majin-dama), without which they lose all powers. A common trait seems to be conning visitors with various services. Mix charges 100 yen in exchange for any favor, and Z in particular dresses as a koala and charges eight dollars to take pictures with them. He has a Super Saiyan-like transformation called Super Neko Majin. ; :A boy that Neko Majin Mike met about 30 years ago. He was a scrawny kid, but has since grown up to become a chubby teacher at a small local school. ; :A Saiyan with the overall body-shape and facial structure as
Suppaman,
Parzan, and
Bubibinman from Toriyama's manga
Dr. Slump. He first appears on Earth on honeymoon and desires to conquer the Earth and wipe out its inhabitants in order to make it a vacation home. He and his wife take a photo with the "koala" Z, but when the Neko Majin fondles his wife's breasts, he becomes enraged and transforms into a Super Saiyan. However, he is quickly defeated. He returns with Kuriza for further encounters with Z. ; :A nationally renowned fighter who is challenged by Neko Majin Z. He, too, has a girlfriend that he calls "Honey". In his fight with Z, he realizes that he is no match, and tries to get out of the battle except that Honey eggs Z on. ; :The son of
Dragon Ball villain,
Freeza; he resembles his father except that his head is in the shape of a chestnut. He is called by Onio to destroy Z, but runs out of pages for the fight. He later plays soccer with the gang. He frequently mentions that Neko Majin is wasting pages with meaningless comments and battle scenes. ;
Vegeta :Vegeta is called to Earth by Kuriza and Onio, who need help to defeat Z. Vegeta discovers that the Neko Majin is surprisingly strong, but receives an "urgent call" that requires him to leave to another planet, despite Kuriza mentioning that his cell phone should not have signal. He vows that he will never appear in another gag manga. ;
Majin Boo :Majin Boo makes a short appearance to help when Neko Majin Z is rendered helpless by Usa Majin (the lesser-known rabbit version of Neko Majin). Every time Z was not in the scene, Boo would appear, making people think he was the Neko Majin. ;
Son Goku :Son Goku makes an appearance in the last chapter of
Neko Majin Z where he spars with Z. He then tells the Neko Majin there is a new evil that he needs help to defeat at his family home. When they get there, Z learns that it is just a mouse in the pantry. ==Production==
