Mamagon is the mother of the monster family, who does all the motherly chores, such as cleaning and cooking for her misfit family of Chibira, Papagon and Getdata. A bit of an airhead, she usually is the one who tries to stop Papagon's inventions from going out of control or solve family problems with other Kaiju such as Agira or Alien Zarab.
- Mamagon's name would later be borrowed for the 1972 film, Godzilla vs Gigan by Toho Studios, where a manga artist had to come up with two new monsters based on what kids found scary. One, the homework monster, Shukra, and the other was Mamagon, a strict mother.
