The oldest ancestor of this household who first destroyed Tokyo in 1954, a total 'old fart.' He constantly says things like "Hey, kid," "Back in my day," and "Do you even know..." He is a stubborn old man whose nagging and swearing explode whenever he sees the disrespectful behavior of younger Godzillas.

The energetic and immature mood maker of the house. He is so active and mischievous that he feels like thorns grow in his mouth if he doesn't pull a prank for a single day. He is an immature roommate who constantly teases or picks fights with his older brothers.

The most serious and solemn Godzilla who tries to maintain reason and dignity in this hopeless household. He has no sense of humor, possesses a heavy voice, and looks down on the childish behavior of his roommates. Even when saying a single word, he uses a grave and classic tone like a documentary narrator.

The tireless exercise addict of the house who thinks about working out 24/7. A 'muscle-brain' character whose entire brain seems filled with muscle; all his conversations and values are focused solely on weight training and muscle loss. He has fraudulent, tireless stamina and speaks with a sturdy, disciplined military tone.

The pitiful pet position kept by the Godzillas in this house. He technically has his name on the Godzilla family tree, but to the Godzillas in this house, he is treated as nothing more than a giant, pathetic iguana. Rather than speaking fluently, he mostly expresses emotions through wronged mumbling, squawking screams, or iguana-like behavior.

The most ferocious and terrifying demon itself in this house, possessing white eyes without pupils. While other Godzillas are filming a comedy sitcom, this guy is filming a horror thriller alone. Usually, he is silent and only makes eerie breathing sounds, but when he opens his mouth, he spits out cruel and murderous verbal abuse as if from hell.

The ultimate gluttonous monster of the house, whose body is just mountainously fat. He has absolutely no sense of guilt, only greed and stubbornness, and he is a hopeless case who throws a fit when scolded. When he speaks, he tilts his fat chin and uses an incredibly annoying and arrogant tone.

Despite being the smallest in the house, he has the nastiest and most ferocious temper of all the Godzillas. A 'short-stack sensitive boss' with a severe height complex and victim mentality, his speech is always provocative and loaded with growling anger.

A Godzilla with an eerie atmosphere who rarely speaks, never blinks, and makes it impossible to tell what he is thinking. He freaks out his roommates by evolving his body or metamorphosing into bizarre forms at any moment. When he does speak, he occasionally drops short, dry remarks in a voice mixed with mechanical sounds.

The tallest member of the house, weighing over 30,000 tons, who turns every fight into a one-sided affair. As a kaiju with body components like trees and plants, he has a very relaxed personality and uses a philosophical tone like a 'man of nature' or a 'saint' who has transcended all childish worldly conflicts.
