In Akira Toriyama's manga series Alare, there is a Nicholkin King whose mission is to conquer the universe, Nickkin is an uncompromising alien creature with a large face, a butt on his head, and tentacles on his ass.
Because their body structure is very unique, the tentacles on the side of the buttocks are also noses, so when they go to the toilet, they can only smell themselves, and they must put their heads upside down in the toilet to go to the toilet.
Through the official floor plan data, it can be further seen from their internal structure, Nickkin's feet are actually ears, heart underneath, the head is the large intestine and small intestine.
Of course, dominating the universe cannot be achieved alone, and King Nickkin also has an important partner who sometimes chats and plays together, sometimes quarrels, and works together on Earth to study how to dominate the universe.
In the Alare comics, King Nickkin returns to the planet Nickkin on a spaceship.
Incredibly, not only that, but there were a lot of "ass man" characters at once, the most famous being the ass star man in "Muscle Man", and the perverted masked Superman who put his pants on the top of his head.
Why did Japan at that time have such a boom ass man? In fact, it is still related to the general environment at that time, in the early 80s of Japan, the economy is still developing rapidly, based on this atmosphere, light and funny themes are very popular.
Whether it is "Alare", "Dragon Ball" in the early days of Goku, or other manga works, some funny characters will be added, but with the rapid decline of the Japanese economy, the audience is more inclined to rigorous and rich characters, so the pure appearance of funny characters has gradually faded out of people's vision.
