Wannya is a character from the anime UFO Baby who is also known as Baumiao.


This creature looks like a cat that walks on two legs and could talk so he is highly sapient. He has two ears, two round big eyes, a barely there nose, “w” shaped lips, two hands, two feet and a medium sized tail. He is mostly color white with some dash of brown on his left ear, left foot and some parts of his tail. He has 4 long whiskers—2 on the right and 2 on the left. Lastly, he wears no visible clothes but he has tuxedo life vest with a red tie.



Wannya and Ruu

Wannya and Ruu, the baby he is taking care of, are from the planet Otto which is 12 billion light years away from Earth—this indicates that it is most likely along the leading edge of speculated galaxies ZB-BO45326, BDF-521, A1703 zD6, BDF-3299, GN-108036, or SXDF-NB1006-2. One day while they are outside their home, they come across a wormhole, a black colored gateway to another realm. They get sucked inside it and they travel through spacetime through Ruu’s spaceship. They land in a temple where Kanata and Miyu are staying. Unfortunately, because of the impact when they landed, the navigation system gets damaged so they could not travel back to their planet. However, Wannya is assured that they are going to be rescued because the ship’s SOS beacon is active but with their planet’s technology, it could take a couple of years before they return.



Wannya as a fish

Wannya calls himself a “sitter-pet.” It is similar to a babysitter on Earth but the only difference is that he is a pet that takes care of a baby. He also states that they are highly capable with certificates. He writes daily on his sitter diary where he accounts all the happenings that they him and Ruu are experiencing.

Although he can walk on the ground, he can also fly using his tail as the propeller because in his planet of origin, most of them just fly around. Another one of his capabilities is to transform himself to different things. He could transform himself into human figures but his usual forms are a blond man and red-haired woman. Also, he could change into animals like a penguin or a gigantic fish or even into objects. As he is an alien, he is very particular when it comes to things, especially his shampoo. Once he uses a different kind of shampoo not from Planet Otto, he transforms involuntarily into different forms—human, animals and objects.


  • His favorite food on Earth is dumplings.
