Dr Slump Wiki

— Gatchan

Gadzilla Norimaki (則巻ガジラ Norimaki Gajira) more commonly known as Gatchan is one of the main characters of the Dr. Slump series. Gatchan is a cherub that was adopted into the Norimaki family after hatching from an egg and often follows Arale Norimaki around. Later in the series, Gatchan splits into a pair of identical twins from a chrysalis, with them now being referred to as Gatchan #1 and Gatchan #2.


Gatchan is a green-haired, cherub-like creature with wings. They have a small body similar to a baby, along with two antennae on their head. They lack any genitals. Although Gatchan has no defined gender, the manga and anime refers to them as both he and she.


Gatchan's full name is a combination of the names of Gamera and Gojira, who is known as Godzilla in the West. Arale came up with the name, likely out of her love of monsters.


Gatchan speaks in their own language consisting primarily of gibberish sounds that Arale somehow seems to understand and it has been named Gatchanism in the manga. They have a large appetite that makes them eat almost anything, except for rubber as seen in Gatchan Goes for a Walk. They particularly like to eat metal. They can also shoot rays from their antennae, mostly used as a retaliation mechanism. They are like Arale in terms of interests and personality, being similarly innocent and playful, as well as the character who understands Arale the most. Gatchan follows Arale often and plays with her almost all the time.

The Birth of Arale[]

Gatchan born

Gatchan is born!

Gatchan is born at the end of The Mysterious Egg when they hatch fully clothed from an egg that Senbei Norimaki brought back from the prehistoric ages, thinking a dinosaur was going to hatch from it.


Gatchan's wings were discovered during the bath.

In Is It a Girl? Is It a Boy!?, Gatchan is adopted into the Norimaki family and their name is given by Arale Norimaki. Arale finds out that Gatchan can eat everything, and that they can survive to fall from a very high height. While in the bath, it is shown that Gatchan has wings and no genitals.

Due to the anime having Gatchan's birth happen much earlier, Gatchan is present during the adaptations of chapters that they originally weren't part of because in the manga they happened before their birth.

In The Mysterious Dr. Monster?!, Gatchan is seen at the beginning of the episode sleeping on top of Senbei's head.

In My Friend, Mr. Bear!!, Gatchan accompanies Arale on the night she frees Mr. Bear out of the cage. Gatchan is present when Senbei and Arale train the bear before going back into the wild but was shot by the Hunter. Then Senbei transforms Mr. Bear into a cyborg using the machinery from Arale's body.

In Arale is Akane!?, Gatchan is part of Arale and Akane Kimidori's war game they have around the house dressed as a ninja. When Arale and Akane switch appearances, Gatchan remains at the Norimaki house with Akane.

Arale takes a picture of Gatchan when she walks home disappointed that she won't grow up (while the picture isn't shown on screen), Arale says that at least Gatchan will grow up. An elder version of Gatchan is shown at the end when Arale takes a picture of the TV showing the beginning of the episode.

God Gets Even![]

Main article: Volume 17: God Gets Even!
In Volume 17, it is revealed that Gatchan is actually an angel sent by the lord of the galaxy, Kami (despite their shared name, Kami in Dr. Slump is a different god from Kami, the Guardian of Earth in Dragon Ball) to prevent further development of the human civilization. After seeing that other civilizations eventually destroyed themselves and the planets they lived on, Kami placed an angel's egg on Earth. Gatchan's ability to replicate as well as their fondness of metal should have ensured that humanity would remain primitive and innocent. Seeing that Gatchan failed in the mission (due to Senbei's time-traveling intervention), Kami was about to destroy humanity. However, after seeing the life of Penguin Village and how happy Gatchan was with their family, he changed his mind and leave the Earth as it is.


Future Gatchans

In the future, Gatchan again multiplied several times until they were eight total (and most likely will continue to multiply).
