— Gatchan

Gadzilla Norimaki (more commonly known as Gatchan for short) is one of the main characters of the Dr. Slump series. Gatchan's 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 two beings with them being referred to as Gatchan #1 and Gatchan #2 with both having no distinct differences.


Gatchan is a green-haired, cherub-like creature with wings. Although Gatchan has no defined gender, the manga constantly refers to it as her due to it not having genitals.


Gatchan's real name is a combination of the names of Gamera and Gojira, who is known as Godzilla in the West; hence she or he's known as "Gadzilla" in the English version.


Gatchan speaks in his/her own language consisting primarily of sounds like "pupipopipi" that Arale somehow seems to understand and it has been named Gatchanism by the manga. She or he eats almost anything, except for rubber as it was seen in "Gatchan Goes for a Walk", and she or he particularly likes to eat metal. She/he can also shoot rays from his or her antennae. She's like Arale in terms of interests and personality, being similarly innocent and playful, as well as the character who understands Arale the most. Gatchan is seen following Arale everywhere and playing with her almost all the time.

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, the Kami in Dr. Slump is a different deity from Kami the Guardian of Earth in Dragon Ball as the Kami of Dr. Slump oversees the entire Milky Way Galaxy, while the Kami of Earth in Dragon Ball is the pure-hearted mortal God that oversees the planet Earth) 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 his/her 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, he changed his mind and left the earth as it is.
