Gajira "Gatchan" Norimaki #1 & 2 are green-haired, cherub-like creatures.
Gatchan hatched from an egg brought home by Senbei Norimaki from a time traveling trip. Later on, it inexplicably replicates into a second one. Gatchan eats almost anything, except for rubber, and particularly likes to eat metal. She/He can also shoot rays from his/her antennae. Gatchan speaks in his/her own language consisting primarily of sounds like "Koo pee pee poo" that Arale Norimaki somehow seems to understand. However, in the manga, Gatchan has said a few words in Japanese/English. Being a baby, Gatchan also imitates what others do (most of the time, what Arale does). Gatchan does not physically age.
In Dr. Slump volume 17, it is revealed that Gatchan is actually an angel sent by God (or Kami if this story connects with Dragon Ball), to prevent further development of the human civilization. After seeing that other civilizations eventually destroyed themselves and the planets they lived on, God 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), God was about to destroy humanity. However, after seeing the life of Penguin Village, he changed his mind and left Earth as it is. Gatchan's real name is a combination of the names of Gamera and Gojira, who is known as Godzilla in the West; hence s/he is known as "Gadzilla" in the English version.
The Gatchans appear in the movie Dragon Ball: Mystical Adventure and during the General Blue Saga of Dragon Ball. In Mystical Adventure, they fire their Antenna Beam at General Tao, when the latter attacks Arale with his Dodon Ray.
