About
A green-haired, cherub-like creature with wings, hatched from an egg brought home by Senbei from a time traveling trip; later they inexplicably replicate into twins. Gatchan eats almost anything, except for rubber, and particularly likes to eat metal; they can also shoot rays from their antennae. Gatchan speaks in their own language consisting primarily of sounds like "pupipopipi" that Arale somehow seems to understand. In 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 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), God was about to destroy humanity. However, after seeing the life of Penguin village, he changed his mind and left the 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 they are known as "Gadzilla" in the English version. Gajira is occasionally mistranslated as "Gazira."
