Gyottos

Gyottos is a strange monster who first appears in the 1955 Godzilla Manga, Rampage Godzilla.

Appearance
Gyottos is a bizarre creature which doesn't resemble any Kaiju that appeared before it, and appears to only share common characteristics with his friends. He is a quadrupedal, turtle-like creature with a 'mane' of frills around his neck, and his forehead is covered in spots. He has dark, beady eyes, and three nostrils.

Rampage Godzilla
Godzilla wanted to become stronger, so he sought out the help of a group of monsters, Gyottos being among them. Gyottos is the second monster Godzilla meets, and the two have a sparring match.
