Gamera

ガメラ

Gamera is a fictional monster, or kaiju, from a series of Japanese films. Making his debut in the 1965 movie Gamera, the Giant Monster, both the character and the initial film were designed to rival the success of Toho's Godzilla.
Gamera appears as a massive, flying, fire-breathing prehistoric turtle. In the first movie, he is shown as aggressive and destructive, although he also rescues a child. As the series continued, Gamera assumed a more benevolent role, evolving into a guardian of humanity—particularly children—as well as nature and the Earth, defending them against extraterrestrial races and other giant monsters.
