In Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack, King Ghidorah is reinvented as a heroic monster for the first, and so far only, time. In this film, King Ghidorah is the God of the sky and one of the three guardian monsters, along with Mothra and Baragon. An ancient Yamata no Orochi, an eight-headed dragon from Japanese mythology, King Ghidorah was slain by Japanese warriors thousands of years ago and laid to rest underneath Mount Fuji. The warriors prayed for King Ghidorah's soul, and over the next several centuries he slowly regenerated, empowered by the souls of Japan's honorable dead. However, he was awakened before he could grow back all eight of his heads, instead growing only three.
