In the Showa series, King Ghidorah is an alien dragon said to have attacked Venus under his own power many thousands of years ago, wiping out the planet's entire civilization. He later attacked Earth, but was repelled by Earth's monsters (Godzilla (Showa), Rodan (Showa) and Mothra (Godzilla)
In Godzilla vs. King Ghidorah, King Ghidorah is part of a scheme by time-traveling terrorists known as the Futurians to destroy Japan in the past to prevent it from becoming a global economic superpower. He is the result of the Futurians placing three genetically-engineered creatures from the future called Dorats on Lagos Island in the year 1944. In 1954, the Dorats were exposed to the Castle Bravo hydrogen bomb test conducted at nearby Bikini Atoll, which caused them to merge and mutate into King Ghidorah.
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.
