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, Rodan and Mothra.
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.
After defeating King Ghidorah and sending it to the depths of the sea, Godzilla began to wreck havoc throughout Japan. Emmy Kano, a Futurian who rebelled against her crew, and M11, her android, were asked if King Ghidorah could be revived in the 23rd century. If possible, he could be brought back to the present and used as an anti-Godzilla weapon to protect Japan. Emmy and M11 agreed and went to the future using the time machine KIDS.
As Godzilla continued his rampage through the center of Tokyo, King Ghidorah, now Mecha-King Ghidorah, materialized in a flash of pulsing energy. Piloted by Emmy and reinforced with several robotic segments, Mecha-King Ghidorah was more powerful than before. Mecha-King Ghidorah fired his gravity beams and triple laser beam at Godzilla, sending him crashing toward some buildings. Godzilla managed to regain his balance and damage both of Mecha-King Ghidorah's wings. Emmy then fired Mecha-King Ghidorah's energy-conducting capture cables and released its machine hand restraint. Mecha-King Ghidorah lifted Godzilla into the sky and over the sea, but both were sent crashing into the waves when Godzilla fired his atomic breath at it. Emmy quickly escaped in KIDS, leaving both monsters trapped on the ocean floor.
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.
