King Ghidorah (キングギドラ Kingu Gidora) is a three-headed dragon kaiju who appeared in the 1991 Godzilla film Godzilla vs. King Ghidorah.

The centerpiece of a scheme by time-traveling terrorists from the year 2204 to bring Japan to its knees in the past before it could become a corrupt economic superpower, King Ghidorah was the result of three genetically engineered pets called Dorats being left behind by the Futurians on Lagos Island in 1944. In 1954, the Dorats were exposed to the Castle Bravo.
