Ghidorah (ギドラ Gidora) is a three-headed dragon kaiju who is mentioned in the 2018 animated Godzilla film GODZILLA: City on the Edge of Battle, and goes on to appear in the film's sequel, GODZILLA: The Planet Eater. It is the fifth onscreen incarnation of King Ghidorah, and marks the character's first appearance in a film since 2001.
A monstrous entity that takes the form of a golden three-headed dragon and inhabits the void between dimensions, Ghidorah has used super gravity to consume countless worlds throughout the millennia. 100,000 years ago, Ghidorah destroyed the planet Exifcalus, while the surviving members of the native Exif race took to the stars to find new worlds and appease their God. With each new world the Exif found and converted to their faith, Ghidorah was fed a new planet. The Exif eventually made their way to Earth, where the native humans faced extinction at the hands of Godzilla. They cooperated with the fellow refugee alien race the Bilusaludo and the humans to try and defeat Godzilla, but were unsuccessful. Following a failed plan to relocate all three races to Tau Ceti e, they returned to try and reclaim the Earth. With the humanoids' latest methods failing to stop the now even larger and stronger Godzilla, the Exif archbishop Metphies and cardinal Endurph manipulated the desperate surviving refugees into praying for Ghidorah to come forth and eliminate Godzilla. Their manipulation succeeded and Ghidorah arrived in this dimension, promptly killing the majority of the surviving refugees before turning his wrath against Godzilla. Realizing that Ghidorah would destroy the Earth itself along with Godzilla, Captain Haruo Sakaki and his allies managed to sever Metphies' link to Ghidorah, allowing Godzilla to fight back and banish Ghidorah back to the dimension from whence he came.
