King Ghidorah

King Ghidorah (Japanese: キングギドラ, Hepburn: Kingu Gidora) is a giant dragon-like extraterrestrial monster, or kaiju, in Toho’s Godzilla media franchise. It first appeared in the 1964 film Ghidorah, the Three-Headed Monster, directed by Ishirō Honda. The character was initially created by Tomoyuki Tanaka, Eiji Tsuburaya, and Shinichi Sekizawa as an homage to the eight-headed mythological Japanese dragon Yamata no Orochi. Although the name of the character is officially trademarked by Toho as "King Ghidorah", the character was originally referred to as Ghidorah, Ghidrah, or Monster Zero in some English markets.

Although King Ghidorah's design has remained largely consistent throughout its appearances (an armless, bipedal, golden and yellowish-scaled dragon with three heads, two fan-shaped wings, and two tails), its origin story has varied from being an extraterrestrial planet-destroying dragon, a genetically engineered monster from the future, a guardian monster of ancient Japan, or a god from another dimension. The character is usually portrayed as the archenemy of Godzilla and a foe of Mothra, though it has had one appearance as an ally of the latter.

Despite rumors that Ghidorah was meant to represent the threat posed by China, which had at the time of the character's creation just developed nuclear weapons, director Ishirō Honda denied the connection and stated that Ghidorah was simply a modern take on the dragon Yamata no Orochi.
