A kaiju from Godzilla series, first appeared in its own standalone movie Ghidorah, the Three-Headed Monster (1964). Since its debut, King Ghidorah has the most theatrical appearance of any kaiju within the series bar Godzilla itself, thus it is often considered an arch-enemy of Godzilla.
King Ghidorah is a large, yellow, three-headed dragon with an ability to shoot lightning bolt from its mouth. It is typically depicted as an alien kaiju who brought devastation upon any planet it made a landfall.
In some depictions, each head of King Ghidorah has its own personality, which led to the characters within that media to name each of Ghidorah's head based on their behavior.
