The ShodaiGhido (初代ギド?) is the ShodaiGidoKing Ghidorah suit design used in the 1964, 1965, 1968, and 1972 Godzilla films, Ghidorah, the Three-Headed Monster, Invasion of Astro-Monster, Destroy All Monsters, and Godzilla vs. Gigan, as well as the 1973 television series, Zone Fighter.
Originally, before production of Ghidorah, the Three-Headed Monster, this suit had purple scales and rainbow-colored detail on the wings, but later on, the entire body is recolored into a gold color. The heads of this suit has two curved horns on both sides with a crescent in the middle and a mane on each one, much like the appearance of a Chinese or Japanese Dragon. The actor is inside the middle head, and would hunch over, holding a pole, with the necks and heads being controlled by wires.
In Godzilla vs. Gigan, a stiff prop was used for scenes when King Ghidorah flew. This prop had red eyes and its wings and necks were fixed in place, giving King Ghidorah the bizzare appearance of hovering in the air.
- The ShodaiGhido was portrayed by a different suit actor in every one of the Godzilla films it appeared in.
- The ShodaiGhido the only King Ghidorah design that was used in more than one film.
