Megalon (メガロ, Megaro) is a fictional kaiju (giant monster) featured in the 1973 Japanese tokusatsu film Godzilla vs. Megalon, the thirteenth Godzilla film produced by Toho. A beetle-like arthropod, Megalon is the primary antagonist of the film. Godzilla vs. Megalon is one of the most unpopular and frequently criticised of Godzilla films, and Megalon itself plays no small part in that (see below). Despite this, the character has remained a fixture of the popular imagination.
