Megalon is a beetle-like kaiju from Toho's Godzilla series, first appearing in Godzilla vs. Megalon in 1973. Created as an underground monster with drill-like arms, he became a cult favourite among kaiju fans despite appearing in only a small number of films. His distinctive roar has since circulated in monster compilations, fan edits and soundboards, where it stands in for generic giant-monster menace. It remains popular because it is instantly recognisable to Godzilla fans yet short enough to drop into almost any dramatic edit.
