Mothra is Toho's giant moth kaiju, first appearing in Mothra (1961) and returning in the Heisei era with Godzilla vs. Mothra in 1992, alongside the Rebirth of Mothra trilogy later in the decade. Her signature screech, a piercing chittering cry, became one of the most recognisable monster sounds in the franchise. Clips of the roar circulate on soundboards and in fan edits, where it marks her entrance or answers Godzilla's own roar in versus videos. It endures because Mothra remains the franchise's most beloved guardian monster.
