Mothra first appeared in Toho's 1961 film Mothra and soon became one of the most recognisable kaiju in the Godzilla franchise, returning in films such as Mothra vs. Godzilla and later Hollywood entries including Godzilla: King of the Monsters in 2019. Unlike many monsters, she is usually portrayed as a benevolent guardian, often accompanied by twin fairies and a distinctive musical motif. Her roar has been reused across decades of films, games and fan edits, which is why it remains instantly recognisable to kaiju fans and a popular choice for dramatic, larger-than-life moments online.
