King Ghidorah is one of Toho's most famous kaiju, first appearing in the 1964 film Ghidorah, the Three-Headed Monster. Across multiple Godzilla movies, the character's roar became part of the series' recognizable sound design. Online, the clip is commonly reused in kaiju fan edits, crossover videos and power-scaling memes because it instantly signals a massive, world-ending threat. It remains popular with monster fans thanks to Ghidorah's status as one of Godzilla's signature rivals and one of cinema's best-known giant creature villains.
