This is a short 3.6-second clip built around Mecha King Ghidorah, the mechanical three-headed kaiju, with a metallic roar that fills the few seconds it lasts. It feels huge, menacing and deliberately over the top, like a villain arriving with no intention of being subtle, and it works best when you want a moment to feel instantly bigger and more threatening.
