The thermonuclear pulse comes from Godzilla: King of the Monsters (2019), the climax where a nuclear blast revives Godzilla and pushes him into his burning form. Overloaded with radiation, he emits three expanding pulses of atomic energy that vaporize everything around him, including King Ghidorah. The layered blast became a favorite on meme and movie soundboards for its sheer scale, often compared to a bass drop for the way its sub-bass seems to detonate the room. It endures because few effects sell unstoppable, world-ending force so instantly.
