Zettaflare gained massive internet fame following the release of Kingdom Hearts III, where Donald Duck unexpectedly casts the legendary spell—a feat previously reserved for the most powerful dragons in the Final Fantasy franchise. The moment shocked fans because the prefix 'Zetta' implies a power scale quintillions of times stronger than 'Mega' or 'Giga' flares. In meme culture, Zettaflare is used to depict an extreme, nuclear-level overreaction to a minor problem or the unleashing of hidden, overwhelming power. It serves as the ultimate 'delete button' in digital arguments and gaming community humor.
