Thunderbolt is a long-running Electric-type move in the Pokemon video games, most famously used by Pikachu and other Electric Pokemon, and its distinctive crackling zap has become one of the series most recognisable battle sounds. As Pokemon gameplay, fan animations and short-form edits spread online, the short clip began appearing outside battles as a shorthand for a sudden shock or burst of energy. It remains popular because it is instantly recognisable to fans, lasts only a few seconds, and works just as well in a joke edit as in a serious battle montage.
