Mega Man X was released by Capcom for the Super Nintendo in 1993, introducing X, a new hero who could charge his X-Buster for a stronger shot by holding the fire button. That rising charge sound became tied to the game's fast, precise action and to the satisfying moment before a fully charged blast. As retro gaming clips, speedruns and soundboards spread online, the effect moved beyond gameplay into memes and edits. It remains popular because it is short, instantly recognisable and signals power building toward a release.
