Mega Man 2 was released by Capcom for the Nintendo Entertainment System in 1988 in Japan and 1989 internationally, becoming the best-selling entry in the original series. The teleport effect was carried over from the first Mega Man game, used whenever the hero warps to a boss stage at the start of a level. As retro gaming, speedruns and emulation grew online, the brief beam sound was ripped and reused as a universal spawn and entrance cue far beyond the game itself.
