Aurora Beam is an Ice-type attack from Pokémon, a move that fires a rainbow-coloured beam of light and has appeared across the video games and animated series. The sound itself captures that idea in miniature, a bright, icy rush that players associate with early Pokémon battles and magical attacks. As clips from the games spread through fan edits, reaction videos and soundboards, it became a handy shorthand for anything sparkling, freezing or suddenly powerful. It endures because it is instantly recognisable, short enough to drop into almost any edit, and evocative without needing any dialogue.
