Imagine Breaker comes from A Certain Magical Index, which began as a light novel series in 2004 and received an anime adaptation in 2008. It is the mysterious power in protagonist Touma Kamijou's right hand that negates supernatural abilities, and the anime gives that negation a distinct shattering sound cue. Fans ripped clean versions of the effect for edits and soundboards because it works without context as a clear audio symbol for cancellation. It remains popular in anime edits where an unstoppable power needs to fail instantly.
