Goku Black is the main antagonist of the Future Trunks arc in Dragon Ball Super, where he creates a blade of concentrated ki instead of using a physical sword. The short, punchy version of that summoning sound became popular in anime edits and soundboards because it captures the character's cold, godlike menace in under two seconds. Creators reuse it for power reveals, villain entrances and versus edits, keeping it in rotation long after the arc aired because the sharp energy tone reads instantly even without visuals.
