This sound is tied to Vergil from the Devil May Cry games, where Devil Trigger is his demonic power-up form. Short clips of his grunts and transformation audio became popular in action edits, especially in anime and gaming communities on short-form video platforms. It stays useful because the cue is instantly readable even to viewers who do not know the series: a character is powering up, locking in or turning dangerous. That clear meaning keeps it in circulation for edit culture and reaction-style meme videos.
