Soundwave is a Decepticon from Transformers: Dark of the Moon, the third live-action Transformers film released in 2011. In the film, his transformation is accompanied by the franchise's signature blend of clanking metal and electronic machinery, a sound designed to make the robots feel massive and mechanical. Fans later isolated this moment for soundboards, removing the surrounding dialogue so the transformation could be reused on its own. It remains popular because it instantly reads as a Transformers transformation, even without any visuals, and works for reveals, builds and villain entrances in edits.
