Megatron is the leader of the Decepticons in Transformers, the 2007 live-action film directed by Michael Bay that brought the long-running toy and cartoon franchise to modern cinema. In the film, his alternate mode is a Cybertronian jet, and his transformations were designed as complex, layered mechanical sequences rather than simple cartoon morphs. The sound quickly became familiar to fans through clips, edits and reaction videos shared online, where it now works as shorthand for a powerful machine changing form, even for viewers who have not watched the full film recently.
