Iron Man is a Marvel superhero whose armoured suit became instantly recognisable after the 2008 film Iron Man, starring Robert Downey Jr. as Tony Stark. The suit's mechanical noises, from its assembly to its flight systems, became part of the character's identity across later Marvel films and games. Clips of those sounds later spread through soundboards, memes and short-form video, where they are reused as a quick cue for technology, power and transformation. The sound remains popular because it is immediately understood even without any picture of the hero.
