The Imperial March, also known as Darth Vader's Theme, is a musical masterpiece composed by John Williams for 'The Empire Strikes Back' in 1980. In internet culture, the theme is used as a shorthand for someone making a grand, imposing, or unnecessarily dramatic entrance. Meme variations often include the caption 'Imperial March Intensifies' overlaid on images of people, animals, or characters walking with authority. It serves as the ultimate auditory cue for power, intimidation, or the arrival of a 'villainous' figure in everyday mundane situations, like a cat walking into a room or a boss entering an office.
