Darth Vader first appeared in Star Wars in 1977, and his signature Imperial March was composed by John Williams for The Empire Strikes Back in 1980. The theme became one of cinema's most recognised villain motifs, and rock and metal covers later reworked its brass lines into guitar riffs for edits and fan videos. This version sits alongside other Vader clips shared by fans, including Darth Vader NOOOOOOOOO!, and stays popular because the melody instantly signals power, danger and parody in just a few seconds.
