TIE fighters first appeared in Star Wars in 1977, and their twin ion engines gave them one of the films' most recognisable sounds, alongside lightsabers and Chewbacca. The LEGO Star Wars video games, starting in 2005, reused that familiar flyby roar for their brick-built ships, mixing film audio with playful gameplay. Clips of the short engine burst later spread through soundboards and edits, where its instant association with a passing Imperial ship makes it useful even out of context for chases, memes and fan films.
