Battle droids are the robotic soldiers of the Separatist army in Star Wars, first seen in large numbers in The Phantom Menace, and later as a regular presence in The Clone Wars series. Their stiff movements, distinctive voices and repeated Roger Roger catchphrase made them fan favourites despite being comic villains, and their blaster fire became a shorthand sound for clumsy sci-fi combat. Clips of that fire spread through soundboards and short-form edits, where creators reuse it to parody battles or add instant Star Wars flavour without needing dialogue.
