Battle Droids have many names in the infamous Star Wars saga including clankers, combat droids, droids and battle bots. They go through many changes throughout the movies, first used in The Clone Wars. They are quirky looking things that can do a lot of damage. Generally carrying a gun of sorts, the Battle Droids were outlawed after the Clone Wars, but reclassified as Security Droids as a loophole to still be used. There is a lot of history behind these powerful machines!
