Droidekas were LEGO minifigures in the Star Wars LEGO theme. They were not made in the usual style of minifigures, but made of many different parts. These were used by the Trade Federation and the CIS to kill their strongest enemies, including Jedi knights. They were used since the creation of Battle Droids, however fewer in number, since each had the ability to activate a shield generator and shoot rapid-fire blasts. In addition to being able to deploy blaster shields and repeater blasters, droidekas were able to roll up into balls to move across the battlefield faster. Their shield generator could only be penetrated by slow moving objects, so blaster shots would be deflected.
