In episode 1, I was shocked to see the Destroyer Droid suddenly appear spinning like a wheel and transform into an attacking stance with a clank. It's a well-made model. Destroyer droid, also known as Droideka or Rollies, is an insectoid battle droid. Droideka's weapon is twin blasters attached to its arms. It is a battle droid with a built-in shield generator in the spherical body at the bottom of its torso, which generates a spherical shield to protect itself, making it a powerful battle droid both offensively and defensively.
