Guardians, manufactured by Tendrando Arms, were a type of battle droid. This droid was a superior model to the Defender Droid and featured heavily armed, thick arms. It was equipped with gray laminanium armor, mag-shielding that exceeded military requirements, and a vocabulator that faced downwards. A key feature was that the droid could not be deactivated without the correct authorization. Notably, one Guardian droid was deployed to confine Cal Omas to his residence.
