Heavy super battle droids were a variant of the B2 super battle droids in use during the Clone Wars by the Confederacy of Independent Systems. The heavy super battle droids were larger and featured a more powerful laser cannon than the standard model and featured gray armor. These droids were produced in Geonosian troop centers. The laser cannon took the place of the droid's left arm. A force of these droids escorted the Confederacy General Sev'rance Tann to a meeting with Boorka the Hutt.

Heavy super battle droids were used throughout the Hunt for the Decimator in the year 22 BBY. Following the execution of the Separatist Council three years later, all units of the Separatist Droid Army were shut down.
