The Gelgoog Cannon is equipped with a specialized head unit and mounts a powerful beam cannon on a modified B-type backpack, and even with it, the suit's reactor is still powerful enough to support other weapons systems. This meant the Gelgoog Cannon could carry beam rifles and bazookas, or even swap out the forearm jet engines to mount optional missile launchers. For defense, the Gelgoog Cannon could be equipped with a buckler shield, a small arm-mounted shield, in place of the forearm jet engines on the left forearm. As the Gelgoog Cannon made use of the B-types powerful backpack, it had enough thrust to keep itself maneuverable despite the added weaponry weight. The suit soon proved itself a capable fire-support and anti-fleet unit.
