A newly built version of the Tallgeese with parts from Gundam EPYON.
In AC 196, when the Mariemeia Army declared war on the Earth Sphere Unified Nation, former OZ ace pilot Zechs Merquise returned from hiding to work for the Preventers. Zechs was assigned the code name Wind and given Tallgeese III to fight against Mariemeia's Army. Zechs would later use the Tallgeese III to pacify Mariemeia's army of MMS-01 Serpent's in Brussels without killing any of the pilots. The Tallgeese III's armament was expanded from the original Tallgeese. It sported a pair of head mounted vulcans, a pair of beam sabers, a retractable heat rod (similar to the one previously used on Zechs' OZ-13MS Gundam Epyon) and a mega beam cannon similar to the Wing Zero's twin buster rifle. The mega beam cannon was powerful enough to destroy the asteroid base MO-III in one shot.
