As part of Selvaggio's plans to re-militarize the Earth Sphere, he ordered the construction of a personal mobile suit for his use. Not having the time to completely design and build a new model, he instead had engineers use parts leftover from the construction of the Tallgeese II and III and modifiy the design to his tastes. The resulting mobile suit, the EDO-MS00 Tallgeese "Sigma" was an agile, powerful suit like its predecessors, and boasting extra firepower in the form of arm-mounted beam guns and a wider range of armaments to mount on the shoulder hardpoints. While outperforming the mass produced suits being fielded at the time, it was still a small step below Milliardo's OZ-00MS3 Tallgeese Custom in terms of overall performance.

The Tallgeese "Sigma" first saw combat in November of AC 216, when Josie Selvaggio took it into battle against rebel Preventers under the command of Lady Une. The appearance of this blue and black mobile suit would likely have spelled the end of the Une Conflict, but for the timely intervention by Milliardo's rogue daughter Sidra, who had taken the Tallgeese Custom to Earth earlier that same year. It would not be the last time that Selvaggio personally entered combat with his agile mobile suit, as the Tallgeese "Sigma" would continue to be used as his personal mobile suit throughout the Venusian conflict.
