Technical and Historical Notes

Designed during the last days of the "Eve Wars" conflicts of After Colony Era Year 195, the OZ-00MS2B Tallgeese III was intended to be another personal mobile suit of OZ leader Treize Khushrenada. However, its advanced weaponry took a while to develop, and the Tallgeese III was not ready in time for the war's end. However, the completed Tallgeese III did end up in the care of the new Earth Sphere United Nation's Preventers agency, and it would later be used in combat by Zechs Merquise - former leader of White Fang and now a Preventer agent, code-named "Wind." The Tallgeese III made its first appearance during the Mariemaia Army's revolt on Christmas Eve in Year 196 of the After Colony Era. Former White Fang leader Zechs Merquise, who had been presumed dead for the previous year, made a surprise reappearance, joining the United Earth Nation's Preventer agency to combat the Mariemaia threat. Zechs would use the Tallgeese III in combat against the rebellious Mariemaia Army, almost single-handedly destroying or holding off many of their new MMS-01 Serpent units.

The Tallgeese III was a major improvement over the previous Tallgeese and Tallgeese II designs. For close combat, the Tallgeese III mounted a large shield which contained a retractable heat rod similar to that previously used on Zechs' OZ-13MS Gundam Epyon. The traditional pair of beam sabers remained intact, though the addition of a pair of head-mounted vulcan guns for close-range defense was a minor improvement. The Tallgeese III's primary weapon was its mega cannon, which replaced the original Tallgeese's dober gun. The mega cannon was extremely powerful - almost as powerful as the Wing Gundam Zero's twin buster rifle. Zechs used the Tallgeese III's mega cannon to destroy the Mariemaia Army's MO-III asteroid base with one shot.
