Zechs Merquise is OZ's most elite soldier in Gundam Wing and one of Treize's two closest companions. While with OZ, he wears a silver mask to hide his true identity - that of Milliardo Peacecraft, one of the two surviving heirs to the destroyed Sanc Kingdom's throne. When his mask shatters in battle, Zechs leaves OZ and becomes a peace ambassador for the Sanc Kingdom. After the Sanc Kingdom is destroyed a second time, he becomes the leader for a rebel organization called White Fang and tries to achieve a total peace through war. An excellent pilot, Zechs uses the mobile suit Tallgeese and the Gundam Epyon.
