Zechs Merquise is the secondary antagonist of Mobile Suit Gundam Wing. He is a Colonel in the OZ special forces and a close associate of Treize Khushrenada. Secretly, he is actually Prince Miliardo Peacecraft of the Sanc Kingdom, a nation conquered by the Romefeller Foundation. After leaving OZ, Zechs joins the White Fang and becomes their Commander-In-Chief to lead them in creating a world without conflict. He later appears as one of the main protagonists in Mobile Suit Gundam Wing: Endless Waltz.



Milliardo Peacecraft was among the heirs to the Sanc Kingdom throne, until the attack by the United Earth Sphere Alliance. Ever since that incident, he donned his signature mask and alias Zechs Merquise to join the Alliance and eventually OZ in order to exact revenge from within.

He would in his shuttle first encounter Gundam pilot Heero Yuy entering Earth to commence his attack. He and his underlings would try to pursue and shoot down Heero's machine. Zechs would then go into a Leo and manages to shoot at Heero's spacecraft, which then transforms into the Wing Gundam. After Heero takes out two pursuing Aries, Zechs would take his turn and grapples onto the Wing Gundam; he then exits the cockpit, parachutes himself, and leaves the weight of the Leo to drag the Wing Gundam down into the ocean. He would then get picked up by his shuttle. He would later report to Treize, who sends him to retrieve the fallen Gundam.

Zechs and his team would search for the Wing Gundam; however, once they found it, the salvaging team gets assaulted by Duo Maxwell's Deathscythe Gundam.

After that incident, he would eventually receive the Tallgeese at the Mediterranean base at the same time Trowa Barton assaults the Corisca Base with his Heavyarms Gundam.

Zechs appears as a member of the Preventers, a peacekeeping organization led by Lady Une formed to prevent conflicts and wars from breaking out.




  • Zechs Merquise's silver mask, red uniform and secret identity as an exiled prince and brother of the female lead make him an obvious homage to Char Aznable from the original Mobile Suit Gundam.
