Zechs Merquise (ゼクス・マーキス Zekusu Mākisu, taken from German Sechs, lit. "six"), is one of the main characters from Mobile Suit Gundam Wing. Renowned for his amazing skills in combat, his exploits earned him the title Lightning Count. A personal friend of OZ leader Treize Khushrenada, Zechs was often the commander of important missions, and received his orders directly from Treize. His true name is Milliardo Peacecraft, the long-lost brother of Relena Peacecraft and the heir to the Sanc Kingdom throne, a country known for its commitment to pacifism. After the destruction of his homeland by UESA forces, he donned his iconic mask and left behind the name Peacecraft, for his new moniker, Zechs Merquise. He is Heero Yuy's primary rival throughout the series.
