M'Quve, a colonel in the Principality of Zeon's military during the One Year War, operated directly under Kycilia Zabi's command. His primary responsibility was overseeing the critical Odessa mining base on Earth, managing mineral extraction, transportation, and defense while actively concealing the operation's scale from other Zabi family members like Dozle and Gihren. He possessed a calculating, bureaucratic personality, excelling at political maneuvering but showing little empathy for frontline soldiers. His ruthless tactics included cutting off supplies to Ramba Ral's unit to protect Odessa's secrecy and later abandoning Solomon survivors during escape. Overconfidence often led to operational failures, as he rarely planned for contingencies. Outside duty, he prized his collection of antique ceramics, particularly white porcelain vases from China's Northern Song Dynasty, displayed prominently in his office. During the Odessa campaign, M'Quve attempted to thwart the Earth Federation's advance using sabotage and deception. He collaborated with the traitorous Federation general Elran to delay Operation Odessa and personally threatened a nuclear missile launch in violation of the Antarctic Treaty when overwhelmed. This missile was launched but intercepted and safely disposed of by Amuro Ray in the Gundam. Following Odessa's fall, M'Quve retreated to space, boasting Zeon could "fight for another ten years" with the resources he secured. Commanding relief fleets in space, including operations near Solomon, M'Quve initially attempted to abandon escape pods carrying Dozle Zabi's wife and daughter during a rescue before absorbing retreating troops. His final confrontation occurred near the Texas Colony, piloting the customized YMS-15 Gyan mobile suit against Amuro Ray's Gundam. He employed traps like asteroid explosions, airlock bombs, and floating mines but was defeated in melee combat. Before dying, he entrusted a white porcelain vase to his subordinate Uragang for delivery to Kycilia. In the Movie Trilogy adaptation, *Soldiers of Sorrow* omitted his nuclear threat at Odessa, communication with Elran, and piloting of the Adzam. *Encounters in Space* excluded his Texas Colony death entirely; he appeared alongside Kycilia after Solomon's fall and survived the narrative. The *Char's Deleted Affair* manga aligned with this film continuity, depicting his death during A Baoa Qu's fall while escorting Zena and Mineva Zabi, killed by a Magellan-class battleship's main gun. *Mobile Suit Gundam: The Origin* offered an alternate depiction: M'Quve commanded Zeon's Earth Invasion Force, orchestrating Admiral Revil's covert release to prolong the war. He later attempted nuclear strikes against Revil's fleet, foiled by Cucuruz Doan. During the Odessa retreat, he piloted the Gyan to cover his forces' escape before detonating an underwater nuclear missile, killing himself and surrounding Federation troops. A hallucination of M'Quve later appeared to chastise Uragang for disobedience. Other media, like the video game *Gundam Battle Operation 2*, referenced a ceremonial MS-07B Gouf mobile suit customized for M'Quve with gold engravings and a spearhead antenna, though he has no combat records piloting it. In later Universal Century timelines, such as *Mobile Suit Gundam GQuuuuuuX -Beginning-*, he held the rank of vice admiral by U.C. 0085 and expelled subordinates Gaia and Ortega from Zeon forces. M'Quve consistently prioritized Kycilia Zabi's interests, blending political acumen with tactical opportunism. His actions focused on resource management and clandestine operations over frontline command, while his antique-collecting habit provided a glimpse into personal motivations. Across iterations, his legacy remained tied to Odessa's operations and final confrontations with the White Base and its crew.
