Guillermo García leads the mercenary group "Armistice Guards" and works professionally as a negotiator for the Tibet-Himalaya United Kingdom government, mediating regional conflicts. A man in his 50s of average height, he presents with a bald head, brown eyes, and corrective lenses, dressing in military or civilian attire. Publicly, García cultivates an image of a benevolent peacekeeper, hailed as a hero for resolving disputes through negotiation. This persona masks his true nature as a cunning opportunist who intentionally fuels conflicts to make himself indispensable. He orchestrates violence between factions, then intervenes to quell the turmoil he created, charging substantial fees for these manufactured resolutions, revealing his disregard for human life beneath a diplomatic façade. He operates primarily through violent subordinates executing his schemes. Jean-Marcel Belmondo acts as García's primary enforcer, committing extreme violence—including the genocide of Tenzing Wangchuck's village—to destabilize regions under García's direction. When Belmondo demands higher compensation, García kills him without hesitation, ruthlessly eliminating liabilities [citation:]. Another subordinate, Tshering Gurung, initially serves García within the Peace Monitoring Group unaware of his leader's duplicity. Upon discovering García perpetuates conflicts, Gurung defects and allies with García's adversaries. García's interactions with Shinya Kogami reveal his manipulative approach. After rescuing a wounded Kogami, García feigns camaraderie, leveraging apparent commonalities to gain trust while aiding Kogami's journey to Tibet. This relationship sours when Kogami uncovers García's conspiracy to sabotage peace negotiations. García's subsequent attempt to eliminate Tenzing—whom he gravely wounds—accelerates his confrontation with Kogami. The conflict culminates in García's death at Kogami's hands during the resolution of the Tibet-Himalaya crisis, ending his cycle of manufactured warfare.
