Metal Gear Zeke from the Metal Gear Solid Peace Walker line is an imposing figure that captures the scale and menace of the prototype bipedal Metal Gear. The Play Arts Kai edition from Square Enix emphasizes brutal armor plating, angular panels, and a compact silhouette that hints at the enormous internal frame. The model features a matte gunmetal base with cobalt blue accents along the shoulders, chest vents, and weapon systems, giving it a cold, military presence. Its head sculpt includes a visor-like eye and subtle sensor detailing. The joints are robust, presenting a balance between poseability and a chunky, armored look. Additional hardware such as exposed hydraulics, riveted plates, and a large chest cavity mimic the in-game silhouette. The surface treatment includes light weathering to imply field service, battle scars, and use in harsh environments. Accessories or weapons, if included, attach to modular mounting points consistent with Play Arts Kai design language.

Metal Gear ZEKE is conceived during the Peace Walker era as a prototype Metal Gear built by the Militaires Sans Frontières and their scientific ally Dr. Huey Emmerich. ZEKE embodies the central paradox of the era: the more capable the weapon, the greater the temptation to deploy it in pursuit of political aims. In the game's narrative, ZEKE is deployed as a deterrent against regional tensions and as a demonstration of MSF's cutting-edge military power. As the story unfolds, ZEKE's immense firepower and mobility reveal the thin line between peace and perpetual conflict. The player's interactions reveal that ZEKE is not merely a weapon but a mirror reflecting those who design and command it. The eventual themes emphasize responsibility for weapons development, the costs paid by soldiers and civilians, and the ethical questions surrounding autonomous warfare. The figure captures ZEKE's iconic status in the Peace Walker arc as both a technical marvel and a cautionary tale.
