Muscular, naked man standing in a dark, damp mining tunnel, his body covered in sweat, mud, and combat marks that highlight his defined torso, abs, strong legs, and visible penis. He holds a pickaxe resting on his shoulder while looking to one side with a serious and alert expression, like in a science fiction or underground survival scene. His right arm incorporates mechanical pieces or technological implants with blue lights, creating a contrast between human body, metal, and industrial environment. The tracks on the ground, wet rocks, and intense blue lighting reinforce a dramatic, rough, and futuristic atmosphere.
