Make this colossal humanoid mech with an upright, slightly forward-leaning stance. Focus on layered gray armor with black underlays, beveled edges, subtle scratches, and vents for realism. Include exposed hydraulic pistons at elbows, knees, ankles, and shoulders. Build a narrow dual-lens visor cockpit with an armored helmet, and integrate arm-mounted energy blades, stowed shoulder cannons, and wrist grappling claws. Add tiny indicator lights along joints and subtle glows along hydraulics, and emphasize twin energy reactors, back thrusters, and stabilizers. Prioritize mechanical realism and engineering detail, making arms and legs modular and articulated, and keep weapons visible but integrated.
