Create a Gundam figure inspired by Captain America. The figure should feature a robust red, white, and blue color scheme with metallic armor. The chest should have a star emblem, and the design should evoke a strong, heroic presence. The figure should hold a large, circular shield with a metallic finish, designed like Captain America's, attached to one arm or mounted on its back. In the background, the box art should showcase the Gundam in a powerful battle stance, with the shield prominently displayed in mid-action, deflecting energy blasts. The box should highlight key features like the shield, reinforced armor, and tactical weapons, set against a battlefield scene with patriotic colors and bold lettering. --niji 6
