A highly realistic and intense battle scene between Iron Man and a menacing, armored skeleton warrior. Iron Man, clad in his iconic red and gold suit, is in mid-action, raising a gleaming, high-tech sword with a metallic, futuristic design. His arc reactor glows brightly in the center of his chest, casting a blue hue. Opposite him, the skeleton warrior, with hollow eye sockets glowing ominously, wields a dark, ancient sword covered in mystical runes. The background is a desolate, post-apocalyptic battlefield filled with debris, broken machinery, and swirling dust clouds. Sparks fly as their swords clash, illuminating their determined expressions and creating an intense, high-stakes atmosphere. The scene is highly detailed, with realistic textures on both Iron Man’s armor and the skeletal warrior's bones and armor.
