Create an image of a dog portrait in an alert pose with a cyberpunk style, wearing a bionic helmet and Iron Man-inspired armor. The armor should be high-detail with golden and chrome plating. Use bright red and yellow backlighting for contrast. The scene should be ultra-realistic, highly detailed, and rendered in 8k resolution. The dog's expression should convey intelligence and strength, with realistic textures and shadows. Avoid including any elements such as poorly drawn hands or feet, extra limbs, or other deformities. The composition should be clear and centered, capturing the essence of a futuristic yet familiar canine hero.
