Create an ultra-realistic image of a futuristic robot engaged in combat with a well-armed opponent, showcasing intricate design details and an aura of mastery. The robot should be adorned in golden hues, standing at full height, with a cinematic composition that highlights its high-detail armor and advanced weaponry. Utilize cinematic lighting to accentuate depth of field and the ultra-wide angle perspective, ensuring a hyper-detailed portrayal with beautifully color-coded and graded elements. The scene should be rendered with expertise, invoking the powerful capabilities of Unreal Engine, with stunning background elements that complement the action. Avoid any deformation or disfigurement; focus instead on articulate design and polished aesthetics, capturing the essence of innovation and strength.
