A powerful and fierce-looking bear standing on the surface of the Moon, holding a large machine gun. The bear is upright on two legs, wearing a futuristic space vest or armor, looking like a space warrior. Behind it is the dark sky of outer space filled with stars, and the Earth is visible in the background. The Moon's surface is rocky and grey, with strong shadows. The scene is dramatic, sci-fi themed, with a cinematic and epic atmosphere. The art style is highly detailed, digital painting or 3D concept art.
