ProdigyMecha Inside a giant rotating O’Neill cylinder space colony with its own artificial sky and cityscape, a green-and-white mecha fights a black enemy mecha along the curved “ground” surface. Buildings and parks stretch upward into the distance due to the cylinder’s curvature. The two mechas crash through residential towers while fighting. Artificial sunlight from the long central window strips creates dramatic lighting. Cinematic interior space battle, hyper-detailed, photorealistic, 8K.
