Futuristic Humanoid Robot Sleek Metallic Body

Create an image of a futuristic humanoid robot with a sleek metallic body. The robot should have long, silver hair and a flowing, dark cape draped around its shoulders. Modify the body to include angular armor plating with glowing blue accents instead of orange, while maintaining a streamlined design. The background should be a gradient from dark gray to black, emphasizing the robot's silhouette. Ensure the face has a neutral expression and lacks any visible human traits, focusing on mechanical features instead.
