 A detailed and vibrant illustration of the superhero  Captain Planet. He has blue skin, green hair styled in a mullet, and is wearing a red and white costume with a planet symbol on his chest. He should be in a powerful and heroic pose, standing on a rocky terrain with a background of mountains and a clear blue sky. His muscles are well-defined, and his expression is determined and focused, symbolizing his commitment to protecting the Earth. The colors should be bright and vivid, emphasizing the dynamic and inspiring nature of the character and the scene.
