"Generate a realistic image of a superhero from a Japanese children's TV show, similar to a sentai hero. The hero should be dressed in a blue costume and wearing a mask that completely covers their face. The mask should have a prominent lime-green 'Z' design on it. The 'Z' design should be located on the face of the mask, and the hero's eyes, nose, and mouth should not be visible, similar to the appearance of a villain from Kamen Rider's Shocker. The costume should be detailed and dynamic, typical of 'sentai' (super squad) shows, with vibrant colors and intricate patterns. The character should have a heroic and energetic pose, ready for action. Ensure the overall appearance is consistent with the style of Japanese children's superhero shows."
