"Generate a realistic image of a superhero from a Japanese children's TV show, dressed in a blue costume. The hero should be wearing a mask that covers their face, with a prominent 'Z' design on the mask. 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."
