Generate a collage that captures the essence of the Manga art style. The collage should be filled with expressive characters, dynamic action scenes, and highly detailed cityscapes. The characters should incorporate a variety of emotions, such as surprise, sadness, joy, and determination, giving a sense of the depth and complexity one would find in Manga. All characters and backgrounds should be full of details which contribute to creating a compelling narrative as typical in Manga. Remember that Manga typically incorporates elements such as speed lines to depict movement and bold, dramatic poses to heighten emotional intensity.
