A young man with dark hair and blue eyes stares intensely, then the scene shifts to a close-up of a hand gripping a vertical blade, followed by a close-up of a face with wide eyes, then a view from below of massive legs standing on a wooden surface, and finally a figure in a harness flying through the air toward a giant humanoid creature with red markings, all set against a backdrop of a cloudy sky and a city.
