It all began when a mysterious figure walked down the street, shrouded in a heavy overcoat, their face hidden by a hood. The figure moved with a strange grace and a casual indifference to their surroundings, as if they were not really a part of the physical world. Suddenly, this mysterious figure crossed the road and came to an abrupt stop. Without warning, they thrust out their hand and stopped an entire train with its force. People were shocked and confused by this unpredictable act, but that was nothing compared to what happened next. The figure then thrust out their arm and punched the air. An explosion followed, and after the smoke cleared it was revealed that the shockwave from their punch had destroyed an entire city! The news quickly spread, and the world and the United Nations were quick to respond. Representatives from all around the world gathered to discuss what had happened, and put into motion plans to ensure that such an event could never happen again. The mysterious figure was never seen again, but the shock of what had happened could never be forgotten. That chilling day, one person had changed the world with a single act.
