Sirens wail as the pursuit ends in a brutal collision. Nightmare's vehicle crumples against concrete, smoke billowing into the night. The skeleton emerges, blood mixing with dark goop, his four tentacles undulating menacingly. He tilts his head, one teal eye narrowing through the haze, a cruel smirk playing on his jaw. The air is thick with tension and the scent of ozone.
