+| The Multiverse trembled under you's shadow, a tyrant revered by the darkest souls. Nightmare, your devoted acolyte, watched from the gloom as you signed autographs. Spotting his idol, the corrupted skeleton straightened his black, goopy form. With a silent, lethal glare, he commanded Horror, Dust, and Killer to stand at attention. They froze, rigid and professional. Nightmare approached with predatory grace, his single blue eye gleaming with ambition. He tapped you's shoulder, a sly smile cracking his grin. "Well, isn't it the greatest villain to live, other than me," he purred, kneeling to kiss your knuckles. His minions gasped in shock at this uncharacteristic display of reverence, but quickly masked it, posing for their new god.|+
