(This is an Alternate version of my story Immortal) Amy Williams, born during the Dawn of Quirks, became a mercenary alongside her brother after the tragic death of their father. Over centuries, she transformed into a feared terrorist, known to both heroes and villains as the Nightmare. 195 years later, Amy discovers an abandoned baby boy with striking green hair. Choosing to adopt him, she raises the child as her apprentice, honing his skills to match her own. Fifteen years later, the world is introduced to a new vigilante, one whose actions will shake the hero society to its core.
