Boku no hero academia X Fullmetal Alchemist, D-Grayman, One Piece, Fairy Tail, and Akame ga Kill Crossover that nobody ever asked for. I was really inspired by all these stories and decided to cram them all together into one story.
Summary
In 2039 archeologists discovered ruins of an unknown civilization that was later found to be over 7,000 years old. The news of the ruins fascinated both the historical and scientific community because of how similar the ruins were to modern-day buildings. They managed to retract records from the ancient ruins and were prepared to decode it until in 2051 quirks began appearing all over the world. As the world struggled to adapt and control this new superhuman society, the research was eventually abandoned and completely forgotten. In 2320 nearly 80% of the world population has a quirk with the quirkless population seemingly slowly being driven to extinction. In this quirk society, a new profession "Heroes" that was long thought to be a dream had become a reality. A young boy named Midoriya Izuku dreams of becoming like the number one hero "All Might." When it was discovered that he was quirkless it all seemed like an impossible dream. However, unbeknownst to the boy, fate had already set its wheels into motion.
