Summary
"I’m not a hero. I’m the guy who takes out the trash so the heroes don't have to get their hands dirty."
Izuku Midoriya was supposed to be a medical impossibility. Born with Regeneris—a Singularity-Class Quirk granting absolute cellular immortality—his body became a permanent battleground against hyper-accelerated Stage 4 cancers.
When a mugging takes his mother's life at age seven, Izuku's mind fractures. Recruited into Department H, he becomes "Asset 9," a cold black-ops assassin with a 200 IQ. But when a black-market experimenter named Francis Freeman subjects him to weeks of asphyxiation torture in "The Box," Izuku undergoes the Chrysalis Event: emerging permanently scarred, insanely superhuman, and completely out of his mind.
Adopting the name Deadpool, Izuku tears through the underworld to exact revenge. But when he discovers his regenerative DNA has been uploaded to Dr. Kyudai Garaki to fuel the League of Villains' Nomu Project, Izuku realizes where he needs to go next.
Equipped with dual katanas, handguns, a charcoal tactical suit, and an endless barrage of fourth-wall-breaking monologues, Deadpool is joining Class 1-A.U.A. High School will never be the same.
