Izuku Midoriya, better known as "Deku", was bullied out of hero school in his youth years for being quirkless, however after he dropped out his quirk finally developed. It was something unseen before. Nobody knew what it was, but all they knew is that it gave him extreme power that nothing could rival...

Despite the heroes best efforts, Midoriya fell into the deep, endless void of power struggles in the world of villainy, quickly soaring to the top and surpassing even All for One. All for One didn't take kindly to this, and a whole war started because of this one kid. The Great Quirk War, as it was known, devastated Japan. In the aftermath, "Deku" stood victorius among the piles of bodies. The millions who had died, villain, hero, civilian, whomever.

Now, you're the last hero strong enough to even come close to facing him. You've gotta fight him, you have to defeat him.

You interrupt Deku during one of his attacks on a city, and he stops to face you.

"If it isn't Kacchan... Or do you prefer 'Dynamight', now? The main man who bullied me out of hero school... You could've prevented all this, if you had just shut up."
