We all know the story of Izuku "Deku" Midoriya, or what has been revealed so far. We know of the two powers at constant war: Heroes and Villains.
The constant struggle against these two factions leaves the smallest ripple in the ocean of history. Even before quirks, heroes rose to the challange to face the evil that threatened the peace of the world. May it be the police who risk their lives protecting civilians or the soilders that face those who wish to rule everything. But now the war continues with one fact: the war will never end.
When mankind first recived Quirks, the planet's many society's were plunged into chaos. People who remained quirkless feared the Quirked and what they could do. What they were capable of. Amongst the mayham, one man stood out amongst the rest, one that would shape the history of what was to come. His name has yet to be know and is only named by the quirk he has...All For One. This man wanted society to bend to his will as his dream was to shape the world in his image. But that was impossible at that moment in time. He had no real power at the moment, no influence. Than there was his brother. Another unnamed man that would only be know at the moment as First. The reason why?
First would be the , well, first to hold the fire that would also shape the future. Originally, First was thought to be quirkless, so out of pity, his brother AFO gave him a quirk, one that stock piles power. But in truth, the future Underworld king's brother already had a quirk, a quirk that allowed the holder to pass on a quirk. Both powers in a spotaneous mix, combined to form the legendary superpower that would be passed on through 8 generations, now being used by the 9th.
And over the 100 years he's lived, the two quirks of All For One and One For All have been faced in battles since the begining. But there has been a supported truth in the world of quirks. Each generation born had more powerful and uncontrolable quirks. From simple powers like low-level healing and weak telekinesis to the power to create entire icebergs out of thin air and to generate city-wide earthquakes with a single step. With this proven fact know, no one has yet to think of one fact; one day there will be a quirk stronger then any yet. One to surpass the lives of One For All and All For One, even in their primes.
And so this is where this story will begin. When one person, thought be quirkless like First, actually had a power beyond the Underworld King and the Symbol of Peace. This story will form the unlikely alliance between two factions, who have no other choice but to unite as one. Villains become heroes in this story but they're still bad. With no other choice, both the Leauge of Villains and the Eight Precepts of Death come together to face an enemy that even the heroes need help with.
Together, in a mission that is labled suicide, the villains march into battle to become the worst heroes...but they're all we've got...
