When heroes break, who comes to save them?

People crave heroes.
But nobody tells you what happens when a hero breaks.

Here is a theory/an alternative version of the superhero story called my hero academia, that I wrote.

Mystery:
Why would Midoriya lose control? Why would a hero turn into the greatest threat? Why would One for All betray its own destiny?

Mindgame answers:
Level 1: Midoriya’s dream was never just saving people. It was saving everyone — heroes and villains. Even the broken ones.
Level 2: Villains are not evil by nature. They are victims. Broken by an unjust world. Shigaraki. Toga. Twice. Dabi.
Level 3: During the Great War, Midoriya’s mind snaps. One for All reaches singularity. Midoriya becomes a monster. He kills Bakugo. Destroys Ochaco. The hero becomes the enemy.
Level 4: Shigaraki steals One for All. Midoriya, powerless, exiled, crushed by guilt, disappears into the darkness. Humanity loses its symbol of hope.

Theory:
When everything seems lost, a hidden alter awakens: Retour.
Midoriya’s secret power: the ability to recover stolen alters. A power born from a hidden truth — he is the son of All for One.

Climax:
Midoriya fights himself — literally — a dark version born from his failures.
Final choice: destroy himself to protect the world.
He wins. But not without sacrifice.
Broken, dangerous, he chooses exile.
He disappears.
The world heals. Slowly. Painfully.

Endgame:
Years later.
A bar.
A screen.
A hostage situation.
No heroes. No powers. Only one weak boy stepping forward to save other un-powered people.
Midoriya watches silently.
One last time, he gives a spark of power to the young boy...

...before vanishing forever into the night.
