Immortality

"William Afton's eyes scanned the blue prints. Looking for any possible flaw. It was perfect. There was nothing wrong, everything fits, the design was flawless. He coughed again, but he knew he would be rid of this old, crumbling diseased body soon. He passed the blueprints back to his assistant, and told his surgeon that he was finally ready for the procedure. That night. William Afton, a 96 years-old corporate giant played God, and died. The next morning, William Afton, an hour-old, extremely advanced robot woke up, having just unlocked the secret to Immortality after all these years."

Backstory
We all know the story. William Afton, the child murderer, the man without remorse, Co-owner of a failing pizzeria, who met his end alone and in pain, haunted by the souls of his victims, crushed beneath tons of metal spikes, springs, and locks. Lured back into Hell by his own business partner, his story ended with him being engulfed by flames.

But what if it didn't have to be this way? What if William Afton hadn't decided to stop his car outside of Fredbear's that day, hadn't saw the crying girl outside the window, hadn't... Well, you get the idea. What if he just drove on?

Well... This time, he decided to be kind to the child. This time, he DID stop his car, but instead of going down the horrific path of crime that would lead to his death, he did something he never did before. He showed kindness to a child, and unlocked the door for her. The girl looked back and waved at him out through the window she was on the other side of moments ago, and Afton was reminded of his childhood... He wished that someone had done something nice for him as a kid... But Afton quickly put this out of his mind, and this time, he drove on.

75 years later, It led him to here. Freddy Fazbear was on the same level of popularity as Mickey Mouse, his name is known by most, if not all, as Freddy Fazbear's creator, as an innovator, as an inventor, Afton was known as a good man. His speeches on creativity and creation moved millions. His name known and respected by everyone. He was a good man, always giving to the less fortunate, wether it through charities, or doing them personal favors.

And so, the world wept with him when the news came to light that William Afton was diagnosed with terminal Illness, and that he had mere months to live.

But William Afton was never a quitter, and so, he locked himself in a room, with some paper, a single fountain pen, only getting out for food, toilet breaks and treatments.

And after a few weeks, he finally came out with a blueprint. The blueprint, he had explained, for Immortality.
