When I was a child, William told me about my destiny of being his successor. He said that I would be the one to take charge of the Fazbear Entertainement and change the world to the way I want. But everything changed when my sister was born.

My father started to only care for her, making everything she wished to happen and ignoring me. Even when my brother was born, he only cared for her. When she died, everything changed. Mother left us and William only caring for his work, leaving me and my brother alone in the house. I was a foolish child and in a desesperate attempt of alleviating my rage and pain, I started to bully my brother using his fear of animatronics, until I was too far.

It was my brother's birthday party, even with my brother fearing the animatronics the party was in Fredbear's Family Dinner. Me and some of my friends started to make fun of him until we had the terrible idea of putting my brother's head into Fredbear's mouth. My brother begged us to stop, he cried desperately and the worst happened. Fredbear bit my brother's head, the blood started to appear and I realized what I did to my own brother.

When me and William arrived home, he started to torture me. I was tortured for an entire month, physically and mentally, until William said that if I wanted to finish the torture, I had to survive his test. I accepted it, not knowing what he was planning to me.

He left me alone in the house, making sure that there was no way of escaping, and every night he sent his animatronics with the mission of killing me. I only had one lantern to help my survival and nothing else. During 8 days I had to survive William's test, remembering of everything I did to my brother. It was terrible and I almost died some times, but finally the ninth day arrived and the test was finished.

When William returned, I was expecting to him being surprise of seeing me still alive, but he already knew that I survived his test. He was using hidden cameras to make sure that I wouldn't escape and the house was full of traps to kill me if I tried to escape the house. He knew that I would survive his test, saying what turned him of my father to a monster:

"The least you could do was survive my test. If you failed even that, I would personally erase your existence from history and make another son to be my heir."

Since I passed his test, William decided to train me to be his successor. Even hating him, I knew that he would kill me if I refused his training, so I decided to be his disciple. He started to teach me about how to manage a company, showing to me the best choices to made and how to deal with rival companies. After that he taught me about robotics, especially how to create animatronics and how they worked, showing the possibility of giving animatronics different functions. And after that, he tought me his darkest secrets.

William was a serial killer that kills children to experiment with their souls, creating an advanced technology that he sells to everyone who has a lot of money. He tought me how to use any weapon with efficiency, from knifes to rocket launchers. He tought me how the best ways of torturing and experimenting with persons and souls, even forcing me to kill innocents. To make me more useful, he decided to send as his representative, travelling to different places and making the world worst and making William more richer.

While I was working for him, William started to seek more knowledge, discovering the existence of magic, the existence of living creatures in others planets and more, but everything changed with the rise of the heroes.

When the heroes arised, everyone discovered the existence of magic and aliens. These heroes started to be a menace to William's plans, since there was the possibility of they discovering his crimes. The heroes couldn't discover most of his crimes but there was one crime that he was considered suspect that could destroy his entire life: the first five kids he murdered and put their bodies inside the animatronics suits.

He went to the old pizzaria, the place where the suits were located. With an axe, he destroyed the animatronics but he didn't realised that the children's souls were released and now could kill him. Desesperate, he went to an old SpringBonnie suit thinking that it was his only hope to stay alive. But he forgot about how the suits worked and as a result of an old springlock suit being used, it killed him, making him suffer a horrible pain before dying and having his souls trapped into the suit.

With his disappearence, I became the new owner of the Fazbear's Entertainement and Afton Robotics, now using what I learned with him to survive this new businnes world. But there was still one thing left to do…

A red-and-white 1958 Plymouth Fury stops in front of an abandoned pizzaria. A man and a woman get out of the car, the man wearing a clean purple suit, looking like a serious businnes man, and the woman wearing a white rabbit suit with red eyes, looking like a mascot from the 80s. It was a silent night with no sound, until the man speaks.

- I'm going inside. Vanny, stay hidden and stop anyone of entering the place. Christine, be prepared to take us out of this place when I finish.

The woman, now called Vanny, looks a little uncertain about the order she received, while the car, now called Christine, turn on her headlights twice to show that understand the order she received. Vanny, still uncertain, speaks:

- Michael, are you sure abou that? I know that is-

- Vanny, this wasn't a request, it was an order. Do you understand it?

- Ok! Ok! You don't need to be angry, I will make what you said to me.

Michael enters the pizzaria, looking at the remains of a place of an old time, a time that will never come back. He look at the stage, a place where the animatronics would sing and tell stories to the kids, now an abandoned stage showing how the pizzaria was abandoned. But he isn't here to make a tour and finally he finds what he was looking for.

The pieces of the four animatronics: Freddy, Bonnie, Chica and Foxy. Spread on the ground there are the pieces of the famous animatronics, but he doesn't want their pieces, what he wants is behind the fake wall.

After taking a deep breath, he starts to say his final words to what he once called father:

- William. It's me, Michael. I did it. I found it. It was right where you said it would be. The heroes were all there too. They didn't recognize me at first but then they thought I was you. And I found him. I put him back together, just like you asked me to. He's alive now. But something is wrong with me. I should be dead. But I'm not. I've been working in the shadows. There is only one thing left for me to do now. I'm going to burn this place. I'm going to kill you.

Michael drops a lighter on the ground, and fire starts to appear, consuming the entire place. And thing that was once called William Afton say it's last words:

- Goodbye, Michael.

Michael gives a final look to the wall that hides a monster from the rest of the world, and say his last words to the man that he once called father:

- Goodbye, father.

Michael leaves the pizzaria on fire, Vanny is already inside Christine and both are waiting for him. Michael enters Christine and knowing that the authorities will arrive soon, the car immediately starts to flee the scene.
