(I'll be using the book "The Silver Eyes" and the games for evidence)
Ever since the first game of the FNAF series was released by Scott Cawthon it has been debated on who in the world is the purple guy I have played all the games, including Sister Location. Now before I continue you should know this, the order of the FNAF games by date taken place in is FNAF 4, FNAF 2, Sister Location FNAF 3 and FNAF 1. Ok so here we go. Before FNAF 2 which according to date is the first game in a pizzeria there was another pizzaria called Fazbears Family Diner which is mentioned in the book. Now Scott did say the book was in a whole different universe but I think that he changed his mind about that because in Sister Location a guy named Mr. Afton is mentioned in the opening credits of the game and the only other place where this Mr. Afton has been mentioned is in the book. Now people have said Mr. Afton is purple guy. This theory is incorrect because in Sister Location you play as Mr. Afton (thats been confirmed) and at the end where you are killed in the scooping room it shows a silohoutte of you standing in the mirror with purple eyes therefore purple guy killed Mr. Afton and took over his body. Now who is the purple guy. The purple guy was a friend of Mr. Afton whos heart went cold. In the book it mentions the 6 missing children case and it says that the kidnapper was wearing a yellow bonnie suit. The yellow bonnie suit was none other then Springtrap and inside the suit was the purple guy. He put the kids in springlock suits and eventually the springlocks releases killing the children inside. Then the spirits of the children possessed the suits. Now why would the animatronics attack you if they where possessed by inocent kids. If you notice in every game except for FNAF 4 which is in my opinion a nightmare of a boy the victim of the bite of 1987. Now in rhe game you here the voice of a girl which has been confirmed as Mr. Afton's daughter and she was the victim of the bite of 1983. The victim of the bite of 1987 is Mr. Afton's son. Now in the book another daughter of Mr. Afton is mentioned and a brother is mentioned the boy the victim of the bite of 1987. The first daughter, the victim of the bite of 1983 died before the brother or the sister , who were twins, were born. Now back to my question why would the animatronics try to kill you if they are possessed by inocent little kids. The answer is they hate adults they where killed by an adult therefore they hate adults. Purple guy was wearing the Springtrap suit as a costume but it had springlocks in it that came loose and killed the purple guy. Then purple guys spirit possessed Springtrap and an animatronic in Sister Location know as Ennard which is the animatronic you see in the window of the scooping room at the end of the game. Purple guy needed a body in order to leave the FNAF world. Now I have studied the maps of all the games and I think that every FNAF place is connected by series of tunnels and Sister Location is under the house from FNAF 4. Now I think the reason that all of the locations are connected is because Mr. Afton didn't want to be far away from his second daughter after what happened to his first two children. Now after Purple Guy takes your (Mr. Afton's) body he still possesses the other animatronics. Thanks guys for reading this and if you think my theories not true ask the creator of the game Scott Cawthon. Now I know my theory might not be 100% correct but it could be somewhat true. So if anyone has a way of getting in touch with Scott then please ask him about my theory and give me your feed back. And like always I will see you.....in the next theory byebye
