Purple Guy

The purple guy, might be possibly an antagonist, who is never shown in the game. Also, he doesn't have any official name or appearance, only knew that he is complete colored with purple. He is shown in the FNaF's Death Minigames(who maybe can make an appearance in the second game).

Appearance
In this game, he does not appear anywhere, and even more mysterious than Golden Piglet. He seems to be somewhat a cop, that has his uniform also purple. He has mysterious eyes, that can sometimes go whole black with white pupils, or completely go white with "panda eyes".

In most fan arts, purple guy is also seem to be holding a bleeding knife or a purple phone. It's unknown whether he has any hair, as some art has while some art makes him bald.

In FNaF's minigames, he seems to be more different. He has brighter pink skin rather than purple, smiling with no pupils in two of the minigames.

History
Purple Guy may possibly the killer, because, most of the time, fan arts of him has blood on his uniform or even his face. Plus, in FNaF's death mini games, he is somewhat holding a banana thing that shaped like a phone(which can make him George) or maybe it is a hacking device, because in the time he sees Freddy, he runs towards him and as soon as he touches Freddy, the game crashes with blue background, and at the left corner it writes "You Can't".

However, in other mini games in FNaF, his appearance is more different. He seems to be a killer, as he kills the child that cries outside and leaves. This can assume he is more a killer rather than a cop.

In the plot, the Purple Guy is inside the news, which can make him the killer of the five dead children who become the Animatronics. Nobody knows him by the time because he is possibly using Golden Piglet suit to hide his appearance. Also, once he murdered the children, it's unknown whether he is caught or not. Most of all it is possibly yes, but after 30 years later, he could be released from crimes.
