Let's talk more about one of the most mysteries characters of the series, who is the series, who is always present in each game,well Origin Cyan, the Golden Cyans and Shadow Cyan are the same clone of course!Yeah that's right! As I said of the cloning machine used for him was old with issues, he's evil at night and has different colors. Through the years, his colors change and his cloning material keeps melting. Of course, the machines were working better since FNaC1. Note that his FNaC1 appearance is now like that, this one here is the old design. So, he becomes more and more Shadow Cyan, notice the the half of Nightmare Golden Cyan's body is just Shadow Cyan! When he becomes Shadow Cyan he's still possessed by Blixer. Crazy, but... very cool. Since his plans didn't work so well, he time travel and brings Golden Cyan from FNaC1,2,3 and 4 with him, which leads to bite of Origin Cyan. That's not really making sense, because remember Golden Cyan from FNaC3, Nightmare Golden Cyan and Shadow Cyan are possessed by Blixer, what they do is just attack the night guard in FNaC5 who just... Blixer. I guess each Golden Cyan saw and came with Shadow Cyan after the Events of each game. During his quest, he appears in FNaC2 as an Easter egg to mess with Melusine mind. I suppose he can mess with people's mind, and that why we see him as a hallucination in the games I suppose. Of course, he bridged each Golden Cyan to his original time. And Shadow Cyan went his own.
