That's all the evidence I have, though it sure is a lot of evidence, and it solves three mysteries in one, three mysteries that seemed to not link at all are solved by the same story, that we use evidence to find. The Shadow Animatronics ARE the temporary suits that we had no idea what they were, and Fredbear is given a purple hat to differentiate it with the classic Golden Freddy, as going into THAT suit means you die. Go in the suit with the PURPLE hat, not the BLACK hat, employees. ;)

So, in a sense, Shadow Freddy is a type of GF.. Though he can't BE GF, as the two behave in different ways. One does obsolutely nothing but teleports in and out of Parts and Services, the other turns into a head and jumpscares you. Speaking of which, maybe Shadow Freddy's deed isn't actually his fault.. As he is indeed a springlock-The temporary suits, Purple Guy could have worn Shadow Freddy.
