Golden Freddy(FNaF 2)

Golden Freddy return in Five Nights at Freddy's 2, now still a ghost/empty suit.

Golden Freddy is a ghost
This theory now make more sense, since Golden Freddy have shadow when he is in The Office.

Golden Freddy is a empty suit
This theory was simply believed because of Night 6 phone call, also Golden Freddy get incredibly active in that night, also because of the wires in himself.
