Is Puppet possessed by Charlie?

When the Puppet gets free, Charlie jumps up and down to get it’s attention, before fading away, as William kills her. Once the Puppet gets outside, Charlie’s body lays on the ground, and the damaged Puppet hugs her corpse, allowing Charlie to possess it.

Who becomes the puppet in FNaF?

While it was confirmed that Puppet’s soul is female, both The Freddy Files and Ultimate Custom Night confirm that The Puppet himself is a male. It was unclear whether the original Puppet was present in Fazbear’s Fright. It was eventually confirmed that he was present post FNaF 3.
