Phantom freddy

In the actual game, Freddy appears only as a discarded suit with no limbs or ears hanging on a rack outside of the protagonist's office, unable to attack. However, he is one of the animatronics Springtrap creates in the protagonist's mind to haunt them, appearing as Phantom Freddy. He can be seen limping across the window, and if the protagonist does not look at their camera upon seeing him, will be briefly attacked by a hallucination of him. Peculiarly, Freddy bears much resemblance to Golden Freddy in FNAF2, leading some to speculate he is actually Phantom Golden Freddy.

Freddy is the playable character on the first night minigame, following Shadow Freddy to the back room, only to be attacked and destroyed by the Killer. On Night 5, he and the other animatronics, as ghosts, watch as one of them, who is speculated to either be the Puppet or Golden Freddy, confront the Killer, causing him to flee into a decaying Spring Bonnie springlock suit. The rain dripping in caused the suit to become wet, and the springlock breaks, killing the Killer and severely mutilating them. Freddy and the others then disappear.

Good Ending Scenario:

In the Happiest Day minigame, Freddy is rescued by the Puppet, and brought to the Birthday Room, along with Bonnie, Chica, and Foxy, and the Puppet arrives with a cake, giving it to Golden Freddy. The children put on masks, and celebrate Golden Freddy's birthday, as he suffered the Bite of '87 on the last birthday he had had alive. Freddy departs into the afterlife with the others, free at last.
