Phantom Bonnie

Phantom Bonnie, also known as The Lost Phantom, was supposed to be a part of FNAF3, but he wandered off and didn't make it to Fazbear Fright in time to join. As a result, he was replaced with Phantom Toy Foxy instead. We later learn that the place he was in was Waste Management, and he didn't know that as a phantom, he could teleport, and he also thought he was supposed to meet at Scott's house.

He later finds himself with the others, and becomes a Nightmare animatronic. He has Determination just like Frisk, and also has the White Lantern Ring. Yet, he can also be one of the most insane animatronic of them all.
