Who is Hybrid?

In the trailer, there saying he will come back, he was always there, and a bunch of other sentences starting with he.

Who is a person who was always there? The Marionette. When you look at Hybrid, he has eyes like the Marionette.

In the trailer Hybrid is sitting down, like the picture you see above. He's sitting like Golden Freddy & Withered Bonnie in FNAF 2. In FNAF 2, Withered Bonnie suddenly turns on. How could that old suit still be working? The Marionette is controlling it to work. In the minigame, it does say he gives life .

In FNAF 3, either Marionette is Hybrid or is controlling him.
