Since no-one requested this or perhaps thought of it I'm going to request myself to do a Yandere Fnaf 1, 2, 3, and 4 and do a marathon.
So I list them out and you pick whick ones you want me to do, ok?
Yes I know I ask myself a question/request.
But here is how I think FNaF 1 is:
Freddy Fazbear in my opinion is a gentleman and a loving and caring yandere.
Bonnie the bunny in my opinion is energetic and also a loving yet delusional yandere
Chica the chicken I would say is a lovable and energetic yandere.
Foxy the pirate is a can be bold but yet shy at the same time but mainly bold but I would say he is a caring yandere, but, I would say he is also strict
Golden Freddy/Goldy I would say is a mysterious yandere and a caring yandere
Mike Schmidt/Night Guard I would say is a loving yandere who only wants to keep you safe.
