Springtrap

If ya ask me on the matter, Springtrap makes the most sense for a possible FNAF rep.

If anyone makes it in, it'll probably be Springtrap. He's already a sociopathic serial killer, so he'd fit in perfectly.

I already know because they already announced it

I can't remember them making an announcement of Springtrap getting in. I know one of the devs has expressed interest in adding him, but not much beyond that.

Well it’s more of a trailer
