So I've had this idea for a while, made this a few months ago, though I never finished it. I've seen a few au's of Jack being the puppet instead of Dee, but I had the thought of, "What if he was his own uniquely designed animatronic?" So, yeah, that's how this was created. This definitely isn't my final design; I probably want a longer snout and to add some teeth to it, but this is a basic beta design.
Lets get to the interesting part.
LORE: In this au, everything goes as normal, but what if Peter had picked up Dee from Fredbear's family diner before Jack had come? Well, Dee and Peter are alive, but Jack wasn't told that Dee wasn't in the diner. He's springlocked as usual, but here, Fredbear doesn't bring him back; his soul acts similarly to Dee's, whispering the crimes of Henry and Dave to customers. This results in Henry creating "The Hound" (I haven't gotten an idea for the name yet, okay?)
Fredbears Design (Aka The Hound): Henry had quickly put the vessel together, not bothering to make sure each part fit together correctly. It's sloppy, unfinished, but it works in trapping Jack's soul. But why is his main design so different? Well, after Fredbears closed, Jack rotted for a few years until he was salvaged by Fazbenders. They gave him a new color and made him appear less deformed, though still a bit goofy.
Does he work as a spring lock suit? Short answer? No, though he originally did. In Fredbears, he was functional, but after years of rotting, the endoskeleton within the suit had slowly rusted and ended up combined with the costume. This made it impossible for the suit to be changed from animatronic mode to suit mode, much to the annoyance of the company. He does have a withered design in the works, but I haven't drawn it yet. The concept is that the stomach of the animatronic is ripped open, exposing the springlocks within. Along with a crooked jaw and other areas of damage and holes.
His opinions on Henry and Dave? Well, he definitely hates Henry, trying to attack the guy whenever he can, but with Dave, it's a different story. They kinda act like Steven and Dave from DSAF 1, not friends but on neutral terms, this being due to Dave not having killed Dee in this au or being involved in Jack's death like Henry. Maybe the au could have davesport? I'm not fully sure about it, but at least maybe have them have an uneasy alliance.
Communication? My idea is due to him being an older animatronic (and the mention of the animatronics not talking and only growling by Henry) he speaks through devices like radios. This is based on how Henry discovered souls through the radio of his car.
Ao3 fics are allowed (please, I will go insane if I get an Ao3 fic for this). I do plan to make my own at some point, but I just have no idea what it would be about or where in the timeline it would occur. If you have any ideas, please tell me because I'm honestly lost to where I should go with this.
