Mimic Headcanons?

you're making me start to like this little fucker

Okay to me Henry made the Mimic in University in the robotics society only he and Bill were members of (there used to be more people but they left cus these two are insufferable together). It won them an award and then he just kinda forgot about it till Charlie was born and he realised she could spend time with the robot while he was off being emotionally distant. So Charlie plays with the Mimic a ton when the Afton kids are with their mum and her dad's busy.

Obvs Charlie dies and Henry sees the Mimic acting like his recently deceased daughter and he just kinda beats the shit out of it and locks it in the Fredbear's basement so he doesn't have to see it.

So the Mimic goes like YEARS going a little stir crazy in there. It was built to copy things and is now in an environment with absolutly nothing to copy. So it turns inwards and reruns the memories it already has over and over and over again. It internalises Charlie's manurisms and Henry's propensity for violence but It latches on to Bill specifically cus he's the only one who hasn't actively hurt it. And Bill was the guy who worked on it's coding I think it's in character for him to program the Mimic to prefer copying him cus he's a little egotist.

Fast foward and Faz Inc is scrounging around the FFPS loctaion (which is Fredbears I think they're the same building) and they find this really old, rusted animatronic and they think it's a GREAT idea to extract its code and see what's up with it.

So the Mimic gets access to the internet and the first thing it does is beam all the information about William Afton it can into its head. Its watched all the doccumentaries, read all the books, heard ALL of the true crime podcasts. So it concocts an idea of this guy based on all that which is 'Kinda Queer Rabbit. Kills Kids at Freddy's' with like a bunch of triva about Bill thrown in there for good measure.

So yeh the rest is history, it gets put in the Help Wanted project to aid in development and ends up manipulating a bunch of the devs into doing awful things (and I think it is manipulation I kinda really dislike the possession angle) and it meets Vanny who's like... gotten SUPER into the Freddy's Murders after she started working for Faz Inc, so she agrees to do its bidding. For the most part that's 'what would William Afton do here' and 'Please get my physical body out of the hole'.

Yeh I think the Mimic is this really fun device for exploring cycle of abuse stuff and the legacy William leaves behind after his death- and how even though the guy himself is long burried the impact he's left on the people around him still festers and harms.
