OH MY GOOOOOOOOOOOOOOD!
Yeah, hi, Defunct Fredbear is finally finished! God damn, this was painful. This skin has gone through at least three versions in the last two weeks, it's frankly ridiculous how many times I chose to redo him. But I finally settled on this old, withered, and neglected design reflecting likely how people would have felt at the time about Fredbear. People would have wanted him gone, blended in with the ruins of the Fredbears brand, and that's exactly what this skin feels like to me, pardon the blood on the jaw.
My idea for him more or less is that he's been sitting, decaying and infinitely neglected, outside Fredbears for years now, sitting in the rain, snow, sleet, hail, heatwaves, floods, and burning sunlight. All of this culminating him a faded rotten- almost brown look covered in dirt, dust, grime, and whatever else you can think of and barely functioning missing pieces and rusting to oblivion. With his jaw likely stuck exactly as it was left on the day of the bite, as his endo has likely been damaged beyond repair at this rate, he just lingers there, waiting.
This also serves as essentially my headcanon idea for that FNaF 3 Shadow Freddy easter-egg as well as golden Freddys appearance in FNaF 2, I'd imagine people would have seen him from time to time sitting back there in the alleyway behind Fredbears, likely resulting in the various hallucinations of him throughout the various Fazbear establishments each taking different aspects. FNaF 2 features the bulky-ish design and missing ear, FNaF 1 featuring the clearly broken jaw and style of FNaF 1 Freddy, and FNaF 3 taking- basically his whole design with a more FNaF 2 feeling and making it a literal shadow of his former self.
Anyway, all that being said, enjoy this pain in the ass of a skin as well as its variants (Including the base withered version with no staining in case y'all want to edit a version for yourself and your roleplays)

Phantom Shadow Freddy variant:


Customizable variant:
Note, when using the custom variant its recommended that you do most color edits in getpaint.net for convenience and accuracy to the base skin, as well feel free to dm me a few images of your edits (Since my content guidelines state that you can not post my work unless explicitly stated otherwise) if 'ya like, I'd love to see 'em!
