In SSR as we know Withered Bonnie is one of the survivours and stays with the group for most of the movie until the point after Godzilla comes along and the big fight starts. He is just gone, never brought up again like he was erased from existence. He isn't even in the end credits (Go and Look) or in the epilouge. This got me thinking where he went, then I remembered the Behind the Scenes about the mystery character. Everything was Torn away from him mentally and physically and that it was someone that we know.

(I know this part is a lose thread, I couldn't find any more point to make here.) I have points about these for mentally is a few points that I found when rewatching the specials. In the St. Partricks day 1. Withered Bonnie was drinking beer but when he ran out he threw the bottle for no good reason. There is also a point in SSR that strengthens this theory. When Ennard find him he say's "I already lost my face, why make me suffer more". He is sad. He had his happiness mentally ripped away from him.

For physically he had his friend ripped away. The people he felt the best around. He was erased from there heads. so even if he did come back they wouldn't know who he is. He must have been taken by The_End or captured by Glitchtrap to bring to The_End. Maybe he did the sam thing chica did with the button be he pressed it or something.

We obviouslly know Withered Bonnie, I don't need to go further.

I just came up with this a few months ago and decided to share it.
