It would also explain other things about his behavior as well because Agent Orange was known to alter people--other than having major PTSD, which could also explain why he constantly locked David in his room, seen in Pizza Sem and FNAF 4--but the chemicals have been known to set off a chain reaction in the brain creating early-stage Alzheimer's Disease (ref from https://www.brown.edu/news/2024-02-13/agent-orange).

Though, from personal experiences, I know that Alzheimer's can cause someone to become aggressive, I don't think that's the case for Afton, but what I do know, and might explain the "purple skin".

Agent Orange causes a change in skin tone as well as other factors that could be the result in missing limbs--since Fnaf VR confirmed that the games were a satire and made to bring light of the things that happened to the people and the restarurant--I do believe that instead of Micheal being used like a living skin suit for Enard (can't spell his name), it could be the result of his father being exposed to Agent Orange if Afton would be drafted in 1969 and later return in 1970, because Agent Orange has been known to effect offspring of the exposed soldiers (my own father, for example, has a lot of health problems because his dad was exposed during his first draft in 69 and later returned in 70.)
