I just made him last night so all of the Roy lore is a WIP and can change at any time but the gist is that due to living in some mythical place called """Nevada""", where a meteor had hit causing some kind of outbreak / chemical leak to affect the local population who didn't evacuate for the impact, he was horrifically mutated / injured and he simultaneously heals incredibly quickly but doesn't heal COMPLETELY, which leaves him consistently skinless or completely translucent (hence why he's always wrapped in bandages). The meteor has long since been cleaned up / quarantined, but due to a series of unfortunate events Roy just kinda lives like this with no aid or compensation so he's very lifeless and nihilistic. He isn't violent really but I'm sure he has a LOT of mental baggage to work through but he can't afford therapy because his insurance sucks!

So while I initially said "you probably can't fix him" you could at least fix him mentally I think? JUBHJK
