I have many headcanons for Paper but not much to keep track of.
•He had a bad case of an e@t1ng d1s0rd3r (anorexia nervosa) and wasn’t able to eat much food at Hotel OJ but OJ noticed and tried to help him out by supporting him in ways.
•He was born a female but didn’t feel comfortable in a female body so once he left his parent’s house, he worked jobs to get enough money for top and bottom surgery.
•Because he was born female, he had a high voice but he tried making it more masculine, which he succeeded but was still left with a high male voice.
•His parents were very supportive of his transition and didn’t force him to do anything.
•Because of Evil Paper coming out when Idiotic Island was mentioned, OJ and Paper agreed that the word was banned from the hotel, so the hotel wouldn’t be destroyed.
That’s all but I might come up with more.
