What about Slenderman? Are we allowed to make new pages, because that's what wikis are. Places where anyone can edit. Also, Slenderman isn't included in your canon, so I should add him, right? I think he should be a rival to John's family.
um you can do that but you have to make him like fighting john and his family your thing had nothing to do with anything just because it brought up slender,thats nothing do something like uh,(john the killer must fight slender) or something like that.
