If I'm the creator of two characters and decide to write out a bunch of information about what would happen in various, ship related, scenarios between the two characters, but the characters aren't together in canon, what are they called? 

Are they canons because the creator came up with them and would happen if their relationship went canon? 

Or are they headcanons because the scenarios aren't (yet) canon and in some cases could not happen within the canon? 

This is a pressing matter that I do not need help with regarding the fates of two of my characters I totally don't ship together. 

Totally don't ship them nope.
