Headcanon (or Personal Canon)

Headcanon (or Personal Canon) 

Refers to the personal beliefs or interpretations about canon that an author or reader makes to explain or account for some aspect of the actual canon. The headcanon itself, while not officially supported by the canon, tends also not to be actually disproven or refuted by the canon and will therefore seem plausible in the mind of the fan who imagines it. Headcanons are as many and varied as the fans themselves, may be about the past, present, or future of the character or plot, and can be shared by others if particularly enticing or believable. In fact, if a headcanon is so popular that it gets adopted by many members of a fandom, it may eventually become accepted as fanon for that fandom.
