A "universal fanon" page is one that has no specific member's ownership-and can be edited by the community freely, with occasional exceptions. Most of the time, this is because no user can claim ownership of it-This being the case with canonical characters from Invader Zim, or crossover characters from other pieces of media. A canonical can be edited freely by anyone, but information should not be crudely removed-and a crossover character can be edited without removing or altering the original information.
Another form of "Universal Fanon" pages is if the community creates a character, object, or thing together-As such, no one person can claim ownership. In this case, the page can be edited freely, but such edits can be dissaproved the general community.
