>>280522787Generally, a lot of works that have canon debates are works that don't really have what one could call a "canon" in the more common western sense.
For example, you'll see this a lot with Dragon Ball. The following were all written by Toriyama, thus, theoretically, making them canon:
>Dragon Ball (manga)>Neko Majin (manga)>Dragon Ball: Yo! Son Goku and His Friends Return (OVA)>Dragon Ball Online (Game, Setting and Timeline)>The Galactic Patrolman Trilogy (Manga)>Dragon Ball Minus (Manga)>Dragon Ball: Kami to Kami (Movie)>Dragon Ball: Fukkatsu no F (Movie)>Dragon Ball Super (Anime)>Dragon Ball Super (Manga)>Dragon Ball Super: Broly & Super Hero (Movies)>Dragon Ball Daima (Anime)Now, if you're familiar with DB, you'll realize something.
This doesn't work.
Neko Majin has Vegeta working for Freeza but it's set after End of Z.
Dragon Ball Online gives a full timeline of events that absolutely does not work with later stories.
Dragon Ball Super's anime and manga are contradictory to each other constantly, and also contradict the two movies that started that phase of Dragon Ball.
And Dragon Ball Daima was recently infamous for introducing a new transformation that Goku always had and could access, before the events of Dragon Ball Super.
This isn't even going into how Toei made an official timeline that goes
>Dragon Ball>Dragon Ball Z>Dragon Ball Super>Dragon Ball GTOr how titles spinning off of Online just say "EVERYTHING is canon", or that GT includes references to the Z films, or that the Dragon Ball Super anime includes a contradiction from DBZ Movie 4 that is disproven by the Boo arc, and so on and so on.
But yeah, canon doesn't really matter for a lot of stuff. It can matter, but if you're looking at franchises it usually doesn't unless they're really western influenced (big one in that regard is Resident Evil, which has 30 years of history where it tries to maintain the idea that everything is one storyline).
