Canon

What is Canon?
Whenever an author writes a series, everything he or she wrote themselves is considered canon. To put it more simply, canon is the original material that was stated by the writer in their work.

One Piece Canon
To know the story of One Piece and it's content, you must look towards the Japanese print of the manga; where the series started from. The manga is the backbone of the One Piece materials, without it, One Piece wouldn't exist.

When is something not Canon?
If an offical source, say a writer from Toei, decides to write a story based on Eiichiro Oda's work, then its Filler. This includes movies, the t.v. specials, video games, and anime fillers are non-canon.


 * An example - In the manga, Ace met with Luffy and his crews briefly in Alabasta. After this Ace destroyed the Billion's ship and left. In the anime, Ace stayed on with the Straw Hats until just before they arrived at Yuba.

If an unoffical source, say a fan of One Piece, decides to write a story based on Eiichiro Oda's work, then its Fanfiction or as some call it "Fanon".


 * An example -In the manga; Vivi was the princess of Alabasta, that's canon because that is how the writer stated it. If you say that Vivi was a martian queen, that's considred fanfiction because Eiichiro Oda did not write Vivi to be an martian queen.
