Non-Canon

What is filler?
Filler is extra things added ontop of the orginal storyline, database and characters.

The fiuller can take the form of:


 * A Game
 * A Movies
 * A Special episode made for the show
 * An extra storyline made for the show as part of it

How do fillers work in One Piece?
In anime they are there to fill out a series when the anime cataches up in storyline to the manga. The reason why it catches up is that the anime may contain up to three chapters from the manga during any one episode. Since the manga comes out weekly it creates problems - the anime is not allowed to get ahead of the manga at any one point.

In One Piece, they take form of:


 * History on the characters that nevered featured in the manga.
 * Fight scenes taking longer then they did in the manga.
 * Extra storylines that were no part of the orginal storyline whats so ever.

Usually with One Piece, many of the characters are designed by Oda himself. Some of the stories, such as the Logue Town arc Fillers, were ones Oda himself wanted to include in the manga, but didn't to move the storyline along faster.

Is Filler treated the same as Cannon?
Yes and no. Filler information is not always correct.


 * For instance, Chopper ate many Rumble Balls during the filler Davy Fights, but in the manga it was stated he could not eat 3 without it causing problems.


 * Another example would be Zoro stating he could cut anything during the Warship Island Arc, yet during the Alabasta Arc, he statd he could not cut steal.

Basically, if you must write Filler information, outside of a page note, you must back it up with evidence from the cannon that it is true to the storyline. The most common treatement of Filler Information is to write (Note: Anime Only) in one form or another to signify it is not canon. Filler information can end up being treated as speculation, if not handled correctly so it is advisable to take time thinking about how to approach it when including it on a page.
