What is filler?
Filler is extra things added into the original storyline, database and characters.

The filler can take the form of:
 * A Game
 * A Movie
 * A Special episode made for TV
 * An extra storyline made for the show as part of it

How do fillers work in One Piece?
In anime, fillers are there to fill out a series when the anime catches up in storyline to the manga. Anime can easily catch up to the manga because a single anime episode can cover more than one manga chapter. Since the One Piece manga comes out weekly, this creates problems; the anime cannot get ahead of the manga at any one point.

In One Piece, fillers take form of:


 * History on the characters that were never featured in the manga.
 * Scenes taking longer then they did in the manga.
 * Extra storylines that were not part of the original storyline.

In One Piece, unlike in many series, 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 in order to move the storyline along faster.

Did Oda have any part?
Despite the fact that the characters are only in the anime, Oda designed many of them for Toei (anime) and Bandai (video games).


 * There is a Louge Town novel Oda wrote in 2000 containing the stories Oda never published in the normal storyline. The characters Daddy the Father, Alice, and Carmen are not entirely fillers.

Is Filler treated the same as Canon?
Filler information is not always correct so it is somewhat treated differently.


 * Chopper ate many Rumble Balls during the filler Davy Back Fights, but in the manga it was stated he could not eat 3 without it causing problems.
 * Zoro stated he could cut anything during the Warship Island Arc, yet during the Arabasta Arc, he stated that he could not cut steel.
 * In the anime, Coby and Helmeppo went through the Reverse Mountain, but in the manga, they went through the Calm Belt

If filler information is to be included on a page, it needs to be treated appropriately. Simply writing (Note: Anime Only) is appropriate handling of the information. Filler information may be treated as speculation if not handled correctly, so it is advised that you take time thinking about how to approach it before including it on a page.
