Regarding the canon: In terms of canon material, this wiki deems the manga as the primary canon.
The anime is considered secondary canon on a case by case basis. In the case of anime, it contradicts statements, feats, personalities, and abilities of characters in many cases. This happens with censorship, filler content in canon material, and pacing. Since we have confirmation that Oda approves certain scenes in the anime, we've decided to take the anime as canon in the areas where it perfectly or similarly represents the manga, and the scenes not shown in the manga that are represented in the anime will be deemed as filler. It was decided
in this thread.
- Please note, the anime is not allowed to be used if the manga gives a perfect alternative for a feat. For example, the shockwave caused by Luffy and Doflamingo's clash was not shown in the manga, and should not be used to scale the manga characters. The anime is mainly used for timeframes, clarifications for feats, etc. If the manga is clear enough, the anime should not be used.
