This is spelled "cannon". Do not mix up the terms.


Canon is a term used to designate what is considered "official" in a certain fictional universe. With few possible exceptions only canon material is featured in the character pages. Non-canon material doesn't count - it never happened.

The generally agreed-upon definition is that the work by the original author and creator of the fictional setting is canon, unless the author or the copyright holder declares otherwise. Few other exceptions are also possible and should be noted on the verse page.

The primary canon is the source material first released (with few possible exceptions), with the other author works being secondary canon.

When different source materials give different versions of the same feat, and by that they contradict each other in the depiction of the feat, the primary canon takes precedence over the secondary canon.

If the feat is correctly depicted over multiple canons any of these can be used to judge the feat. Should by judging the feat through multiple canons different results be reached the result of the primary canon will have priority.

So for most manga series, that means the original manga is canon, while the anime is not (since the anime is simply an adaptation of the manga made by others). Databooks are considered secondary canon since scans tend to contradict them. It should be noted that this is often evaluated on a case - by - case basis.

For media that only provide descriptions through text (books, light novels, etc.), some special regulations are agreed upon, due to that feats in them are harder to judge given the nature of such text-based media. The special regulations are as follows:

  • For such media, a tertiary canon will be allowed. The tertiary canon consists of works not overseen by the author, which do not modify or contradict source material. When other source materials give different versions of the same feat and by that contradict the tertiary canon in the depiction of the feat the others take precedence. And here as well, if the feat is correctly depicted over multiple canons any of these can be used to judge the feat. Should by judging the feat through primary or secondary canon a different result be reached then for tertiary canon the result of primary or secondary canon will have priority.
  • Entirely new feats of tertiary canon, like for example new abilities, should be disregarded. Details added to existing fight scenes, such as damage caused to the surroundings, can be accepted.
  • Furthermore any changes based on tertiary canon will only be accepted if they are not contradicted by any instances of another canon, with regards to either the character power-scale, or logical inconsistencies (and plot holes).

In addition, as long as a feat from the primary and the secondary canon are displayed in the exact same way, utilization of timeframes displayed in a media that is considered secondary canon (such as an anime adaptation of a feat displayed in a manga) will be allowed for analysis and calculations. All of the rules that are written in the Cinematic Time page still apply when it comes to evaluation of such secondary canon feats.
