I think we should start classifying Dragon Ball canon by continuities, because with the various continuity errors and constant reclassification of what's canon and what's not every time something new is released is ridiculous. It could be handled the way Yugioh Wiki handles the various continuities, or at least make tabs for conflicting information. Here's some examples of how I envision the article option:
Goku (Manga) would cover Goku's appearances in manga versions of DB, DBZ and DBS, as well as information that applies only to Goku in the Manga.
Goku (Anime) would cover the Goku that appeared in Dragon Ball, Dragon Ball Z, and Dragon Ball GT Animes, as well as information that only applies to this version of Goku.
Goku (Super) would cover the Goku that appeared in Dragon Ball, Dragon Ball Z Kai, and Dragon Ball Super Animes, as well as information that only applies to this version of Goku.
And so on and so forth. If anyone has any suggestions or better ideas, go ahead, i'm just spitballing here.
