But there isnt an official canon. Every reference to canon that is ever mentioned, is invented by fans. Toriyama himself never states what is official Canon. The closest he comes is referencing his Manga as the main story and some non-Manga content (like movies) as being side-stories but that is not the same as establishing an official canon. Ultimately I feel like the people who take whats canon so seriously are just missing the point of dragon ball. I dont think Toriyama or Toei would want fans to get caught up over whats official and whats not. Even in cases where theres obvious discrepancies (like certain movies taking place during timelines that dont fit in with the main stories) its still all dragon ball and they just want the fans to enjoy the content whether its Manga, anime, movies, side-stories, etc all the same.
