These are slight design differences. It's like saying that because they using different colors from the manga, they can't be in the same continuity, even though the colors in the manga are inconsistent. The reason that they use anime designs & colors is because this is an anime, but this doesn't mean that the story of the movie couldn't have happened in the manga continuity.hleV wrote:Piccolo with 4 fingers and Piccolo with 5 fingers cannot be in the same continuity.
BUT, just because Toriyama wrote the new movies doesn't necessarily make it "canon". Kishimoto (Naruto), Oda (One Piece), Kubo (Bleach), and Sumimoto (Toriko), for example, have all written at least one movie, but most of them are non-canon to the manga (and some even to the anime), because they don't fit in the continuity. Kubo has even wrote the story of a video game, yet it doesn't even fit in the anime continuity.
