No, Dragonball was just one long running story. It is full of plot holes, but it's because Toriyama never had an outline, and kept forgetting things he had done in past chapters. He actually created the Super Saiyan 3 form as Super Saiyan 2 because he forgot he'd already done 2, his editor had to correct him on that.Silentpony said:Wait I always thought DB was Japan's version of like Marvel or Dark Horse, in that its a bunch of alternate timelines/universes, what-if scenarios, one-shots, continuity reboots and the like. Declaring any one plot thread 'canon' is missing the point.
