I don't think you should include GT in these kinds of things. It was not totally created by Toriyama, therefore, shouldn't be included. But as far as DBZ goes, you are missing Vegitto, who was the most powerful person of DBZ by the end of the Buu saga. NOt to mention that you forgot Kid Buu (unless I can't see him)
