JapNation AniManga also reported that the Dragon Ball Z manga continuation would go back to its roots as an "adventure" story similar to the original series compared to the DBZ manga that focused too much on the battles and the "bad guy of the week" format. The story is rumored to be Goku, under the training of Whis and Bills would travel the DBZ multiverse in order to learn more about the "Super Saiyan God" form and why it exists. Of course, it is also rumored that the "main bad guy" of the manga would be the most powerful god of destruction who also happens to be THE Super Saiyan God.
