The story length of Super Dragon Ball Heroes World Mission varies depending on how quickly you progress and explore all the content. But generally, it can offer several hours of gameplay and story.
Well, some fanfictions might focus on a time - travel scenario involving Gohan and Zamasu. For instance, Gohan travels back in time to prevent Zamasu from becoming the evil entity he is in the main storyline. This could lead to a whole new series of events where Gohan has to convince the earlier version of Zamasu to choose a different path. It could be filled with intense battles, moral dilemmas, and character development for both.
In 'Super Dragon Ball Heroes Top Stories', there are new forms and power - ups introduced. These not only make the battles more exciting but also add depth to the characters' development. For example, some characters might gain new abilities that change the course of a fight completely. It's a great addition for fans who love to see the characters evolve.
Well, it depends on how you define fanfiction. Technically, Dragon Ball Super is an official continuation of the Dragon Ball series. However, it does have elements that feel like fanfiction. For example, some of the power - levels and new forms introduced seem a bit outlandish and more like what a passionate fan might come up with rather than a strictly logical progression from the original story. But it's still an official part of the franchise so it's a bit of a gray area.
