According to my current knowledge, there is no official sequels or extras for the God and God of the Dragon Ball. Although some people claimed to have seen a work similar to the sequels, the officials did not give any relevant information or confirmation. If you want to know more about the Dragon Ball God and God, it is recommended to read related novels or comics, or consult the author or bookstore.
Yes, it is quite popular. It delves deep into aspects of the Dragon Ball universe that other parts of the series might not have explored as thoroughly. It offers new storylines and character developments related to the concept of 'God Mu', which attracts many fans of the Dragon Ball franchise.
In the Dragon Ball novel, the Saiyan race doesn't really have a specific 'God of Saiyans' in a traditional sense. However, some might consider characters like King Vegeta to have a kind of god - like status among the Saiyans due to his leadership position.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for the relevant tags like 'Dragon Ball', 'God', and 'Naruto' and you'll find a variety of stories that combine elements from these different series in interesting ways.
Power - ups are a common theme. For example, a Naruto character getting the power of a Dragon Ball god. Another theme is crossovers, like the characters from both universes meeting. And sometimes, there's the theme of exploring different power systems. Naruto's chakra system compared to Dragon Ball's ki.
One of the main themes is power and its limits. The concept of God Mu and his powers are explored, showing how far a being can go in terms of strength. Another theme could be destiny, as the characters' paths seem to be intertwined with the overall fate of the Dragon Ball universe.
The plot might involve the new God of Destruction facing a powerful threat that even the other Gods of Destruction can't handle. He has to gather the strength of all the Saiyans and other allies in the Dragon Ball universe. This could lead to new power - ups for characters like Goku and Vegeta as they train to fight alongside the new God.
The crossovers of characters are also fascinating. Seeing Naruto interact with Goku, Vegeta, or other Dragon Ball characters, and vice versa, brings out new dynamics. For example, Naruto's strategic mind along with Goku's straightforward and powerful fighting style can lead to some unexpected and exciting storylines. Also, the fanfictions often explore how the different worlds and their rules collide and merge, which can be really engaging as it gives a fresh perspective on both Naruto and Dragon Ball universes. This exploration can range from how the different power systems work together to how the social and cultural aspects of each world interact.
One idea could be Gohan struggling to control the new power of the Super Saiyan God. He might accidentally cause some destruction while training and then have to deal with the guilt and the fear of his power getting out of control.
There are some fanfictions that explore the concept of a God-like being choosing Naruto and Goku from their respective universes for a special mission. This often involves them having to learn from each other's fighting styles and powers. For example, Naruto might learn how to control his chakra in a new way from the ki control in Dragon Ball, and Goku could gain something from Naruto's ninjutsu concepts.
