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.
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.
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.
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.
There were a few Dragon Ball Ascension System novels similar to the Ascension God Registration System that could be recommended. Among them were " Devouring the Starry Sky: Sign In to Become a God,"" Survival for All: 100 Times Cultivation Speed at the Beginning,"" Devouring the Starry Sky: Ask the Supreme,"" Battlefield of All Races: I Have a Billion Times Critical Hit System,"" Man in the King: Sign In to Become a God at the Beginning," and so on. These novels all used the Ascension System as the theme and combined the elements of the Dragon Ball to provide exciting and compact storylines.
Another great one is 'Dragon Ball Gods Meet Naruto's World'. This fanfiction explores what would happen if the gods from Dragon Ball entered Naruto's world. It's a unique take as it not only focuses on the battles but also on how the different cultures and powers interact. It delves deep into the lore of both series and creates a really engaging story.
One great Dragon Ball and Naruto fanfiction is 'The Ninja Saiyan'. It combines the unique powers of the Saiyans from Dragon Ball with the ninja skills in Naruto. The story follows a character who has the blood of both a Saiyan and a ninja, and his journey to master both powers and protect his world from new threats.
Another aspect to consider is how the Super Saiyan transformation would affect the relationships in the Naruto world. If Sasuke were to gain Super Saiyan powers, it could either drive him further away from Naruto due to the newfound power or bring them closer as they explore the new abilities together. Also, the concept of ki from Dragon Ball and chakra in Naruto could be merged, creating a whole new type of energy for the characters to utilize.
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.
