There could be such a fanfiction. The world of fan - created content is full of surprises. Writers might be inspired to give Naruto the power of Hamon for several reasons. It could be to create a more complex power system in the Naruto world, or perhaps to introduce a new type of threat that only Hamon can counter. Maybe they want to see how Naruto's friends and foes would react to this new ability. So, while I can't say for sure, it's very likely that it exists out there in the sea of fanfiction.
The JJBA manga is indeed finished. It had a great journey and wrapped up with a satisfying conclusion for fans. However, there's always the possibility of spin-offs or related works in the future.
In a 'Naruto has Hamon' fanfiction, Naruto would likely have a new way to interact with his enemies. Hamon, being a life - energy based power, could give Naruto an edge in close - combat situations. He might discover that some of the chakra - based creatures in his world are vulnerable to Hamon. Also, his relationships with characters like Sasuke could be affected as they try to understand and adapt to this new power of his. The story could explore how Naruto uses Hamon to bring about peace in the ninja world in a different way than just with his regular ninja skills.
A group of power - hungry individuals who see Naruto as a threat to their plans of using Hamon to take over the world. They would constantly send assassins and create obstacles for Naruto.
One idea could be Naruto learning Hamon techniques and using them in his battles against powerful foes. For example, he could combine his chakra with Hamon to create unique attacks.
Well, 'jjba visual novel' is likely related to the 'JoJo's Bizarre Adventure' series in a visual novel format. It probably features the unique characters, their stands, and the wild storylines from the original work. You can expect lots of character interactions, decision - making elements that might affect the story, and of course, the over - the - top and creative art style that the 'JoJo's Bizarre Adventure' is known for.
There's also 'Diamond in the Rough'. This fanfic focuses on a unique relationship between the reader and a JJBA character. The writing style is very descriptive, especially when it comes to the Stand battles. It really brings the action to life and makes you feel like you're in the middle of the chaos.
Some JJBA fanfics that are worth reading are the ones that expand on the battles. They might add more complex strategies or new foes that the characters have to face. For instance, a fanfic could introduce a new stand user who has the power to manipulate time in a different way than Dio. Also, fanfics that give a different perspective on the existing story arcs, like seeing the events of Stardust Crusaders from an enemy's point of view, can be quite engaging.
