In a 'naruto son of gohan fanfiction', perhaps Naruto is born with a special power that is a combination of his own ninja abilities and some latent power from being related to Gohan. This could lead to him being an outcast at first in the ninja world as his powers are so different. But as he grows, he learns to master them and use them to protect his village and the world from new threats.
Well, it could be about their son inheriting unique powers. Maybe he has a mix of Gohan's Saiyan abilities and Videl's human tenacity. He might start training at a very young age, much like Gohan did, and face challenges that test his limits both physically and mentally.
Naruto would likely have a very different life. He'd grow up in a world full of Saiyans and other Dragon Ball characters. Instead of learning ninjutsu, he might be trained in martial arts and ki control. His friends would probably be different too, like Goten and Trunks. And his goals might shift from becoming Hokage to perhaps protecting the Earth from otherworldly threats like in the Dragon Ball series.
It could be a new Saiyan from another part of the universe who is jealous of the power the family holds. He might come to Earth to challenge the son and prove his own superiority.
Her relationships with other characters would shape her differently. With Piccolo, he could act as more of a protective figure. Gohan, in turn, would learn different values from him. Maybe she would be more attuned to nature and use it to her advantage in battles, like Piccolo does, rather than just relying on brute strength.
I'm not aware of any such fanfiction. The relationship between Grandpa Gohan and Son Goku in the original story is one of love and mentorship, so this kind of dark and negative portrayal in fanfiction is not common that I know of.
In this fanfiction, Gohan as a girl could bring a new dynamic to her relationships. She might have a different kind of friendship with Videl. Instead of the typical male - female relationship they had before, it could be more of a sisterly bond where they support each other in different ways, like in fighting crime together in a more united front.
This idea is quite out - there in fanfiction. One way it could work is if there are some powerful deities or beings in both universes who decide to manipulate the fates of characters. They could use their powers to transplant Naruto's essence into a new world where Gohan and Videl exist and make them his parents. However, this would completely change Naruto's origin story and his character development would have to be re - imagined in the context of the Dragon Ball world, which has very different power systems and cultures compared to Naruto's world.
Perhaps Gohan's own overconfidence could lead to his death. He might underestimate an enemy's power or a dangerous situation and make a wrong move that results in his end. For example, he could rush into a fight without proper preparation thinking he can handle it easily.
Gohan's power of transformation could be affected. Instead of turning Super Saiyan in the normal way, it could be related to the haki system in One Piece. Maybe his Super Saiyan form gives him a special type of haki that is unique and extremely powerful.
