In fanfiction, the scenario of Naruto being the son of Gohan and Videl could be a result of a time - travel or alternate dimension concept. Imagine a situation where Naruto somehow travels to a dimension where the Dragon Ball characters exist. Due to some unforeseen circumstances, he gets adopted by Gohan and Videl. This would lead to a whole new set of adventures for Naruto. He would have to adapt to the Dragon Ball world's rules, like the ki energy system instead of chakra. And his relationships with other characters like Goku and Vegeta would be very different from what he's used to in his own world.
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.
One possible reason could be that Videl does something that endangers herself. Gohan, being protective, might get angry out of fear for her safety. For example, if she recklessly jumps into a fight without proper training or preparation.
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.
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.
Another plotline might involve a slow - burn relationship. They could be friends for a long time, and as their bond deepens, there could be a scene where Videl finally decides to take the step and kisses Gohan. This could be after a series of events that make her realize her true feelings for him, like seeing him in danger and realizing how much he means to her.
One possibility could be a story about their training together. Videl is a strong fighter, and with Gohan's Saiyan power, they could have amazing adventures while sparring and learning new techniques. Maybe they discover a new threat to the Earth and have to combine their skills to defeat it.
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.
Their relationship can be developed by having them face challenges together. For example, when dealing with the monster, they have to rely on each other's strengths. Gohan's power and Videl's intelligence can complement each other. They can also have heart - to - heart conversations during their battles or while preparing for them, which deepens their bond.
A possible plot twist could be that Videl turns out to have some hidden powers herself. It would completely change the dynamic between her and Gohan.
Perhaps they go on a family trip. During the trip, Pan might see something amazing like a rare animal or a beautiful waterfall. She'd run to tell Gohan and Videl, and they'd all share in the joy of the discovery. They could also have conversations around the campfire at night, with Pan asking about their past adventures and Gohan and Videl happily sharing their stories.
Maybe in the fanfiction, Gohan could hate Videl because she's too overbearing. She's a strong - willed character and might push Gohan in ways he doesn't like.
