Well, Naruto joining the Z Fighters would mean a lot of cultural exchange too. Naruto comes from a world with a complex ninja society, and the Z Fighters are from a more science - fiction - like world. Naruto might introduce concepts like chakra control and different ninja clans to the Z Fighters. And the Z Fighters could show Naruto their advanced technology and spaceships. In terms of battles, Naruto's shadow clone jutsu could be used to confuse enemies, while the Z Fighters' super - fast punches and kicks would be a new sight for Naruto. They could learn from each other and become even stronger as a team.
The other Z - fighters will surely feel his absence. Vegeta, for example, might be frustrated. He was always in competition with Goku and Gohan's power. Now that Gohan has left, he might feel like there's no one worthy to compete against. Piccolo, who has a special bond with Gohan, will be worried. He'll probably go looking for Gohan at some point, fearing that something bad has happened to him.
Naruto's chakra - based powers would contrast with the ki - based powers of the Z Fighters. His Rasengan, which is a concentrated form of chakra, could potentially be combined with the energy blasts of the Z Fighters. For example, Goku could add his ki to Naruto's Rasengan to create an even more powerful attack. Also, Naruto's ability to transform, like his Nine - Tails Chakra Mode, would give him an edge in terms of raw power and speed, which could be on par with some of the Super Saiyan forms of the Z Fighters.
In a crossover with the Avengers, Iron Man could be an ally. His high - tech gadgets combined with Gohan's power would be a great team. Also in the Pokémon world, Ash could be an ally. Ash's knowledge of Pokémon and Gohan's combat skills could be useful. In the Bleach universe, Ichigo could be a strong ally for Gohan, with their combined sword - fighting and energy - blasting abilities.
One possible fanfiction could be about Bulma helping Gohan with his studies. Since Bulma is super smart, she could tutor Gohan in advanced science and technology. This would not only strengthen their friendship but also give Gohan new knowledge that might come in handy during his battles. For example, understanding the principles of energy and mechanics could help him better strategize against his enemies.
Gohan will most likely encounter other Z - fighters like Krillin and Tien. They were all part of the group back then. Also, there's a good chance he'll meet Master Roshi. Roshi was a key figure in Goku's training, so his interaction with Gohan could be really interesting. He might also come across Bulma, who was always involved in the Dragon Ball story, either by accident or because he needs her help with some time - related technology or something.
In some Dragon Ball Z fanfiction where Gohan is neglected, it might explore how he copes with the lack of attention. Maybe he turns to self - training more intensely. He could also form unexpected friendships with other characters who notice his isolation.
In a fanfiction, Gohan as Super Saiyan 3 could be involved in a time - travel adventure. He travels back to a crucial point in Dragon Ball Z history and has to use his Super Saiyan 3 powers to change certain events. This could lead to a whole new timeline where things are different. For example, he might be able to prevent the destruction of Planet Namek or save some characters who originally died.
