Well, it could be about many things. Maybe it's about Gohan's adventures that the author has imagined, like his training in new and unique ways, or his relationships with other characters in a different light. It might also focus on Gohan's daily life, his struggles in school while also being a Saiyan warrior, things like that.
Well, it could be really exciting. Gohan has his Saiyan powers like super strength and flight. In the My Hero Academia world, he'd probably be seen as an extremely powerful hero. His fighting skills and his ability to sense danger would make him a top - tier hero. He might not even need a quirk, or his Saiyan powers could be considered some sort of super - quirk. He could also train the students at U.A. to become stronger.
When writing a Goku and Gohan fanfiction, it's important to keep their relationship in mind. Their father - son bond is a key aspect. You could start with a situation that challenges this bond, for example, a misunderstanding between them. Then, as the story progresses, they work through it and come out stronger. Also, don't be afraid to borrow elements from the original series but put your own spin on them. For example, you could rewrite a famous battle from Goku and Gohan's perspective in a different way.
First, know Gohan's character well. Think about his strengths like his Saiyan power and his intelligence. Then, create a cool and challenging situation for him, like a new super - villain he has to face. For example, you could make the villain have a unique power that forces Gohan to think outside the box. Also, don't be afraid to give Gohan some new moves or abilities. Just make sure they fit his character.
Well, it could be really interesting. Gohan, with his Saiyan powers, would be quite a unique addition to the My Hero Academia world. In a harem situation, he might attract various female characters from MHA. Maybe his strong sense of justice and his power would make him a popular figure among them. He could potentially form relationships with characters like Ochaco, who has a kind heart and might be drawn to Gohan's good nature.
His return could have a huge impact on the power balance. Since Future Gohan is a powerful fighter, his presence could tip the scales in battles against villains. For example, in fights against the Saiyans or the androids, his skills and experience could give the Z - fighters an edge.
In this fanfiction, Gohan might learn valuable life lessons from Grandpa Gohan. Maybe Grandpa Gohan would teach Gohan some old - fashioned martial arts techniques that have been forgotten over time.
In such a fanfiction, perhaps future Gohan could warn present - day Gohan about upcoming threats that he has faced in his own timeline. He might share his experiences and knowledge, which could make present Gohan a stronger fighter and a wiser person.
Piccolo might also be a savior. He has a soft spot for Gohan since they trained together. He could use his strategic mind and powerful attacks to outwit Raditz and rescue Gohan. Maybe he teams up with Goku for an even more epic rescue mission.
