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.
Obviously, Gohan and his sister are common characters. Goku might also be there as their father. Vegeta could be included too, as he is often part of the Dragon Ball storylines. Maybe Piccolo as well, since he has a connection to Gohan.
Well, in some Gohan's Little Sister fanfiction, she might play a crucial role in a big battle. For example, she could use her intelligence to outwit the enemies when the Z - fighters are in a tough spot. She might also have a special bond with a particular character that affects the course of the story, like an unlikely friendship with a villain who then has a change of heart because of her.
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.
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.
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.
