Well, it could start with Gohan exploring a new area near his home and stumbling upon a strange artifact. This artifact could be something related to the Saiyan history. As he investigates it, he starts to have strange visions that give him clues about a hidden power or an upcoming threat.
Perhaps the fanfic could be about Gohan making new friends at school who are also interested in martial arts. They start their own little club, but then they accidentally attract the attention of some bad guys. Gohan then has to use his Saiyan skills to protect his new friends, all while still trying to act like a normal 10 - year - old boy in front of his family and teachers.
Another idea for the fanfic could be Gohan trying to balance his normal school life with his Saiyan heritage. He could be dealing with bullies at school while also hiding his true strength, and then one day he has to use it to protect his friends.
The plot could involve Gohan being the last hope against an all - powerful villain who has already defeated Goku and Vegeta. With Ultra Instinct, Gohan enters the fray. He starts by using his new power to dodge the villain's attacks with ease, surprising everyone. As the battle intensifies, he taps deeper into Ultra Instinct, unleashing attacks that the villain has never seen before.
One possible plot could be that Gohan somehow gets transported to Equestria. He might initially be confused by the magical and pony - filled world. Then, he could use his martial arts skills to protect the ponies from a new threat that they are unable to handle with their own magic. For example, a powerful dark magic - based villain arrives, and Gohan's strength and fighting techniques become crucial in the battle to save Equestria.
In this fanfic, Gohan might encounter different versions of his friends and enemies. He could see how the future has been shaped by past events. Maybe he meets a future version of himself who has become much stronger or has different values.
The plot could involve the baby's first days at school. It might be bullied because of its different heritage, but then shows amazing powers and earns the respect of classmates. This would be a simple yet engaging plot that shows the baby's growth and how it fits into the Dragon Ball Z world.
A fanfic I really like is 'Gohan, Goten and the Next Generation'. It not only features Gohan and Goten but also shows how they are training the next generation of fighters. It has a great plot that involves time - travel elements, where they go back in time to learn from the old masters and bring back those skills to their present time to train the young ones.
They could team up to invent something amazing. Bulma has the brains and Gohan has the power and knowledge of the Saiyan abilities. Maybe they create a new type of energy shield that can protect the whole planet from any kind of attack.
Well, for one, it's the character development. Seeing how Gohan and Goten grow as fighters and as people. For example, if a fanfic shows Gohan teaching Goten some new techniques, it's really engaging. Also, new adventures that are different from the original series are cool. Maybe they go on a quest in a new planet or something.
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.
He might meet Future Trunks. Since Trunks is often associated with the future in Dragon Ball Z, it's very likely they'll cross paths.
