Well, he might use his powers secretly. Like, he could use his super speed to be on time for every class without even breaking a sweat. And when there's a bully in school, he could give them a little scare with his strength, but not too much to expose his true identity.
One possible scenario in this fanfiction is that Gohan's academic achievements in high school are off the charts. He's used to studying hard under Piccolo's tutelage. So, he aces all his tests. But then, there are these other students who are jealous of him. They try to find ways to bring him down. Meanwhile, Gohan is also dealing with the fact that there could be some evil forces lurking around the school, attracted by his power. He has to protect his classmates without them knowing his true capabilities.
In the fanfiction, Gohan going to high school could lead to some really interesting relationships. He might befriend the nerdy kids because he's smart too. And there could be a love interest. Maybe a girl who is intrigued by his mysterious side. He would have to balance his normal high school life with his Saiyan heritage, which could make for some really fun and tense moments. For example, during a school sports day, he has to hold back his super strength so as not to win too easily and draw attention.
In this fanfiction, Gohan might face the challenge of hiding his Saiyan powers from his classmates. He could also make new friends who are interested in different things like academics or sports, and he has to balance his high school life with his training as a Saiyan warrior.
Obviously, Gohan would be the main character. Videl could also be in it as a classmate or a potential love interest. Piccolo might keep an eye on Gohan from afar to make sure he doesn't get into too much trouble. And of course, Gohan's friends from previous adventures could make cameo appearances, like Krillin dropping by the school sometimes.
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.
One interesting plot could be Gohan trying to balance his Saiyan powers with high school life. For example, he might accidentally use his super strength during gym class and have to cover it up.
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.
Often, his friends at high school can be important characters too. They might be normal humans who are curious about Gohan's sometimes strange behavior. And of course, his family members like Chi - Chi could make appearances, maybe giving Gohan advice on how to balance school and home life.
Another thing that could occur is that he might accidentally create new threats. By interfering with the past, he could disrupt the natural flow of events and cause new villains to emerge or existing ones to become more powerful in different ways. It's a risky move going back in time, even in fanfiction.
When Gohan's class meets Goku in fanfiction, there are numerous possibilities. Goku could be invited to talk about his adventures across different planets. His tales of fighting powerful foes like Frieza and Cell would be fascinating to the students. Maybe he'd even bring out some of the Dragon Balls as a show - and - tell item. This would not only shock Gohan's classmates but also make them realize the vastness of the Dragon Ball universe. Goku could also interact with Gohan in a different way in front of his class, showing a more father - son relationship than what they usually see in the normal series.
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.
