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.
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.
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.
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.
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.
Goku is often very popular. His naivete and pure heart would make for some interesting high school scenarios. He'd probably be the friendly jock type who is always eager to help out.
Maybe an evil scientist who has created a new form of bio - weaponry. He targets Gohan and Lime because they pose a threat to his plans of world domination. His creations could have abilities that are a challenge for Gohan and Lime to counter.
Vegeta is also popular. His prideful and brooding nature would be really interesting in a high school environment. He might be the loner who's secretly really powerful and has a soft spot for a certain girl at school.
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.
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 could simply avoid using his powers in front of others as much as possible. For instance, if there's a fight, he'd try to resolve it verbally instead of using his fists.
