If Gohan was a wolf in the fanfiction, his relationship with Chi - Chi would be really interesting. Chi - Chi might be overprotective at first, not wanting Gohan to use his wolf form because she's afraid of the unknown. But as she sees how it can help Gohan in battles and in protecting the family, she might become more accepting. His relationships with his classmates would also change. They might either idolize him for his cool new form or be afraid of him, which could lead to some drama at school.
Gohan's relationship with Vegeta would be complex. Vegeta, being proud of his Saiyan heritage, might initially view Gohan's wolf form as some sort of aberration. However, as he sees Gohan's power and how it can be used to fight against common enemies, he might begrudgingly accept it. Gohan's love life could also be affected. If he had a crush on someone, say Videl, she might be initially put off by his wolf form but then grow to love him for who he is on the inside as well as the new powers his form brings to the table.
His relationship with his father Goku might change. Goku would probably be both curious and a bit worried. He'd want to help Gohan understand and control his new form. With Piccolo, he might become more of an equal in terms of being an 'outsider' since Piccolo has always been different. And with his friends, they might be initially scared but then come to rely on his new wolf - enhanced abilities.
Gohan could become more of a leader. With the power of Super Saiyan 5, he would be one of the most powerful beings in the universe. Other Z - fighters might look to him for guidance and leadership. This could bring out a more assertive side of his personality. He would need to step up and make tough decisions for the greater good, which would shape his personality in a more authoritative way.
In fanfiction, Gohan could have an encounter with a wolf in many ways. Maybe the wolf is a magical or mutated creature in a story where Gohan has to protect the forest it lives in from some greater evil. The wolf could also be a spirit guide of sorts, leading Gohan to a new power or a hidden place full of secrets.
His relationship with Vegeta would also change. If Goku goes back to a time when they first met, he could try to befriend Vegeta right away instead of being enemies first. This would change the entire dynamic of their rivalry. They might become allies much sooner and train together, which would lead to both of them becoming even stronger at an earlier stage.
Gohan's powers would probably be seen as extremely strange and almost magical to the ponies. His ability to fly without wings, shoot energy blasts, and his super - strength would be beyond their comprehension. They might initially be frightened of him, thinking he's some kind of dangerous being. But once they see he's there to help, they would be in awe of his powers and see him as a powerful ally.
Gohan's relationships would develop differently. Let's say he goes back to when he was a kid and meets his father, Goku, at a younger age. He'd have a different kind of bond with him. He could teach Goku things he learned in the future, and this would change how they interact. Also, his relationship with Piccolo would be altered. He might be able to train with Piccolo in a more advanced way earlier, leading to a stronger bond based on mutual growth and respect. Overall, Gohan would become more of a proactive and influential character in the past.
One possible fanfiction idea could be that Gohan's sister discovers she has a unique power that no one else in the family has. Maybe she can communicate with animals in a way that helps the Z - fighters. For example, she could get information from the animals about the whereabouts of the next big threat to Earth.
They'd be shocked. Goku is a legend in the Dragon Ball world, so they'd be super excited and probably a bit scared too.
One great fanfiction could be about Gohan and Piccolo's training sessions. Gohan, with his Saiyan - human hybrid power, and Piccolo, the Namekian, could be exploring new ways to increase Gohan's power. Maybe they discover a new technique while sparring in the wilderness. This would not only strengthen their bond as mentor - student but also as friends who rely on each other in battles against stronger foes.
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.
One interesting storyline could be Gohan's struggle to control his wolf - like instincts while still being a Saiyan. Maybe he has new powers related to his wolf form that he has to learn to master. Another could be him facing off against enemies who are both intrigued and threatened by his unique form.
