Well, he would probably be a very different person. He might be more in tune with the Saiyan warrior culture. He could be more aggressive and less empathetic compared to the Goku we know. He would grow up learning the ways of the Saiyans on Planet Vegeta, which means he'd be trained to fight and conquer from a very young age.
In a 'Gohan Raised by Vegeta' fanfiction, Gohan's personality would likely change a great deal. Vegeta being his mentor would mean a strict and no - nonsense upbringing. Gohan would probably be more confident in his Saiyan heritage. His fighting style could be a blend of Vegeta's elegance in combat and his own natural potential. Also, the relationship between Gohan and other characters like Piccolo or Chi - Chi would be very different. With Vegeta's influence, he might be more rebellious against Chi - Chi's wishes for him to focus on academics.
His power would develop more in line with Saiyan traditions. He'd probably have a stronger base power due to the intense training environment on Planet Vegeta. There would be more emphasis on raw power and combat skills from a young age.
Well, it would be really strange and interesting. Vegeta is from Dragon Ball, a very different universe from Harry Potter's. If Harry was raised by Vegeta, he might be trained in combat from a very young age, like how Vegeta trains Trunks. He could be more aggressive and less reliant on magic wands, perhaps using his ki powers instead. And his attitude towards enemies would be more like Vegeta's, full of pride and determination.
One possible plot twist could be that Gohan becomes more powerful than Vegeta much earlier than expected. This would create an interesting dynamic as Vegeta would have to deal with his student surpassing him. Another could be that Gohan discovers a new Saiyan ability that Vegeta was unaware of, which could change their relationship and how they approach training.
He would likely have enhanced physical strength and speed, similar to Saiyans. Maybe he could fly like them too. His combat skills would be more brutal and direct, rather than the ninja - style he has in the original. He might also develop some sort of energy blast ability like Vegeta's Galick Gun.
Harry would probably be more aggressive in his personality. Vegeta's Saiyan nature is often associated with a certain level of aggression and competitiveness. So, Harry might show these traits more, not shying away from a fight and always striving to be the best in any magical situation.
There could be a fanfiction that focuses on the relationship between Tarble and Gure. It could show how they met and how their bond developed over time. For example, it might start with their first encounter on Planet Vegeta, where they were both young Saiyans training. As they grew up, they supported each other through various challenges and became very close friends or even more.
If raised by Vegeta, Harry Potter's character would undergo a significant transformation. He would grow up with a strict training regime, which would make him physically and mentally tough. His sense of justice would be more like Vegeta's, where he believes in power as a means to protect the weak. He would also have a different view of friendship. Instead of relying solely on emotional support from friends, he would expect them to be strong allies in battle. His development would be shaped by Vegeta's no - nonsense attitude and his determination to be the best.
A great one is 'The Adventures of Tarble and Gure'. In this fanfiction, Tarble and Gure are on a quest to find a lost Saiyan artifact. It's full of action as they face off against different villains who also want the artifact. The story also delves into their characters, showing Tarble's kind heart and Gure's fierce determination.
