Sometimes Goku can also be a main character in these fanfictions. His relationship with Bulma as a long - time friend and fellow Z - Fighter can be explored. And as a Saiyan, his different approach to being a Saiyan compared to Vegeta can create interesting dynamics, especially when Bulma is involved in the story.
Bulma and Vegeta are often the main characters. Vegeta, as a Saiyan, brings in the elements of Saiyan pride, power, and the drive to become stronger. Bulma, on the other hand, is the intelligent human who can often balance out Vegeta's more brash Saiyan tendencies with her rational thinking.
Obviously, Bulma and Saiyan characters like Vegeta are mainstays. Vegeta is often a central figure as his relationship with Bulma is a rich area to explore in fanfic. Goku can also be prominently featured, especially when it comes to his Saiyan nature and how Bulma interacts with him in different scenarios.
Hermione could also be a main character. In the fanfiction, she could be studying the connection between magic and Saiyan biology. She might use her intelligence to help Harry or other characters understand and control their Saiyan powers.
The main character is often the original character (oc) who is a saiyan. They usually have traits like super strength and a love for gaming.
Obviously, Deku is one of the main characters. Since it's a Saiyan Deku fanfiction, he is the one with Saiyan powers. Other characters from My Hero Academia like All Might or Bakugo can also be important characters in the story, as they interact with Deku in different ways because of his new Saiyan abilities.
Often, Goku or Vegeta are the main characters. Since they are well - known Saiyans in the Dragon Ball series. They are put into the gamer scenario, for example, Goku might be a novice at first in a new game but quickly learns and becomes a top player.
Most likely Naruto would be one of the main characters since it's in the title. And perhaps there could be other Naruto - verse characters like Sasuke or Sakura. Since it involves Saiyan elements, there might be some sort of Saiyan - like or Saiyan - inspired character created for the fanfiction.
Obviously, Harry would be the main character. Since it's about him being a Saiyan. And I think some of his friends from the Harry Potter series might also be important characters, like Hermione and Ron. They could react to Harry's new Saiyan identity in different ways.
Most likely Naruto himself would be a main character. Since it's a Naruto - related fanfiction, he'd probably be the one to first experience or be influenced by Saiyan pride. It could also include Sasuke, as he often plays a major role in Naruto stories. They might interact in new ways due to the addition of Saiyan - like elements.
Well, Naruto's Saiyan nature would mean he has a strong sense of pride and a love for fighting. When he meets Bulma, she might find his fighting - loving side a bit of a nuisance at first. But as time goes on, Naruto could use his Saiyan powers to protect Bulma from various threats in the DBZ world. And Bulma would help Naruto understand the technology and culture of the DBZ universe, which is very different from his own.
Bulma, on the other hand, is the brilliant scientist from Earth. She's smart, sassy and not afraid to speak her mind. Their different personalities make for an interesting dynamic in the fanfiction.
