Maybe a new Saiyan who was born on a different planet and has a different understanding of Saiyan culture. He or she could come to Earth and interact with the existing Dragon Ball characters, bringing new fighting styles and a fresh perspective to the story.
Typically, the main characters would include Goku. He's the central figure in most Dragon Ball Z related stories. Vegeta would also likely be a main character as he is one of the most important Saiyans. And of course, there would probably be Piccolo, who has been a key ally throughout the series. These characters are often at the forefront of the action, whether it's fighting powerful villains or seeking new levels of power.
Pan is often a popular character. She's Gohan's daughter and has a lot of potential for interesting storylines in fanfiction. Goten is also quite popular, as he's a Saiyan with a lot of untapped power. Then there's Uub, who has the potential to be a very powerful character in the new generation. Also, any new Saiyan - human hybrids that people create in their fanfictions can be really popular as they can have unique abilities.
Well, obviously Gine is one of the main characters. She's the focus of the fanfic after all. There might also be other Saiyans like Bardock, as he was related to Gine. And perhaps some of the Saiyan warriors that she interacted with on a regular basis.
Probably Goku would still be one of the main characters. He's the face of Dragon Ball after all. Vegeta is also likely to be a main character as he's always been an important part of the story. Maybe there are new characters created specifically for the fanfic that also become main characters, but without reading it, it's hard to say for sure.
Goku could be the main character. Imagine Goku being hypnotized and having to fight against the control while still trying to protect his friends and the Earth. It would be a great twist on his usual heroic self.
Clearly, Cabba and Caulifla are the main characters. Cabba with his unique Saiyan heritage from Universe 6 and his own set of skills and values. Caulifla, on the other hand, brings her own brand of Saiyan fierceness and determination. Their different personalities and abilities are likely to be the driving force behind the events in the 'dragon ball cabba and cauliflower fanfic', whether it's them facing off against enemies, exploring new powers, or just having conversations that shape their relationship.
There could also be other well - known Dragon Ball characters like Goku and Vegeta. They might play important roles in guiding Cus, or they could be involved in battles and adventures alongside her.
Well, for a Dragon Ball harem fanfiction, Goku is a top candidate for the main character. He's the hero of the series, and his naivete about relationships combined with his strength would be really interesting in a harem setting. Bulma could also be a main character in a different way. She's smart and sassy, and if the fanfiction focuses on a female - centered harem, she could have a group of male Dragon Ball characters attracted to her. Additionally, Goten could be a main character. He's young and has a lot of potential for growth in a story where he has a harem of his own, with female characters seeing his potential as a future powerful Saiyan.
Trunks could also be a main character. He's from the future and has a cool attitude. In the fanfiction, he could be the new kid at school, trying to fit in while also having to deal with threats from his own time that somehow follow him to the school.
It could be a completely new character created just for the fanfic. Somebody with a booming voice and a flamboyant personality, who loves the thrill of the Dragon Ball Z battles.
