There could be a group of rebels in this other world who are fighting against an oppressive regime. Vegeta, with his combat skills, could be a valuable asset to them. And they could help him in his quest to find a way back home.
It really depends on the context. If it's a physical strength battle, Vegeta might have the upper hand initially due to his Saiyan strength. But Naruto has incredible stamina and the ability to tap into the Nine - Tails' power. So in a long - drawn - out fight, Naruto could potentially outlast Vegeta.
It's a bit hard to say for sure. Both Vegeta and Goku have their moments of strength. Goku has some unique powers and techniques that give him an edge at times, but Vegeta is no slouch either and constantly works to catch up and surpass Goku.
Obviously, Goku would be a main character he'd interact with. If he goes back to when Goku was a kid, he could train with him, or try to convince Goku's grandpa to let him train Goku in a different way. Another character would be Bulma. If he goes back far enough, he could meet a younger Bulma and perhaps change their relationship dynamics. He might also interact with his younger self. This could lead to some really interesting self - reflection and growth as he tries to guide his younger, more hot - headed self.
It could be Frieza. Frieza has a long - standing grudge against the Saiyans, especially Vegeta. He might kidnap Vegeta to torture him or to use him as a bargaining chip against the other Saiyans. Another possibility is Cell. Cell might see value in Vegeta's genetic material and kidnap him to extract it for his own evolution.
Bulma could be involved. Since she has a relationship with Vegeta and is friends with Goku, she might try to mediate between them when Goku snaps at Vegeta. She could be the voice of reason, trying to calm both of them down and make them see each other's point of view.
Another character could be Dr. Briefs, Bulma's father. In the alternate universe, he might have a more prominent role in bringing Vegeta and Bulma together. For example, he could be the one who arranges for Vegeta to work on a project with Bulma, which starts their relationship on a more professional note that gradually turns into something more personal.
Well, obviously Female Vegeta herself is a very popular character. She is often portrayed as strong - willed and having all the Saiyan pride just like the original Vegeta. Goku also makes appearances in many of these fanfictions. His carefree and powerful nature contrasts with Female Vegeta's more serious and prideful demeanor. Another popular character is Bulma. She might interact with Female Vegeta in different ways, like providing her with some tech or just being a friend and giving her advice on Earthly things.
The main characters would obviously be Vegeta and Bulma. Vegeta is the Saiyan prince, a powerful and often brooding character. His presence brings a sense of strength and an otherworldly quality to the story. Bulma, on the other hand, is a human, a brilliant scientist. She's strong - willed and independent, which makes for an interesting dynamic when paired with Vegeta, especially during her pregnancy.
