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.
In some 'Vegeta goes back in time' fanfictions, Vegeta might go back to the time when the Saiyans were still under the rule of King Vegeta. He could try to change the Saiyan culture from being so war - like and brutal. He might introduce new ways of thinking and training that would not only make the Saiyans stronger but also more united. This could lead to a completely different future for the Saiyans, where they don't get wiped out by Frieza and instead become a more dominant force in the universe. He could also form different alliances with other races much earlier, which would change the power dynamics in the galaxy.
Well, he could change a lot of things. Maybe he'd prevent some of the big battles or save some characters who died in the original timeline. For example, he might stop Frieza from destroying Planet Vegeta earlier. It would also be interesting to see how his Ultra Instinct powers interact with the past events and characters who haven't seen such power before.
I'm not sure specifically as the title is rather unique. It could potentially be about a character named Ultra who is involved in a war and there are some secret aspects to this story. Maybe it's a fictional war story with hidden plots and mysteries.
There are several ways to make yourself less important in a first-person novel:
1. avoid describing your own identity and personality directly. Instead, tell the story from the perspective of others and let your character represent yourself. For example,"When I woke up, I found myself lying in a strange place. I don't know where I am or why I'm here."
2. Reduce the description of oneself. Avoiding the description of one's appearance, personality, emotions, etc. Instead, let the character tell the story according to their own feelings and thoughts. For example,"I feel so cold that my entire body is wrapped in a thick coat."
3. Use the character's behavior and dialogue to show that you are fading away. For example, the characters might behave differently from themselves, making it difficult for the readers to realize that the characters were actually the same person. For example,"He (Character A) doesn't seem to care that he's watching TV with a cigarette in his mouth."
4. Use the plot and plot to weaken yourself. For example, when the character faces difficulties or challenges, he may show a state of self-doubt or loss, which makes the reader realize that the character has not completely faded away. For example,"I don't know what I should do. I feel like I'm in a state of confusion."
These are some of the ways to play down the ego in a first-person novel. You can choose and use them according to the style and plot of the novel.
In the fanfiction, perhaps it focuses on the initial spark between them. It might show how Vegeta, with his tough exterior, starts to soften a bit when he's around Bulma. For example, he could start to notice small things about her, like the way she furrows her brow when she's thinking hard about something in her lab, and that starts to draw him to her.
Well, an ego trip in this story might be about the character's pursuit of things that boost their own ego. It could be achieving certain goals just for the sake of feeling superior or getting recognition. For example, if Dexter in the story is constantly trying to outdo others in his work not for the actual value of the work but just to satisfy his ego.
