A third idea is that the character reincarnates into a non - Saiyan race, like a Namekian. Since they have the memories of their past life, they try to change the fate of Namekians. They might use their knowledge of future threats to build stronger defenses for Namek and also try to find a way to make the Namekian Dragon Balls even more powerful.
One idea could be that the reincarnated character has knowledge of all the Dragon Ball series in their past life. So they start training in a unique way early on, like combining different fighting styles from different sagas. For example, they might mix Goku's Kaioken with Vegeta's Galick Gun at a very young age, which surprises everyone in the Dragon Ball world.
Another plot could be that the reincarnated person is reborn as a Saiyan, but with a strange power that doesn't exist in the normal Saiyan biology. Maybe they can control time on a small scale, like being able to slow down time for a few seconds during a fight. This new power would draw the attention of both the good and bad guys in the Dragon Ball universe.
A possible plot is that the reincarnated person has a special power from their previous life that doesn't exist in the Dragon Ball world yet. Maybe it's a unique form of magic. This new power attracts the attention of both the heroes and the villains. The Z - fighters might be curious and want to learn from it, while the villains see it as a means to gain an advantage over their enemies.
One idea could be a story where Goku and Vegeta from Dragon Ball Super end up in the world of Dragon Ball GT by some sort of time - space rift. They then have to team up with the GT versions of themselves to fight a new, powerful enemy that is threatening both timelines.
A great plot idea in 'reborn in dragon ball fanfiction' could be the reborn character having a special connection with the Dragon Balls themselves. Instead of just using them to make wishes, they could communicate with the dragons in a more profound way. This connection might give them powers related to the Dragon Balls, such as the ability to teleport to the location of the Dragon Balls or to call upon the dragons for help in non - traditional ways during battles.
A cool plot could involve a new villain who is able to control time in a different way than Cell or the Supreme Kai of Time. This villain uses time - based attacks and defenses, and the Z - fighters have to learn new techniques to combat it. In this fanfiction, the RPG elements could include leveling up their time - related skills. Also, a story about a character who is half - Namekian and half - human trying to find their place in the Dragon Ball universe could be really engaging.
