Uub is often characterized as a pure - hearted character in Dragon Ball Super fanfic. His origin as the reincarnation of Majin Buu gives him an interesting backstory. He's usually shown as having a strong sense of justice, much like the other heroes in the Dragon Ball series.
There are no such inappropriate 'Straight Shota' stories in the official Dragon Ball Z canon. Dragon Ball Z mainly focuses on epic battles, power-ups, and the adventures of Goku and his friends to protect the Earth from various villains.
Well, in a lot of Dragon Ball Super fanfic, Uub is seen as a bit of an enigma. Since he's a reincarnation, there's always the question of how much of Buu's power he can truly access. Some fanfics focus on Uub's relationships within the Dragon Ball universe. For example, his interactions with the younger generation like Pan could be really interesting. He could also be a key figure in new storylines that involve threats from other universes, as his power might be the tipping point in battles.
The Dragon Ball Z Henti manga is an unauthorized and inappropriate version that differs significantly from the original in content and nature. The original is a well-known and legitimate manga with a focus on adventure and action.
One alternative is to focus on character backstories. You could write about the early days of Piccolo, how he came to be the way he is. Another option is to do crossovers with other non - sexual universes. Maybe a story where the Dragon Ball Z characters meet characters from a magical anime world and they have to work together to solve a problem. Also, you can write about the relationships between the characters in a platonic way, like the deepening of the friendship between Gohan and Krillin.
A Kryptonian in the Dragon Ball Z universe could potentially be a very powerful addition. Their natural abilities like super strength, flight, and heat vision could make them a force to be reckoned with. However, they would also face challenges as the Dragon Ball Z world has its own power scale with ki-based powers. They might have to adapt to the different fighting styles and power sources. Maybe they could learn to use ki in addition to their Kryptonian powers, or they could find a way to combine the two in unique ways.
Dragon Ball Z is both anime and manga. The anime was adapted from the manga and they share the same story and characters, but presented in different mediums.
