In fanfiction, it really depends on how the writer wants to portray it. If we consider raw power levels like in Dragon Ball Z, the Saiyans and other powerful characters have the ability to destroy planets. However, Naruto has his own set of powerful jutsu and the ability to harness the power of the nine - tailed fox. So, it could go either way based on the plot and the creativity of the fanfiction writer.
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.
Dragon Ball Battle was a strategy battle game based on the classic anime Dragon Ball. There were nearly 100 real Dragon Ball Warriors in the game, and players could experience the hot-blooded Dragon Ball battle scenes. The game introduced a 6v6 dynamic aerial combat mode, allowing players to carry out various types of combat such as assisting attacks, small skills, and killing. In addition, the game also provided a variety of playstyles, including the World's Best Martial Arts Competition, Dragon Ball Collection, World Boss, Snake Road, Extreme Challenge, etc., to meet the needs of PVP and PVE players. Players could improve their combat experience through training systems such as warriors and equipment. Dragon Ball Fight can be downloaded from the official website and app store.
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.
