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.
Well, if Thanatos invades the Dragon Ball universe, it could be a total chaos. The Dragon Ball characters are extremely powerful with their ki blasts and transformations. But Thanatos has his own set of abilities too. Maybe he would target the Dragon Balls themselves to gain ultimate power. The Z - fighters would surely put up a great fight though. They wouldn't just let an outsider take over their universe without a tough battle.
Well, a Hibari Kyoya Dragon Ball fanfic could explore how he adapts to the power levels in the Dragon Ball world. Since Dragon Ball has such high - powered battles and energy blasts, Hibari would have to find a way to either match that power or use his wits in a different way. For example, his strategic mind from his own series could help him outwit some of the villains in Dragon Ball, even if he doesn't have the same level of ki power.
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.
One interesting storyline could be about a new and powerful character emerging in Universe 9. This character might have a unique ability that challenges the existing power hierarchy. For example, they could control a type of energy not seen before in the Dragon Ball universe.
However, Goku is also a strong contender. His Super Saiyan forms give him incredible power boosts. If Naruto were in the Dragon Ball universe, Goku's experience with different power - ups and his intense training regime would make him a very difficult opponent to beat. But Naruto's unpredictable ninja skills might give Goku a run for his money.
Well, it could potentially be introduced as a powerful artifact. Maybe some kind of crossover event where the Dragon Balls' power attracts the attention of Marvel characters. They might see it as a source of unlimited power, like the Infinity Stones in the Marvel universe.
One possible fanfic could be about a new character in the Dragon Ball world who has a job delivering milk on foot. This character might encounter various Dragon Ball characters during their deliveries. For example, they could run into Goku while he's out training and Goku might be really interested in the milk as it could be a new and strange thing to him. The story could then revolve around how this milk delivery person gets involved in some of the adventures in the Dragon Ball world because of these chance encounters.
One way could be through a quirk accident. Maybe a character in My Hero Academia has a quirk that can open portals to different universes and accidentally opens one to the Dragon Ball universe. Then, the story can unfold as the characters from both universes interact, learn from each other's powers, and face new threats together.
Hulk's powers would likely be affected by the ki energy in the Dragon Ball Z universe. His gamma - based strength might be enhanced by ki, making him even stronger. Also, his ability to heal and regenerate could potentially be influenced by senzu beans or the natural healing properties of ki.
