A third idea might be a fanfic where a Futanari character is from an unknown planet but has a connection to the Dragon Balls. They come to Earth in search of the Dragon Balls, not for wishes like most, but to study their power source. Along the way, they meet the Z - Fighters and have to prove themselves worthy of being part of the group.
Well, in hentai Dragon Ball fanfic, a common idea is transformation - related themes. When characters transform in Dragon Ball, it can be used as a catalyst for different relationships in fanfic. For instance, when Gohan transforms into a Super Saiyan 2, how does that change his relationship with Videl in a more adult - inspired story? Another idea is about the different races in Dragon Ball. The Namekians, Saiyans, and Humans could have cross - race relationships explored in fanfic. And of course, the eternal battle between good and evil can be twisted into relationships in the fanfic world.
A popular idea might be a fanfic that delves into Caulifla's relationships with other characters in her futanari form. It could explore how her new form affects her interactions, like with her friends or rivals. For example, how she might use her unique abilities in battles against foes who underestimate her due to her different form.
One popular idea could be Bayonetta's adventures in different realms. For example, she could explore a realm full of ice and have to battle ice - themed enemies. Another idea could be her teaming up with other characters from the game universe to take on a powerful new threat. Also, a fanfic could focus on her training a new apprentice and passing on her skills.
One interesting idea could be how the concept of hypnosis is integrated into the Dragon Ball universe. Maybe it's used as a new form of combat strategy, where a character hypnotizes their opponent to lower their guard or make them perform certain actions against their will.
One idea could be exploring Cus's training in a new dimension. Maybe she discovers a hidden power within herself during a sparring session with an unknown opponent.
A crossover with One Piece might also be cool. Imagine Luffy and Goku teaming up. Luffy's rubber abilities combined with Goku's super strength could make for some really fun and unique battle scenes. They could be on a quest to find a powerful treasure that has both the power of the One Piece world and the Dragon Balls.
One idea could be exploring an alternate universe where the Saiyans never destroyed Planet Vegeta. In this fanfic, Goku could grow up among his Saiyan brethren and learn different fighting techniques from them. It would be interesting to see how his character develops in a more Saiyan - centric environment.
One idea could be a story where two female Saiyan characters from different timelines meet and form an unexpected bond. They could train together and face challenges side by side, while also exploring their new - found friendship which might have some undertones of a deeper connection.
One idea could be a crossover where Ruby and her team encounter the Saiyans. Maybe they team up to fight a common enemy that threatens both Remnant and the Dragon Ball universe. For example, a powerful demon or an ancient evil that has the power to destroy multiple dimensions.
One idea could be exploring a new transformation for the characters. For example, a fusion between an unexpected pair of characters that results in a super powerful form. Another idea is to set the fanfic in an alternate universe where the Saiyans never lost their planet and see how that changes the story and power dynamics. You could also focus on a side character and give them a more in - depth backstory and a major role in saving the universe.
