Well, in this fanfic, things might change in terms of character development. Maybe Piccolo becomes more powerful or Konna undergoes a significant transformation. Also, the story's setting or the relationships between characters could undergo alterations.
One interesting concept could be a power - level crossover. For example, how would Naruto's chakra - based powers stack up against the Saiyan power levels in DBZ. Maybe Naruto's ability to create multiple clones could be a strategic advantage against the brute force of DBZ characters.
Well, if we consider the power - scaling in their respective universes, Goku has fought opponents on a galactic level. However, Naruto has also faced extremely powerful foes within his own world. If Naruto could somehow use his Sage Mode and Kurama's chakra in a really efficient way, he might stand a chance against Goku. But Goku's experience in combat across different planets and his instant transmission ability would also be major factors in a fight.
One idea could be exploring the Supreme Kai of Time's untold backstories. Maybe she had some secret training or a special encounter in the past that shaped her into the being she is in the DBZ universe.
I haven't actually read this specific 'piccolo and gohan lemon fanfiction', but generally, in fanfictions involving these two characters, it might explore their relationship in unique ways. It could be about their friendship evolving, or perhaps their teamwork in new and unimagined scenarios within the Dragon Ball universe.
A major theme is identity. Since she is a female version of Piccolo, she has to come to terms with who she is compared to the original Piccolo. Family also plays a role. In some fanfictions, she might be searching for her family or creating a new family of her own. Additionally, the theme of good vs. evil is common, as she battles against various villains.
I'm not that familiar with the specific 'Brian Piccolo Thanksgiving Day story'. Maybe it could be about how he spent the Thanksgiving Day with his family, sharing a big meal and giving thanks. It might also involve some special traditions he had on that day.
