First, think about the personality of your OC. Is it brave, timid, curious? Then, consider how your OC will interact with Piccolo. Will they be friends, or will there be some initial conflict? Next, create a plot. It could be about saving the world, or just a simple adventure. For example, your OC could discover a new power and Piccolo helps them master it.
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.
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.
The relationship could start off very rocky. King Piccolo is used to being in control and his son might be more independent - minded. But over time, they could develop a grudging respect for each other. For instance, if the son shows great strength in combat, King Piccolo might start to see him as an equal.
One way is to have a magical accident. Maybe a wizard in the Harry Potter universe was experimenting with interdimensional travel and accidentally brought Vegeta and Piccolo to the stadium in the wizarding world. Then they all have to figure out how to get back to their own worlds while dealing with the chaos that ensues in the stadium, like angry fans or other magical creatures that are attracted to the strange energy.
Writers develop their characters by showing their growth. For example, Piccolo might become more in touch with his emotions. And Chichi could become more accepting of different beings.
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.
