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.
I'm not entirely sure which specific 'piccolo x gohan lemon fanfic' you're referring to. But generally, if it's a fan - made story, it might explore unique relationships and character developments. It could potentially show how Piccolo and Gohan interact in a different way than in the original series, perhaps delving into their friendship or a more complex emotional bond.
Another possible ending is that Gohan sacrifices himself to defeat Cell. He could use a self - destructive move that not only takes out Cell but also costs Gohan his life. This would be a very dramatic and tragic ending, but it would also show Gohan's selfless heroism.
One acceptable theme is their relationship in terms of power balance. How Piccolo's different forms compare to Cell's various stages of evolution. Also, the psychological aspect of their encounters, like how they perceive each other as opponents, can be a great theme for fanfiction.
Writing such fanfiction that involves inappropriate and non - canon sexual content is not appropriate. Dragon Ball series is mainly focused on action, adventure, and the development of characters and their powers, not this kind of vulgar content.
One great fanfiction could be about Gohan and Piccolo's training sessions. Gohan, with his Saiyan - human hybrid power, and Piccolo, the Namekian, could be exploring new ways to increase Gohan's power. Maybe they discover a new technique while sparring in the wilderness. This would not only strengthen their bond as mentor - student but also as friends who rely on each other in battles against stronger foes.
Training is also a popular theme. Since Piccolo was Gohan's mentor for a while, fanfics often show them training together and Gohan achieving new levels of power with Piccolo's guidance. There are also themes about family, as Piccolo becomes like an honorary family member to Gohan. He protects Gohan and is there for him in a way that is similar to a family member, and this aspect is often explored in fanfics.
One possible theme could be growth. Gohan has always been on a journey of growing up and Piccolo has been part of that journey. In the fanfiction, this growth could be explored in a more personal and emotional way, perhaps related to their relationship.
Trunks could also be a popular character in such fanfictions. He might be curious about Gohan's interactions with Cell and get involved in their affairs. His time - traveling knowledge could add an interesting twist to the story. Also, Vegeta could be included. His pride might not allow him to accept Gohan getting too close to Cell and he could try to put an end to their relationship or partnership in the fanfiction.
One possible theme could be friendship. Given that Piccolo and Gohan have a long - standing relationship in the Dragon Ball series, the fanfic could further explore the depths of their friendship, how they support each other through different challenges.
