One great piccolo and oc fanfiction could be about an OC who is a trainee under Piccolo. The OC learns martial arts and self - discovery from Piccolo. Another could be a story where the OC has a special power that Piccolo is interested in and they form an alliance to protect the earth. And there could also be a fanfiction where the OC is from another dimension and Piccolo has to help the OC get back home while they face various challenges together.
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.
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.
There are fanfictions where the OC has a special power that Piccolo is intrigued by. In these stories, their relationship might start with Piccolo being suspicious of the OC but as they train together, a bond forms. For example, the OC might have a power related to nature that complements Piccolo's connection to the earth.
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.
Archive of Our Own (AO3) is also a great place to look. It has a well - organized tagging system.

Plus, AO3 has a community that often reviews and recommends good stories.
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.
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.
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.
