A lesser - known but still good fanfiction is 'Goku and the Mysterious OC'. In this, the OC has a secret past and as Goku gets closer to her, he discovers more about her and himself. The author does a great job of building the relationship between them in a believable way.
One common theme is power - up. The OC usually has some sort of unique power or ability that they either learn to control better or gain more of with Goku's help. For example, in many fanfictions, the OC might start with a weak power but end up becoming really strong like Goku.

In 'oc son of goku fanfiction', antagonists can also be from other universes. There could be powerful warriors from parallel universes who come to challenge the OC because they see him as a key to controlling the multiverse or because they want to prove their universe's warriors are stronger. Also, some of Goku's old enemies might have descendants who hold grudges and target the OC as a way to settle old scores.
One common theme is power growth. Just like in the original Dragon Ball series, in these fanfictions, both Goku and the oc saiyan usually strive to become stronger. They might train together or learn from each other's techniques.
Sure. Fanfiction is a realm of creativity. Regarding Goku and Bulma in love, it can be a fascinating concept. In the original series, their relationship is more of a friendship - based one. But in fanfiction, a writer could start from their early interactions. Maybe Bulma was initially annoyed with Goku but then grew to appreciate his simplicity and strength in a new way. And Goku could come to realize that Bulma offers him a different kind of support compared to his other friends. This could lead to a slow - burning love story that could be both endearing and exciting for readers who are looking for a fresh take on the Dragon Ball characters.
Sure. There could be fanfiction on this. Goku is a well - known character for his strength and determination. Android 21, on the other hand, has her own allure. Writers might find it interesting to pair them up romantically. It could involve Goku helping Android 21 understand more about humanity and love, or perhaps Android 21 being drawn to Goku's unwavering spirit in a way that develops into love.
It could be a female Namekian. Since Namekians are also very strong and have their own unique culture, a female Namekian could catch Goku's eye. They might bond over their mutual respect for life and their experiences with fighting powerful foes.
Friendship is also a big theme. The OC and Goku usually form a bond. They rely on each other in battles and in their personal growth. For instance, they might learn from each other's mistakes and support each other when facing difficult opponents.
One popular trope is the 'Powerful OC' trope. In many Goku x OC fanfictions, the OC is often created with unique powers that either complement or rival Goku's. Another is the 'Training Partner' trope, where the OC becomes Goku's training partner and through their training sessions, a relationship develops. And the 'Saved by Goku' trope is also common, where the OC is in some sort of danger and Goku comes to the rescue, which then leads to their relationship evolving.
