A great OC Dragon Ball Z fanfiction might be one that reimagines the entire story from an OC's perspective. Say, an OC who was there from the very beginning, even before Goku met Bulma. This OC could have a different understanding of the Dragon Balls and their power, and the fanfiction could show how this different view affects the events as they unfold, leading to a very different Dragon Ball Z universe compared to the original.
There are many OC Dragon Ball Z fanfictions that focus on relationships. For instance, an OC might be a love interest for Goku or one of the other main characters. This could add a whole new layer of drama and character development. Some fanfictions also create OCs that are part of a new race in the Dragon Ball Z universe, like a race with the ability to manipulate time, and the story follows how the Z - fighters interact with this new race through the OC.
There are fanfictions where the female OC is a time - traveler. She could be from the future, coming back to change certain events in the Dragon Ball Z timeline. These stories often involve her interacting with Goku and his friends in interesting ways. Maybe she tries to prevent a certain villain from rising to power or has knowledge of future threats that the Z - fighters don't. This adds an exciting new dimension to the existing story.
There are fanfictions that focus on Yamcha's backstory. For example, a fanfic might explore his life before he met Goku and the others. It could detail his early days as a desert bandit and how he gradually became interested in martial arts. This can give a deeper understanding of his character.
One interesting 'Dragon Ball Z Zarbon' fanfiction could be about Zarbon's backstory before he joined Frieza's army. It might explore his home planet, his family, and what led him to become such a loyal follower of Frieza.
One interesting Dragon Ball Z Bra fanfiction could be about her training journey. Maybe she decides to train under Whis to become a powerful fighter like Goku. In this fanfic, she could face various challenges and learn new techniques.
One interesting 'Dragon Ball Z Bardock' fanfiction could be about Bardock surviving and coming back to change the course of Saiyan history. It might explore his relationships with other Saiyans in a new light, like how he'd interact with Goku differently.
A great 'Dragon Ball Z Towa' fanfiction could be one that imagines a scenario where Towa tries to recruit Goku to her side. This would create a lot of internal conflict for Goku as he has to decide between his love for fighting and his sense of right and wrong. There could also be fanfictions that explore Towa's powers in more detail. Maybe she discovers a new power within herself and has to figure out how to control it, all while the Z - fighters are trying to stop her from using it for evil purposes.
One interesting Veritas Dragon Ball Z fanfiction could be those that explore alternate universes. For example, a fanfiction where Goku never hit his head as a baby and how that would change the entire Dragon Ball Z storyline. Another could be about a fusion of different characters in a unique way that wasn't shown in the original series.
There are fanfictions that center around Trunks' training and his growth as a Saiyan. They might show his struggles to master new techniques and reach new levels of power, all while dealing with the threats that constantly loom over the Dragon Ball Z universe. These can be really exciting as they often add new twists to his character development.
There might be a fanfiction that focuses on Fasha's relationships. For example, it could explore her friendship with Bardock in more depth, showing how they supported each other during their Saiyan days. This could include flashbacks of their training together and the challenges they faced as young Saiyans.
One interesting crossover could be a battle between Hulk's brute strength and Goku's Super Saiyan power. Maybe in the fanfic, they start off as rivals, with Hulk misunderstanding Goku as a threat to Earth. Their fight would be epic, with Hulk's limitless rage against Goku's increasing power levels. It could also explore how their different universes' power systems interact.
