A fanfiction might explore the idea of Bardock seeing Goku's life through a time - space rift. He witnesses all of Goku's battles and the friends he makes. Bardock is filled with pride but also realizes that Goku has a different path than the traditional Saiyan way. This makes him question the Saiyan culture he once knew. Meanwhile, Goku starts to have strange dreams about his father, which leads him to search for more about his Saiyan heritage.
Redemption is another theme. Given her villainous origin in the original series, a lot of fanfiction writers like to explore the idea of Female Buu trying to make up for her past wrongdoings. This can involve her helping the Z - fighters in their battles or trying to become a more positive force in the Dragon Ball Z world.
In some fanfictions, Goku's death might be a sacrifice to save the universe. He could be facing an enemy so powerful that the only way to stop it is by giving up his own life. This would be a very emotional moment for his friends and family, like Chi - Chi and Gohan.
Well, 'Female Buu in the Human World' is quite popular too. This one focuses on Female Buu's experiences when she gets stranded in the human world. She has to learn about human emotions and ways of life, which leads to some really funny and heartwarming moments in the story.
The main characters often include Dark Goku and the Z - fighters. Among the Z - fighters, Piccolo is an important one. His wisdom and combat abilities can be crucial in dealing with Dark Goku. Krillin also has his place. His long - standing friendship with Goku and his own fighting skills add depth to the story. And Master Roshi might also make an appearance, perhaps as an advisor or someone who has some knowledge about an ancient power that could be relevant to the fight against Dark Goku.
One common theme is empowerment. Since Goku is already a very powerful character, in these fanfics where she's female, it often emphasizes her strength even more, showing that gender doesn't limit her abilities.
One interesting plot could be Dark Goku's origin story. Maybe he's not just an evil version of Goku but has a more complex backstory involving some dark magic or a different dimension's influence. Another plot might involve his battles against the Z - fighters. How he uses his unique powers against them and the strategies they come up with to counter him.
At first, Caulifla might be a bit intimidated by Goku's power. But as they train together, she would start to understand his techniques and philosophy of fighting. Goku would also learn from Caulifla's unique approach to battles. Their relationship could evolve into a deep bond where they rely on each other in tough battles. For example, Goku could save Caulifla from a near - death situation, and in return, Caulifla could come up with a creative battle strategy that helps Goku against a difficult opponent.
