A more action - packed storyline could be Chichi getting kidnapped by an old enemy of Goku. Goku then has to race against time to save her. Along the way, he might face some new and powerful foes. Goku's determination to save his beloved Chichi would be the driving force of this exciting story.

Maybe a fanfiction where Caulifla develops feelings for Goku during their training sessions. However, Goku, being oblivious as he often is, doesn't notice at first.

Their relationship could be a mix of friendship and the start of something more, with a lot of action-packed scenes in between.

Another possible storyline is that Android 21, who is usually seen as a bit of an outcast, finds acceptance in Goku's group. Goku encourages the others to give her a chance. They then go on adventures together, with Android 21 constantly evolving not just in power but also in her understanding of the world around her.

One popular storyline could be Goku using his smarts to outwit a new and powerful enemy that can't be defeated by brute strength alone. For example, he might figure out the enemy's weakness through careful observation and analysis, much like a detective. Another could be Goku using his intelligence to solve a problem in the Dragon Ball universe that affects all the characters, like a mysterious energy drain. There are also fanfictions where Goku's smart side helps him train his friends more effectively, leading to new power - ups for everyone.

In a fanfic, it could be that Android 21 has a hidden power that only Goku can unlock. As Goku helps her discover this power, they form a deep bond.

One interesting storyline could be about them exploring a new planet together. Bulma uses her inventions to get them there, and Goku has to face new and strange enemies. Another could be a time - travel fanfic where they go back in time to change certain events in the Dragon Ball universe.

Another storyline could be a time - travel one. Android 21 somehow gets sent back in time and meets a younger Goku.

They could team up to prevent some of the future disasters that Android 21 knows about.
