What could be the plot of a Dragon Ball fanfiction with a Weak Goku?

In a fanfiction, Goku might be weakened due to a curse. He loses his Super Saiyan powers and has to start from scratch. This could lead to a great character - development arc. He might discover new ways to fight without relying on brute strength, like using his wits and strategic thinking more, and also learning new martial arts techniques from his human friends.

One possible plot twist could be that Kid Goku is actually from an alternate timeline and has some powers that Dragon Ball Z Goku doesn't expect. Another could be that a villain uses their meeting to his advantage, like creating a rift between them to cause chaos.

Perhaps a fanfiction where Vados senses a new threat approaching the universe. She enlists Goku to help her find a way to stop it. Along the way, they encounter strange new races and powers. Goku's simple but powerful approach to fighting combined with Vados' wisdom would make for an interesting dynamic as they search for a solution to this impending doom.

One idea could be a time - travel fanfic where Bulma accidentally sends Goku back in time to a period before they met. Goku has to figure out how to get back while also dealing with the differences in that time period. Another could be a story where Bulma creates a new device that gives Goku a new power - up, and they have to test it out against a new, powerful enemy. A third idea is a fanfic set in an alternate universe where Goku and Bulma are the rulers of Earth and have to deal with diplomatic issues with other planets.

One possible plot could be that Android 21, with her unique powers, teams up with Goku to face a new and powerful enemy. They might have to combine their strength and fighting techniques to defeat this foe.

A plot could involve Goku being transported to a future where all his friends are dead and the world is in ruins. The unknown circumstances that led to this and the feeling of helplessness could make him scared. He then has to figure out how to go back in time and prevent this future from happening, all while being afraid of what he might find out about how this came to be.

Goku's understanding of different universes and races could be deepened in fanfiction. Since Dragon Ball Super introduced the multiverse concept, fanfiction could explore how Goku interacts with and learns from beings from other universes, making him more worldly and less naive in some ways.

One great 'Dragon Ball Goku Black Fanfiction' is 'The Dark Ascension of Goku Black'. It delves deep into Goku Black's psyche and his motives for his actions in a really interesting way. The author does a wonderful job of exploring his character beyond what we saw in the original series.

Caulifla and Goku's relationship in fanfiction could be really interesting. Maybe in this fanfiction, they start as rivals. Caulifla, with her Saiyan pride, wants to prove she's stronger than Goku. But as they fight more, they begin to understand each other's fighting styles and develop a mutual respect. This could lead to some really cool training sessions where they both learn new techniques from one another.

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.
