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.
Goku Black in Dragon Ball Legends has a really interesting story. He is an evil version of Goku from an alternate timeline. He shows up with his menacing aura and powerful abilities, causing chaos in the Dragon Ball Legends' universe. He often engages in intense battles against the good guys, and his fighting style, which is similar to Goku's but with a dark twist, makes him a formidable foe.
Well, one creative idea is a fanfiction where Goku Black teams up with his alternate selves from different timelines. It would be really cool to see how their combined powers and different personalities interact. They could create a super - powerful force that no one in the Dragon Ball universe could expect.
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 of the main events is his sudden appearance in the game world. He starts attacking the heroes without warning. Another event is his battles against the main protagonists like Goku, Vegeta etc. These battles are intense and often change the power dynamics in the game.
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.
There are a considerable number of Dragon Ball manga. It's a long-running and popular series, but the exact count might vary depending on how you classify different editions and spin-offs.
