There could be a fanfiction where Goku Black travels back in time to a period before he became a villain. He then has the chance to change his future and avoid the path that led him to become the antagonist. This would involve him interacting with his past self and trying to convince himself to take a different route. It could also show his internal struggle as he is torn between his original ideals and the dark path he eventually took. This type of plot would focus on his character growth and redemption, rather than any inappropriate content.
One interesting plot idea could be exploring Goku Black's perspective on the multiverse. How does he view different versions of himself and the other characters? Another idea could be a story where Goku Black has to team up with his enemies, like Goku and Vegeta, to face a greater threat that endangers all of the universes. This would force him to put aside his differences and work with them, leading to some interesting character dynamics.
A plot idea could be Goku Black getting stranded in a timeline where he has no allies and has to survive on his own. He would have to learn to adapt to the new environment and its rules, and maybe even make some unexpected friends along the way. Or perhaps a story where Goku Black discovers a new form of power that is not related to the Saiyan transformations, and he has to figure out how to control it while also keeping it a secret from his enemies and former allies.
