What could be the plot of a 'Goku Black Turns Good' fanfiction?

It could lead to a really interesting plot twist. Maybe he realizes the error of his ways and decides to use his power for good.

Obviously, Goku Black himself is the key character as the story revolves around his transformation. Goku would also be important as he could be the one who shows Goku Black the path of good, either directly or indirectly.

The plot could involve Goku and Goku Black fusing accidentally. Maybe due to some strange energy anomaly. And then they have to figure out how to control this new form. They might initially be feared by their friends because of Goku Black's reputation, but then they prove that they are on the side of good by using their new powers to protect the Earth from an impending threat that no one else could handle.

Well, perhaps in this fanfiction, Goku Black makes a fatal mistake. He could underestimate Goku's ability to adapt during battle. Goku, being the experienced fighter he is, notices this weakness and uses it against Goku Black. He might use a combination of his signature moves like the Kamehameha in a new and unexpected way that catches Goku Black off - guard, leading to his defeat.

Well, perhaps it could be about Izuku learning Goku Black's unique combat styles and techniques. Maybe Goku Black would push Izuku to his limits in training, helping him gain new powers and a more ruthless edge in battle.

A plot could involve Goku Black arriving in the Naruto world during a time of great unrest, like when the Akatsuki is causing chaos. He sees the shinobi as weaklings compared to his Saiyan strength. However, Naruto, with his Sage Mode and Nine - Tails chakra, manages to hold his ground against Goku Black in a first encounter. This catches Goku Black's attention, and he decides to study these 'new' powers. Meanwhile, the shinobi villages must decide whether to see Goku Black as a potential threat or an opportunity to learn from his power. Eventually, they could team up to fight a greater evil that emerges due to Goku Black's presence in their world.

It could be insanely powerful. Goku already has incredible power levels, and Goku Black is no slouch either. When they fuse, it's like combining two nuclear reactors. Their power could be so great that they could effortlessly destroy planets just by flexing their newfound power. They might be able to reach Super Saiyan forms that are far beyond what we've seen in the official series, with power levels that are basically off the scale.

Bulma could be a catalyst. She's very intelligent and might come up with some sort of device or plan that could change Goku Black's perspective. Maybe she creates a machine that can influence his mind just enough to make him start to question his evil ways.

The fanfic might focus on her relationship with the other Z - fighters. She could start off as an antagonist but then gradually learn the value of friendship and turn into an ally. For example, she might initially be on a mission to carry out her father's evil plans but then realizes the error of her ways through interactions with Goku and his friends.

One idea could be that Goku and Goku Black are forced to team up against an even greater threat from another universe. They start to understand each other's fighting styles during the battle and gradually develop a grudging respect for one another.
