What could be an interesting plot for a Goku and Naruto crossover fanfiction?

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.

One possible plot could be that Goku somehow gets transported to the Bleach universe. He might initially be confused by the concept of Hollows and Soul Reapers. But then, with his power, he could start fighting Hollows, thinking they are some sort of new villains. His ki-based attacks would be a new and powerful force in the Bleach world, and he could end up teaming up with Ichigo to fight a common, extremely powerful enemy, like a super - powerful Hollow that even the Soul Reapers are having trouble with.

One possible plot could be Goku from the SSJ4 form crossing over into the world of Dragon Ball GT. He could encounter new threats that require his ultimate form to defeat. Maybe he teams up with the other Z - fighters in that universe to face off against a powerful and ancient evil that was sealed away long ago and has now been unleashed.

One possible plot could be that Lemon, with her unique abilities, somehow gets transported to the Dragon Ball universe. Goku, being the curious and friendly Saiyan he is, decides to help her find her way back. Along the way, they face some common enemies. Goku teaches Lemon about ki and fighting techniques, and Lemon shows Goku some of her own skills from her world. This could lead to an epic team - up against a powerful villain who threatens both their worlds.

One possible plot could be that Goku accidentally travels to a world where Lemon is a powerful being. They start as rivals but gradually learn from each other's strengths. Goku could teach Lemon about his fighting techniques and his Saiyan heritage, while Lemon could show Goku some unique powers or skills from their world. Then they team up to face a common enemy that threatens both of their worlds.

One idea could be a tournament where Goku and Naruto are both invited. They start off as rivals but then realize they have more in common as they face powerful opponents together. Another could be a situation where an enemy from Goku's universe somehow ends up in Naruto's world and they have to team up to defeat it. A third idea is that a magic spell or some kind of power - related accident causes their powers to be swapped, leading to comical and also challenging situations as they try to adapt to each other's abilities.

One possible interesting plot could be Goku, in his godlike form, being transported to different universes where he meets various female characters from different shows or stories. He then has to form alliances with them to fight a common evil. As they spend time together, romantic feelings start to develop among them, creating a harem dynamic.

One possible plot could be Goku, in his Saiyan tenacity, challenges the God of Destruction to a friendly spar. The God of Destruction initially scoffs but is soon impressed by Goku's power. As they fight, their powers start to blend, creating new energy forms that threaten to disrupt the balance of their universes. They then have to team up to contain this new energy while also learning from each other's fighting styles.

One possible plot could be that Goku somehow gets transported to the Fairy Tail world. He could join forces with Natsu and the gang to fight against a common enemy like Acnologia. Goku's power levels would be off the charts compared to most in Fairy Tail, but he'd be intrigued by their magic. Maybe he'd learn some magic himself or teach them some of his ki techniques.

A plot could involve Goku being summoned to the DC Universe by a powerful magic user who believes Goku can help stop an impending apocalypse. The Justice League is skeptical of this strange, powerful being from another world. However, as they face challenges together, they start to trust Goku. For example, when they are up against a horde of powerful demons, Goku's speed and strength are crucial. He could teach some of the League members about ki control, and in turn, they could teach him about teamwork in a more strategic sense compared to his usual battles on Earth.
