Imagine Goku meeting Lucy. Lucy, being a celestial spirit mage, would be fascinated by Goku's power. Goku, on the other hand, might not understand the concept of celestial spirits at first. But as they interact more, Goku could help Lucy become stronger physically, while Lucy could introduce Goku to the magical side of the Fairy Tail world. Goku could also have interactions with Gray. Gray's ice - make magic would be a contrast to Goku's heat - based ki attacks. They could have friendly battles to test each other's strength.
A Goku and Goku Black fusion in fanfiction could be really exciting. The fusion would inherit Goku's love for fighting and getting stronger, but also Goku Black's ambition. Their combined ki could be a new type of energy that no one has ever seen before. This new fused form might also have new transformations or abilities. For example, it could combine Goku's Super Saiyan forms with Goku Black's Rose form in unexpected ways. It could change the power balance in the Dragon Ball world and open up all sorts of new storylines, like teaming up with other characters to take on new threats or even having internal struggles between the two personalities within the fusion.
There could also be a moment of self - discovery for both of them. Goku might see his past self in Kid Goku and realize how far he has come, while Kid Goku could get a glimpse of his future potential through meeting his adult self. They could share stories about their friends and enemies, like how Goku could talk about Vegeta and Frieza to Kid Goku, and Kid Goku could tell Goku about his early battles with the Red Ribbon Army.

However, it could also cause chaos as their different personalities clash within the fused form.
