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.
It's hard to say. Adult Goku has more experience and has achieved higher power levels. But Kid Goku has an unbridled potential that could make him a formidable opponent even to his adult self.
In the fanfiction, perhaps Kid Goku is on a journey to find stronger opponents to train with. He comes across Gine who is in a difficult situation, like being chased by some bad guys. Goku jumps in to save her. After that, Gine is so grateful that she decides to cook for Goku. As they sit down to eat, they start to exchange their life experiences. Goku is amazed by Gine's gentle nature, and Gine is impressed by Goku's courage and strength.
The two main characters are Kid Goku, the young and energetic Saiyan, and Gine, who is an important figure in the Saiyan world. Kid Goku is known for his love of fighting and his pure heart. Gine, on the other hand, has her own story and personality. In this fanfiction, their encounter will surely bring out different aspects of their characters as they interact with each other.
Another possible main character could be the villain that forces the two Gokus to meet. This villain could be a new, super - powerful threat that the two Gokus need to deal with. Their meeting becomes a crucial part of the story to defeat this powerful foe.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
There could also be other characters from the Dragon Ball universe making an appearance. For example, Vegeta might show up. He could be curious about Fem Goku and how she compares to Goku in terms of power. Or Bulma could be there, perhaps she's interested in the technology or biology behind Fem Goku's existence.
Perhaps they would team up against a common enemy. In fanfiction, new threats are often created. They could combine their strength and unique techniques to defeat the bad guy.
In some 'Goku meets Goku fanfiction', they could team up against a super powerful enemy that neither could defeat alone. They would combine their signature moves like the Kamehameha for an ultimate attack.
Often, Kid Goku is portrayed as the carefree and adventurous type. He's always looking for the next exciting thing to do, whether it's chasing after a strange animal or exploring a new area. He might be a bit naive in some aspects, especially when it comes to things like emotions.
