In the fanfiction, their relationship could be one of mutual admiration. Kid Goku would look up to Future Goku for his experience and power. Future Goku, on the other hand, would be charmed by Kid Goku's innocence and raw potential. They could train together, and during this process, they would form a strong brother - like relationship.
They would likely have a very strong bond. Since they are brothers, they would support each other in battles and in their personal growth.
Through shared battles. When they fight side by side against common enemies, they start to trust each other more. For example, in a fight against a group of powerful androids created by a mad scientist, they rely on each other's strengths. Goku uses his martial arts skills and Android 21 uses her technical abilities to analyze the opponents' weaknesses.
By showing Gine as a protective figure in Baby Goku's life. For example, she could save him from a minor danger, like a small wild animal attack. This would make Baby Goku look up to her more and strengthen their relationship.
The relationship could start with hostility. Towa might see Goku as a threat to her plans and Goku sees her as an evil force. But then, when they are forced into a situation where they need to rely on each other, like being stranded in a strange realm. They begin to see each other's strengths. For example, Goku might admire Towa's intelligence in dealing with the strange environment, and Towa might be impressed by Goku's unwavering determination.
At first, it might be tense. Bardock is a hardened Saiyan warrior from a different era, and Goku has grown up on Earth with a very different set of values. But as they start to communicate, they would find common ground in their Saiyan blood. Goku's pure - heartedness could gradually win over Bardock, and Bardock's strength and pride could earn Goku's respect.
Perhaps the goddess has the ability to see different timelines. She sees a future where Goku is the most important figure in the universe's survival. So she travels back in time to meet him when he's still young. She becomes his mentor, guiding him not just in power but also in understanding the greater cosmos. As Goku grows up, he starts to see her not just as a mentor but as a love interest, and they develop a relationship that spans different stages of Goku's life.
In a fanfiction where Kid Goku meets Future Goku, one possibility is that Future Goku would be amazed at seeing his younger self. He might share some of the dark experiences he has had in the future, like the battles against powerful enemies and the losses. Kid Goku, being young and full of energy, could be inspired by Future Goku's strength and determination. Maybe he would start training even harder, eager to reach the level of his future self.
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.
At first, it could be a bit rocky. Bardock is used to the harsh Saiyan ways, while Goku has been raised on Earth with different values. But as they spend time together, they start to understand and respect each other. Bardock could become a mentor to Goku, teaching him advanced Saiyan fighting techniques and Goku could teach Bardock about friendship and love.
Well, in many fanfictions, their relationship often develops through shared experiences. For example, they might go through tough times together, like dealing with threats to their family or the Earth. These experiences bring them closer and make their kisses more meaningful, as they represent a deeper bond formed through adversity.
