In this fanfiction, it could be that Goku is transported to a different dimension where he meets a powerful warrior who is also kind - hearted. They team up to fight a common enemy at first. During their time together, they start to have a connection. Goku, who has always been focused on fighting and protecting, now has to figure out how to balance this new relationship with his duties on Earth.
Maybe Goku accidentally saves a female alien during one of his adventures. She is from a race with unique powers. She becomes intrigued by Goku's strength and simplicity. As she stays around to learn more about Earth and Goku, they start to fall in love. Their relationship could be tested by the fact that she has responsibilities in her own world.
It could be a female Namekian. Since Namekians are also very strong and have their own unique culture, a female Namekian could catch Goku's eye. They might bond over their mutual respect for life and their experiences with fighting powerful foes.
Well, it could be really interesting. Maybe Goku would find someone who challenges him in a different way than Chi Chi did. This new love could be a powerful fighter from another planet, and they bond over their shared love for battle and protecting the universe. It would be a big change for Goku, as his relationship with Chi Chi was more about family and domestic life in some ways.
One plot could involve time travel. Android 1 travels back in time and meets a younger Goku. At first, Goku is suspicious of her, but as they interact more, they start to care for each other. Android 1 tries to help Goku in his battles against the Saiyans in this timeline. Their love story unfolds as they try to change the future for the better, with their relationship being a key factor in uniting different factions in the fight against greater threats.
A possible plot could be that a powerful magical artifact causes Goku and Tsunade to swap bodies for a while. During this time, they have to learn about each other's lives and powers. As they do this, they gain a newfound respect and admiration for one another. Eventually, when they return to their original bodies, their relationship has changed, and they start to fall in love. Or maybe there is a prophecy that only the combined power of Goku and Tsunade can defeat a great evil. As they work towards fulfilling the prophecy, they grow closer and fall in love. There could also be a plot where Goku is invited to the Naruto world for a martial arts tournament, and he and Tsunade meet there. Their relationship then develops as they interact during the tournament and the events that follow.
In such a fanfiction, Goku might be kidnapped by a powerful new villain. His friends would then start a search mission. Maybe Vegeta would be the first to volunteer, thinking it's his chance to prove he's stronger than Goku.
Maybe Kale is sent on a mission to Earth and Goku is the one who helps her adapt. They start training together and during the training sessions, they discover they have a lot in common. Their shared love for fighting and getting stronger becomes the foundation of their romantic relationship.
Well, it could be about Goku Jr learning some of Goku's most powerful moves. Maybe Goku teaches him the Kamehameha. They might also go on an adventure together, like fighting a new and powerful enemy that neither could face alone.
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.
Perhaps the story focuses on how Jaime gets the new hand. It might be a gift from a mysterious figure. Or it could be the result of some high - tech experiment. Then, Jaime has to learn to adapt to this new addition to his body, dealing with things like how people around him react and how to use the hand effectively in his daily life.
