The plot might involve the Kryptonian woman being in trouble. Maybe she's on the run from some villains who want to use her Kryptonian powers for evil. Goku stumbles upon her and decides to protect her. Along the way, they discover that their powers can be combined in unique ways. For example, Goku's Ki blasts combined with her heat vision could create a super - powerful attack. Their relationship develops from a protector - protectee one to a deep friendship, and they work together to stop the bad guys.
In this fanfic, the story could start with the Kryptonian woman arriving on Earth by accident. Goku, being the curious and friendly person he is, approaches her. They are both intrigued by each other's powers. They start training together, and the Kryptonian woman is amazed at how Goku can constantly increase his power level. As their bond grows, they find themselves in a situation where they have to save Earth from an alien invasion. Goku uses his martial arts skills and the Kryptonian woman uses her super strength, flight, and other abilities to fend off the invaders.
One possible plot could be that Goku, during one of his intergalactic travels, lands on a planet where he meets a Kryptonian woman. They initially start as sparring partners, testing each other's strength. As they spend more time together, they learn about each other's cultures. Goku teaches her about the Saiyan ways, like the importance of training and the concept of Super Saiyan forms. She, in turn, shows him some of Krypton's advanced technology that survived its destruction. Eventually, they team up to face a common enemy that threatens both their home planets in a way.
The language barrier could be a challenge. Goku speaks his own language, and although he can communicate with others on Earth, the Kryptonian woman might have a completely different language. They would need to find a way to communicate effectively, perhaps with the help of some sort of translation device or learning each other's languages. Another challenge could be the expectations of their respective communities. Goku has his friends and family on Earth who might be wary of this new relationship, and the Kryptonian woman might have her own set of people (if there are any other Kryptonians left) who have different views on inter - species relationships.
One possible plot could be that Goku and Wonder Woman meet during a multiverse crisis. They initially clash due to their different fighting styles and values. Goku is all about the thrill of battle and self - improvement, while Wonder Woman is more focused on justice and protecting the innocent. But as they face a common enemy that is threatening both their worlds, they learn to combine their powers. Goku's energy blasts and super - speed combined with Wonder Woman's strength and lasso could make for an epic battle against the foe.
One possible plot could be Bardock's adventures before Goku was born. Maybe it could show how he dealt with the Saiyan politics and his growing concerns about Frieza's rule. This could set the stage for Goku's future battles as his son.
A lot of these fanfics also deal with the idea of protecting the universe. Both Goku and a female Kryptonian are powerful beings capable of great things. So, they might team up to fight a common enemy that threatens the entire universe. This theme gives the writers a chance to create epic battles and show the combined strength of these two characters, while also exploring their relationship in the context of a high - stakes situation.
It could be a story of redemption for Raditz. He starts off as a bit of a villain, but through interactions with Bardock (either as a memory or some kind of spirit guidance) and Goku's influence, he changes his ways. They could all be training together on Planet Vegeta before its destruction, with Bardock teaching them valuable Saiyan combat techniques and life lessons that shape them into the characters we know.
A possible plot could be that Android 18 and Goku are thrown into an alternate dimension where they have to rely on each other to survive. In this dimension, they face challenges that test their friendship and fighting skills. Android 18 might learn some of Goku's signature moves and Goku could learn more about the technology within Android 18.
One possible plot could be that Harry discovers he is a Kryptonian. He then has to balance his life at Hogwarts with his new - found powers. Maybe he starts to show superhuman abilities during Quidditch matches, like flying faster than his broom should allow.
A plot could be that their worlds start to merge. Sonic's world of Mobius, Naruto's Hidden Leaf Village and Goku's Earth start to blend together. Sonic has to deal with the strange new chakra energy, Naruto is fascinated by Sonic's speed and Goku is intrigued by Naruto's unique jutsus. They have to figure out how to separate the worlds again while also fighting off threats that emerge from the chaos of the merging worlds.
One possible plot could be that when Goku and Goku Black fuse, they create a being with an incredibly powerful mix of Goku's pure heart and Goku Black's dark power. This new being might initially struggle with the conflicting natures within. They could then face an even greater threat than before, like a new, super - powerful villain that neither Goku nor Goku Black could have defeated alone. As the fused being, they have to learn to control their power and find a balance between good and evil within themselves to defeat this new enemy.
A plot might involve Goku accidentally stumbling into Zeno's realm. Zeno, who has only seen beings either fear or revere him, is amused by Goku's lack of fear and his eagerness to spar. So, they start a friendly sparring match that has the potential to either create chaos in the multiverse if they go all out or lead to a new understanding between the two most powerful beings in the Dragon Ball universe.
