I'm not sure about a specific 'goku x kefla fanfic' to recommend. You could try searching on fanfiction websites like Archive of Our Own or FanFiction.net. There might be some interesting ones there.
One common theme could be the power dynamic between Goku and Kefla. Since they are both very powerful characters in the Dragon Ball universe, exploring how their powers interact and complement each other might be a theme. For example, in battles or training sessions.
Sure, there are quite a few. These fanfictions often take the strong and unique personalities of Goku and Kefla and weave them into a romantic narrative. Some might be more action - packed with their love story developing in the midst of battles and challenges, while others could be more about the quiet, tender moments between them. It really depends on the creativity of the author.
One idea could be a story where Goku and Kefla have to team up to face a new, powerful enemy that neither could defeat alone. They start off not trusting each other much, but as they fight side by side, they learn to respect one another's strength and fighting styles.
One common theme is the exploration of their power dynamics. Since both are powerful characters, fanfics often show how they compare and contrast in terms of strength. Another theme is the idea of mutual respect. They come from different backgrounds, and the fanfics usually depict how they learn to respect each other's values and abilities. Also, the theme of growth in their relationship is quite common. Starting from initial misunderstandings or indifference, they grow closer over time.
Another theme could be cultural differences. Naruto is from a ninja - based culture in the Hidden Leaf Village, while Kefla is from the Dragon Ball universe with its own set of values and ways of life. Fanfics might play with how they deal with these differences when they meet. It could lead to some humorous or thought - provoking situations. For instance, Naruto might be amazed by the technology in the Dragon Ball world, or Kefla could be intrigued by the ninja techniques.
Goku would be more likely. He is always open to new friendships and challenges. He has a curious nature and would be intrigued by Kefla's power. So he might approach her first to test her strength or just out of friendly curiosity.
You can expect a lot of creativity. Since it's fanfiction, the authors can play around with the characters' personalities and the Dragon Ball universe rules. Maybe Goku shows a more romantic side that we don't often see in the original series, and Kefla could be softened in some ways to fit the love story.
One popular Gohan x Kefla fanfic is 'A New Bond'. It focuses on how Gohan and Kefla gradually come to understand and respect each other. Their interactions start from a sparring match where they realize each other's strength and potential. Another great one could be 'Unlikely Allies'. In this fic, they are forced to team up against a common enemy and during the process, a unique connection forms between them. There's also 'The Meeting of Minds' which delves into the psychological aspects of their relationship, exploring how their different personalities complement one another.
I'm not sure about specific 'naruto x kefla fanfic' stories offhand. But you can try searching on popular fanfic platforms like Archive of Our Own or Fanfiction.net. They usually have a wide variety of fan - created stories for different crossovers.
