One reason is the unique take on Naruto's powers. Ultra Instinto gives a new dimension to his abilities, making battles more exciting. It allows for creative interpretations of his character growth. Also, fanfics in this genre often explore uncharted territories in the Naruto universe, like new relationships or different power hierarchies.
To write a great Naruto Ultra Instinto fanfic, start with a strong plot. Maybe something that revolves around a new threat to the Hidden Leaf Village that only Naruto's Ultra Instinto can counter. Develop his relationships with other characters in the context of this new power. Use vivid descriptions to bring the battles and the world of Naruto to life. And don't forget to proofread for grammar and spelling errors.
One possible plot could be that there is a rift in the multiverse that brings Goku and Luffy together in a strange new world. They initially misunderstand each other and start to fight. As the fight progresses, they both realize that there is a greater threat at hand that is causing the rift. So, they team up, with Goku teaching Luffy some of his combat techniques and Luffy showing Goku the value of friendship and loyalty in a different way.
The Goku Kefla hentai manga is likely to feature explicit and potentially offensive content that goes against the intended themes of the original characters and stories.
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.
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.
Goku in Ultra Instinct mode is extremely powerful. He has superhuman speed, strength, and can dodge attacks effortlessly. However, Luffy also has his own set of amazing abilities like his Gear Fourth form which gives him enhanced speed and power. But I think Goku would win because his combat skills and power level are just on a different scale compared to Luffy.
Well, it's really hard to say for sure. Ultra Instinct Goku is extremely powerful with his god - like reflexes and insane combat skills. But Fairy Tail characters also have some very strong magic. If we consider Goku's speed and strength, he might have an edge. However, some Fairy Tail mages could potentially use powerful spells to counter him. So it could go either way depending on how the fanfiction is written.
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.
