In a fanfic, it could really depend on the story's direction. If the story focuses on Boruto's growth and he unlocks the full potential of the Jougan, he could be the most powerful. The Jougan seems to have some mysterious and potentially very strong abilities. But Sarada could also become extremely powerful if she manages to awaken new levels of the Sharingan. Naruto, while powerful, may be surpassed by the younger generation in a story that emphasizes their rapid development.
No. Writing sexual fanfic involving underage or inappropriate relationships in the Naruto universe is completely unethical and violates the basic principles of respect for the source material and its intended audience, which often includes children and young fans.
It could be Naruto in his Nine - Tails Chakra Mode. He has immense power and speed, which would give him an edge in the Smash Bros battles.
It's hard to say for sure, but Naruto could be a very powerful character. His ability to use chakra and his vast array of ninja techniques like the Rasengan and Shadow Clone Jutsu would give him an edge. However, in the RWBY world, characters like Ruby with her Silver - Eyed Warrior powers also have great potential.
However, Jin Kazama from Tekken also has a strong claim. He has the Devil Gene which gives him enhanced abilities. He can transform into a more powerful form and has years of martial arts training. If he could somehow learn to control Naruto's chakra or ninja techniques, he could become extremely powerful. In a Tekken Naruto fanfic, it might depend on how the powers are combined and who has the better strategy in a fight.
It's hard to say for sure. Naruto, in his godlike state, has incredible power like being able to create and destroy on a large scale. But The Flash, with his ability to move at near - infinite speed and break the laws of physics in his own way, is also extremely powerful. It could be that Naruto is more powerful in terms of raw destructive power, but The Flash has the edge in terms of mobility and reaction time.
It's hard to say for sure, but Naruto at his strongest form, like in his Six Paths Sage Mode, would be extremely powerful. He has incredible speed, strength, and the ability to use all kinds of ninjutsu. In the Fate world, he could give a tough fight to many Servants. However, some of the really powerful Servants like Gilgamesh with his vast collection of powerful weapons and his god - like status would also be a strong contender.
I really like the fanfic 'Sarada's Ascent'. It shows Sarada facing various challenges in the Hidden Leaf Village. The author does a great job of portraying her determination and growth, making it an exciting read for any Boruto fan.
There may be some well - known fanfics with Boruto and Sarada kissing, but it really depends on which fanfic communities you explore. Some smaller, niche communities might have a fan - favorite that isn't as well - known in the larger Naruto/Boruto fanfic world. It could also be that new fanfics with this theme are constantly being written, so popularity can shift over time.
Sarada might develop a greater sense of self - reliance. When she travels through time, she may be on her own without the support she has in her own time. This would force her to trust her instincts more and become more independent.
Sasuke would be really powerful. His Sharingan abilities, along with his Rinnegan in later parts, would give him an edge. He could quickly analyze his opponents and use his powerful jutsu like Amaterasu and Susanoo in combat.
