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.
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.
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.
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.
It's hard to say for sure. Goku in his Super Saiyan Blue form has incredible power levels. But Naruto in his Baryon Mode also has a huge amount of power. However, if we consider the potential of fusing their powers, it might be a character who combines the best of both worlds. Maybe a fusion of Naruto and Goku would be the most powerful. They could have the ki - based attacks of Goku along with the ninja techniques of Naruto.
It could be Sargeras from World of Warcraft. His immense power as a titan could be really hard for Naruto characters to deal with. He has the ability to destroy entire worlds and his magical power is off the charts.
