It could be a rogue Uchiha who has turned against the clan's values. He might be jealous of Naruto's power and popularity, and decides to use his Uchiha abilities to create chaos in the ninja world. He could also be trying to revive an old and dangerous Uchiha - related technique that was sealed away long ago.
One option for the main character is an OC (original character) who has the spirit of Naruto inside him but looks like Link. He has the determination of Naruto and the adventuring skills of Link. In the harem, we could have Ino from Naruto. She's confident and has her mind - related jutsus. And from Zelda, Midna could be a part of it. She is a complex and powerful character. Another character could be Hinata. Her shy yet strong nature would add an interesting dynamic to the harem.
One possible plot could be that the main character, who has the abilities of both Naruto and Link from Legend of Zelda, finds himself in a world where he meets various female characters from both universes. They are initially wary of him but as he helps them with different challenges using his unique skills, they start to develop feelings for him. For example, he might use Naruto's shadow clone jutsu to help in a large - scale battle in the Zelda world, impressing the female warriors there.
One idea could be exploring an alternate universe where the Uchiha clan never faced the massacre. So, Sasuke grows up in a loving family environment within the clan, and Naruto befriends the entire Uchiha clan, leading to different power dynamics and alliances in the ninja world.
The Legend of Uzumaki Hiroto was a derivative work of Naruto, which told the story of Uzumaki Hiroto's growth and the stories of other characters. Uzumaki Boto Legend was different from the original Naruto Naruto Shimbun Legend, so it was considered an independent manga.
In a 'Naruto True Power Tsunade Fanfic', the author might be delving into Tsunade's mental and emotional strength as part of her true power. Tsunade has endured a great deal of loss in her life, and this could be shown to fuel her power. For example, her resolve to protect the village could be even stronger due to her past experiences. It could also showcase her training regime to maintain and enhance her power, and how she imparts her knowledge and skills to the next generation of ninjas in the story.
Besides Naruto and Sasuke, Sakura could also be a main character. She might use her medical ninjutsu skills in combination with the new magic elements. There could also be new characters introduced specifically for this fanfic that are masters of true magic and play important roles in guiding the original Naruto characters through this new world of magic.
No. In most Naruto fanfics, Naruto is still depicted as the selfless hero he is in the original series. He values his friends, his village, and the greater good.
Most of the time, Legend is not factual. It might incorporate some common themes or archetypes but is mainly crafted to entertain and engage rather than recount real-life happenings. There could be elements borrowed from history or folklore, but it's not a strict account of truth.
