Well, a possible plotline is that Naruto discovers some secret techniques left behind by Tobirama that were meant only for his descendants. This could lead to a whole new arc of him training and mastering these techniques while also facing off against those who want to steal the techniques for themselves. Also, his family history might be explored more deeply, revealing secrets about the Senju clan that were long forgotten.
One plotline could be Naruto having to deal with the expectations and legacy of Tobirama. Since Tobirama was a great shinobi and one of the founders, Naruto might feel pressured to live up to that. Another could be the discovery of this lineage leading to new enemies targeting him.
There could be a backstory where Madara and Tobirama had a secret agreement that led to Naruto's existence. Maybe they foresaw a future threat and planned for Naruto to be born with their combined power to save the ninja world. Naruto would then have to uncover this mystery and fulfill his destiny.
Well, it depends on the specific fanfiction. Some fanfictions might make Naruto Tobirama's grandson to explore new storylines. For example, they could use this relationship to explain Naruto's strong chakra or his natural leadership skills. It could also be used to introduce new conflicts or alliances within the Naruto world that are not present in the original series.
Perhaps in this fanfiction, there's a secret prophecy about Naruto being the grandson of Madara and Tobirama. This leads to a lot of political intrigue within the village. Some people want to use Naruto for their own gain, while others are afraid of what his true heritage might mean for the future of the Hidden Leaf.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Naruto grandson of Tobirama' and you'll find a variety of stories with different plotlines, some might focus on his relationship with the Hidden Leaf Village, others on his unique jutsu inherited from Tobirama.
It's possible that Naruto would gain some of Tobirama's unique abilities. For example, Tobirama was able to create powerful water - based jutsu. Naruto might develop a new form of Rasengan that incorporates water elements or be able to use water - walking and other water - related skills without prior training. However, there could also be negative consequences. His body might reject the cells, leading to internal conflicts similar to what happened with some characters in the original series when they received foreign cells. This could make him ill or even temporarily lose his ability to use chakra.
One consequence could be a change in how Naruto is perceived in the village. Since Tobirama was an important figure, Naruto might be held to an even higher standard. Also, it could affect Naruto's relationships with other characters. For example, some might be more deferential to him.
Yes, there could be such fanfics out there. Fanfic writers often come up with creative family relationships that deviate from the original Naruto storyline. They might explore how Naruto's character would be different if he had such a relation to Tobirama. Maybe in these fanfics, Naruto could inherit some of Tobirama's unique jutsu or characteristics, which would add a whole new dimension to his character development and the overall story.
One plotline could be that Naruto, in his typical bumbling way, tries to impress Kurenai with his new jutsu or skills, thinking it'll make her like him. He might accidentally make a fool of himself in the process but still manage to charm her with his determination. Another could be that Naruto misunderstands some advice about showing respect to elders and ends up flirting with Kurenai thinking it's the right thing to do.
One possible plotline could be that Naruto discovers his connection to the Sannin later in his life. This new knowledge gives him access to hidden jutsu or knowledge that the Sannin had. For example, he might learn some unique medical ninjutsu from Tsunade. Another plot could involve Naruto facing enemies who are after the secrets that the Sannin might have passed down to him.
One possible plotline could be that the fused Naruto - Madara entity has to face an ancient evil that neither of them could have defeated alone. The combined powers of Naruto's positive energy and Madara's combat skills make for a formidable force. They might also struggle with internal conflict as Naruto's values clash with Madara's more ruthless nature.
