I think characters like Jiraiya would be important. Since he was Naruto's mentor, he could help Naruto understand and control the power related to being the son of fury. And of course, Naruto's family members, even if they are not alive in the original series, could be explored in this fanfiction, such as his father who might have passed on this 'son of fury' trait.
It could be about Naruto's journey as the son of a powerful and angry figure. Maybe he has to deal with the expectations that come with such a heritage while also facing his normal ninja challenges in Konoha.
Well, 'naruto nine fury fanfiction' might involve a story where the power of the nine (could be related to the nine-tailed beast) is somehow connected to a great deal of fury. It could be a tale of battles and intense emotions in the Naruto world. It could also be that the nine represents nine ninja with extraordinary fury powers.
There could be. The idea of combining different fictional universes in fanfiction is quite common. However, it might not be a very mainstream concept. It really depends on the creativity of the fanfiction writers. Some might find the idea of Harry Potter being related to Thor Fury interesting and write about it, while others may not. So, you'd have to do some digging on the relevant platforms.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might be about Mito Uzumaki and some sort of fury - related situation in the Naruto universe, perhaps her showing great power or facing a difficult challenge.
One possible theme could be the struggle against inner demons, as the fury might represent the characters' internal struggles. Another could be the power of unity in the face of overwhelming fury.
It would be a wild mix. Maybe Harry would inherit some of Thor's powers like super strength or the ability to control lightning, on top of his wizarding abilities. His magical world and the world of Thor might collide, with him having to deal with both Hogwarts and the Asgardian politics perhaps.
One possible plot could be that Harry Potter, as the son of Nick Fury, grows up in the wizarding world but with an added sense of secrecy and strategic thinking inherited from Fury. He might use his father's espionage skills to uncover dark secrets in Hogwarts, like a new Death Eater plot. He could also have a unique way of using magic, combining it with the combat and intelligence - gathering tactics he learned from Fury.
The plot could be about Naruto being transported to the world of How to Train Your Dragon and stumbling upon a Night Fury. Maybe he tries to befriend it using his ninja skills.
A lot of fanfictions also focus on the concept of competition. Since Beyblade is all about battles and Naruto has its own ninja battles, in these fanfictions, there are often epic competitions where characters from both worlds compete against each other. This can lead to some really exciting and action - packed stories. It also gives a chance for the writers to explore how different fighting styles and strategies from Naruto and Beyblade would clash or complement each other.
