One interesting scenario could be Naruto having to face multiple Akatsuki members alone and using new, unexpected jutsu. For example, he might combine his Rasengan with Sage Mode in a unique way to counter their attacks.
Konoha vs Akatsuki in a Naruto fanfic is a really interesting concept. Konoha represents the forces of good and order. They have a lot of resources and support from the village. Akatsuki, on the other hand, is a group of outcasts with unique and often extremely powerful abilities. In a fanfic, the outcome could be swayed by many factors. For instance, if the fanfic focuses on the power of friendship and teamwork in Konoha, they might prevail. But if it's more about the individual might of Akatsuki members, then Akatsuki could come out on top. Also, the presence of certain characters like Sasuke and his choices could greatly impact the result.
One key battle could be Naruto vs Itachi. Itachi is a very powerful Akatsuki member and Naruto has his own strong powers. Another might be Kakashi against Kisame. Kakashi is a skilled Konoha ninja and Kisame is a formidable Akatsuki member. Also, the fight between the Hokage of Konoha and the leader of Akatsuki would be crucial.
Inosuke doesn't become a Hashira in the manga. The story progresses with him having other significant experiences and achievements instead of achieving that specific position.
It's hard to give an exact number. Different story arcs and battles led to the deaths of multiple hashira. Some died heroically, while others met their fate in unexpected ways. The count changes as the manga progresses.
Definitely not. Genya remains outside the ranks of Hashira throughout the manga. This is because of a combination of factors such as his skills, experiences, and the overall direction of the story.
