Minato might also be a prominent character. As their teacher, he can influence the way Obito and Kakashi interact. In some fan fictions, he could be the one to help them resolve their differences or provide some crucial information about their past that changes their current situation.
Some fanfictions might explore the emotional aspect of their fight. For example, how their past friendship affects the battle. Maybe Kakashi hesitates to strike a fatal blow because of their shared history.
One great Kakashi x Obito fanfiction is 'The Bonds We Share'. It delves deep into their relationship, exploring how their past experiences shape their interactions in a post - war Konoha. It shows their growth and how they come to understand each other on a deeper level.
In some fan fictions, there might be a plot where Obito has a change of heart before a major battle with Kakashi. He could start to question his motives and the path he has chosen, leading to a very intense and emotional confrontation with Kakashi that is more about ideology than pure combat.
You could also check out Naruto fanfiction groups on social media platforms like Facebook. There are often enthusiasts who share and discuss their favorite fanfictions. Just search for relevant groups, join them, and then look for fanfictions about Kakashi vs Obito.
In such a fanfiction, the story could take a very dark turn. Naruto's ideals of friendship and peace might be severely tested. He could be forced to question his own beliefs as Obito and Madara have very different outlooks. Maybe Naruto would try to change their minds, but it would be extremely difficult as they are both very set in their ways of achieving a new world order through more extreme means.
A great fanfiction idea might be a story that delves into an alternate universe where Kakashi was the one who fell into the dark side instead of Obito. This would completely change their dynamic. Obito would then be the one trying to save his former friend, and it could explore themes of redemption and the power of their bond in a very different context.
Well, it's hard to say who the 'best' is as it depends on personal taste. But some popular authors might be those who really capture the essence of the characters. For example, there are authors who are great at writing Kakashi's calm and collected nature while also showing his inner turmoil. They can make his relationship with Obito feel very real and complex.
A fanfiction story could start with Naruto being in a desperate situation where he feels that the normal path to peace is not working. So, he decides to team up with Obito and Madara. At first, they seem to be working towards a common goal. But then, Naruto realizes that their means are too extreme. For example, he discovers that the Infinite Tsukuyomi they plan would take away people's free will. He then has to find a way to stop them while still maintaining some sort of alliance. This could lead to a complex web of relationships and power struggles within the group.
Sasuke is often a popular character in these fanfictions. He might play a role in helping Naruto against Madara or have his own motives during their battle. Kakashi can also be a prominent figure, perhaps using his Sharingan in a crucial moment to assist Naruto. Another popular character could be Hashirama, as his connection to Madara is a key part of the original story and can be further explored in fanfiction.
