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.
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 fanfiction, if Naruto ate the Kage Kage no Mi, he would gain the power to control shadows. This could make his combat abilities extremely powerful. He could use shadows to trap enemies, create illusions using shadows, or even use the shadows to enhance his speed and stealth in battles. For example, he could send his shadow to scout ahead unnoticed.
One idea could be a character from the Naruto universe obtaining the Kage Kage no Mi. They could use its powers to create shadow clones with unique abilities that are different from the normal shadow clones in Naruto. For example, these clones could have the power to manipulate shadows in ways not seen before, like using them to create illusions or even solidify shadows into weapons.
The Kage Kage no Mi's power can be used to disrupt the normal combat styles in Naruto. For instance, most ninjas rely on hand - to - hand combat, ninjutsu, and genjutsu. But with the ability to create and control shadows, a character can bypass these traditional defenses. They can use shadows to immobilize opponents or even drain their chakra, which would completely change how battles are fought and thus the power dynamics in the Naruto fanfiction world.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
