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.
I really like 'Obito's New Path'. In this fanfiction, Obito gets a second chance in a different reality. His Sharingan abilities are explored in unique ways, like how he uses it to understand the true nature of the ninja world. The story also has great character development for Obito and other Naruto characters.
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.
One idea could be a story where Female Kakashi and Obito are on a mission together in a mysterious land filled with ancient magic. They have to rely on each other's skills to survive and in the process, they start to see each other in a new light.
In some fanfictions, it could be due to a special jutsu gone wrong. Maybe a jutsu that Kakashi was using to transfer some of his chakra to Naruto for a mission accidentally transferred his Sharingan power as well.
Kakashi could use his Sharingan to analyze Obito's moves and find a weakness in his defenses. Since he has the Sharingan, he might be able to predict Obito's attacks and counter them effectively, eventually finding an opportunity to break free.
One popular 'kakashi in love with obito fanfic' is 'The Unspoken Bond' which delves deep into their relationship. It shows how Kakashi's feelings for Obito develop over time through various shared memories and new experiences they face together.
There's also 'Sharingan - Naruto's New Power'. In this fanfic, Naruto gets Obito's Sharingan in a rather unexpected way. The story focuses on his journey to master this new power. It has some interesting plot twists, such as Naruto having to face off against enemies who are specifically targeting him because of his newfound Sharingan ability.
In many 'naruto has obito sharingan' fanfics, a unique aspect is the new combat potential. Naruto already has his own powerful techniques, and adding the Sharingan gives him an edge in battle, like enhanced perception and the ability to copy enemy jutsu more effectively.
One great fanfiction could be about Kakashi using his Sharingan to train Naruto in a special jutsu. Maybe he shows Naruto how to better perceive an opponent's moves by using the Sharingan's ability to analyze. This could lead to Naruto developing a new and powerful technique that combines his own chakra control with the insights from the Sharingan.
