I like 'Naruto and Sasuke: A Different Path'. In this fanfic, their friendship is explored in a unique way. Instead of the usual storylines, it focuses on how they might have become friends in a more peaceful Konoha. They learn from each other's skills and share their dreams, which is really heartwarming.
A key element is the understanding between them. In fanfiction, they often show Naruto being able to understand Sasuke's pain and Sasuke coming to appreciate Naruto's unwavering loyalty. For example, in some stories, Naruto can sense when Sasuke is about to make a rash decision and stops him.
In many fanfictions, they might start by being forced to work together on a mission. They gradually see each other's true selves, like Naruto seeing Sasuke's underlying pain and Sasuke seeing Naruto's unwavering determination. This mutual understanding forms the basis of their friendship.
One common scenario is that they get trapped in a different dimension together. In this strange new place, they have to rely on each other to survive. Without the distractions of their normal lives and the expectations of the village, they really get to know each other on a deeper level and become best friends.
A fanfic could explore a scenario where Sasuke decides to teach Naruto some basic Sharingan techniques. Despite Naruto not having the Sharingan, Sasuke believes that Naruto's ability to learn quickly and his unique chakra could allow him to adapt some of the Sharingan's skills. This would strengthen their friendship as they train together and Naruto starts to understand Sasuke's power on a deeper level.
There's a fanfic where Naruto and Sasuke are secretly best friends during their travels. They meet up at various hidden locations. Sasuke helps Naruto with his chakra control in private, and Naruto in turn shares his food and stories with Sasuke. It shows a different side to their relationship, one that is based on mutual understanding and friendship.
Often, it develops through shared hardships. For example, they might be captured by a powerful enemy and have to escape together. During this time, they learn to trust each other more deeply.
The fanfic could be centered around Sasuke's best friends, Naruto and Sakura, and how they interact with Sasuke's Sharingan. For instance, Naruto might be curious about the Sharingan's abilities and constantly ask Sasuke to show him new tricks. Sakura, being a medical ninja, could study the Sharingan's effects on Sasuke's body to ensure he doesn't overuse it and harm himself.
In a fanfic like this, Sasuke's Sharingan could be the key to unlocking a hidden power within his best friends. Maybe his Sharingan has a special connection to Naruto's Nine - Tails chakra. As they fight side by side, Sasuke uses his Sharingan to guide Naruto in controlling the Nine - Tails better. Sakura, on the other hand, could learn new medical jutsu inspired by the insights from Sasuke's Sharingan, deepening their bond as they all grow stronger together.
A great Naruto - Sasuke friendship fanfic often has great dialogue. Their conversations should feel natural and reflect their unique relationship. They might argue like real friends do, but also have those deep, meaningful talks that show the strength of their bond. For instance, Naruto might crack a joke to lighten Sasuke's mood during a tough time, and Sasuke could respond with a rare smile, which shows their closeness.
