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.
In fanfiction, Naruto and Sasuke might become friends when they have to protect someone important to both of them. Let's say it's a young orphan who reminds them of their own difficult pasts. Naruto's positive attitude and Sasuke's protective nature would kick in. They would work together to keep the child safe. Through this shared experience and the emotions it stirs, they start to see each other in a new light and become friends.
A possible plot could be that Naruto and Sasuke are sent on a diplomatic mission to another village. Along the way, they face many challenges like harsh weather and bandit attacks. Naruto's ability to stay positive and Sasuke's combat skills help them survive. During their journey, they have deep conversations about their dreams and fears. This new understanding of each other makes them realize they have more in common than they thought, leading to friendship.
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.
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.
