If Naruto ate the Suna Suna no Mi in fanfiction, it would change his fighting style drastically. He'd have to learn how to manipulate sand, which is a very different element from his usual chakra - based attacks. Maybe he'd combine his new sand powers with his shadow clones, sending clones made of sand to confuse his opponents. This would make him even more unpredictable in combat.
In some 'oc in suna fanfic', the oc has a special ability or power that is unique to the Suna setting. This power could be related to controlling the sand, like a different form of Gaara's power. The story then revolves around how the oc masters this power, deals with the jealousy or admiration of others in the village, and uses it to contribute to Suna's development or safety.
It could enhance his teamwork. With the power of the Suna Suna no Mi, Naruto could create sand barriers to protect his team members during battles. His new ability would add another layer of defense and offense to their group strategies.
Maybe the civilian OC is an artist who comes to Suna to seek inspiration. They end up befriending a group of local children and through them, learn about the hidden beauty and cultural traditions of Suna. However, there is a drought approaching, and the OC decides to use their art to raise awareness and funds to help the people of Suna prepare for it.
Well, there's a fanfic called 'Suna's Bond'. In this story, it shows the strong bonds between the Suna characters in Naruto. It's really interesting to see how they support each other. Then there's 'Suna's Secret Arts', which reveals some never - before - seen jutsu from Suna. Also, 'Suna's Rising Stars' is about the young and talented ninjas in Suna making a name for themselves.
First, create a detailed backstory for your oc. Think about where they came from in Suna, their family, and what events led them to become who they are. For example, if they are from a poor family in Suna, it could influence their goals and motivation.
One interesting Naruto Suna Anbu fanfiction could be about an Anbu member from Suna going on a secret mission in Konoha. They might encounter Naruto and his friends, leading to unexpected alliances and adventures.
He would surely meet Gaara. Gaara, having had his own experiences of being an outcast, would likely be one of the first to interact with Naruto. They could share their stories and become good friends.
Another possibility is a long - forgotten or hidden member of the Suna clan. They could have been shunned for their necromancer powers in the past but now, due to some events in the fanfiction, their powers are needed. This character could have a vendetta against Suna for being ostracized, or they could be a hero in disguise, ready to use their powers to save Suna from a great threat.
