One common plotline is Naruto being forced into battles against his will. Since he's treated like a weapon, the people in charge just send him into dangerous situations without considering his own desires. Another is Naruto trying to break free from being seen as a weapon. He might rebel against those who are using him and try to find his own path where he's valued as a person.
If Naruto is treated like a weapon in the fanfic, his character development might take a dark turn. He could start to view himself as just a tool, losing his sense of self - worth beyond his combat abilities. This might lead to him becoming more ruthless in battle, using any means necessary to achieve victory, as that's what a 'weapon' is supposed to do. However, it could also potentially lead to a redemption arc where he realizes he's more than that and fights to regain his humanity.
Well, in such a fanfic, it could be that Naruto is suddenly in the Fairy Tail world and the characters there mistake him for a baby. Maybe they try to take care of him in their own unique, Fairy Tail - style way. They might give him magic - infused baby food or put him in a crib made of enchanted wood.
Perhaps Naruto would be found by Fairy Tail members and they'd assume he was a lost baby. They'd start to take care of him, like Lucy might give him a warm place to sleep. Gray might try to cool down his 'baby food' if it was too hot with his ice magic.
Often, the main character who has dedicated their training to weapon specialization can be one of the most powerful. They might have unique abilities to handle and enhance weapons. Another could be an old, wise character who has years of experience in weapon crafting and using them in combat.
Well, generally in a 'naruto the weapon of god fanfic', the author could be exploring the idea of Naruto being bestowed with a weapon of god - like powers. This could potentially rewrite the power dynamics in the Naruto world. It might start with Naruto discovering this weapon in an unexpected place, like an ancient ruin. And then, as he starts to understand its powers, he has to deal with those who want to take it from him. His friends may or may not be aware of the full extent of this weapon's power and how it could change Naruto. There could be new villains emerging, attracted by the weapon's power, and Naruto has to use his new - found strength along with his ninja skills to protect the weapon and his world.
He could get angry. Harry has a strong will, and being treated like a baby would likely bruise his ego. He might lash out at the people doing it, shouting things like 'I'm not a baby! I've faced Voldemort!' to make them realize he's more capable than they think.
One key element could be a character who is like an emotionless weapon. In Naruto fanfic, this might be a new character or an existing one with a different twist. For example, they could be trained from a young age to be a killing machine without emotions. Another element could be the conflict this character faces in a world full of emotions like the Naruto universe. They might struggle to understand the bonds and values that other characters hold dear. Also, the plot could revolve around how this emotionless weapon - like character either changes or influences the Naruto world around them.
In 'naruto the weapon of god fanfic', Naruto is surely a main character as the title implies it's centered around him. His friends, such as Shikamaru, who is known for his intelligence and could play a role in strategizing around this new weapon. Also, villains from the original series or new ones created for this fanfic might be main characters as they could be after the weapon. For example, Orochimaru might be interested in the weapon's power for his own dark experiments. And Naruto's sensei, Jiraiya, could also be involved, perhaps guiding Naruto on how to use the weapon in a proper and responsible way.
Power growth is a common theme. The main character, with the help of the master, becomes stronger with the weapon. For example, they learn new jutsu related to the weapon.
