What are some interesting ideas in 'naruto gunsmith fanfiction'?

The main characters can include the gunsmith, who might be an outsider to the traditional ninja world but has a unique skill set. Another could be a ninja who becomes the gunsmith's protector or partner. For example, Sasuke could be interested in these new firearms as a way to enhance his own power. And sometimes, there are original characters created specifically for the fanfiction, like a rival gunsmith who tries to outdo the main gunsmith in creating the most powerful weapons.

One interesting idea could be the combination of Naruto's ninja skills with mecha technology. For example, Naruto might use his chakra to power up the mecha in unique ways. Another idea could be the new enemies that are created specifically for this mecha - Naruto concept, like robotic shinobi that require different combat strategies compared to normal foes. Also, the design of the mecha Naruto itself can be really cool, perhaps with features inspired by the Nine - Tails.

One 'gunsmith horror story' could be about a gunsmith who accidentally drilled through an important part of a gun barrel while trying to install a new sight. This completely ruined the barrel and made the gun unsafe to fire.

One idea could be exploring the different types of chains in the Naruto universe. For example, chains that are made from chakra and have special abilities like restraining powerful foes or sealing jutsu. Another idea is to create a story where a new character has a unique chain - based fighting style that surprises everyone in the Hidden Leaf Village.

One idea could be a story where Naruto discovers a new way to combine the Rasengan with his Sage Mode. He could use the natural energy to enhance the Rasengan's power and create a more devastating attack. Maybe he teaches this new technique to his friends at the ninja academy to inspire the next generation.

One idea could be to combine Naruto's spirit of never giving up with the Braveheart theme of fighting for freedom. Maybe Naruto could find himself in a situation where the Hidden Villages are under the control of an oppressive force, and he has to lead a rebellion, much like William Wallace in Braveheart.

One idea could be a crossover where Naruto and Vegeta end up in a shared universe and have to team up against a common enemy. Maybe a powerful demon or an evil alien force. They would have to learn to combine their unique fighting styles, with Naruto's ninjutsu and Vegeta's Saiyan power.

Another idea is to create a story where Naruto discovers an ancient oto-related secret that has been hidden for generations. This could involve him going on a quest, meeting new characters who are also interested in the oto, and having to protect the secret from those who would misuse it.

One idea could be to explore different character backstories more deeply. For example, give more details about Sasuke's life before the Uchiha massacre. Another could be to change the power - up systems, like making the Sharingan have new and unique abilities. And also, you could rewrite the relationships, maybe making Naruto and Sakura closer friends from the start.

A more complex idea would be to have a fanfiction set in a post - war scenario in both worlds. Naruto has finally achieved peace in his world, and Toriko has explored most of his world's ingredients. They meet through some sort of interdimensional rift. Together, they start a new journey to explore other dimensions in search of new things, be it new forms of power or unique ingredients.
