Fanfiction about a Naruto character with a metal arm: Ideas for character development?

For a Naruto character with a metal arm, say it's a new and unknown shinobi. Maybe they were born into a family of blacksmiths who were secretly working on creating advanced weaponry. An accident during the creation of the metal arm led to the young shinobi losing their original arm. But instead of giving up, they decided to use the prototype metal arm. They then trained hard to master its use and became a force to be reckoned with in the Naruto world, using their unique arm to surprise opponents in battles.

Well, it could be that he got it as a gift from some super - advanced ninja technology group in the fanfiction world. Maybe they saw his need for an extra weapon or tool during battles and decided to equip him with a metal arm.

One special ability could be enhanced strength. The metal arm might be able to deliver much more powerful punches than his normal arm, allowing him to break through tough defenses more easily.

One idea could be to make the OC a healer. Since Naruto often gets into dangerous battles, a mother - like OC who can heal his wounds would add an interesting dynamic. The OC could have learned healing jutsu from a hidden clan. Another idea is to give the OC a tragic backstory, like losing her family in the war, which makes her protective of Naruto as she sees in him the hope for a better future.

Naruto could develop a darker side. Growing up with Batman, he'd be exposed to Gotham's crime and corruption early. But his Naruto - like spirit would still shine through. He might start using Batman's gadgets more efficiently than Bruce himself, adding a new dimension to his fighting style. For example, using smoke bombs in a more ninja - like way during battles.

This event would be a huge setback for Naruto. He's always been a very physical fighter, using his clones and his rasengan. Losing an arm would force him to adapt. Maybe he'd focus more on strategy and less on brute force. It could also make him more empathetic towards others with disabilities in the ninja world.

Naruto's character development in fanfiction can be quite diverse. He could be shown further maturing as Hokage, learning new leadership skills. Hinata, with her shy nature, might be depicted as becoming more assertive in fanfiction, especially when it comes to protecting her family and the village. Sakura, known for her strength, could be shown evolving her medical ninjutsu to new heights. In many fanfictions, we see these characters grow in ways that complement each other, like Naruto's optimism inspiring Hinata and Sakura to be more confident in their abilities.

A character in a Naruto Earth Release fanfiction could start as a weakling in Earth Release but through intense training and determination, they become a master. For instance, they might start by only being able to create small pebbles with Earth Release, but end up creating huge golems.

One idea could be to give the necromancer OC a tragic backstory. Maybe they lost someone dear and that led them to study necromancy in a desperate attempt to bring the person back. This could shape their personality, making them more brooding and determined. Another aspect could be their moral stance on necromancy. Are they using it for good, like bringing back fallen comrades to fight against greater evil? Or are they being tempted by the dark side of this power? Also, consider their relationship with the existing RWBY characters. They might initially be feared or mistrusted, but gradually earn respect through their actions.

Naruto may become more cautious. With a prosthetic arm, he realizes his vulnerability more. He might start to think more strategically before jumping into battles. For example, in a fight, he won't just rely on his brute strength but use the unique features of his prosthetic arm to his advantage.
