The main characters are often Naruto, as he is the focus of the mecha concept. Shikamaru could also be a main character in this type of fanfiction. He would be the strategist, trying to figure out how to best utilize the mecha Naruto in battles. Additionally, Orochimaru might be a character in some cases. He could be interested in stealing the technology of the mecha for his own evil purposes or trying to manipulate Naruto through it.
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.
I think Hinata could be an ally. She has always been in love with Naruto and would not stand by while he is in danger from Dark Naruto. Additionally, Shikamaru is smart and strategic. He might see the threat of Dark Naruto to the village and decide to assist Naruto, using his intelligence to come up with battle plans.
For Naruto, it would be a whole new experience. He'd be constantly trying to communicate with the mecha Kurama, learning its quirks. Shikamaru might be the one thinking about the strategic uses of mecha Kurama in battle. He'd be coming up with plans on how to best utilize it. As for Kurama, he could be in an internal struggle. Part of him would want to stay relevant in Naruto's battles, while another part would be curious about this new mechanical version of himself and how it could help Naruto in the long run.
Well, it could be about a dark version of Naruto having different goals and values from the original Naruto. Maybe the black Naruto wants to take over the Hidden Leaf Village by any means, while the real Naruto tries to stop him to protect his home and friends.
In some 'Naruto finds a mecha' fanfictions, the plot often involves Naruto using the mecha to fight stronger enemies. For example, he might face a new and powerful group of rogue ninjas that are too strong for his normal ninja skills. The mecha gives him an edge in combat, like having enhanced speed and strength. Also, sometimes the mecha has special abilities like energy shields which Naruto has to learn to use effectively.
The theme of adaptation is also quite common. Both Naruto and Hinata need to adapt to the existence of mecha in their world. Hinata might have to overcome her shyness in a more high - tech and dangerous environment, while Naruto has to figure out how to use his brash and bold style in mecha combat. This process of adaptation often leads to character growth in these fanfictions.
One interesting concept could be the combination of ninja abilities with mecha technology. For example, a mecha might be powered by chakra, allowing for unique combat capabilities. Another concept could be the use of Sharingan or Byakugan in the mecha's targeting systems. And some fanfictions might explore how different ninja clans interact with mecha, like the Uchiha's sharing their fire - style jutsu knowledge to enhance the mecha's weaponry.
Naruto is often a popular character in Naruto mecha fanfiction. His natural charisma and powerful abilities can be translated well into a mecha - related story. Sasuke is also a common choice, as his brooding nature and Sharingan abilities can add an interesting dimension to mecha battles. Kakashi could be another popular one, with his wide range of jutsu and strategic mind, he could be a great mecha pilot or mecha designer in these fanfictions.
Yes, there are quite a few. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Some works might combine Naruto's ninja world with mecha elements in really creative ways, like having Naruto pilot a mecha infused with chakra technology.
