One idea could be that Naruto's positive and determined attitude clashes with Zeref's more dark and brooding nature at first. But as they form the guild, they learn from each other. Naruto could teach Zeref about the value of friendship and hope, while Zeref might introduce Naruto to more complex magic concepts. Maybe they create a guild that focuses on both physical combat skills like Naruto's ninja techniques and magical powers like Zeref's.
In this fanfiction, their guild could be a place for outcasts. Naruto, being an outsider in his own village at times, and Zeref, who is often shunned because of his dark powers, could create a guild where people with unique abilities are welcomed. They might have members from different worlds, including ninjas and mages. The guild would then have to deal with the politics and rivalries between the ninja and mage worlds.
The guild formed by Naruto and Zeref could have a very unique ranking system. Since Naruto is used to the ninja ranking system and Zeref has his own understanding of power hierarchies. They could combine the two. For example, there could be levels like Genin - for the new recruits with basic skills, then Chunin - those who have mastered a certain amount of magic or ninja skills, and finally Jonin - for the most powerful members. And at the very top would be Naruto and Zeref, guiding the guild with their combined wisdom.
One idea could be a story where Naruto has more control over his Four Tails form earlier than in the original series. He could use it to protect the Hidden Leaf in a new and unexpected way, perhaps by combining it with some new jutsu he's created on his own.
They could undertake missions to stop dark magic users. With Zeref's knowledge of dark magic and Naruto's combat skills, they would be well - equipped. For example, if there was a mage using forbidden spells to cause chaos, their guild could be called in to stop it.
Perhaps Naruto as a politician would advocate for a more inclusive ninja society. He could push for reforms in the ninja academy to accept students from all backgrounds, not just those with strong ninja lineages. He might also work on international relations, using his reputation as a hero to negotiate treaties and alliances with other ninja villages, ensuring that the interests of his own village are protected while also promoting mutual growth.
One possibility is that Naruto, with his determination, could adapt Zeref's powers in a unique way. Maybe he'd use Zeref - like magic to enhance his ninjutsu. For example, he could infuse Zeref's death - based magic into his Rasengan, creating a more powerful and dangerous attack. Another aspect could be Naruto's personality change. If he becomes influenced by Zeref, he might become more brooding and less of the cheerful ninja we know. However, his core values of friendship and protecting the village would still likely be there, just warped a bit by Zeref's dark nature.

In 'naruto beast form fanfiction', a cool concept could be the visual aspect of his beast form. Maybe it combines elements from different beasts he has encountered, like the Nine - Tails and other summons. This form could also have a different chakra signature that confounds his enemies.
In a fanfiction where Naruto becomes a cyborg, his appearance would likely change. He could have mechanical limbs that are sleek and powerful. His ninja way might also be affected. He might start to see himself as more of a weapon, but then realize that his humanity is still what makes him strong. He could use his new cyborg abilities to protect the village in ways he never could before.
One idea could be that Naruto gains some new power or jutsu that allows him to control Anko's actions in a non - malicious way. Maybe it's a form of genjutsu that he accidentally uses on her during a training session, and then has to figure out how to reverse it.
