A common plot point is the culture shock. For example, Naruto characters being shocked by the dark and often cruel nature of the Overlord world. Another is the power - up concept. Naruto might gain new powers related to the Overlord's magic system. It makes for some really cool fight scenes.
One idea could be that Ainz Ooal Gown somehow ends up in the Naruto world. He could start by trying to understand the new world's power system. Maybe he'd initially be mistaken for a powerful jutsu user or a new type of tailed beast. Another plot could involve Naruto's friends being curious about Ainz's undead minions and trying to befriend them, while Ainz is cautious as he doesn't fully trust the inhabitants of this strange new world.
One popular 'naruto x overlord fanfic' is 'Naruto in the World of Overlord'. It combines the unique ninja elements from Naruto with the dark fantasy setting of Overlord in an interesting way. The story often has Naruto dealing with the power dynamics and strange creatures in the Overlord world, which makes for an exciting read.
In the Overlord world, Albedo could be one of the potential female characters. She is powerful and has a complex personality. In a harem fanfiction with Naruto, she might be intrigued by his different power system and his kind heart. Another could be Shalltear Bloodfallen. Her combat skills and beauty might make her interested in Naruto as well.
A third idea is a fusion of the two worlds. The shinobi villages and Nazarick could form a trade or knowledge - exchange system. Characters from both sides would have to learn about each other's cultures and abilities. This could lead to some really fun interactions, like Albedo trying to learn ninjutsu from Kakashi, or Sasuke being intrigued by the power of the Supreme Beings in the Overlord world.
Ainz Ooal Gown would be very interesting. His complex personality, with his mix of pride as an Overlord and his insecurities hidden beneath, would create a lot of depth. In the Naruto world, his reactions to the different values and cultures would be fascinating. For example, how would he deal with the concept of chakra compared to his own magic? And how would he interact with the ninjas who have such different combat styles and moral codes from his undead minions?
One idea could be that Naruto is somehow transported to the Overlord world and his unique abilities draw the attention of various female characters, leading to a harem situation. Maybe his ninjutsu skills are seen as a form of magic there.
Yes, there are likely some 'Naruto is Overlord' fanfictions out there. Fanfiction writers often like to combine different popular universes in creative ways. You can try searching on major fanfiction websites like Fanfiction.net or Archive of Our Own to find such works.
They can also act as a catalyst for character development. Characters like Naruto might be forced to re - evaluate their beliefs and goals. Naruto's usual ideology of never giving up and believing in the good in everyone could be severely tested. He may have to find new ways to deal with this 'overlord' who might not be swayed by his normal methods of persuasion. This struggle can lead to Naruto growing in ways that he hadn't before in the original storyline.
For Naruto characters in this fanfic, focus on their core traits. Naruto's never - give - up attitude can be a driving force. In the Overlord world, it could lead him to constantly challenge the status quo of Nazarick. For Overlord characters, like Ainz, emphasize his dual nature of being a powerful undead lord and also having his human - like insecurities. This can create interesting conflicts when interacting with Naruto's straightforward nature.
