I'm not sure specifically as there could be many different takes in such a fanfiction. It might be a creative story where Naruto is somehow related to Hela, perhaps exploring a new backstory for Naruto that involves elements from the world of Hela.
One good Naruto Hela fanfiction could be 'Naruto and Hela's Alliance'. In this, Naruto might find common ground with Hela, perhaps in their pursuit of power in different ways. They could team up against common enemies in the Naruto universe and the world of Asgard.
Well, I don't really follow 'Naruto and Hela lemon fanfiction' directly. However, when looking for such fanfics, you should first make sure the website you're using is reliable. Some platforms have a better curation of crossovers. You could also check if there are any fan communities dedicated to this specific crossover who might be able to point you in the right direction.
You could try looking on popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). These platforms usually have a wide variety of fan - created stories, so there's a chance you'll find the 'naruto son of hela fanfiction' there.
First, you need to understand the characters well. Naruto is all about his ninja way, his dreams, and his friends. Hela is a powerful Asgardian with a thirst for power. Then, think of a unique scenario like what if Hela landed in the Naruto world during a major battle? You can start from there.
One idea could be that Hela, being a powerful Asgardian, somehow gets transported to the Naruto universe. She could initially see the ninja as weaklings but then be impressed by their unique chakra abilities. For example, she might be intrigued by Naruto's Nine - Tails chakra and see it as a power source similar to her own in a way. Another plot could involve Naruto having to team up with Hela to fight a common enemy that threatens both their worlds, like an ancient evil that can cross dimensions.
Naruto's chakra - based powers and Hela's Asgardian magic could create some really cool combinations. For instance, Naruto could use his Rasengan and infuse it with some of Hela's dark energy that she can manipulate. This would make the Rasengan more powerful and have an added effect like being able to drain an opponent's life force slightly. Or Hela could use her ability to summon weapons and Naruto could use his shadow clone jutsu to multiply the number of weapons she summons, overwhelming their enemies.
One possible plot could be that Hela somehow gets transported to the Naruto universe. Naruto, being the curious and kind - hearted ninja he is, tries to understand her and her powers. They initially clash due to their different natures, Hela being used to ruling and Naruto believing in equality. But as they face common enemies, like a new powerful Otsutsuki threat, they learn to work together. Hela teaches Naruto some of her dark magic in exchange for Naruto's chakra control techniques.
Well, Naruto has shown time and time again that he can grow in power exponentially. He started as an outcast in his village and became one of the most powerful ninjas in the world. His ability to adapt and learn new techniques is remarkable. Hela, though, is a different kind of powerful. She has an innate, almost primordial power. If we consider a long - term scenario in the fanfiction, Naruto might be able to find a way to match Hela's strength. He could learn about her powers and develop new jutsu to counter her. But initially, Hela's power as a goddess would likely make her seem stronger. However, Naruto's indomitable will and the power of friendship (yes, it sounds cheesy but it's a big part of Naruto) could potentially tip the scales in his favor over time.
One possible theme could be the clash of different power systems. Naruto has his chakra - based powers and Hela has her Asgardian might. Their interactions in a fanfiction might explore how these powers interact. However, since this is a rather unique crossover, it's hard to say exactly what the main themes would be without actually reading a lot of such fanfics.
