I'm not sure of a specific 'naruto werewolf vampire hybrid fanfic' off the top of my head. But you can try searching on fanfic websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fan - made stories, and you might be able to find what you're looking for by using relevant keywords in their search bars.
There could be some really interesting concepts in a 'naruto werewolf vampire hybrid fanfic'. However, it's not a very common combination in the mainstream Naruto fanfic world. You might have to dig a bit deeper. Maybe start by looking at some Naruto crossovers with supernatural elements and then narrow it down to the werewolf - vampire hybrid aspect. For example, look for Naruto fics that involve other mythical creatures first, and then see if any of those touch on the werewolf - vampire hybrid idea.
One possible plotline could be that Naruto is somehow turned into this werewolf - vampire hybrid. He then has to struggle with new powers and instincts. For example, he might have the werewolf's enhanced strength and sense of smell along with the vampire's ability to hypnotize or super speed. And he has to keep this a secret from his friends in Konoha while also fighting against new enemies who are either after his new powers or are also some sort of hybrid or supernatural beings.
There could be a really interesting story where Naruto, with his ninja skills, adapts to being a vampire - werewolf hybrid in the Twilight world. Maybe he uses his shadow clone jutsu to confuse other vampires or werewolves. He could also bring in his own sense of honor and friendship from the Naruto universe into this new and dark world of Twilight.
Finding a specific 'naruto is a vampire lycan hybrid fanfic' can be a bit of a challenge. One thing you could do is to look for Naruto fanfic communities on Reddit.

One idea could be that the hybrid character has the speed and agility of a werewolf and the alluring charm and immortality of a vampire. They could be an outcast in both the ninja world and the supernatural world, trying to find their place. Maybe they use their unique abilities to protect the Hidden Leaf from threats that neither Naruto nor the normal shinobi can handle.
Well, Naruto is known for his big heart and loyalty. In this fanfiction, he might use those traits to bridge the gap between the vampires and werewolves. He could see that they don't have to be enemies all the time, just like he saw that there was more to people in his own world than just their differences. His hybrid nature could give him a unique perspective on their long - standing feud.
It could be a powerful vampire lord who sees the hybrid as an abomination and wants to destroy them. This vampire lord might view the mixing of werewolf and vampire blood as a threat to the purity of the vampire race.
One idea could be that Bella struggles to control her dual nature. Since she's a hybrid, she might have the speed and strength of a vampire and the heightened senses and connection to nature of a werewolf. For example, she could find it difficult to be around her human friends without accidentally revealing her super - human abilities. She may also face challenges within the werewolf and vampire communities as they might not fully accept her hybrid status.
A popular one is 'Hybrid Moon Rising'. In this story, the vampire werewolf hybrid is a key to a prophecy. The author does a great job of building the world around the hybrid, showing different vampire and werewolf clans' reactions to this new being. It's filled with mystery and a lot of cool supernatural elements.
One common theme is identity struggle. The hybrid is often caught between two very different species, not fully belonging to either. For example, in many stories, they have to hide their true nature from both vampires and werewolves.
One popular 'naruto vampire and werewolf fanfiction' is 'The Vampire's Jinchuriki'. It combines the Naruto universe with vampire and werewolf elements in an interesting way. The story follows Naruto as he discovers he has vampire blood and has to deal with the new powers and the challenges that come with it, including encounters with werewolves.
