There are a few on Wattpad as well. Some fanfictions might focus on Naruto having the strength and courage similar to Beowulf. They could put Naruto in a situation where he has to battle a huge and terrifying beast like in Beowulf's story. It's all about how the author wants to blend the two very different universes together.
You can also try searching on Tumblr. Sometimes users post about or even link to naruto beowulf fanfiction. It might be a bit harder to find compared to the bigger fanfiction platforms, but there could be some hidden gems there with interesting interpretations of how Naruto's ninja world and Beowulf's heroic world could interact.
One popular Beowulf crossover fanfiction is 'Beowulf in the Modern World'. It imagines Beowulf transported to our time and facing modern challenges. Another is 'Beowulf and the Wizard's Realm', which crosses Beowulf with a magical wizard world. There's also 'Beowulf: The Space Adventure' that takes Beowulf to outer space and has him deal with alien threats.
One great Percy Jackson and Beowulf fanfiction could be 'The Quest of the Demigod in Beowulf's World'. In this fanfic, Percy might find himself transported to the time and place of Beowulf. He could use his demigod powers to face the same monsters that Beowulf did. Another interesting one could be 'Beowulf and the Camp Half - Blood'. It could explore what would happen if Beowulf ended up at the demigod camp and had to interact with the modern - day demigods.
There's a fanfiction where the characters from 'Game of Thrones' encounter a creature similar to Grendel from 'Beowulf'. In this story, Jon Snow has to face this beast in a frozen landscape much like the North in 'Game of Thrones'. It's an interesting take on how the two different fictional universes could collide.
One great 'Game of Thrones' and 'Beowulf' fanfiction is 'The North Remembers: A Beowulf -esque Adventure in Westeros'. It combines the epic feel of Beowulf with the complex politics of Game of Thrones.
It could be really interesting. Maybe Naruto has to fight a monster like Grendel in the Hidden Leaf Village. He would use his ninja skills in place of Beowulf's brute strength. For example, instead of ripping off a monster's arm with his bare hands like Beowulf, Naruto might use his Rasengan to blow off the monster's limb.
One common theme is heroism. Both Naruto and Beowulf are heroic figures in their own right. So in fanfiction, it often focuses on how Naruto, with his own set of ninja skills and values, can exhibit the same kind of heroism as Beowulf. Another theme could be the battle against great evil. Beowulf fought monsters, and Naruto battles powerful villains in his world. Fanfictions might bring these two concepts together, like Naruto facing a new kind of monster - like villain inspired by Beowulf's foes.
One possible plot could be Naruto taking on the role of Beowulf in a world where the Nine - Tailed Fox is like Grendel. Naruto, with his indomitable spirit, would face the powerful and menacing Fox, using his ninja skills which could be paralleled to Beowulf's strength and courage. He might have to use his Rasengan as a weapon similar to how Beowulf uses his bare hands to defeat Grendel.
I'm not sure if there is such a specific 'Naruto is Beowulf fanfiction' out there. Fanfiction can be quite diverse and spread across many different platforms. You could start by checking some well - known fanfiction websites like FanFiction.net or Archive of Our Own, but it might be a very niche concept and not easy to find right away.
One popular 'naruto older naruto fanfiction' is 'The Legacy of Naruto'. It shows an older Naruto dealing with new threats to the Hidden Leaf. Another great one could be 'Naruto: The Elder Sage' where he has mastered new jutsus and is guiding the new generation.
One great Sage Naruto fanfiction is 'The Sage's Path'. It delves deep into Naruto's exploration of his sage powers. The story has some really interesting battles where Naruto uses his new - found sage abilities in unique ways, making for some exciting reading.
