Well, it's possible. The Naruto and Berseria universes are quite different, which makes the crossover an interesting concept for fanfiction. However, not all fanfiction writers may have explored this particular pairing. To find relevant fanfiction, try reaching out to fan communities on social media platforms dedicated to Naruto and Berseria. They may be able to point you in the right direction or even share some unpublished works they know of.
One possible plot could be that Naruto somehow gets transported to the Berseria world. He might have to learn the ways of that world, like the artes used in Berseria, while also trying to find a way back home. His ninja skills could be a unique advantage or a source of confusion in the new world.
In a Naruto and Tales of Berseria fanfiction, there could be a plot where the chakra system in Naruto is somehow connected to the Therion powers in Tales of Berseria. This connection could create a new type of power for the characters. For instance, Sasuke could gain some of the powers of a Therion, and his Sharingan could evolve in a completely new way, allowing him to see and manipulate the energy in a different manner.
One challenge is getting the characterizations right. In Naruto, the characters have very distinct personalities shaped by their ninja upbringing and the shinobi world's values. In Tales of Berseria, the characters are from a more medieval - fantasy setting with different moral and social norms. Blending these two different types of characters in a believable way can be tough.
One common theme could be adventure. Sonic is all about running around and having adventures, and Tales of Berseria also has a lot of journey - based storylines. So, in fanfiction, they might combine these elements for an epic adventure.
In this fanfiction, the Power Rangers could be facing a new type of threat that they can't handle alone. So, they use some kind of magic or technology to call for help from the Naruto and Tales of Berseria universes. The characters from those two worlds arrive and they have to learn to work together. The ninjas from Naruto can teach the Rangers some stealth and combat techniques, while the Tales of Berseria characters can offer their knowledge of magic and the use of artes. Together, they form an unlikely but powerful alliance to save all their worlds.
I'm not entirely sure if there is a specific 'Naruto can pole dance' fanfiction. Fanfiction can cover a wide range of ideas, from the most serious and in - character stories to the most out - there and zany concepts. Given the popularity of Naruto, there's a chance that a creative writer has explored this idea. Some platforms to look for it could be FanFiction.net or Archive of Our Own, but it may be a bit of a needle in a haystack.
I'm not sure about specific 'Tales of Berseria x Sonic' fanfiction off the top of my head. You could try looking on fanfiction websites like Archive of Our Own or FanFiction.net. Search for the keywords 'Tales of Berseria x Sonic' and browse through the results. Some might be really creative and well - written.
First, do your research on both universes. Know the characters, their personalities, powers, and the rules of their respective worlds. For example, in Fate Stay Night, understand how the Servant - Master relationship works, and in Tales of Berseria, know about the different artes and how they are used. This will help you create a more believable crossover.
In a fanfiction, Sakura could be the one to teach Naruto to pole dance. She has become quite skilled in various forms of combat and physical training over the years. She could introduce pole dancing to Naruto as a form of alternative training that focuses on different muscle groups and balance. And since they are friends, she would be patient with him during the learning process.
