Rin Tohsaka and Rana Linchen would make for a fascinating combination. Rin's magical expertise and her confident personality could clash and then blend with Rana's energetic and somewhat impulsive nature. They could both learn from each other in terms of combat strategy. Rin could teach Rana more about magical control, while Rana could show Rin some new combat techniques from the Freezing world. Their relationship could be full of banter, competition, and ultimately friendship.
Another great combination could be Archer from Fate Stay Night and Kazuya from Freezing. Archer's cynical and experienced nature would contrast well with Kazuya's more naive and kind - hearted personality. In a battle situation, Archer's long - range archery skills combined with Kazuya's support abilities for the Pandora could create some really cool combat scenes. Plus, their different outlooks on life would lead to some interesting philosophical discussions between them.
Well, perhaps in this crossover fanfiction, the power systems of both could merge. For example, the magical abilities of the Fate Stay Night characters could combine with the Freezing characters' abilities. Let's say Saber's Excalibur could be enhanced by the energy manipulation skills of a Freezing character. And there could be a love triangle between a Fate Stay Night male character, a Freezing female character, and another character from either universe, which adds a lot of drama to the story.
Saber would be really interesting. Her noble and chivalrous nature would contrast with the rough - and - tumble world of Skyrim. She has a strong sense of justice and honor, which could put her at odds with some of the more morally gray characters in Skyrim. Her swordsmanship skills would be a great asset in a land full of combat, and her magical abilities could be a mystery to the mages of Skyrim. Also, her backstory as a king in her own world could lead to some really interesting interactions with the Jarls and other leaders in Skyrim.
One of the most interesting pairings would be Saber and Elsa. They are both strong female characters with powerful magic. Saber could teach Elsa about combat and leadership, while Elsa could show Saber how to better control her magic in a more natural way. Also, Kristoff and Lancer could be an unexpected but interesting pairing. Lancer's pride and Kristoff's down - to - earth nature would create some fun interactions.
It's really hard to say who would be the most powerful. On one hand, in Fate Stay Night, Servants like Gilgamesh have incredible power. His Gate of Babylon contains countless noble phantasms. But in the Naruto world, characters like Naruto in his Six Paths Sage Mode are also extremely powerful. He has the power of the tailed beasts and can use all kinds of powerful jutsu. However, if we consider a crossover, it might be someone who can combine the powers from both worlds. For example, if a mage from Fate could learn to use chakra and combine it with their magic, they could be very powerful. Or if Naruto could somehow gain the abilities of a Servant, like the ability to use noble phantasms, he would be unstoppable.
I think Harry Potter and Saber would make an interesting pairing. Harry has his own sense of justice and courage, and Saber is a noble and powerful Servant. They could learn from each other's leadership styles. Another good pairing could be Hermione and Rin. Both are intelligent and skilled in magic. They could exchange knowledge about their different magical worlds and maybe even come up with new spells or magical techniques together.
Weiss and Rin could be a great pair. Both are strong - willed and come from families with a certain reputation. Weiss's elegance in combat with her Glyphs and swordsmanship could be complemented by Rin's powerful magic. They might start off as rivals, constantly trying to one - up each other, but eventually realize they can achieve more by working together.
Another great pairing could be Rin Tohsaka and the Shield Hero. Rin is a skilled mage in the Fate universe. She could help the Shield Hero understand the magic in the Fate world, and in return, the Shield Hero could show her some of his shield - based techniques that might be useful in combat. Plus, their different personalities would lead to some interesting interactions.
The most interesting part is the combination of different powers. In RWBY, we have the unique Semblances and in Fate Stay Night, there are powerful Servant abilities. When these are combined in a crossover fanfiction, it creates really exciting battle scenarios.
I think Makoto Niijima from Persona 5 and Rin Tohsaka from Fate Stay Night would be a great pairing. Makoto is a strong - willed student council president, and Rin is a powerful mage. Their meeting could result in some intense discussions about leadership, power, and the use of their respective abilities. Plus, they both have a no - nonsense attitude which could lead to some interesting clashes and cooperation.
Saber is often a popular choice. Her noble and powerful image makes her adaptable to many different crossover scenarios. Archer is also a favorite. His cool and mysterious demeanor can add a lot of intrigue in crossovers. And Rin Tohsaka, with her intelligence and magical abilities, can easily be incorporated into various crossovers, like a crossover with a scientific - based universe where she uses her smarts to figure out new things.
