One common theme is power clashes. When different universes collide, the characters with their distinct powers often face off or work together. For example, in a crossover with another action - packed series, the mages from Fate Stay Night might have to deal with new types of combatants.
Perhaps a plot where the Holy Grail War from Fate Stay Night gets disrupted by the arrival of some key players from Fate Apocrypha. This could lead to new alliances and rivalries. Like Shirou from Fate Stay Night having to team up with a character from Fate Apocrypha, say Sieg, to face a common enemy that is after the power of the Grail in both their worlds.
One idea could be to have Naruto characters participate in the Holy Grail War. For example, Naruto himself could be a Servant, perhaps with his chakra being a unique form of mana. His skills like the Rasengan could be reimagined as powerful Noble Phantasms. Another idea is to put the Fate Stay Night characters in the Naruto world. They might have to deal with things like ninja clans and the politics of the hidden villages while also trying to find a way back to their own world.
One interesting concept could be the fusion of the Persona summoning system with the Servant system in Fate Stay Night. Imagine a character being able to summon both a Persona and a Servant, and how that would change the power dynamics and strategies in battles.
Sure. 'Fate/Grand Order and Fate/stay night: A Crossover of Epic Proportions' is quite interesting. It combines the elements of both very well, with unique character interactions.
I really like the fanfic 'Rin's Redemption'. It focuses on Rin's character development in a way that the original might not have fully explored. The plot is filled with twists and turns that keep you hooked from start to finish.
Rin Tohsaka from Fate Stay Night and Astolfo from Fate Apocrypha. Rin is a serious and intelligent mage, while Astolfo is a carefree and somewhat eccentric Servant. The combination of Rin's no - nonsense attitude and Astolfo's wacky behavior would make for some really interesting and humorous exchanges.
Yes, there are. You can find some on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Fate Stay Night crossover RWBY' and you'll get a list of fics. Some might focus on character interactions between the two universes, like how Saber from Fate Stay Night would interact with Ruby from RWBY.
In a crossover, the power systems would likely have to be balanced. The jutsu in Naruto are very different from the magic in Fate Stay Night. However, if a Fate character were to enter the Naruto world, they might find that their magic is affected by the chakra - rich environment. For instance, a mage's fire spell might be enhanced by the natural energy in the Naruto world. On the other hand, a ninja using chakra might find that they can learn some basic magic concepts from the Fate characters and use it to supplement their jutsu.
Well, one big challenge is combining the different power systems. In Fate Stay Night, you have magic and Servant abilities, while in Halo, it's all about advanced technology and physical combat skills. Figuring out how to make these two coexist in a believable way is tough.
