A good approach is to also check out fanfiction review blogs or YouTube channels. Some bloggers and YouTubers review fanfictions in these specific fandoms. They can give you insights into which ones are well - written, have interesting plots, and stay true to the characters. Additionally, follow the authors you like. If you find a great Shirou Nikos fanfiction, check out the other works of the author. Chances are they'll have more stories in the same vein that you'll enjoy.
Social media platforms can be useful too. Look for Fate RWBY groups on platforms like Reddit or Facebook. Post a question asking for the best Shirou Nikos fanfictions. People are usually quite helpful in these groups and will share their favorite reads. Also, when you start reading a fanfiction, look at the comments section. If other readers are raving about it and saying how it's one of the best, it's likely a good one to check out.
You can start by looking on popular fanfiction websites like Archive of Our Own or FanFiction.net. Use the search function and type in 'Fate RWBY Shirou Nikos'. Then, you can sort the results by popularity or rating. Another way is to join fan communities dedicated to Fate, RWBY, or both. Ask fellow fans for their recommendations. They might know some hidden gems that are not as easily found through general searches.
One great Shirou Nikos fanfiction could be one that focuses on his character development within the unique world of Fate and RWBY. It might explore how his skills from the Fate universe interact with the RWBY setting. For example, his swordsmanship could be a key element in battles against Grimm. Another fanfiction could center around a relationship between Shirou and Nikos, delving into how they support each other in their respective quests. There could also be a fanfiction that places Shirou in a new team with RWBY characters and shows how he adapts to the group dynamic.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). There are often tags related to both Shirou Emiya and RWBY that can help you narrow down the search. Another option is Fanfiction.net, which also has a wide range of stories. Additionally, checking out relevant forums and communities dedicated to either Fate/stay night (where Shirou is from) or RWBY can lead you to some great fan-created stories.
One great 'Fate Stay Rin x Shirou Fanfiction' is 'A New Dawn for Rin and Shirou'. It beautifully captures their relationship, showing how they support each other through various challenges. The author does an amazing job of staying true to their characters.
Another concept is a more comical crossover. Shirou tries to adapt to the different rules and magic in the Fate Apocrypha world. He constantly gets into funny situations as he misunderstands the local customs and magic systems. For example, he tries to cook using Apocrypha - style magic ingredients and chaos ensues.
One consequence could be that it attracts unwanted attention. Since Excalibur is a very powerful weapon, it might draw the notice of powerful villains in the RWBY world. Another consequence could be that it changes the power dynamics among the characters. If Shirou is suddenly very powerful with Excalibur, it could make other characters feel overshadowed or they might have to adjust their fighting styles to work with him.
In RWBY fanfiction, Shirou using Excalibur could be a very interesting scenario. Maybe he uses it in a way that combines his own sword - fighting techniques with the unique combat styles of RWBY. For example, he might incorporate some acrobatic moves like the characters in RWBY do while slashing with Excalibur. And he could use the power of Excalibur to break through tough Grimm defenses, given that Excalibur is often depicted as a very powerful weapon in its original context.
One common theme is the exploration of Shirou's character in the RWBY universe. How his skills and personality interact with the RWBY characters and the world around them.
I'd recommend 'Rin and Shirou: Love in the Chaos'. It's a really good one. It shows how their love can endure even in the most difficult of situations. The writing style is engaging and it really makes you root for the two of them.
One way is to adjust their power levels according to the new setting. For example, if a RWBY character enters the Fate world, their semblance might be toned down a bit to match the power scale there. Similarly, Fate characters in Remnant could have their magic restricted in some ways. Another way is to give them new abilities or limitations that balance them out. Maybe a Fate servant in Remnant can't use their full power because the magic in Remnant is different.
I'm not sure specifically as I haven't read this particular fanfiction. But generally, it might involve a story about Shirou in the RWBY universe under the theme of an 'oath' in a snowy setting. It could be about his adventures, relationships, or some kind of moral commitment he makes in that fictional world.
