Well, you could give Menchi a unique personality trait that isn't as explored in the original. For instance, make her secretly a huge fan of a particular type of music from a far - off land in the Hunter x Hunter universe. And this love for music somehow ties into her cooking, like she creates dishes inspired by the rhythm of the music.
Developing a really interesting backstory for her is a great way. Dive deep into her family history. Maybe her family has a long - lost recipe that is said to grant special powers to those who eat it. And Menchi is on a quest to find all the ingredients for this recipe throughout the series, which would add a whole new layer to her character and make your fanfic stand out.
Create unique character relationships. For example, make her have a complex relationship with a Pokemon she catches but then starts to care for in a strange way. Also, add unexpected plot twists. Instead of the usual hunt - capture - sell cycle, throw in some elements that change her path completely.
Another idea is a fanfic that focuses on Menchi's past. Maybe she had a mentor who taught her everything she knows about cooking and hunting for ingredients. The story could explore her relationship with this mentor, how she overcame difficulties in her training, and how those experiences shaped her into the tough examiner we see in the series.
You can try some popular fanfiction websites like Archive of Our Own (AO3). There's a large collection of Hunter x Hunter fanfictions there, and you might be able to find some specifically about Menchi by using the search function and filtering for the relevant tags.
One thing that can make such a fanfic stand out is the world - building. If it expands on the 'Hunter x Hunter' world, like creating new locations related to the Zodiac and Chimera Ant storylines. Another aspect is the character arcs. If the fanfic gives the Zodiac characters and Chimera Ant - related characters new and interesting development paths, it will be very appealing. For instance, a Chimera Ant character could start as a villain but then have a change of heart due to interactions with the Zodiacs.
Well, the atmosphere. Since the Dark Continent is supposed to be this extremely dangerous and mysterious place, a fanfic that can really capture that feeling stands out. It should have a sense of foreboding, like at any moment, something really bad could happen to the characters. And the pacing is important too. If it can keep the story moving forward, not too slow or too rushed, while still exploring the wonders and terrors of the Dark Continent.
A plot could revolve around Menchi's past. Maybe she has a hidden connection to a powerful group or a long - lost family member. This could lead to a story of self - discovery as she uncovers secrets from her past while still maintaining her role as a hunter and a food expert. She might have to face old enemies or make difficult choices regarding her new - found knowledge.
First, you need to be really familiar with both universes. Know the characters, their powers, and the rules of each world. For example, in Naruto, there are chakra and jutsus, while in Hunter x Hunter, there are Nen abilities. Then, come up with an interesting concept for your story, like a character from Naruto traveling to the Hunter x Hunter world or vice versa.
First, you need to do a lot of research on both RWBY and Hunter x Hunter. Know the characters, their powers, and the settings well. For example, understand Ruby's Crescent Rose and how it works in RWBY, and also how Gon's Jajanken works in Hunter x Hunter.
Develop a really unique OC. Give them distinct personality traits, like being extremely shy but having a hidden fierce side in battle. Also, create a detailed backstory for them that ties into the Naruto universe in an interesting way.
In order to make your Blood x Alice fanfic stand out, consider adding some cultural references or historical elements. If the original Blood x Alice has a certain time period or culture it's based on, expand on that. For example, if it has a medieval - like setting, research real - life medieval customs and incorporate them into the story. You can also play with different narrative structures. Instead of a straightforward chronological order, try a non - linear structure with flashbacks and foreshadowing. This will keep readers on their toes and make your fanfic more memorable.
