One great fanfiction could be where Rex and Mythra go on a journey to a hidden land in Alrest. In this story, they might face new and unique enemies, and their relationship could grow stronger as they rely on each other's skills.
A good Rex x Mythra fanfiction often focuses on their relationship development. For example, showing how they gradually understand and trust each other more.
Their relationship can be developed through shared adventures. For example, going on quests where they rely on each other's skills. Rex might need Mythra's combat abilities and Mythra could need Rex's determination and kindness.
One idea could be that Mythra and Rex have to team up to save their world from a new, powerful enemy. During their journey, they discover new powers within themselves and also realize their feelings for each other are deeper than they thought.
You could look for fanfiction that focuses on Mythra's adventures. For example, her battles against powerful foes or her journey to discover new lands.
The combination of two very different universes. Naruto is from a world of ninjas, with chakra and unique jutsu. Mythra is from a high - tech fantasy world in Xenoblade. When you put them together, it creates a lot of potential for unique stories. Writers can explore how their powers interact, like Naruto's shadow clones and Mythra's blade skills.
Since this is a made - up title for the purpose of this question, we can only assume that Rex is likely a character in the Star Wars universe. He could be a clone trooper, as there are many clone troopers named in the Star Wars franchise. Or he could be a new, original character created specifically for this 'story' who might be a smuggler, a rebel, or even a Jedi in hiding.
One common theme is their relationship. Writers often explore the complex bond between Pyra and Mythra, whether it's sisterly love or something more nuanced. Another theme could be their adventures in the Xenoblade Chronicles world, like facing new enemies or exploring uncharted areas together.
Well, you can try searching on fanfiction.net. There are often a lot of crossovers there. Maybe start by using the search terms 'naruto x mythra' directly on the site. You might find some interesting stories written by fans who are into this unique pairing.
Fanfiction often contains inappropriate and non - family - friendly content. I can't recommend such fanfiction. However, you can try to look for regular Mythra - themed fanfiction on some official and clean fanfiction platforms.
