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.
One possible fanfiction could be about their adventures in a new, uncharted land. Maybe they discover a hidden power that only they can unlock together. This power could be the key to saving their world from a new, unknown threat.
A good Rex x Mythra fanfiction often focuses on their relationship development. For example, showing how they gradually understand and trust each other more.
A simple plot could be that they encounter a powerful enemy that seems unbeatable at first. But through their combined strength and the unique bond between them, they manage to find a weakness and defeat the enemy. This would show how their relationship is not just about love but also about being a great team.
In my opinion, they're both great in their own ways. The story of Xenoblade Chronicles 1 was classic and engaging, while Xenoblade Chronicles 2 has its own unique charm and depth.
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.
Rex was originally a police dog trained for special tasks. His background involves various experiences that shaped his skills and instincts for solving crimes.
