One common theme is adventure. The female character and Gallade might go on a journey together through the Pokemon world, facing challenges and making new discoveries.
One common theme is loyalty. They are both likely to be loyal to their trainers and to each other in the fanfic. Another theme could be the power of psychic abilities. Since they are both psychic - type Pokemon, the fanfic might focus on how they use their powers in different ways.
Love and attraction can sometimes be a theme as well, though not always in a romantic way. It could be more about admiration and respect for each other's skills as pokemon trainers. For example, the female character might admire Ash's determination, and Ash might be impressed by her unique training methods.
You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of Pokemon fanfictions, including those involving Gallade and female characters.
One common theme is friendship. Just like how a trainer and his Pokemon are friends, a male and female Lopunny can have a strong friendship in fanfiction. Another theme is adventure. They could go on quests together, like finding rare items or exploring new regions.
The description of Gallade's character is crucial. Since it's a Pokemon with unique abilities and a distinct appearance, the fanfic should do justice to it. For example, it could describe how Gallade uses its psychic powers in relation to the reader, or how its blade - like arms are part of their interactions. Also, a good plot that takes the relationship in an interesting direction, whether it's an adventure they go on together or a problem they solve, makes the fanfic great.
One common theme is empowerment. Female characters in these fanfictions often start as underdogs but grow to be strong trainers. For example, a girl might start with a weak female Pokemon but through hard work and determination, they become a powerful duo.
Friendship is a very common theme. The male reader and the female Pokemon often start as friends and then their relationship deepens. For example, they might go on Pokemon - hunting adventures together and rely on each other.
One common theme is loyalty. The female pokemon is often extremely loyal to her trainer, and this loyalty can easily turn into love. Another theme is protection. The trainer protects the female pokemon from harm, which deepens their bond. For example, in many fics, the trainer might save the pokemon from a Team Rocket attack.
One common theme is the power of friendship that evolves into love. For example, in many stories, the male human and the female pokemon start off as just friends or trainer - pokemon partners. Another theme is the acceptance of differences. Since they are from different species, they have to accept each other's unique qualities. Also, adventure is often a theme as they usually go on journeys together in the Pokemon world.
Growth is also a major theme. The male trainer might grow in his understanding of different aspects of Pokemon, like the emotional connection with them, because of the female fan's influence. And the female fan could grow in her confidence or knowledge about Pokemon training through her interactions with the trainer. It's a two - way street of development.
