The theme of sacrifice also pops up. Since Reshiram is often associated with noble values, there could be scenarios where either the human or the female Reshiram has to sacrifice something for the other. It could be sacrificing personal goals, or in more extreme cases, even their own existence to save the other. This adds a lot of drama and depth to the fanfictions.
One common theme is adventure. Ash and Reshiram might go on a journey together to discover new Pokémon or solve some mystery in the Pokémon world.
A common theme is the power struggle. Given their different natures and powerful abilities, many fanfictions explore how kyurem and reshiram deal with the balance of power between them. Another theme is friendship or alliance. Despite their differences, they often come together in fanfictions, either out of necessity or a growing understanding of each other.
A common theme is friendship that evolves into something more. The human and female Lucario start off as comrades in some adventure or task within the Pokémon world, and over time, their bond deepens romantically.
A third common theme could be self - discovery. Ash is constantly growing and learning in the Pokémon series. With an anthro Reshiram by his side, he might discover new aspects of himself, his powers, or his place in the Pokémon world. The fanfic could also explore how Reshiram, as an anthro character, has its own journey of self - discovery and how their paths intertwine.
A common theme is cultural exchange. Since Sangheili and humans have very different cultures, exploring how they learn from each other can be interesting. For example, a human might learn about the Sangheili's honor - based system, and a female Sangheili could learn about human emotions.
A theme that might often show up is the idea of protection. The human might feel the need to protect the female charizard from harm, or vice versa. Also, there could be a theme of discovery. As they interact, they discover new things about each other, like the charizard's unique abilities and the human's hidden strengths. This type of fanfiction can also explore the concept of communication between a human and a Pokémon, which is not always easy in the Pokémon universe.
Love is a very common theme. Despite their differences, the female werewolf and the human often fall in love, which forms the central part of the story. Another theme is the struggle for acceptance. They have to deal with the fact that their relationship is not the norm in either of their worlds.
One common theme is the 'forbidden love' aspect. Since elves and humans are different races, there are often social or cultural barriers in their relationship. For example, in many stories, the elven society might look down upon a relationship with a human.
Well, in these fanfictions, a prevalent theme is the idea of overcoming prejudice. Humans might initially be afraid or hostile towards the female yautja, and vice versa. But as the story unfolds, they see past the exterior differences. Also, adventure is a common theme. They often embark on quests or face challenges together, like fighting off other alien threats. And of course, there's the theme of love or at least a deep emotional connection that defies the biological boundaries between the two species.
Love and companionship are also very common themes. Despite their differences, the female dragon and the human often fall in love. Their relationship is unique because it crosses species boundaries. This love can be a source of strength for both characters, allowing them to face external threats together and grow as individuals within the relationship.
