Some common themes could be the blurring of boundaries between the Pokémon world and the human world. There might be elements of discovery, as the human and Espeon figure out how to navigate this unexpected situation. Also, themes of loyalty and protection could come into play, as they face the consequences of their relationship. But it's crucial to remember that this is a very far - fetched fanfiction concept and not based on real - world biology or relationships.
In the world of fanfiction, while creative and often exploring out - of - the - ordinary concepts, the idea of an Espeon (a Pokémon) and a human having a pregnancy is completely fictional and not possible in the real world. Fanfiction allows for such wild ideas to be explored for entertainment purposes, but it goes against biological facts.
One common theme could be the exploration of their relationship in a more domestic or family - oriented way. Even without the inappropriate aspects, it might focus on how they support each other during the pregnancy. Another theme could be the reaction of their friends in the wizarding world to this new development in their lives.
One common theme could be the struggle for co - existence. Even without the inappropriate aspects, the idea of predators and humans interacting is full of potential for conflict and cooperation. Another theme might be the exchange of knowledge, like how the advanced technology of predators could be shared or withheld from humans.
One common theme could be friendship. The human boy and the female mew might start as friends and go on adventures together.
Another theme could be the idea of acceptance. The reader may need to accept the monster's appearance or nature, and the monster may need to accept the reader's human qualities. This can lead to a deep emotional connection that is explored in the story. In many cases, they might face external opposition due to their differences, which they then have to overcome together. This creates a plot full of drama and emotional depth.
A prevalent theme is their growth over time. They start as young trainers with different attitudes. Ash is more impulsive and Gary is a bit more arrogant at first. But as the story progresses, they learn from each other. Ash might teach Gary about the importance of believing in your Pokémon wholeheartedly, and Gary could show Ash how to be more strategic. This growth in their characters and their relationship is often explored in non - inappropriate 'gary x ash' fanfictions.
Excluding any inappropriate content, some common themes in 'knuckles x tails' fanfiction could be adventure. They could embark on quests together, exploring new areas in the Sonic universe. Their camaraderie could also be a big theme, showing how they interact on a daily basis in the Sonic world. And perhaps a theme of mentorship, with Tails' intelligence sometimes guiding Knuckles or vice versa, in different situations within the fan - created stories.
Common themes could include their historical and cultural interactions. For example, how their different cultures have influenced each other over the years. It might also focus on their political relationships, like how they cooperate or compete in international affairs.
One common theme could be relationship building. Harry would be in the process of forming different kinds of relationships with the members of his harem. Another theme might be loyalty and jealousy among the harem members. They might compete for Harry's attention in a non - sexual way.
The theme of loyalty also often appears. Toothless is always loyal to Hiccup and vice versa. Fanfictions can play around with this loyalty in different situations, such as when they are faced with danger from other dragons or humans. This loyalty is a fundamental aspect of their relationship and can be a central theme in appropriate fanfictions.
