Definitely not. Fanfiction communities generally focus on themes that are either based on existing popular media relationships (human - human) or on new relationships that are within the bounds of ethical and moral standards. The concept of a human - horse romantic relationship is far from what is considered normal or acceptable, and thus would not gain popularity.
I'm not sure specifically about 'Daenerys x Horse' fanfic. Fanfics can vary greatly in quality and content. You might try searching on some well - known fanfic websites like Archive of Our Own. They have a wide range of fan - created works, but it could be a bit of a search to find one related to this rather unusual pairing.
It is not appropriate. Ethical writing usually centers around relationships that are acceptable in society, like human - human relationships within the bounds of morality. This kind of 'fanfic' goes against the norms of what is considered proper in terms of relationships and can be disturbing to many.
It might also be a story with a more emotional or spiritual connection. The Milotic could represent something pure or powerful in the human's life. Maybe the human is in search of something, and the Milotic becomes a guiding force. In some cases, it could be a story about the human learning from the Milotic's grace and beauty, perhaps to become a better person or to find inner peace.
Xenomorph x human fanfic often explores unique and sometimes disturbing relationships. It might involve the contrast between the alien nature of the Xenomorph and the human characteristics. For example, some fanfics could focus on how a human might interact with a Xenomorph in a post - apocalyptic setting where they are forced to coexist. This could range from trying to understand the Xenomorph's behavior to forming an unlikely alliance.
Well, from an ethical point of view, it can be a bit of a gray area. On one hand, in the realm of fanfiction, it's a form of creative expression. But when it involves a 'human' and a Pokemon like Darkrai, it might seem a bit odd. Some people might argue that as long as it doesn't promote harm or inappropriate behavior, it can be okay. However, others may think it blurs the lines between the fictional and real - world concepts of relationships.
A theme of freedom could also be explored. Daenerys has always strived for freedom for herself and others. The horse could symbolize freedom in a way, like being able to roam freely across the land. And together, they could represent a new kind of freedom - seeking duo, with the horse carrying Daenerys to new places where she can spread her ideas of freedom.
I'm not sure if there is such a specific fanfic. Fanfic topics can be very diverse, but this combination seems rather unusual. You might have to search through various fanfic platforms very thoroughly to find it, if it exists at all.
It's not acceptable because it goes against the norms of human - animal relationships. Society has clear boundaries about the appropriate relationships, and this kind of concept blurs those boundaries in an unacceptable way.
The 'Sparkling x Human Fanfic' could also explore the idea of transformation. What if the human is somehow transformed into a sparkling - like being or vice versa? This would change their perspectives and relationships. They would have to deal with new abilities and limitations. For instance, if the human becomes sparkling, they might gain the ability to fly but lose their ability to communicate with other humans in the normal way.
