I'm not sure it can be considered a popular genre. Most fanfic readers are interested in relationships between characters from their favorite shows, movies, or books that are relatable in a more human sense. A 'bull x female' concept is quite out - of - the - ordinary and may not attract a broad audience.
One possible theme could be a sort of friendship or an unusual bond. Maybe the story could explore how the female character overcomes her initial fear or hesitation around the bull and they develop a unique connection. Another theme could be about the female's role in taking care of the bull in a pastoral or rural setting.
One common theme is the exploration of their different cultures. Iron Bull is a Qunari and Lavellan is an elf, so their cultural differences can create interesting conflicts and reconciliations in the stories.
Sure. Fanfic can cover a wide range of themes. In a non - adult bull x centaur fanfic, perhaps they are part of a larger group of mythical creatures. They could be working together to defeat an evil sorcerer. The bull might use its strength while the centaur uses its archery skills and intelligence. It's all about building an interesting story around their interaction without any inappropriate content.
A 'bull fanfic' is a type of fan - created fiction. Fanfic stands for fan fiction, which is written by fans of a particular work, like a movie, book, or game. In the case of 'bull fanfic', it might be related to bulls in some way. Maybe it could be set in a bull - fighting context, or it could be about bulls in a more fantasy - like setting, such as bulls with magical powers in a fictional world created by the fan writer.
You can try some popular fanfiction websites like Archive of Our Own (AO3). There are usually a large number of Dragon Age - related fanfics, including those about Iron Bull and Lavellan. Just use the search function on the site and type in 'Iron Bull x Lavellan' to filter out the relevant works.
One possible storyline is that the bull and the centaur are both guardians of a sacred place. They have to work together to protect it from dark forces. The bull could use its brute force to fend off physical attackers, while the centaur uses its knowledge of magic and strategy to outwit more cunning foes.
I really like the fanfic 'Iron Bull's Devotion to the Inquisitor'. It shows how Iron Bull's loyalty to the Inquisitor grows over time. There are some really sweet moments between them, like when they have private conversations under the stars after a long day of dealing with various threats to the Inquisition.
I'm not familiar with the exact plot of this 'to kill a bull naruto fanfic'. However, in Naruto fanfics, the plot often revolves around the existing world and characters. It might be that the bull is a magical or special creature in the Naruto world, and the act of killing it has far - reaching consequences. For example, it could anger a certain clan or disrupt the balance of nature in the ninja world. The characters involved might be Naruto himself or some other well - known ninja trying to navigate this difficult situation.
There could potentially be a 'harry gets pregnant by bull' fanfic out there in the vast world of fanfiction. However, it's not something that would be considered mainstream or in line with typical fanfic themes. It might exist in some more niche or experimental corners of the fanfic community, but I haven't come across it myself.
