A prevalent theme is the exploration of different cultures within the context of the crossover. Inuyasha comes from a Japanese - inspired feudal world, and Black Blood Brothers has a more modern, urban vampire setting. Writers often play with the contrast between these two settings, like having characters from one world adapt to the other. Also, the theme of family is common. Inuyasha has his complex family relationships, and the vampires in Black Blood Brothers also have their own family - like bonds, and these can be intertwined in the fanfictions. For example, a story might explore how Inuyasha's sense of family compares to that of a vampire clan in Black Blood Brothers.
One common theme is the clash of different supernatural elements. Inuyasha has his demons and magic from feudal Japan, while Black Blood Brothers has its own unique vampire - related lore. So, often in the crossovers, there's a exploration of how these different types of supernatural powers interact. Another theme could be the idea of loyalty and friendship. Characters from both series might form new alliances or have to deal with issues of trust.
Many of these crossovers focus on the power struggle theme. Inuyasha is constantly fighting against powerful demons, and in Black Blood Brothers, there are power hierarchies among the vampires. When the two worlds collide in fanfiction, there can be intense power struggles between different characters or groups. Additionally, the theme of redemption can be found. Characters who have made mistakes in their respective series might find a chance at redemption through their interactions in the crossover. For instance, a vampire who has done wrong in Black Blood Brothers might be influenced by Inuyasha's more straightforward sense of right and wrong and strive to make amends.
The theme of redemption can also be explored. Suppose a villain from Naruto's world ends up in Inuyasha's world. The different environment and the values of the people there might make them question their actions and seek redemption. It's an interesting way to give depth to otherwise one - dimensional characters.
One common theme is the clash of their different worlds. Jacob comes from a world of werewolves and vampires in the Twilight universe, while Inuyasha is from a feudal Japanese - inspired fantasy world. Writers often explore how they interact in a shared story space.
The theme of adapting to new environments is also quite common. Black Widow has to adapt to the strange and magical world of Inuyasha, and Inuyasha may have to deal with the high - tech and complex world of the Marvel universe if the story goes that way. This can create some interesting situations, like Black Widow trying to figure out how to use Inuyasha's sword or Inuyasha trying to understand modern technology like Black Widow's gadgets.

Archive of Our Own also has a great tagging system which makes it easy to find cross - over fanfictions between the two. There are often communities dedicated to such crossovers where fans share and recommend their favorite works.
Power and its implications can be a theme too. Their 'blood brother' bond might give them access to unique powers or make them a target for those who want to use their power. This can lead to a lot of conflict and drama in the fanfiction, as they have to deal with the consequences of having this special bond.
Some fanfictions might center around a particular event in the series and expand on it. For instance, the battle against the Kowloon Children. The author could add more details about the strategies, the emotions of the characters during the fight, and the consequences that followed in a more elaborate way.
There might be a Zelman fanfiction that focuses on his relationships. For example, his interactions with other main characters in the series. It could show a different side of him, like his loyalty or his conflicts within those relationships.
The 'Black Blood Brothers Light Novel' has themes like the coexistence of different races. The story depicts how different races interact, sometimes in harmony and sometimes in conflict. There is also a theme of redemption. Some characters may be seeking to atone for their past actions throughout the story.
One idea could be to cross it with a vampire - hunter themed story. The Black Blood Brothers could find themselves in a world where vampire hunters are more powerful and they have to team up with some unlikely allies to survive. Maybe a human detective who is initially after them but realizes they are not as bad as other vampires.
A lot of these fanfictions also deal with the concept of power dynamics. Koga is a strong demon, and Inuyasha is also quite powerful. When you add a female version of Koga, it can create interesting scenarios where they compete, cooperate, or both in different situations, which is often explored in the stories. And sometimes, they have to team up against common enemies while dealing with their own relationship issues.
