One common theme is the exploration of different worlds colliding. Since 'wolf's rain' has its own unique world with wolves and the concept of Paradise, when crossed with other fandoms, the contrast and combination of those worlds' rules and cultures are often explored.
One popular 'wolf's rain crossover fanfiction' is the one that crosses it with 'Fullmetal Alchemist'. In this crossover, the themes of both worlds blend interestingly. The wolves' journey for Paradise can be paralleled with the Elric brothers' search for the Philosopher's Stone in a way that creates a unique narrative.
Some less obvious but still popular crossover characters could include Professor Dumbledore. His wisdom and power could have a significant impact on the events in Wolf Rain's world. On the Wolf Rain side, Tsume might be used in crossovers. His tough - guy attitude and loyalty could lead to some really engaging storylines when he meets the characters from Harry Potter.
One common theme is the exploration of characters' hidden depths. In Harry Potter fanfiction, we often see more about the inner thoughts and feelings of minor characters like Neville Longbottom. In Wolf Rain fanfiction, it could be about the wolves' individual pasts. Another theme is the idea of a journey, whether it's Harry's journey to defeat Voldemort in a new way in Potter fanfic or the wolves' journey in Wolf Rain fanfic. And of course, there's often a theme of friendship or loyalty in both types of fanfiction.
The theme of loyalty also pops up a lot. Wolves are known for their loyalty in packs, and in fanfiction this can translate to loyalty between friends or comrades, whether they are wolves, humans or other creatures in the crossover.
One characteristic is the strong presence of nature. Since wolves are often associated with the wild, these novels usually have detailed descriptions of forests, mountains, and other natural landscapes. For example, in many such novels, the meetings between the human and wolf characters often take place in a beautiful forest setting, with the sounds of running water and birds in the background.
One interesting crossover could be the magical elements of Harry Potter being introduced to the post - apocalyptic world of Wolf Rain. For example, wizards using spells to help the wolves in their journey to find Paradise. Another could be a character from Wolf Rain attending Hogwarts and having to deal with the magical curriculum while also maintaining their wolf - like instincts.
A common element is often the integration of Blade Wolf's unique abilities. For instance, his speed and combat skills are used in crossovers to make him a formidable force. Another element could be his relationship with other characters from the crossovers. Maybe he forms an alliance or has a rivalry.
Imagine a story where the Deathly Hallows are in the Teen Wolf world. The Teen Wolf characters don't understand what they are at first. But then they team up with some HP characters who have come to retrieve them. They have to battle a powerful dark force that wants to use the Hallows for evil in the Teen Wolf realm. This would combine the magical elements of HP with the action - packed werewolf lore of Teen Wolf.
One popular Harry Potter fanfiction is 'The Draco Trilogy'. It offers a different perspective on the relationship between Draco Malfoy and Hermione Granger. For Wolf Rain fanfiction, 'Wolf's Heart' is quite interesting as it delves deeper into the characters' backstories. However, finding really good ones might require some searching on dedicated fanfiction websites like FanFiction.net or Archive of Our Own.
