The slugcat is often a popular choice. Its small and agile nature makes it interesting to pair with characters from other universes. It can bring a sense of vulnerability and tenacity to crossovers.
The scavengers are also quite popular. Their unique appearance and their own little society in 'rain world' can add a lot of flavor to crossovers. They can interact with other species in interesting ways, whether it's through trade or conflict.
The lizards can be a major focus in crossovers too. Their predatory nature can create a lot of tension when paired with characters who may not be used to such a harsh and dangerous predator. Their hunting skills and the way they move in the 'rain world' environment can make for exciting crossover scenarios.
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.
Well, if we consider other shonen - style series, someone like Naruto from 'Naruto' could be a potential crossover character. His ninja skills and strong will could create some interesting dynamics with the 'world trigger' characters.
One interesting concept could be the crossover of different species from 'rain world' with characters from other universes. For example, the slugcat interacting with a magical creature from a fantasy world.
Definitely Pikachu and Twilight Sparkle. Pikachu is one of the most iconic Pokemon, known for its cute appearance and electric powers. Twilight Sparkle is a central character in MLP, being very intelligent and powerful in magic. Their personalities are quite different, which makes for an interesting dynamic when they meet in a crossover fanfic. They could learn from each other, with Pikachu showing Twilight about the world of Pokemon battles, and Twilight introducing Pikachu to the magic of Equestria.
Sasuke is often a popular crossover character. His cool and brooding nature, along with his powerful Sharingan abilities, make him an interesting addition in crossovers. He could potentially team up with characters like Batman, given their similar dark and complex personalities.
The Avengers are very popular. Characters like Captain America and Thor are often paired with Spider - Man. Their different powers and personalities create interesting dynamics. For example, Captain America's leadership and old - fashioned values contrast with Spider - Man's youthful and sometimes impulsive nature.
Oy, the billy - bumbler, is a character that might be popular in 'the dark tower crossover fanfic'. His loyalty and his unique form of communication can add an interesting aspect to crossovers. In a crossover with a more action - oriented world, Oy could be used in unexpected ways, like helping the heroes in a battle with his sharp senses. Also, characters like Eddie Dean, with his street - smart nature and his role in the original story, can have new adventures and relationships in crossover scenarios.
One popular character could be the fearless warrior. This character is often strong and brave, leading the fight against the disasters in the burning world.
Of course, Naruto himself is very popular in these fanfictions. Writers often put him in situations within the Rain Village that test his beliefs and his ninja skills. For example, he might have to face off against a new and powerful enemy in the Rain Village while also trying to understand the complex politics of the village.
Definitely Loki. He's a fan favorite and can easily fit into various crossovers. His mischievous nature can add a lot of twists to a story. For example, if he were to cross paths with the Fantastic Four, he could play all sorts of mind games with Reed Richards while also being intrigued by Sue Storm's powers.
