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.
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 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.
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.
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.
Well, Bell Cranel is definitely up there. His determination and naivete make him a great character to put in different situations in a crossover. He can be the fish - out - of - water in a new world, which creates a lot of potential for story development. Hestia, as Bell's goddess, is also a popular pick. Her possessive and caring nature towards Bell can lead to some interesting relationship - building in a crossover. And let's not forget Ryuu Lion. Her calm and collected demeanor along with her combat skills can make her a formidable presence in a crossover fanfic, especially when paired with characters from other worlds with different fighting styles.
Sebastian is often a popular choice. His demonic nature and his loyalty (in a rather twisted way) to Ciel make him a very interesting character to cross over. He can easily interact with characters from other dark or supernatural works, and his powers and suave personality can add a lot to a crossover story.
