Hulk and Olaf could be an unexpected but fun pair. Olaf's innocent and carefree nature could be a contrast to the Hulk's brute strength. Maybe in a fanfiction, Olaf could try to calm the Hulk down when he's angry. And Black Widow and Kristoff could be paired. Black Widow's stealth and combat skills could be combined with Kristoff's knowledge of the mountains and survival skills in an adventure - based fanfiction.
Oliver Queen (Green Arrow) and Black Widow are often paired. Oliver's combat skills with his bow and arrow combined with Black Widow's martial arts and espionage skills make for an exciting duo. They could be on a mission where they need to infiltrate an enemy base and use their complementary skills to succeed.
Well, Doofenshmirtz and Loki make an interesting pair in some fanfictions. Both are villains with a certain charm and a penchant for elaborate plans. They could scheme together to take over their respective worlds or cause chaos. Also, Perry the Platypus and Black Widow are a fun pair. Perry's stealth and combat skills can be compared to Black Widow's spy and fighting abilities. They could team up to take on their enemies, with Perry using his platypus - specific moves and Black Widow her martial arts and gadgets.
Spider - Man and Iron Man are really popular. They have a mentor - mentee kind of relationship in many fanfictions. Iron Man can offer his technological expertise to Spider - Man, and Spider - Man can bring his fresh perspective and street - level heroism to the table.
Peter Parker (Spider - Man) and Captain America are also quite popular. You can see stories where Captain America takes Spider - Man under his wing, teaching him about heroism and leadership. It's an interesting dynamic as they come from different generations of heroes.
Well, Spider - Man himself is obviously very popular. In the context of the crossover, his unique powers and relatable character make him a central figure. For Frozen, Elsa is often a popular choice. Her ice powers and her journey of self - discovery can be really interesting to combine with Spider - Man's story.
Snorunt and Glalie are often popular. Since they are ice - type Pokémon, they fit well into the frozen theme. Trainers who specialize in ice - type Pokémon like Candice from the games are also common characters as they can bring in their knowledge of the cold and ice - type Pokémon behavior.
Mulan and the twins from 'Twitches'. Mulan is a brave and resourceful warrior. The twins have their own unique magical abilities. They could team up in a battle against an evil force that is threatening both their worlds. Mulan could teach the twins some combat skills, and the twins could use their magic to give Mulan an edge in battle, like creating magical distractions or enhancing her weapons.
Inuyasha and Ariel would be an interesting pair. Inuyasha is a rough - around - the - edges half - demon, while Ariel is a curious and adventurous mermaid. Ariel could be fascinated by Inuyasha's otherworldly appearance and his sword, and Inuyasha might be intrigued by Ariel's ability to swim and communicate with sea creatures. They could team up to face a threat that endangers both the sea in the Disney world and Inuyasha's forest in his world.
Tinker Bell is often very popular in Disney Fairies fanfiction. Her adventurous spirit and her skills as a tinker make her a great central character. Another popular one is Rosetta. Her love for nature and her sometimes - sassy personality give a lot of room for interesting storylines. Fawn is also well - liked, especially when it comes to stories involving animals and her special connection to them.
Anna and Han Solo would be a great pair. Anna is brave and impulsive, much like Han. Han could teach Anna some of his smuggler tricks, and Anna could show Han the importance of loyalty and family. They could go on adventures together in both the Star Wars and Frozen universes, facing challenges like the Empire's troops in one and the snow monsters in the other.
