The Road Runner could be an interesting character to pair with Rango. Their different styles of movement, with Rango being more of a swaggering walker and the Road Runner being super - fast, could create some really fun and comical interactions. Another great pairing would be with Shrek. The contrast between Shrek's ogre - like nature and Rango's lizard self would make for a great story of two misfits coming together.
Goku Black could be an interesting character to pair with Gogeta. Their power levels are both high and their personalities are quite different. Goku Black is more of a villainous character, so the dynamic between him and Gogeta, who is a hero, would be full of tension. Another interesting character could be Saitama from One Punch Man. The contrast between Gogeta's complex power - up system and Saitama's one - punch - kill ability would make for an exciting crossover. And then there's Naruto. His ninja skills and determination paired with Gogeta's power would create a unique combination.
Gohan and Wonder Woman would be an interesting pair. Wonder Woman's combat skills and her connection to the gods could be a great match for Gohan's Saiyan powers. They could learn from each other's fighting styles and cultures.
Thor and Godzilla would be an interesting pair. Thor, with his god - like powers and his hammer Mjolnir, could potentially have a showdown with Godzilla. It would be a clash of different kinds of power - Thor's lightning and brute strength against Godzilla's atomic breath and massive size.
Black Widow and Monarch scientists would be an interesting pair. Black Widow is used to dealing with espionage and sneaking around. The Monarch scientists have in - depth knowledge about the Titans. She could help them in a more tactical way, like getting information from shady organizations that might be trying to use the Titans for their own gain. And the scientists could provide her with valuable information about the kaiju to help the Avengers in their fight.
Sherlock and Italy would be an interesting pair. Italy is often portrayed as a bit scatter - brained and carefree in Hetalia, which would contrast sharply with Sherlock's intense and focused nature. Their interactions could be both comical and lead to some interesting plot developments as Sherlock tries to get Italy to focus on the case at hand. Another interesting pair could be Sherlock and Germany. Germany's discipline and order could either clash or complement Sherlock's methods, and they could have a great dynamic when it comes to solving a mystery together.
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.
I think Naruto and Lucifer would be an interesting pair. Naruto's unwavering belief in good and his never - give - up attitude would contrast sharply with Lucifer's more cynical and self - centered nature. Their interactions could be full of tension and also moments of mutual understanding as they learn from each other.
Hellboy and Wolverine would be a really interesting pair. Wolverine's feral nature and regenerative abilities combined with Hellboy's brute strength and demonic heritage would make for some great action scenes. They could have some really cool banter too, with Wolverine's gruff attitude and Hellboy's dry sense of humor.
One interesting pairing could be Godzilla and Hulk. Both are powerful, almost indestructible forces of nature. They could have an epic battle at first, as they both have a tendency to lash out when provoked. But then they could end up teaming up against a greater threat, like a powerful alien invasion. Another great pairing would be Godzilla and Iron Man. Iron Man could use his technology to study Godzilla, and perhaps even try to create some sort of armor inspired by Godzilla's abilities. And Godzilla could provide a physical presence that Iron Man could rely on in a fight. Also, Godzilla and Thor could be a fascinating pair. Thor's god - like powers and connection to nature could be paralleled with Godzilla's own primordial power. They might have a mutual respect for each other's strength.
