I think Negan and Loki would be an interesting pairing. Negan has his own brand of charisma and ruthlessness, and Loki is the God of Mischief. They could either be at odds, with Loki trying to manipulate Negan, or they could team up and cause all kinds of mayhem in both the zombie - ridden world and the superhero world.
Definitely Rick Grimes and Captain America. Rick is a natural leader in a world full of zombies, and Captain America is a symbol of leadership and justice in the Avengers world. They could share their leadership experiences and strategies to fight against the combined threats.
I think Cortana and Michonne would be an interesting pairing. Cortana has all this knowledge and intelligence, while Michonne is a fierce fighter. Cortana could provide strategic advice to Michonne, and Michonne could teach Cortana about the realities of survival in a world full of the undead. They could form a really unique bond.
Michonne and Sam Winchester would be a great pairing too. Michonne is a skilled fighter with her katana, and Sam is very intelligent and well - read. They could work together to research any possible links between the walkers and the supernatural. Sam could also help Michonne come to terms with any new, otherworldly threats they encounter.
Dean Winchester and Daryl Dixon would make an amazing pairing. Dean's tough - guy attitude and his skills with weapons combined with Daryl's survival skills in a post - apocalyptic world would be really cool to see. They could go on zombie - hunting trips together while also sharing stories about their pasts.
Sasuke and Daryl could be a really cool pairing. Sasuke's brooding nature and his powerful ninja skills along with Daryl's hunting and tracking abilities in a post - apocalyptic world. They might start off as rivals but eventually work together. For instance, Sasuke could use his Sharingan to detect hidden threats while Daryl uses his crossbow to take out zombies from a distance. And they could have some deep conversations about their past traumas and how they've coped with them.
Definitely the Flash and Iron Man. Tony Stark's high - tech gadgets and intelligence combined with the Flash's super - speed would make for some really cool scenes. They could work together on building some sort of super - fast vehicle or weapon. Another interesting pairing would be the Flash and Captain America. Steve Rogers' leadership and combat skills along with the Flash's speed could be a great combination for taking on enemies. The Flash could quickly get Steve into strategic positions during battles.
Inuyasha and Thor would be an interesting pairing. They both have a warrior - like nature. Thor with his hammer and Inuyasha with his sword could have some epic battles together against common enemies. They might also exchange stories about their different worlds and the powers they possess.
Definitely Captain America and Ikaris. Captain America represents the best of human values and leadership. Ikaris has his own strong sense of duty among the Eternals. They could bond over their similar leadership qualities and also learn from each other's different combat and strategic approaches. And then there's Hulk and Thena. Thena's combat skills and Hulk's brute strength could be a very volatile but also exciting combination when they face a tough enemy.
Definitely Naruto and Iron Man. Naruto is this energetic, determined ninja, and Iron Man is this brilliant, sarcastic inventor. Their personalities are so different yet they could learn a lot from each other. Iron Man could be intrigued by Naruto's chakra system and try to replicate it in some way, while Naruto would be fascinated by all of Iron Man's high - tech gadgets.
Supergirl and Black Widow would be a great pairing too. Black Widow could teach Supergirl some stealth and espionage skills, while Supergirl could show Black Widow the power of flight and super - strength. They could also bond over their experiences of being different in their respective worlds.
I think Thor and Wonder Woman would make an amazing pair. They both come from god - like lineages. Thor with his Asgardian powers and Wonder Woman with her Amazonian and divine powers could have some epic battles together against common foes. Their different yet powerful fighting styles would complement each other well.
