Definitely Eleven and Captain America. Steve's leadership and moral compass combined with Eleven's raw power would be a great combination. They could inspire each other in different ways.
I think Hawkeye and Robin would make an interesting pairing. Hawkeye could teach Robin some archery skills, and Robin could show Hawkeye the ins and outs of Hawkins. They both have a kind of underdog quality that would make their relationship fun to explore. Also, Joyce Byers and Black Widow could be an interesting duo. Joyce's determination to protect her family and Black Widow's combat skills and spy training would create a strong female - led partnership.
I think Eleven and Bill would make an interesting pairing. Eleven has her telekinetic powers and has faced otherworldly threats in the Upside Down. Bill is the leader of the Losers' Club and is very brave. Together, they could lead their respective groups in a fight against the combined threats of the Demogorgon and Pennywise.
Another great pairing could be Richie and Dustin. They both have a sense of humor that they use to cope with difficult situations. Richie's quick - witted remarks and Dustin's scientific knowledge could create some really interesting interactions. They could be the ones who try to figure out the scientific or otherworldly aspects of the crossover, like how the powers in Stranger Things relate to the strange entity that is It. Plus, their banter would be really entertaining.
Betty and Eleven would make an interesting pair. Betty has her own dark secrets and determination in Riverdale, and Eleven has her powers and a past full of mystery in Stranger Things. They could help each other out in different ways, like Betty helping Eleven understand normal human relationships, and Eleven using her powers to protect Betty when she's in danger.
Definitely Harry and Eleven. Harry has his own special powers in the wizarding world, being able to speak Parseltongue and having the power of love that saved him from Voldemort. Eleven has her telekinesis and other abilities. They could learn from each other. Harry could teach Eleven about the different types of magic, and Eleven could show Harry how to use her powers in a more creative way. Another interesting pairing would be Hermione and Dustin. They're both super smart. Hermione could introduce Dustin to the vast library of Hogwarts and all the knowledge it holds, while Dustin could share his knowledge of science and technology with Hermione, and they could come up with some really cool ideas that combine magic and science.
One interesting pairing could be Naruto and Thor. Naruto's exuberant personality and Thor's godly presence would make for an exciting duo. They both have strong leadership qualities. Another would be Sasuke and Black Widow. Sasuke's brooding nature and Black Widow's stealth and intelligence could create a great dynamic. They could learn from each other's combat and espionage skills.
I think Black Widow and Mulan would make an interesting pairing. Both are strong female characters. They could share their combat skills and stories of survival. Black Widow could learn some of Mulan's more traditional combat techniques, and Mulan could get tips on modern espionage from Black Widow.
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.
