Another great pairing would be Sasuke and Wolverine. They both have a dark and brooding side. Wolverine's regenerative abilities and his adamantium claws could be compared to Sasuke's Sharingan and his various ninja weapons. They might start off as rivals, but eventually come to respect each other's skills in combat. Also, they could both share stories about their past traumas and how they overcame them to become the strong fighters they are today.
Alphys and Iron Man. Alphys is a scientist in Undertale who is a bit of a klutz but also brilliant. Iron Man is a genius inventor in Marvel. They could collaborate on some crazy technological inventions. Alphys could learn a lot from Iron Man about presenting herself more confidently, and Iron Man could be intrigued by Alphys' unique approach to science that comes from the Undertale world.
Supergirl and Iron Man would be an interesting pairing. Tony Stark could be fascinated by her Kryptonian technology and try to study it. Meanwhile, Supergirl would be intrigued by Stark's genius and his suits. They could have some really fun banter while saving the world from a new threat like Ultron who has incorporated some Kryptonian elements into his design.
Naruto and Spider - Man would be really interesting. They are both young heroes with a strong sense of justice. Naruto could learn some of Spider - Man's acrobatic moves and Spider - Man could be intrigued by Naruto's chakra - based powers. They could also bond over their experiences of growing up without parents in a way.
Batman and Iron Man would be a fascinating pairing. Both are brilliant inventors and strategists. They could compare their high - tech gadgets and suit designs. Batman's detective skills paired with Iron Man's scientific knowledge could make them a formidable duo in solving the mystery of some cross - universe threat. They might also argue about who has the better tech, which would be quite entertaining.
Wanda Maximoff and Juvia would be a fascinating pairing. Wanda's powerful magic and Juvia's water - based magic could create some really unique and powerful combinations. Also, their different personalities - Wanda's more brooding and Juvia's more love - struck - would make for some interesting interactions.
Link and Black Widow would be an interesting pairing. Link is a stoic hero with his own code of honor, and Black Widow is a trained assassin with a complex past. They could learn from each other's combat styles. Link could teach Black Widow some of his swordsmanship, and she could teach him some stealth and espionage techniques.
I think Thor and Chewbacca would be a really fun pairing. Thor with his god - like powers and hammer, and Chewbacca with his brute strength and loyalty. They could have some really comical moments together, like Thor trying to understand Chewbacca's growls and Chewbacca being in awe of Thor's lightning.
I think Harry Potter and Spider - Man would be an interesting pairing. They are both young heroes with a strong sense of justice. Harry could teach Peter Parker about magic, and Peter could show Harry how to use his web - slinging skills in a more creative way in the wizarding world.
The Arbiter and Thor. Thor is a powerful Asgardian with his hammer and lightning powers, while the Arbiter is a skilled warrior from the Halo universe. They could fight side by side against a common enemy. Their different cultures and fighting styles would make for an exciting combination. Maybe Thor could teach the Arbiter about magic, and the Arbiter could show Thor some unique Covenant combat techniques.
Another great pairing could be Sasuke and Griffith. They both have a certain level of ambition and a thirst for power. They might start off as rivals, constantly trying to one - up each other in terms of strength and influence. But as they face greater threats together, they could learn to respect each other and even form an uneasy alliance. It would be fascinating to see how their different motives play out when they are forced to work together.
