Sasuke and Wolverine. Both are anti - heroes at times and have a dark past. Sasuke's sharingan could be compared to Wolverine's enhanced senses. They could have some epic battles together, and also learn from each other. Wolverine could teach Sasuke about survival in a different kind of world, and Sasuke could show Wolverine some of his ninja sword techniques.
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.
Hinata and Scarlet Witch. Hinata is a shy but strong - willed character, while Scarlet Witch has incredible powers but also a complex personality. Hinata's gentle nature might balance out Scarlet Witch's more volatile side. They could also combine their powers in unique ways, like Hinata using her byakugan to help Scarlet Witch aim her chaos magic more precisely.
