One of the most interesting interactions would be between Weiss and Blake. Weiss, coming from a high - society background, and Blake, who has been an outcast, could have some really deep discussions about acceptance and change. Another interesting pair would be Ruby and Pyrrha. Ruby could learn a lot from Pyrrha's combat experience and Pyrrha could be inspired by Ruby's unique way of looking at the world.
I think Naruto and Weiss would have some great interactions. Weiss is from a high - class family and is very proper, while Naruto is this rough - around - the - edges ninja. Their clash of cultures could lead to some really funny and also some really deep moments. Maybe Weiss could teach Naruto about the importance of elegance in combat, and Naruto could teach Weiss about the value of hard work and determination from his own experiences growing up.
I think the interaction between Ruby and Ben would be really interesting. Ruby is very energetic and has a strong sense of justice. Ben, with his experience of using the Omnitrix to save the day, could share some of his stories with her. They could also have some friendly competitions regarding their combat skills, like who can take down a group of Grimm faster, with Ruby using her Crescent Rose and Ben using one of his alien forms.
Deadpool and Yang could also be really interesting. Yang is tough and has a bit of a hot - headed side. Deadpool would probably egg her on in fights, and she'd either be really annoyed or find his bravado kind of cool. They could have some epic battles together against the Grimm, with Deadpool making inappropriate jokes all the while.
In such a fanfiction, it could be a world where all the characters from RWBY get along peacefully. They might live in a big compound, sharing their skills and knowledge. For example, Ruby could be teaching the others some of her unique combat moves, while Weiss could be helping with more academic or strategic aspects. They'd face challenges together as a united front, without the heartbreak of losing any of their comrades.
Definitely Iron Man and Ruby. Ruby is young and full of enthusiasm, while Iron Man is a genius billionaire. Their interactions could be really fun as Ruby would be in awe of his technology, and Iron Man would be impressed by Ruby's determination and natural combat skills. He might even see her as a little sister figure and mentor her in some ways.
Another interesting interaction could be between Red Hood and Blake. Blake, with her Faunus background and her own complex views on justice, could have some really deep conversations with Red Hood. They might debate on when it's okay to take extreme measures in the name of justice.
I think Axel and Yang would have a cool interaction. Axel with his pyro abilities and his somewhat edgy personality could clash and also bond with Yang, who is hot - tempered and has her own fire - based powers. They could have some great banter and also team up in battles, with Axel using his acrobatic fighting style and Yang using her brawler moves.
Naruto and Ruby would be really interesting. Ruby is young and full of energy, much like Naruto. They could bond over their shared enthusiasm for protecting others. Naruto could show Ruby some of his cool ninja moves, and Ruby could introduce Naruto to Crescent Rose. Another interesting interaction would be between Sakura (from Naruto's harem) and Weiss. Weiss is from a wealthy family and is very proper, while Sakura is a strong - willed medical ninja. They could have some really fun arguments and also learn from each other's skills.
Ruby and Church would be really interesting. Ruby is all about being positive and leading her team, while Church is sarcastic and often a bit grumpy. Their different personalities could lead to some really funny exchanges. For example, Ruby might be excited to show Church her scythe, and Church would probably make some snarky comment about how impractical it looks but then be amazed when he sees her use it.
Well, Ruby and Weiss might start off bickering as usual at first. But as the situation gets more dire, they start to rely on each other. Weiss could use her summoning skills to help Ruby in combat if they face any threats while trapped. Blake and Yang would have a more sisterly bond. Yang would be protective of Blake, and Blake would use her intelligence to help Yang make better decisions.
