Raiden and Ruby would be an interesting pairing. Raiden is a highly skilled cyborg ninja with his own set of morals and combat abilities. Ruby, on the other hand, is a young and determined huntress. Their interaction could be fascinating as they come from different worlds but share a passion for fighting for what's right. Raiden's experience could help Ruby grow, and Ruby's enthusiasm could inspire Raiden.
Jetstream Sam and Yang would be a great pair. Jetstream Sam is a flamboyant and skilled swordsman. Yang is a strong - willed brawler who uses her gauntlets. The contrast between Sam's elegant sword fighting and Yang's more brute - force combat style would create interesting dynamics. They could have some epic battles together against common enemies, and also some great exchanges of banter as they get to know each other.
One idea could be a crossover where the characters from Metal Gear Rising have to adapt to the world of RWBY. For example, Raiden could team up with Ruby and they could share their combat skills. Maybe Raiden teaches Ruby some advanced sword techniques, while Ruby shows Raiden how to use Dust in combat.
One idea could be a crossover where the characters from RWBY have to adapt to the high - tech, cybernetic world of Metal Gear Rising. For example, Ruby could be fascinated by the advanced weaponry and try to incorporate some of the technology into her Crescent Rose. Another idea is a story where the villains from Metal Gear Rising are somehow transported to the RWBY universe and cause chaos, forcing the RWBY teams to team up with the heroes from Metal Gear Rising to stop them. A third idea might be a character - study type of fanfiction, focusing on how a character like Raiden would react if he found himself in the RWBY world with its unique magic and Grimm threats.
Ruby and Church could be an interesting pairing. Ruby is young and idealistic, while Church is often sarcastic and has a more jaded view. Their interactions could be really fun to read. Another would be Weiss and Tucker. Weiss is from a high - society background and Tucker is, well, Tucker. The contrast in their personalities and upbringing would make for an engaging story.
Reinhardt and Yang would be quite a pair. Reinhardt is the fearless crusader with his rocket - powered hammer and shield, while Yang is a brawler with her gauntlets. They could have some epic battles side by side, and Yang could learn about honor and chivalry from Reinhardt, while Reinhardt could be impressed by Yang's tenacity and determination in the face of danger.
One of the most interesting pairings would be Reinhardt and Pyrrha. Reinhardt is a knight - like character in Overwatch, and Pyrrha was a very skilled fighter in RWBY. They both have a strong sense of honor. Reinhardt could teach Pyrrha some of his combat techniques from the Overwatch world, and Pyrrha could show Reinhardt some of the unique fighting styles in RWBY. Also, Widowmaker and Weiss could be an unexpected but fascinating pairing. Widowmaker's cold - blooded assassin nature could contrast with Weiss' more noble upbringing, and they could learn from each other in terms of combat and strategy.
Naruto and Ruby would be an interesting pairing. Naruto's positive attitude and never - give - up spirit could mesh well with Ruby's determination. They could both inspire each other in combat and in their personal growth. Another good pairing could be Sasuke and Blake. Sasuke's brooding nature and his search for power could be contrasted with Blake's own past and her fight for equality. They could have some deep conversations about their motives and past traumas.
One interesting pairing could be Thor and Yang Xiao Long. Thor is a powerful Asgardian with his hammer Mjolnir, and Yang is a brawler with her powerful punches. They could have some great fight scenes together, and also share stories about their respective families and how they became strong. Another pairing could be Black Widow and Blake Belladonna. Black Widow's stealth and combat skills combined with Blake's agility and ability to use her shadow clones would make for an interesting dynamic.
I think pairing Ruby Rose with a Volt Warframe would be really interesting. Ruby is all about speed and her scythe - wielding skills, and Volt is known for its speed - enhancing abilities. They could learn from each other's combat styles and become a super - fast duo on the battlefield.
John Wick and Ruby would be an interesting pairing. Ruby is young and full of energy and hope, while John Wick is a jaded and highly skilled assassin. Their interactions could be really cool, with Ruby learning some more hardcore combat moves from John and John learning about the power of friendship and hope from Ruby.
