Who would be the most interesting character pairings in an RWBY and One Piece crossover fanfiction?

Luffy and Ruby would be an interesting pairing. Luffy's carefree and determined nature combined with Ruby's innocent yet strong - willed personality would create some great interactions. They both have a sense of adventure and are leaders in their own groups.

Naruto and Luffy would be a really interesting pairing. Naruto's determination and Luffy's carefree yet strong - willed nature would create a great dynamic. They could learn a lot from each other, like Naruto learning about Luffy's ability to make friends so easily and Luffy learning about Naruto's never - give - up attitude towards his goals.

I think Naruto and Usopp would make a great pair. Naruto's over - the - top, positive attitude could rub off on Usopp, who sometimes lacks confidence. And Usopp's creativity with his gadgets and lies could be useful in the Naruto world. Also, Kakashi and Robin would be an interesting match. Kakashi is super smart and a great teacher, and Robin is very intelligent and has a thirst for knowledge. They could share a lot of historical and cultural knowledge from their respective worlds. And then there's Gaara and Brook. Gaara's past of being an outcast and Brook's unique undead state could lead to some deep conversations.

Ichigo and Luffy would be a really interesting pairing. Ichigo is all about protecting his friends and family and has a strong sense of justice. Luffy is the same, always looking out for his crew. They both have powerful and unique fighting styles. Ichigo's swordsmanship and Hollow - influenced powers would contrast with Luffy's Devil Fruit - based stretching abilities. They could learn a lot from each other in terms of combat and leadership.

Robin and Gray would be a fascinating pairing. Robin's calm and intellectual demeanor paired with Gray's cool and often comical personality would create an interesting dynamic. Robin could be interested in Gray's ice - make magic and how it works, while Gray could be intrigued by Robin's Devil Fruit powers and her knowledge of ancient texts. Another great pairing could be Chopper and Happy. Chopper's medical skills and cute appearance along with Happy's flying ability and positive attitude would make for some really heartwarming and useful interactions.

Zoro and Piccolo would also make for an interesting pair. Zoro is a master swordsman always seeking to become stronger, and Piccolo is a powerful Namekian with great combat skills. They could have some intense training sessions together, sharing their knowledge of combat and power - up techniques.

One interesting pairing could be Zoro and Erza. Zoro is a master swordsman and Erza is also highly skilled with her swords. They could have epic sword fights and also teach each other new techniques. Sanji and Mirajane would also be an interesting pair. Sanji's chivalry and love for women could be an interesting contrast to Mirajane's powerful and sometimes mischievous nature. And then there's Usopp and Happy. Usopp's tall tales and Happy's love for fish and flying around could lead to some really fun and comical moments.

Nami and Ginny would be an interesting match. Nami's love for money and Ginny's fiery spirit could lead to some great interactions. Nami could teach Ginny about navigating the high seas and making smart financial decisions, while Ginny could show Nami some of the magic tricks that witches use. Also, Hagrid and Chopper would be adorable together. Hagrid's big heart and love for strange creatures would mesh well with Chopper's kind and curious nature. They could exchange stories about magical and unique animals in their worlds.

Natsu and Luffy would be a really interesting pairing. They both have an insatiable appetite and are fearless leaders. Natsu's hot - headedness combined with Luffy's carefree nature would lead to some hilarious and action - packed moments. They could also learn from each other's sense of loyalty towards their respective crews and guilds.

Naruto and Luffy would be a really interesting pairing. Naruto's determination and Luffy's carefree but strong - willed nature could lead to some great interactions. They both have big dreams and are leaders in their own ways. Another interesting pair could be Sasuke and Zoro. They are both very skilled fighters with a somewhat brooding nature. They could have some intense sword - versus - sword (or sword - versus - katana) battles and also learn from each other's combat styles.
