Franky & Robin
Their personalities are similar in some points, and complementary in others. They're both very intelligent, they're both silly (although Robin never speaks her silly thoughts out loud, differently from Franky). They're both mature and have a parental affection towards the other members of the crew. They contrast in Franky being flamboyant and outspoken, as she's quiet and reserved, and I think it goes well because she can have a lot of fun with him. Also, they share similar backstories, in which they've been chased as criminals when they weren't, and when she sees how Franky dealt with it in a different way than she did, he inspired her to not give up and to have faith in her nakama. They went through a lot together and after that, are seen together all the time.
(I don't see her with Zoro exactly because of their personalities. They don't really talk to each other, and Zoro may be smart but he's not intelligent. I don't see any mutual interests they could share.)
People like to claim Franky is not mature but while he is goofy he also takes care of people. His two little sisters Kiwi and Mozu, he stopped them from their downward tale spin of drinking. He straightened out a whole town of gangsters and taught them a productive skill to make a living. He looked after his town and defended them from bad pirates. He is also very responsible when it comes to the ship. He is definitely a guiding figure especially for Ussop. Robin and Franky are like the older guiding siblings of the crew. They try to point the others in the right direction but ultimately let them all live their own lives. Plus Franky catching Robin when they fell and that look they shared says it all.
They share a strong bond and many, many canon moments... they like the other's presence, or else they wouldn't be so close to each other all the time. They have a nice dynamic going on. Together with Luffy x Nami, they're the only couples between Straw Hats I can see happening at the end.
YES. DO YOU PEOPLE EVEN READ THE MANGA? HAVE YOU NOT SEEN HOW MANY ONE ON ONE MOMENTS THEY HAVE TOGETHER. EVERYTHING FROM WATER 7 UP TO THE CURRENT REPEATING MATCHING SHIRTS THAT ONLY THEY HAVE?
I love how their personalities contrasted each other. Franky being more brash and boisterous compared to Robin's reserved and graceful attitude. Despite this, they are linked by one of the most plot points in One Piece universe: the ancient weapons. Their past both revealed in the same arc, and bonded closer during the time they were captured. Not to mention the hints and ship teases Oda gives us -- especially with them being the parents in the Strawhat Family. Imagine Franky and Robin having coffee/cola in a sunny afternoon and casually talks about said weapon of mass destruction. Adorable!
Best Couple Ever! They are perfect for each other. They are also probably the closest thing to a canon couple in One Piece. They balance each other. Their relationship dynamic just beautiful and amazing. It should be higher on this list.
THEY'RE LIKE BEAUTY IN THE BEAST! NO, REALLY, THINK ABOUT IT! A QUIET BEAUTY WHO LOVES READING, AND A GIANT MUSCULAR MONSTROSITY, FALLING IN LOVE! IT'S BEAUTY AND THE BEAST!
I love this couple. I just feel like they born for each other. And they are very close too.
Best One Piece ship, their interactions prove everything
They just feel so right together
I do like your idea of Robin x Franky but Robin and Zoro is preferred for me. Although I am SUPER (get it? It's a pun) happy that everyone is not pairing Nami with everybody else since (no offense Nami fans) I hate her so much that it reaches to the Big Bang. Thank you for liking Robin, Robin fans! I love you!
They are always together looking after the straw hat crew. Similar age. Get along well together.
Franky and robin are the parents of the crew
Lol at ZoRobin fans who have to bash this pairing because it clearly is closer to canon than their pairing. - Yan_6
I don't like it but it is obviously happening in the manga.
I love all the ship teases though. Their moments in Enies Lobby, the balls-crushing, Franky catching Robin from falling (granted, Brook had a moment like this, too) Franky calling Robin their beautiful archaeologist, Franky sleeping on Robin's lap (and Robin allowing it), and the matching outfits (in dressrosa arc).
Not to mention the SBS where they're the mom and dad of the family.
I don't know, man. I feel like in the recent chapters, Oda likes to ship these two. This ship speaks more to me. I also ship Zoro x Robin, but Franky x Robin is more favorable.
Some good Moments, Favourite Robin ship
They are so perfect together! They have more moments than zorobin! why can't you see that! One of the BEST couples EVER, I ship them so hard and I want to see more moments of them! SUPER NICE COUPLE
Wow there is a LOT of age gap in this ship Robin is 10 years older! After time skip Zoro became 20 and Robin 30 this is never goanna work!
One OTP to rule them all. They are so canon it hurts. But in a good way.
My personal favourite you just can't hate these two for me best one piece couple EVER! - Lima73
Yes, yes YES! cute moments together and father-mother figures of the straw hat family
No way dude franky and robin not my robin chan
I think they are so cute! They don't realize they like eachother, and they contrast so well!
They're the best together, even Oda ships them... Mother and father, pilot and flight assistant, matching shirts at the end of Dressrosa. They're always drawn together, talking in the background. I think their personalities match quite well too, Franky is more mature than what we see at face value, he just don't take himself too seriously.
