Hana Hana no Mi

The Hana Hana no Mi, also known as the Hana Hana Fruit, is a Paramecia type Devil Fruit that allows the user to replicate and sprout pieces of their body multiple times from the surface of any object or living thing. "Hana" is the Japanese word for "bloom" and "flower", and reflects the nature of the user's power to sprout their body parts like a blooming flower. The fruit keeps its original Japanese name in the 4kids dub. It was eaten by Nico Robin.

The power of the fruit was first demonstrated but not clearly seen before Luffy and crew when they first met Robin on the Going Merry. The fruit's actual power was fully revealed during Robin and Pell's confrontation.

Strengths and Weaknesses
The fruit's major strength, as demonstrated by Nico Robin, is the ability to sprout multiple body parts on any surface except seastone. With this ability the user can take on many attackers by using many sprouted limbs. Since the user is practically the only one who knows where their limbs will sprout out, they have the element of surprise on their side. So unless an opponent is incapable being held, like being a Logia Devil Fruit user, or otherwise, any opponent that faces the user is practically defenseless against them, making this devil fruit one of the most powerful of the Paramecia class of Devil Fruits. Another strength is that the user can also create body parts like an eye in order to gather information.

Aside from the standard Devil Fruit weaknesses that a user falls prey to, the user of the Hana Hana no Mi has some weaknesses unique to themselves. The user will gain damage to their body if the extra limbs are attacked and can feel the pain. They can't create limbs where there is not enough room and while each part is capable of that parts normal movements, the body part itself is bound to where it was sprouted from. The strength of the user is also still limited to their individual strength. So even if they sprout hundred arms or more in order to aid in carrying something, they will still feel like they're carrying the load with their own two arms.

According to Oda, the user has a radius of 200 Hana Hanas in which they can extend parts of their body.

Usage
The powers of the fruit have been used by Robin for a variety of ways. She has been using as far back as she was a child. She most notably uses the powers for combat however she has been known to use them for other purposes.

Arms


Robin mostly uses the fruit's powers to replicate her arms in order to a variety things. The named techniques that Robin uses for her arms all follow a pattern. First, she says the number of arms she will sprout in spanish followed by Fleur, which means flower in french. From there, depending of where she sprouted her arms, she can do a number of things. If the thing she will do next is an attack, she will state the name of the attack in english. An example of this pattern is the technique, Treinta Fleur Strangle, wherein she sprouts thirty arms and then strangles her opponent. In the 4kids adaption, this pattern is different. She instead states the whole technique in english with Floret replacing Fleur.

Other Apendages
Aside from her arms, Robin can also replicate other parts of her body. These enable her to do a variety of things from giving her extra insight into other places with her eyes sprouting on certain objects, to transporting fallen comrades with her legs sprouting from out of their bodies.

So far the other body parts she can replicate are her eyes and legs. In the anime, it is has been shown she can replicate her ears. In an SBS Oda hinted she could replicate her breasts too.

It is unknown what other body parts she can possibly replicate aside from her arms and the ones mentioned.

Trivia

 * According to Oda, in response to a fan, if the Hana Hana no Mi was eaten by a person with hairy arms, the arms that would be sprouted would also be hairy as seen above.
 * Another SBS question asked if she could sprout breasts. Oda simply stated he was sure she could.
 * "Cien Fleur: Wing" is often viewed as a tribute to Trigun, a manga which ended in April 2007, one month before Robin used the Wing technique in One Piece. In her technique she formed an angelic appearance and carried Franky much like the scene where two of the characters, Vash and Knives, fly away in the last chapter.
