Hana Hana no Mi

The Hana Hana no Mi, 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. Whenever the parts sprout from a chosen surface, petal-like particles also seem to originate from where they sprouted, as well as around Robin herself, further giving emphasis to the Devil Fruit's name. The fruit almost keeps its original Japanese name in the 4Kids dub by calling it the Hana-Hana Fruit, but is called the Flower-Flower Fruit in the Viz Manga and FUNimation 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
I don't think you understand yet. Power. Speed. They mean nothing to me.

The fruit's major strength, as demonstrated by Nico Robin, is the ability to sprout multiple body parts on any surface including the user's own body, 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 of being held, like being a Logia Devil Fruit user or otherwise, any opponent that faces the user is practically defenseless against them, making this fruit one of the most powerful of the Paramecia class. As she claims to Pell "speed" and "strength"" mean nothing to her, as she can render almost any foe into submission with ease. She also used her powers to create the illusion that she impaled Vivi with her arm, although she has only done this once. She can also focus her power on one or many foes around her. 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. This means that the individual strength in the replicating appendages are basically no different to that of Robin's actual corresponding limbs. So even if they sprout a 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. Fortunately, Robin can use each hand created to support each other thereby allowing her to create larger hands out of many to take on more powerful and larger foes. This aspect also makes her more versatile as it allows her to form more intricate patterns with her sprouting limbs like Cien Fleur Wing and Big Tree.

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 them as far back as when she was a child. She most notably uses the powers for combat, however she has been known to use them for other purposes. When Robin uses her power in battle, she uses a submission and grappling style where she replicates her arms on her opponent's body and puts them in painful holds to prevent them from moving.

Arms
Robin mostly uses the fruit's powers to replicate her arms in order to do a variety of 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 on 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 opponents. In the 4Kids adaption, this pattern is different. She instead states the whole technique in English with Floret replacing Fleur. In the Viz Manga and FUNimation dub, the names of her techniques are the same as the original Japanese version.

The named techniques that involve her using the Devil Fruit to replicate and sprout her arms are as follows.


 * Un Fleur (ウンフルール Un Furūru, One Flower): This attack only appeared in the anime, Rainbow Mist filler arc, she used it to push Pukau out from hiding. While 'Uno' is the typical form of the Spanish number one, and 'Un' is the french word for one, thus causing confusion among some, 'Un' is also used by Spanish speakers to mean the number one, so it is valid.


 * Dos Fleur (二輪咲き (ドスフルール) Dosu Furūru, Two Flower): Robin sprouts two arms. This number of arms being used as a named technique was first seen being used on Franky. With two arms sprouted from Franky's legs, she used Grab on his "treasure".

With her two arms sprouting from his legs, she grasped and crushed his "treasure" in a rather hilarious scene in order to change his mind.

In a response to a fan, Oda stated that Robin pretty much felt what she was touching at the time.

Other Appendages
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.

The other body parts she can replicate usually include parts of her body that enable her to do things that her arms can't do. These thus include Robin sprouting either eyes or ears to enable her to see or hear things that would otherwise be too inaccessible for her to get any closer. 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.

The named techniques that involve her using the Devil Fruit to replicate and sprout other body parts aside from arms are as follows.

Trivia
