Devil Fruit (悪魔の実 Akuma no Mi) is a mystical fruit found in the world that can give the eater many different and varying kinds of strange and interesting abilities depending on the type and variation of the fruit itself. There are some seen only in the anime and different ones seen only in the manga. However, most of them appear in both and are crucial in the storyline where many main characters possess their powers.
Devil Fruits are said to be the fruits of the Sea Devil and that the secret to their power is hidden in the Grand Line. Because encounters with them are rare (especially outside the Grand Line), a number of rumors about them have risen, making it difficult to tell whether some things are fact or fiction. The average person knows nothing or very little about what they are or what they do. Because of their power, if sold they can expect to reach well over 100,000,000 and Devil Fruit users themselves are sold at market prices as slaves. There are more than 100 types of Devil Fruit.
One running theme with Devil Fruits, however, is the fact that they taste unimaginably horrible, to the point of making it seem like the user had taken poison. The Devil Fruit, when consumed, gives the consumer a power or special trait, though they will not immediately become aware of; a person who has eaten a Devil Fruit and gained its powers is known as a Devil Fruit User (能力者 Nōryoku-sha, literally meaning "Ability User"). They come in different shapes and colors, and all Devil Fruits have swirl marks or patterns, presumably, on them of some kind. There can be only one of each type of fruit at a time. Only one bite is needed for the user to gain the power of a Devil Fruit, after which the Devil Fruit becomes a simple, useless, disgusting fruit. Swallowing the fruit whole, as Buggy did, has the same effect, as well as peeling off the skin and eating it piece by piece also works. After ingesting the fruit, the powers within affect the eater's lineage factor.
Devil Fruits are the origins of the powers of some of the strongest people in the current generation of the world, including rookie pirate crews, Marine admirals, Shichibukai, and at least one Yonko. There is no way to tell how Devil Fruit powers will fare when pitted against one other. A Devil Fruit user who normally dominates all other powers can sometimes be brought down by a power considered "weak" in comparison. A Devil Fruit power also generally affects the clothes the user is wearing. Paramecia fruit users alter their clothes along with themselves automatically, Zoan fruit users' clothes will fit in the same proportions after transformation, and Logia fruit users transform their clothes (and subsequent accessories) to their element along with themselves.
The same power of a Devil Fruit can exist more than once, though no two Devil Fruits of the same kind may exist at once. Though the process of the Devil Fruit reappearing in the world is unknown, several Devil Fruits have seen their consumers either die or met unknown fates within in the storyline. There is a book in the Grand Line with Devil Fruits listed (although sometimes a Devil Fruit is said to have been unidentified.
When a Devil Fruit user dies, their ability is reborn into another fruit of the same kind. Instead of growing from a plant, the ability simply regenerates inside the closest appropriate fruit. Another characteristic of a Devil Fruit's growth is that the stem becomes noticably curlier than it was when the fruit was not endowed with the ability.
Side Effects of Devil FruitsEdit
With this new power comes a weakness: the sea rejects the new Devil Fruit user and they become helpless while submerged in water; the Devil Fruit users are susceptible to all types of water, not just seawater. This includes the white sea surrounding Skypiea. He elaborated on this, saying that "moving" water, like rain or waves, does not weaken Devil Fruit users, while standing water does.
It is not until a Devil Fruit user is knee deep in water that they become immobilized. Being in contact with the sea does not instantly rob their strength unless it reaches a certain level. Even if a part of the user is submerged, they can not use their Devil Fruit powers, no matter how much or how little is submerged. However, if the user's body has been permanently altered by the fruit, then the user's ability can be manipulated by outside sources. Being weak against the sea proves deadly to many Devil Fruit users who are pirates and Marines sailing the Grand Line. As well as this, the use of a Devil Fruit puts users at odds with races like the fishmen and some with greater weakness to the sea than normal are almost useless against these races. However, the Devil Fruit power will also render a Fishman or Merman just as weak in water as anyone else, so this advantage is only applied to one that has not consumed a devil fruit themselves.
Kairoseki, a special substance that emits the same energies of the sea, can also cancel out Devil Fruit powers through physical contact with the user. Depending on how much physical contact the users have with the Seastone, the more their movement is weakened. One rumor is that Devil Fruits house actual devils that will fight when placed in proximity of one another. The resulting battle would destroy the users' bodies. Nevertheless, Blueno contradicted this claim, stating that Grand Line scientists have noted that the phenomenon of one's body destroying itself only occurs when one consumes two Devil Fruits.
Consequences of ConsumptionEdit
The main attraction to eating a Devil Fruit is the powers bestowed upon the user with many spending their entire lives seeking out just one type of fruit. More often than not, the power is far more useful than never being able to swim again. However, due to lack of information known by most, and with Devil Fruits still unknown, the average consumer plays Russian Roulette consuming one and there is no way of changing what power you get once consumed. With no way of removing the curse, all Devil Fruits users are labeled as "freaks", "Devils", and "monsters" for the remainder of their lives. All Devil Fruit users have to be trained to a certain degree from simple activation control to full battle techniques.
Another problem with the Devil Fruits is that a few of them offer "weird" or "useless" powers. While many citizens can be fascinated by their powers, others may leave a consumer leading a miserable life full of discrimination from those around them. However, due to the lack of information within some societies and cultures, misconceptions on how this power was achieved can lead to manipulation of individuals for that users own purposes.
Artificial Devil FruitsEdit
Dr. Vegapunk, a Marine scientist, is responsible for the research into the effects of Devil Fruit and kairoseki heavily. His research has also led him to devise the method that lets an inanimate object (such as a gun or a sword) gain the effect of a Devil Fruit (it has not yet been shown how this is done and this has been only done with Zoan types that transform the weapon into an animal). He also managed to replicate the effects of one fruit to a certain level, and has even created a synthesized Devil Fruit, though it was said to be imperfect. Caesar Clown stated that he has done numerous experiments on his own Devil Fruit, insinuating that he managed to enhance its power after consumption. He has not yet explained what his research was or how he did it though. He also managed to create his own version of artificial Devil Fruits whereas Vegapunk failed; these are restricted to Zoan class, named Smile.
Types of Devil FruitEdit
Paramecia (超人系 (パラミシア) Paramishia, literally translated as Superhuman System) is the most common of the three classes, users of Paramecia class Devil Fruits gain superhuman physical abilities or powers, such as shock wave generation and locking onto targets. Other users can alter features of their bodies or their environment, such as a body of blades and levitating objects. Finally, there are some users that can manipulate and generate some kinds of substances, such as wax and poison.
Zoan (動物系 (ゾオン) Zōn, literally translated as Animal System): The users of Zoan class Devil Fruits gain the ability to transform into an animal (and acquire every ability affiliated with said animal). The user can also transform into a human-beast hybrid form. There are Zoan Devil Fruits not only for common animals, but for prehistoric or ancient animals and mythological creatures as well (ancient and mythological are rarer, with mythological said to be even rarer than some Logia Devil Fruits). There also exist manufactured Zoan Devil Fruits.
Logia (自然系 (ロギア) Rogia, literally translated as Nature System): The rarest of the three classes, users of Logia class Devil Fruits gain the ability to transform themselves into an element (making them intangible or indestructible, the exception being the darkness Logia power which keeps the human body and makes the user more vulnerable towards pain). They also gain every ability related to that element and gain the skill to disperse, control and rejoin any part of their bodies while conscious and in control of their powers (including explosions, bullet wounds or cuts). Logia users can move every part of their transformed bodies while in element form.
