that's about to change.

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; Nami dismissed them as mere myths until she saw the Bara Bara no Mi in action. The average person knows nothing or very little about what they are or what they do; this especially applies to people in isolated countries, even within the Grand Line, such as those of Amazon Lily and Wano Country, and even Princess Shirahoshi of Fishman Island, as none of them know about Devil Fruits, instead believing the powers bestowed to be curses or sorcery. Because of their power, if sold they can expect to fetch well over 100,000,000[2], and Devil Fruit users themselves are sold at market prices as slaves.[3] Of course, individual Fruits each have their differences in price, dependent on the powers bestowed, as the Ope Ope no Mi is worth  5,000,000,000 in the black market.[4] There are more than 100 varieties of Devil Fruit.[5]

One running theme with Devil Fruits, however, is the fact that they taste unimaginably bad, 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, which they will soon 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" or "Esper"). The Fruits come in all different shapes and colors, and all Devil Fruits presumably have swirl marks or patterns on them of some kind.[6] The only known exception is the Artificial Devil Fruit made by Vegapunk, which had ring patterns on it.[7] There can be only one of each type of Fruit at a time.[1] Only one bite is needed for the user to gain the power of the Devil Fruit, after which the Devil Fruit becomes a simple, useless, disgusting fruit. Despite this, the majority of those who have consumed a Devil Fruit have eaten the entire Fruit, as they are apparently unaware of this fact.[8] Swallowing the Fruit whole, as Buggy did, has the same effect.[9] Peeling off the skin and eating it piece by piece, such as Kaku and Kalifa did, also works. After ingesting the Fruit, the powers within affect the eater's Lineage Factor.[10]

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 two Yonko, Marshall D. Teach and Charlotte Linlin. They are common in the Grand Line compared to the other four blues. A typical Grand Line Pirate crew will often center around a captain with a Devil Fruit ability (such as the Bellamy Pirates, the Wapol Pirates, or the Foxy Pirates), while stronger crews and organizations will often contain many Devil Fruit users (such as the Whitebeard Pirates, the Donquixote Pirates, Baroque Works, or the Marines). Two of the Yonko (Blackbeard and Kaido) even take this so far as to go out of their way to gather as many Devil Fruits as possible using their own unique methods. In fact, since entering the Grand Line, nearly every single major opponent that Luffy has faced had a Devil Fruit ability, while in the East Blue he only faced two (not including Alvida, who ate her Devil Fruit later after their encounter).

Like many series, One Piece follows the trope that a Devil Fruit power also generally affects the clothes that the user is wearing. Paramecia Fruit users alter their clothes along with themselves automatically (for example, Luffy's shirt will never burst a button when his chest is swollen in Gear Third, Mr. 1's pants become blades along with his legs, etc.), Zoan Fruit users' clothes will fit in the same proportions after their transformation (Chopper's hat grew big when he was in Monster Point, Jabra's shoes are considerably stretched when in the hybrid form), and Logia Fruit users transform their clothes (and subsequent accessories) to their element along with themselves. Oda explained in a SBS once that if he had done it realistically, the manga would have too much unnecessary nudity.[11] However, some users do not seem to adhere to this, such as Jewelry Bonney and Honey Queen, whose clothes do not change proportionally to their powers.

It is implied that this common trait can also be extended drastically, after Devil Fruit powers have been "awakened," where the powers would not only affect a user's clothes but also their surroundings, as demonstrated first by Doflamingo when the Ito Ito no Mi affected everything around him.[12]

Some Devil Fruits may also lead to the user being considered a "freak". This is due to some of the abilities considered far too strange or frightening for normal people to accept.[13] In many cases, Devil Fruit users are considered a different race altogether, and with good reason. Since each Devil Fruit user possess a unique ability, they each require different countermeasures to deal with them, outside of their standard weakness to submersion, seastones and Haki. As such, once an unfamiliar Devil Fruit user is identified on the battlefield, the standard approach is to take a step back and experiment different means of attacks on the opponent.

Devil Fruit powers are so varied and mysterious, that the powers gained from eating one can serve purposes that may transcend normal limits. Such surprising effects that Donquixote Doflamingo believes he may find one to save Trafalgar Law from the reputably incurable Amber Lead Syndrome, showing that he places more faith in a Devil Fruit of such power than in medical science that failed to find a cure.
