The Gum Gum Devil Fruit, a hidden treasure of the sea, first appeared in the opening chapter of the One Piece series. The Red Hair Pirates brought it with them in a treasure chest to Foosha Village.
The Gum-Gum Fruit, also known as the Gomu Gomu no Mi, is a Paramecia-type Devil Fruit that the protagonist of One Piece, Monkey D. Luffy, ate at a very young age. This fruit has permanently turned his body into rubber and has thus given him the ability to stretch.
The fruit was a treasure sought by the World Government for over 800 years, until it was stolen by Shanks and his crew in recent history. It was then accidentally eaten twelve years ago by the series' protagonist, Monkey D. Luffy.
Luffy's rubber attributes are a result of him eating a devil fruit called the Gum-Gum Fruit Granting him a rubber-like body, his powers make him immune to electric attacks and most blunt forces, but he is susceptible to attacks made with a sharp object or weapon (eg. sword, spear).
The real name of Luffy's devil fruit is Hito Hito no Mi, Model: Nika. Luffy awakened his powers during his fight with Kaido and transformed into a mythical being called Nika, the Sun God. This form is also called Gear 5.
Over the years, he has come a long way and become one of the strongest pirates on the seas. Zoro has attained terrific strength, but he does not rely on a Devil Fruit at all.
Logia are considered to be the rarest, while Paramecia are the most common. Zoan are somewhere in between in terms of rarity. Certain Zoan are extremely rare because of their mythical or prehistoric natures, and a number of Paramecia are rare because of their abilities and because of how frequently they appear.
However, physical blows without Haki don't work on him due to his rubber body, and the only slashing-style ninjutsu Sakura is shown to know is a scalpel-like blade. With that being her only weapon to hurt Luffy with, it's likely she will lose this fight in embarrassing fashion.
In the Post-War arc, one of the Five Elders stated that "D." means danger. After the timeskip, Law mentioned the Will of D. once more when Doflamingo asked him why he had so much faith in Luffy. After visiting Laugh Tale, Kozuki Oden mentioned that he and the Roger Pirates had learned the meaning of the D. name.
One Piece fans know that the protagonist, Monkey D. Luffy, has spent his entire life at sea and yet, he cannot swim. This is because Luffy ate a Devil Fruit, a magical fruit that grants its eater extraordinary abilities but also takes away their ability to swim.
Despite its initial impression, Luffy's Devil Fruit is also a Zoan-type of the Mythical branch, the Hito Hito no Mi, Model: Nika. Luffy's appearance and abilities in awakened form (which he calls Gear Fifth), however, differ greatly from other awakened Zoans shown recently in the series.
Mihawk's strength is so great that Don Krieg accuses him of having the power of a Devil Fruit. While it has not yet been officially confirmed that he does not, it has only been indicated that his abilities are from pure skill and power.
As mentioned above, there are four gods in One Piece namely the Sun God, Rain God, Forest God, and Earth God. Although it was revealed that Luffy's Devil Fruit gave him the powers of the Sun God Nika, the identities of other characters with godlike powers are still a mystery.
Mortician: Sasuke was also way faster, Zoro was fast enough to keep with the teleporting Former King of Sorbet Bartholomew Kuma.
Unfortunately, Luffy's rubber body doesn't make him impervious to fire, so Sasuke is already stronger thanks to his Amaterasu, and his Susanoo's arrows are strong enough to pierce Luffy's body.
Zoro can eat 3 devil fruits.
Can Luffy take second devil fruits or not? No. At present the only person who has, somehow, managed to acquire two devils fruit powers is Blackbeard, and no one knows how he did that. Normally if someone eats a second devils fruit, it'll poison them and they'll die.
The Inu Inu no Mi, Model: Okuchi no Makami is a powerful Mythical Zoan type of Devil Fruit that was introduced to the fans towards the end of the Wano Country arc. This legendary devil fruit is precious and was in possession of Kaido of the Four Emperors for quite a long time.
In the 98th volume of One Piece, Oda answered a fan question about what Devil Fruits would fit Nami, Zoro, Sanji, Usopp, and Franky best. Nami's Fruit is the Rumble Rumble Fruit, which lets its user wield the power of lightning.
In the two-year time skip, Zoro trained under Dracule Mihawk, popularly known as Hawk Eyes Mihawk. One of the popular theories is that the scar on Zoro's left eye is a training mishap. Many believe that Zoro lost his left eye during his training in some sort of accident or battle.
Hito Hito no Mi, or human human fruit, is a zoan type devil fruit. This fruit's effects on humans are unnoticeable because the effect itself is turning the user into a human. If Sanji ate this fruit, the only ability he would gain is a swimming disability.
