Summary

One Piece is the world's most popular comic book series of all time,^[1] only rivalled by Astérix.^[2]

It is published in Shonen Jump and is written and drawn by Eiichiro Oda.

It is an Action Adventure story about Monkey D. Luffy, a pirate who ate the Gomu Gomu no Mi, a Devil fruit that turned him into a Rubber Man. His goal is to become the Pirate King and be the man with the most freedom on the seas. He meets many people during his travels, with several of them joining his crew.

The central themes of the story are freedom versus tyranny, and bravery, joy, friendship, and compassion instead of cruelty, division, hatred, bigotry, slavery, and despair.

The extent of power within One Piece has not been fully explored as many of the Top Tiers have not been seen engaging in combat with full power, with the exception of brief confrontations (Whitebeard vs Sakazuki). However, higher tiers of the verse are shown capable of being catastrophic threats to entire Islands and Countries, or even possibly Moons. In terms of physical power, many of the stronger characters are capable of generating energy to partially destroy cities and mountains indirectly with minimal effort.

One Piece introduces Devil Fruits, which have a vast variety of capabilities. Eating a Devil fruit can make a person capable of turning their physical body into rubber, or even have the ability to control the properties of ice or fire. The only set-back seems to be the user losing the ability to swim, having their powers nullified by Sea-stone (a unique material found in a single body of water in the world), and that they would lose their life if they attempted to eat a 2nd Devil Fruit.

One Piece also introduces a power dormant within each living individual, Haki. There are two types of Haki that are universal, and can thus be discovered and developed within each living person, Kenbunshoku Haki, a power that allows users to sense the presense of others and see premonitions of the future, and Busoshoku Haki, a power that shields its user in protective armor and can harden parts of or the entirety of the user's body. There is a rare ability of Haki that only few can learn, Haoshoku Haki, which is described as being a quality of a king, and allows the user to project his will outwards, dominating the will of others in the form of an electrified aura that can knock-out or put weaker willed individuals in a seizure induced state.

There is also an introduction to a number of famous blades of high quality used by skillful swordsman. These are commonly referred to as Meito, or "ranked blades". They are used by a large amount of characters, from a common pirate, to a marine, to even one of the Yonko.

Size Calcs:

Regarding the Speed: In the case of the speed ratings for the characters, it has been decided in this thread that characters of this verse have the potential to reach FTL speeds. It has been agreed on by staff and knowledgeable members alike that Kizaru should not gatekeep the FTL speed ratings of the verse, and all FTL calculations are valid if they match the consistency of the verse.

Regarding versus match-ups: For cross-verse matchup battles, logia Devil Fruit users are susceptible to attacks that are capable of bypassing their regeneration, countering their elemental intangibility (ex: fire melting ice) or directly attacking the soul. Verse equalization does not grant an opponent from another verse the ability to utilize haki against a logia user. It was discussed here.

It has been decided in this thread that logia Devil Fruit users have the ability to automatically transform.

Regarding Combined Attacks: In the case of unified attacks, it has been decided in this thread that combined attacks done at the same time, whether with several limbs or with several relative characters, would be equal to the sum of their attack potency. An attack done by 1 person using several limbs at the same time would be equal to the sum of their attack potency. This will be taken on a case by case basis, and we should look closely to each instance of events like this to see if they truly qualify.

Regarding the canon: In terms of canon material, this wiki deems the manga as the primary canon. The anime is considered secondary canon on a case by case basis. In the case of anime, it contradicts statements, feats, personalities, and abilities of characters in many cases. This happens with censorship, filler content in canon material, and pacing. Since we have confirmation that Oda approves certain scenes in the anime, we've decided to take the anime as canon in the areas where it perfectly or similarly represents the manga, and the scenes not shown in the manga that are represented in the anime will be deemed as filler. It was decided in this thread.
