What is diamond Devilfruit?

Diamond Devilfruit is a mythical zoan type devil fruit that allows the user to transform into a diamond human hybrid and control diamond at will. It was eaten by Jozu, one of the top commanders of the Whitebeard Pirates. The diamond devil fruit is considered one of the rarest and most powerful logia type devil fruits in the world of One Piece.

Origin of the Diamond Devilfruit

The origins of the diamond devil fruit are unknown. Like other devil fruits, it was found randomly in the world. Devil fruits are mysterious fruits found in the One Piece world that give the eater a special power, at the cost of their ability to swim.

There are different types of devil fruits – paramecia, zoan, and logia. The diamond fruit is considered a special logia type, giving the user the ability to create, control and transform into diamonds.

Logia fruits are especially rare and coveted as they allow the user to become the natural element they control. In this case, the diamond devil fruit user becomes a diamond human.

The diamond fruit is one of the powerful logia types, alongside others like the flame, ice, sand, smoke, and light fruits. This makes the diamond fruit very desirable and sought after by pirates and the navy in the One Piece world.

How Jozu Acquired the Diamond Devilfruit

Jozu was able to acquire the diamond devil fruit and become its user sometime before joining the Whitebeard Pirates. It is not known exactly how or where he found it.

The most common ways devil fruits are acquired in One Piece include:

  • Finding them randomly growing on trees/plants
  • Being gifted or sold at a high price due to their rarity
  • Stealing from another devil fruit user
  • Finding from a treasure chest/shipwreck/ancient ruin

As one of Whitebeard’s top commanders, Jozu likely went to great lengths to find and acquire the diamond fruit. With his powerful logia ability and massive strength, Jozu became a fearsome fighter for the Whitebeard Pirates, earning a bounty of over 300 million berries.

Powers and Abilities

By eating the diamond devil fruit, Jozu gained the following powers and abilities:

Diamond Body Transformation and Control

Jozu is able to transform partially or fully into diamond. He can also transform specific parts like his arms or legs. In his full diamond form, he takes on the properties of diamond becoming incredibly durable, dense and hard. Diamond is one of the hardest natural substances in the world. This makes Jozu virtually indestructible and immune to most conventional attacks while transformed.

Superhuman Strength and Endurance

In addition to his devil fruit powers, Jozu already possessed incredible physical strength and endurance. The diamond fruit enhances these natural attributes even further by combining it with diamond hardness and durability. Jozu was able to stop a two-handed vertical slash from the world’s strongest swordsman, Dracule Mihawk, with just one arm. His diamond body withstood the attack without a crack.

Diamond Generation

Jozu can generate and control nearby diamond that he touches, shaping it into weapons like giant spears or protective diamond walls. This gives him versatility in combat, allowing both offensive and defensive abilities.


Despite providing immense power, the diamond devil fruit does have some weaknesses that can be exploited in battle.

Like other devil fruit users, Jozu becomes paralyzed when submerged in water or encounters sea-prison stone. He also remains vulnerable when not transformed into diamond.

His fruit is susceptible to haki-based attacks, which can bypass his diamond defense. Stronger devil fruit abilities may also counter his diamond powers.

Notable Diamond Devilfruit Techniques

Here are some named techniques Jozu has used with his diamond powers:

Brilliant Punk

Jozu transforms his entire forearm into diamond and throws a devastating punch at his opponent.

In summary, the diamond devil fruit is an extremely powerful logia type fruit that lets the user become a diamond human hybrid. When eaten by the mighty Jozu of the Whitebeard Pirates, it granted him incredible offensive and defensive abilities to compliment his already tremendous strength. Both beautiful and nearly indestructible like a real diamond, the glistening diamond devil fruit is truly one of the most unique and formidable logia fruits in the One Piece world, driving home the name of “Diamond” Jozu.
