Yomi Yomi no Mi in One Piece

The Yomi Yomi Devil fruit is a spherical golden fruit with a green stem. On its bottom, it has four stubby growths which resemble a skull. It also has swirls around it.

The major strength of the devil fruit is that it gives the user another chance at life after death. After death, the user continues to exist in whatever state they were revived in and it goes on till the user dies a second death. One drawback of this devil fruit is that its powers remain dormant until the user dies its first death and then only the power activates.

While the devil fruit allows the user to return to life, it doesn't return them to their physical body and the soul has to search for a corneal body in order to reunite with it. When the soul returns to a body, the devil fruit's power will support the user's well-being if the body is unable to support life.

The devil fruit, however, grants the user the ability to still feel pain regardless of whatever condition they have been revived under. This is what separates the Yomi Yomi devil fruit user from a Kage Kage devil fruit-made zombie. Brook can even wander around in his soul and can come back to inhabit his skeleton like an Astral projection.

Brook is in a spectral form and resembles a skeletal face and is engulfed in spiritual flames (which are not only visible but audible to people and animals). The drawback to this is that while Brook has his soul out of his body, he cannot use or move his physical body and someone has to guard his physical body so that it isn't harmed.

After the time skip, Brook can use his devil fruit to its full potential. It's revealed that in order for his soul to stay in this world, he can produce powerful energy for it to exist. He has also mastered the energy that allows his soul to reattach his bones by using his energy. He can even engulf his sword with his energy.

Even though the Yomi Yomi devil fruit's power comes into play after the user's first death, the secondary use of this fruit is basically keeping the user alive. With the help of the fruit's power, Brook is able to function without the need of his vital organs and body parts. He can also interact with the environment around him without his sensory organs. He can do all the basic body functions as a normal human.

As he is just a skeleton, the devil fruit also allows Brook to do things that most people cannot do, like living without their body tissues. He is quite lightweight and is able to execute fast attacks and also do attacks which will otherwise be harmful to others, like charging himself with electricity and becoming an electrically charged projectile. He is also able to withstand even deadly attacks to an extent. His devil fruit allows him to store objects in his skull by opening it along its crack.

Even though he can achieve a lot from his devil fruit, Brook can still feel fatigue as well as pain. He can even repair his own bones.

The techniques used by Brook are:

Kasuriuta: Fubuko Giri

In this technique, Brook combines his speed and devil fruit powers, and with the help of his sword, he creates a chilled mark that freezes the opponent’s blood. This is done with the help of the sword’s slashing technique as it contains the essence of the chilling winds of the underworld.

Hanauta Sancho: Tyamasi no Yahazu Giri

This is also a combination technique with his devil fruit in which Brook jumps into the air and uses a draw and sheathing technique to vertically slash his opponent. His speed and lightweight allow him to jump high and go far away from his enemies.

In this technique, Brook flies out of his skeleton body in soul form and then passes through his target, freezing it with his soul's coldness.
