Yami Yami no Mi

The Yami Yami no Mi, also known as the Yami Yami Fruit, is Logia type Devil Fruit that allows the user to become "darkness". Yami (闇) is the Japanese word for "darkness." It originally belonged to Commander Thatch of Whitebeard's 4th division, but was stolen and eaten by Marshall D. Teach.

Appearance
The Yami Yami no Mi is a purple pineapple shaped fruit with swirls on it.

Strengths and Weaknesses
According to Blackbeard, this fruit is "unique", even for a Logia type. It allows the user to transform into and control darkness and gravity. The user can absorb physical matter and attacks of any type, either by sucking it into a dark mist which spreads from the user, or into the user's body itself. The user can use this ability to irresistibly draw the opponent to them. The most unique and powerful strength the fruit has is that the user also has the unique ability to nullify the powers of other devil fruit users by simply touching them and "sucking" their abilities out. All powers from other Devil Fruit types from Paramecia, Logia, and Zoan are affected by this.

The major weakness of this particular fruit, however, is that the darkness the user transforms into swallows up everything, including attacks. So unlike most Logia users, the user of the fruit is still vulnerable to attacks as they cannot turn into darkness in order to dodge them. If they fail to absorb the enemy's attack in time, the user can be hurt like any other normal human being or even more, as stated by Teach. In addition, while the ability to nullify devil fruit abilities is powerful, the user must actually touch and remain in contact with the victim for the affects to remain constant, meaning that if the victim separates from Blackbeard, they quickly regain their devil fruit ability. Other than that, the user is also affected by the standard Devil Fruit weaknesses.

Usage
The fruit's bestowed powers, as used by Teach, have been used so far for mostly combat purposes. He is able to fight on par with Ace, his former commander, despite Ace possessing the Mera Mera no Mi. Teach is also able to use the fruit's powers to heal his wounds to a point by sucking in the projectiles and attacks that have penetrated his body. With this frightening power of darkness, Teach plans to become the next Pirate King and conquer the world. The named techniques that are used by Teach that involve the Devil Fruit are as follows:


 * Black Hole: Blackbeard spreads his darkness over a large area and swallows up anything he chooses, such as an entire village on the island of Banaro. This was first seen being demonstrated before Ace.


 * Liberation: Used following Black Hole. Blackbeard expels all of the destroyed remains of what his darkness has swallowed up at once. This is especially good at demonstrating his power. This was first seen being demonstrated before Ace.


 * Kurozu (Dark Vortex): Extending one arm towards his opponent, Blackbeard activates the gravity power of his darkness to pull them into his grasp. Blackbeard can then attack them with his massive strength. This move is particularly useful in conjunction with the Yami Yami No Mi's power-cancelling abilities, since the target could easily avoid it by fighting at a distance from Blackbeard, as Ace attempted. The name of the attack is also a pun on the english word "close". This was first seen being used on Ace in order to grab him.
