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." This Devil Fruit is apparently a pineapple shaped fruit with swirls on it. It originally belonged to Commander Sachi of Whitebeard's 4th division, but was stolen and eaten by Marshall D. Teach.

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 and redirect it back at others, either by sucking it into a dark mist which spreads from the user, or into the users body itself. The user can make gravitational pulls, which draws the opponent to him/her. The user also has the unique ability to nullify the powers of other devil fruit users by simply touching them, by "sucking" their abilities. The darkness the user transforms into swallows up everything, including attacks, so unlike most Logia users, the user of this fruit is still vulnerable to attacks which causes more harm than they normaly would.

Attacks

 * 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 Varona.
 * 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.


 * 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.
