Yami Yami No Mi

Name: Yami Yami No Mi

Type: Logia

Discription: The first and foremost strength, as demonstrated by Blackbeard, is that it allows the user to control darkness and its unique property of gravity. The darkness is visually demonstrated by a black smoke-like fluid substance spreading out of the users body. The darkness is a void that devours everything and crushes them. Due to this, the user can absorb physical matter and attacks of any type by sucking it into the darkness. The user can also use this ability to irresistibly pull the opponent to them, regardless in what state they're in.

The most unique and powerful advantage of the fruit, is that the user also has the ability to nullify the powers of other Devil Fruit users by simply touching them and draining them of their abilities. All powers from other Devil Fruit types, be it Paramecia, Zoan, and Logia, are affected by this, though Logias are most affected as they can no longer transform into their respective element.

Similar to a black hole, the user can absorb things inside a vortex. Although it seems that it does not completely compress and annihilate that what is sucked as a black hole would do, rather it seems to be some form of space where things are stored. Blackbeard sucked an entire city to it, and eventually regurgitated everything back out reduced to scraps. The guards of Impel Down that Blackbeard sucked in survived, although they were heavily wounded and in shock.

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 the attacks cannot pass through the darkness they turn into. 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 effects to remain constant, meaning that if the victim separates from the user's physical touch, they quickly regain their Devil Fruit ability. Though this is the case for Devil Fruit users in most cases, this power however can be overcome in certain situations.

Other than that, the user is also affected by the standard Devil Fruit weaknesses.
