1 Yami Yami no Mi
Out of all the Devil Fruits to exist in One Piece, the Yami Yami no Mi is known to be the most sinister of all. This Devil Fruit is the counter to all Devil Fruits in One Piece and that is simply down to the fact that it stops other Devil Fruit users from utilizing their abilities as long as Blackbeard is in contact with them. The Yami Yami no Mi is a logia type of Devil Fruit, however, it doesn't offer the intangibility of a Logia. It also makes sure that Blackbeard takes more damage than an average user as this fruit sucks in everything.
However, in return, it offers the power of infinite gravity and darkness, which allows Blackbeard to suck in everything, including the powers of other Devil Fruits. In its Awakened state, this fruit is likely going to be able to nullify Devil Fruit powers without even making direct contact and that is what would make it truly the most overpowered Devil Fruit in the world of One Piece.
