Yami Yami no Mi

Rated a Logia even though it defies the type's usual logic, this fruit lets its holder generate, command, and become darkness, making him a Darkness Human. Blackbeard acquired it by killing the fourth-division commander of the Whitebeard crew, Thatch, and taking the fruit for himself. Even among Logia it is regarded as one of a kind, and its power carries the label of being the wickedest of any Devil Fruit. Translations call it the Dark-Dark Fruit, and the fruit itself is a large, round, pale purple thing built from many teardrop-shaped lobes crowned with green leaves, so that it looks like an oversized pineapple or a cluster of swollen grapes.

The darkness works like gravity, spilling out as a black smoke that drags in and crushes anything near it, letting the user swallow matter and attacks alike or haul an opponent toward him regardless of their footing. In the manner of a black hole it pulls things into a vortex, but rather than annihilating them it seems to bank them in some interior space; Blackbeard once devoured a whole town and later spat out the wreckage battered yet not erased, with living captives surviving in shock. Its rarest trait is nullification: by touching any Devil Fruit user, Paramecia, Zoan, or Logia, he cancels their powers utterly, hitting Logia hardest since they lose their intangibility. The great price is that the same devouring darkness denies him a Logia's escape, so blows do not phase through him and in fact wound him worse than normal, and the nullification lasts only while he keeps his hand on the victim.

Teach alone holds this fruit, and he leans on it for combat above all, beating his former commander Ace despite the searing might of the Mera Mera no Mi. He favors two tactics: flooding the ground with shadow to snare and crush targets, then flinging the debris back out, and combining the pull of gravity with his power to void Devil Fruit defenses so a captured foe can be finished with a plain punch. Signature moves include Black Hole, which spreads his darkness wide to swallow and grind whatever he chooses, its follow-up Liberation, which expels the ruined remains at once, and Kurouzu, in which he thrusts out an arm to reel an enemy into striking range. Later, from Whitebeard's body, he claimed a second fruit, the quake-based Gura Gura no Mi, boasting that joining the power that reduces all to nothing with the power that shatters all made him unstoppable.
