Falling outside the manga's canon and belonging to the Paramecia class, this fruit lets whoever eats it borrow the look of people who have died, a trait that names its holder an Onibi Human. Kardia is the character who consumed it. The title most plausibly springs from onibi, which in Japanese folklore are the spirits said to rise off the corpses of humans and beasts alike.
What the power really commands are will-o'-the-wisps, flame-shaped spirits that carry out its effects. Should one of those wisps brush against a keepsake belonging to someone deceased, it can drape the user in that individual's form and skills. The very same ghostly flames double as tools of attack when a fight breaks out. Past that, the holder stays subject to every ordinary Devil Fruit drawback.
Kardia alone has held this fruit. He aimed it at the Straw Hats by borrowing two familiar faces: taking Ace's shape to mislead Luffy, and Donquixote Rosinante's to trick Trafalgar Law. In each case the disguise was meant to knock the target off guard and open the way to defeating them.
The Nibi Nibi no Mi is a non-canon Paramecia-type Devil Fruit that lets its user take on the appearance and abilities of deceased people. Eating it makes the user an Onibi Human, and it was introduced in the One Piece Premier Show 2021.
Kardia is the only known user of the Nibi Nibi no Mi. He used its power to impersonate dead characters in order to deceive his opponents.
The Nibi Nibi no Mi channels will-o'-the-wisps, flame-shaped spirits that can drape the user in the form and skills of a deceased person if the wisp touches a keepsake belonging to that person. The same ghostly flames can also be used offensively in combat.
Kardia used the Nibi Nibi no Mi to take on Portgas D. Ace's shape to mislead Luffy, and later Donquixote Rosinante's shape to trick Trafalgar Law, hoping to catch each target off guard.
The name Nibi Nibi no Mi most likely comes from onibi, spirits from Japanese folklore said to rise from the corpses of humans and animals.
