Seru Seru no Mi

The Seru Seru no Mi (細細の実) is a Paramecia type Devil Fruit, in which the user is able to produce and manipulate special cells. Seru is the Japanese word meaning "Cell", in both Viz Manga, and the FUNimation dub, it is called the Cell-Cell Fruit and it eaten by ___.

Strengths
The fruit's powers originally were revealed by Dr. Slugger who had went into great research for this fruit, from the data that he had gathered. He had revealed that the user of this fruit is able to create countless micro-cell like beings, in which he or she is able to manipulate fully. This can range from having the cells acting like anti-bodies and white blood cells within the body. They also have the power to go into others and thus manipulating them from in their Slugger went on and saying that through several experiments he had done with the owner of the fruit, is that the user himself is able to go so far as having the cells go into the D.N.A strands and collect pieces of D.N.A for him or her. By this the user can "rewrite", the D.N.A of another or even himself, such examples were. That the user had taken a piece of dog D.N.A and added it into his own D.N.A strand, this allowing the user to have a great increase sense of smell to that of a dog. However there hasn't been anymore talk or research into the devil fruit's fullest abilities.

Weakness
The cells the user creates seem to be high susceptible to the elements so as such, the cells seem to need to be under certain situations. Slugger, discussed that he feels that the human body temperature seems to be the best place for these cells to be used in. The extreme heat or cold will simply kill these cells, need water itself has shown to have killed off these cells as well, such as the rain and snow. Other than this, the user will suffer the standard weakness of the devil fruit.
