Shiku Shiku no Mi

The Shiku Shiku no Mi is a Paramecia-type Devil Fruit that allows the user to afflict others with diseases. It was eaten by Doc Q.

Etymology

 * "Shiku" is derived from Shikku, the Japanese way of pronouncing the word "sick".

Strengths and Weaknesses
The Shiku Shiku no Mi allows the user to create diseases which can hinder an opponent. The diseases can also be contagious, allowing them to spread among a group of enemies.

Intense Haki use can allow an opponent to resist and break through the Devil Fruit-afflicted illnesses, which will also result in antibodies that will cure others affected by the illness. Apart from this, the user is also susceptible to the standard Devil Fruit weaknesses.

Usage
Doc Q has used this ability to briefly turn Trafalgar Law female with the Feminization Disease (女になる病).

History
Doc Q gained his ability at some point likely as a result of the Blackbeard Pirates' Devil Fruit hunting.
