Horu Horu no Mi

The Horu Horu no Mi, also known as the Horu Horu Fruit, is a Paramecia type Devil Fruit that grants the user the ability to create and control special hormones that can affect anyone they strike by however the user desires. Horu is short for "horumon" (ホルモン, hormone). It was eaten by Emporio Ivankov.

Strengths and Weaknesses
The main power of this Devil Fruit is to create and manipulate special hormones. Ivankov can create and produce any types of hormones from his body. However, his true power lies in the distribution of these hormones from himself to his target; by hitting his targets, Ivankov can manually inject any hormones into the said target. The person receiving the hormones undergoes a genetic manipulation of their own body, which is forced to mutate by way of the injected hormones into whatever form or condition is instructed by the Devil Fruit user.

According to Ivankov, he can create hormones within his body which can change anything that he desires in his target, including gender, body temperature, pigmentation, growth or even emotional state. Typically, whenever he uses his power, he mainly changes the "gender", allowing him to either inject female hormones into a man to turn him into a woman or vice versa. However, the Horu Horu no Mi is also the source of Ivankov's "miraculous" powers, such as healing, using them to allow for a body to adjust from a fatal-condition to having a chance of survival. However, while he can make the adjustment within the body to heal from these conditions, the miracle is also dependent on the person hit by the altering hormones, whereas only those with a strong enough will can survive and use their survival instincts via the hormones to their advantage. Other than that, the user is also affected by the standard Devil Fruit weaknesses.

Usage
The named techniques that are used by Emporio Ivankov that involve the Devil Fruit are as follows:


 * Emporio Female Hormones: Through touch Ivankov apparently releases female hormones into another person's body, which can turn those it's used on into women. This was first seen being used on an inmate in Level 5.5. He has also implied that he can also turn woman into men with the opposite hormones.
 * Emporio Healing Hormones: By creating syringe-like nails on his fingers, Emporio can stab and inject hormones meant to release the body's immune system's full potential. This is the secret to his "miracle" healing. Since the hormones only unleash the immune system's potential, the chance of survival is mostly based upon the individual's will to live. This was first seen being used on Luffy to counteract Magellan's poison.
