Horu Horu no Mi is an article written by Silver-Haired Seireitou.

The Horu Horu no Mi 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, making the user a Hormone Controlling Human (ホルモン自在人間, Horumon Jizai Ningen). Horu is short for "horumon" (ホルモン), meaning hormone. In the Viz Manga and FUNimation subs, it is called the Horm-Horm Fruit. It was eaten by Turner Dionys.

Etymology[]

Strengths and Weaknesses[]

The major strength of the fruit is to create and manipulate special hormones. These hormones can manipulate various aspects of a person such as gender, body temperature, pigmentation, growth, and even emotional state. The hormones can also be used to greatly increase a person's battle capabilities through healing and energizing. By turning four of their fingers into syringes and stabbing a person, the user is able to inject these hormones and change the person on a genetic level to whatever the user desires. This process can also be used by the user on themselves to aid them. The fruit is unable to penetrate Devil Fruit users who can harden their bodies.

Other than that, the fruit seems to have no other weaknesses outside the standard Devil Fruit weakness.

It would appear that it is also possible for the user to utilize the hormones for healing purposes, including re-energizing the body after it has been severely injured. Dionys can perform other miracles on people besides himself such as extreme 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. Depending on what the conditions the patient is in, as well as the hormones used, the receiver may suffer a shortening of lifespan in exchange for a "cure".

Dionys is known to sometimes change his commanding officer and fellow Vice-Admiral, Kurama and Sparrow Ryan respectively, into women; often times done so in a mocking way to mess with them. However, it would appear that some use was found in this transformation by being used as undercover disguises. Once the need for the forms is gone, Dionys reverts both men back to their original gender.

Usage[]

Gender-Swap Victims[]

Lineage Factor Manipulation[]

Studies have shown that certain hormones are capable of significantly interfering with the function of and even altering DNA.[1][2][3] With the power of the Horu Horu no Mi, the user is capable of creating special hormones of their own design to serve almost any conceivable function permissible to the mechanism of action of actual hormones. In doing so, it becomes possible for Dionys to directly alter the Lineage Factor of his victims.

Devil Fruit Deactivation: Dionys was able to discover a method of creating a particular kind of special hormone that allows him to shut down the ability of a Devil Fruit. Anyone struck by this hormone finds themselves cut off from their Devil Fruit ability; Logia users return to their physical forms, Paramecia lose connection with the substance or material they were capable of controlling, and Zoan users can no longer exert the characteristics of their unique species. It is not that they lose their Devil Fruit power, but rather that their Lineage Factor has been signaled by the special hormone created by Dionys to deactivate the mutated gene responsible for that function. However, it is not well known that Dionys is capable of this feat. Kurama ordered him to ensure that anybody who witnessed this ability be killed to avoid its secrets from being revealed to the world. It is also for this reason that Dionys does not utilize this particular hormone technique unless the situation specifically demands it.

Logia Simulation: By manipulating his own Lineage Factor, it was possible for Dionys to simulate the characteristics of a Logia Devil Fruit. While he cannot actually imitate the power of any specific Logia, he was able to alter his genetic material to the point where his body can function like that of a generic Logia user. As such, most attacks will pass through Dionys' body without inflicting any damage, allowing his body to reform just as any actual Logia user. Of course, this also means the only sure way to land a physical blow on his body is one infused with Haki.

Behind the Scenes[]

  • Ironically, Dionys' surname of "Turner" seems to have some association with this fruit's power, given that the Horu Horu no Mi allows him to genderbend anyone and "turn" them.
