Kura Kura no Mi (LFZ)

The Kura Kura no Mi is a -type that bestows its user the ability to mount almost anything and steer it perfectly as if it were a horse, making the user a Riding Human (騎乗人間). It was eaten by the, Dullahan.

Etymology

 * The fruit's name, Kura, comes from the word "Kura" (肉球) which means "Saddle" in Japanese.
 * In the VIZ Manga and FUNimation dub, it is called the Saddle-Saddle Fruit.

Strengths and Weaknesses
The first and foremost strength of the fruit is that the user is able to ride virtually anything as if it were a trained mount. This includes both tangible things, such as ships, brooms, animals, and even in some cases people, and intangible things such as the air itself, fire, or other elements. As proven by Dullahan, this power is extremely useful for not only travel, but battle. A second power is that by placing his “saddle” on something like a ship or other form of transportation, he gains the knowledge of how to perfectly steer it, this even includes animals.

To take this power even further, Dullahan has completely mastered his fruit, and through is capable of causing whatever he wishes to ride to take the form of a horse made from whatever they were initially formed from. In the case of intangible things such as electricity or gasses, when touched by anyone other than Dullahan, the unfortunate person in question is subjected to whatever effects the element would normally have. Unlike other Devil Fruits, doing this doesn’t seem to severely drain Dullahan any more than not turning them into horses, as it carries no more power, with Dullahan himself claiming that “It’s simply for aesthetic”.

In the case of mounting animals, while useful, Dullahan is incapable of “overriding” them, and must befriend them first. In the same vein, if he were to try to turn a person into a mount, he first needs their consent (which is rarely given and generally misinterpreted is a weird pickup line). While fully capable of riding intangible things, he’s incapable of riding products of Devil Fruits, as shown when he was attacked by Admiral Aiusagi, he was incapable of riding her resin.

Aside from these, the user suffers the standard Devil Fruit weaknesses.
