Neko Neko no Mi, Model: Leopard

The Neko Neko no Mi, Model: Leopard (ネコネコの実 モデル：豹 (レオパルド), Neko Neko no Mi Moderu: Reoparudo), also known as the Neko Neko Fruit, Model: Leopard, is a Zoan type Devil Fruit that allows a person to transform into a leopard-human hybrid and a full leopard. "Neko" means cat and the fruit is the first of the many Neko Neko Fruit models to be shown in the manga. In the Viz Manga and FUNimation dub, it is called the Cat-Cat Fruit, Model: Leopard. It was eaten by Rob Lucci.

Strengths and Weaknesses
The fruit's major strength, as demonstrated by Lucci, is that its user gains more physical strength in their hybrid and full leopard forms, equivalent to that of a real leopard and more. Their half leopard form is extremely large because it increases their original height and mass by a great degree. Fighting styles and abilities, like Rokushiki, are greatly enhanced by the power of the fruit. According to Chopper, a carnivorous Zoan like the Neko Neko no Mi, Model: Leopard is a whole lot more violent than a regular one. According to Lucci, those who have eaten fruits like it are highly specialized in physical strength and close combat.

The fruit so far doesn't seem to have any specific weaknesses outside the standard Devil Fruit weaknesses.

Usage
The powers of the fruit have been used mostly by Rob Lucci for combat purposes and to further fuel his lust for battle. Lucci notably uses the fruit's powers to make his Rokushiki techniques like Shigan and Rankyaku more powerful with the addition of claws on his fingers and the added strength in his legs respectively. Lucci, unlike other Zoan users so far, has also used the fruit's power in a more bestial manner, having used his full leopard form in battle to attack Luffy like a real leopard with claws and teeth.

While most Zoan Devil Fruits normally allow three forms of transformations under normal circumstances, Lucci is somehow able to access a fourth form, like Chopper with his Rumble Ball, only without the use of external help. Through Life Return: Kami-e Bushin, Lucci's muscles shrink and compress, granting him a smaller and slightly more human half leopard form. In this form, Lucci is apparently faster and capable of executing more hits than his normal half leopard form, he also becomes a smaller target especialy compared to his normal hybrid-form. However, in exchange for this increase of speed, his physical power apparently lowers.

Anime and Manga Differences
In the anime, the half leopard form Lucci turns to using the fruit's powers was originally colored all yellow. However on the cover of volume 44, it was shown that the form actually has some white fur underneath with some bits of his original human skin sticking out. This coloring scheme of Lucci's half leopard form was incorporated into a later episode of the anime in order to match the volume cover.
