Zou Zou no Mi

The Zou Zou no Mi is a Zoan type Devil Fruit that allows user to become a large elephant at will. "Zou" means "elephant" in Japanese. In the Viz Manga, it is called the Elephant-Elephant Fruit. It was "eaten" by Spandam's sword, Funkfreed, through the process developed by Vegapunk.

Strengths and Weaknesses
The most basic strength of the fruit is that it gives its user the strengths of an elephant. In the case of Spandam's sword, the fruit's most major strength is that it has given life to an otherwise inanimate object. With this, Spandam has been given a unique weapon with which to fight with.

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

The animal created from this fruit, however, has somewhat of a minor weakness with it though, considering the circumstances around it. While the fruit has given Spandam's sword the strength and intelligence of an elephant, the fruit inadvertently also in a sense gave the sword some common sense in the matters of pain and death. This was best seen when Franky threatened to shoot Funkfreed in the face. While the sword may not have been alive to begin with, it was afraid of being killed by Franky like a real elephant would be in such a situation. In other words, the fear of being killed was instilled into the sword thanks to the power of the fruit.

Anime and Manga Differences
In the anime, the elephant form that Funkfreed transforms to using the Devil Fruit's powers is colored white. However, on the cover of volume 42, it is shown that the elephant form is naturally gray colored. This difference in color between manga and anime is partly due to the common fact that the intended colors came out much later after the anime. This is also due to the fact that Funkfreed's elephant form resembles greatly a stereotypical white elephant, commonly revered in India, in the uncolored pages of the manga.

Attacks

 * Ivory Dart (象牙突進(アイボリーダート)): A non-lethal move intended to disable Nico Robin. Funkfreed extends his body rapidly (stretching in a manner not unlike to a Gomu Gomu no Mi user) to deliver a powerful headbutt, catching Robin between his trunk and tusks. Another possibility of this move is if his trunk is a sword, then the move could trap and slice the target.
 * Elephant Chop (エレファントチョップ): Spandam swings the sword over his head, and Funkfreed morphs into his elephant-sword hybrid form, and rushes forward to spear an opponent with his sword-trunk.
