Kopi Kopi no Mi

The Kopi Kopi no Mi is a non-canon Paramecia-type Devil Fruit that allows the user to copy other people's abilities with an unknown method. It was eaten by Chameleone.

Strengths and Weaknesses
The main power of this fruit is to copy other people's abilities and appearances through touching and taking a damage from an attack by the one he needs to copy.

It seems that the user needs to be damaged by the attack from the person he needs to copy thus giving it a big weakness. The user also needs a great concentration in using this ability as seen when Chameleone changes back to his original self whenever he sneezes. Otherwise, the user is effected by the standard Devil Fruit weaknesses.

Usage
Chameleone uses his power to disguise himself as somebody else and uses their power for his own sake. Some of the Devil Fruit users he can copy are Luffy, Smoker, Ace and Kizaru.

Trivia

 * This fruit is similar to Mane Mane no Mi, as both can copy or imitate something from someone else.
