Batto Batto no Mi, Model: Vampire

The Batto Batto no Mi is an game exclusive Zoan-type Devil Fruit that gives the user the ability to turn into a bat. It was eaten by Patrick Redfield.

Appearance
The Batto Batto no Mi is a melon-shaped purple fruit with swirl-patterns around; it has a green stem which arcs and curls at the tip, making it resemble a tail. The fruit's size is big enough to be held in a man's hand.

Strengths and Weaknesses
The main strength of the fruit's power is that it allows the user to transform into a full bat or hybrid form. This also allows flight and the ability to suck someone's blood from their bodies.

The fruit so far does not seem to have any specific weaknesses outside the standard Devil Fruit weaknesses.

Usage
Redfield is seen flying with his wings and attempting to suck the blood of Yadoya. He later sucks Luffy's blood, leaving him in a state similar to aging him by many years. Luffy is left with white hair and gray skin, and his "aged" body makes it difficult to fight.
