Batto Batto no Mi, Model: Vampire

The Batto Batto no Mi, Model: Vampire is a game exclusive Mythical Zoan-type Devil Fruit that gives the user the ability to turn into a vampire. It was eaten by Patrick Redfield.

Appearance
The Batto Batto no Mi is a tomato-shaped purple fruit with swirl-patterns around it, and a curly green stem resembling a tail. The fruit is small enough to be held easily 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 vampire or hybrid form. This also allows flight and the ability to suck someone's blood from their bodies either by biting their neck or digging his nails into the victim's skin. By sucking his victim's blood, he can somehow age them.

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 for him to fight.

History
Sometime after Patrick was released from Impel Down by Marshall D. Teach, he gained the Batto Batto no Mi, Model: Vampire and ate it.

Trivia

 * This is the first non-canon Devil Fruit to appear in its fruit form.
 * This is the second Zoan where the user does not turn into the animal it is named after, but rather retain his human form (as vampires are human in anatomy).
