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. "Batto" is the Japanese pronounciation for bat. It was eaten by Patrick Redfield.

Appearance
The Batto Batto no Mi is a purple tomato-shaped 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, the ability to create a shroud to cloak himself, and the ability to suck someone's youth from their bodies either by biting their neck or digging his nails into the victim's skin. By sucking his victim's youth, he can age them and regain his own youth. The user also shows an apparent form of teleportation by appearing and disappearing in blood-red bursts of energy.

It seems that to access the fruits powers, the user must continually absorb the youth of others, as shown when Redfield gave it back to Luffy and Yadoya, he stopped using it. There were no ill effects to the victims after their youth was returned. Otherwise, it has standard Devil Fruit weaknesses. It may appear that this fruit shares the same weaknesses of a traditional vampire like weakness to sunlight although it was shown that he was using an umbrella in the cutscene.

Usage
Redfield is seen flying with his wings and attempting to suck Yadoya's youth. He later sucks Luffy's youth, 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. He uses the wings and claws to swipe and or cut his opponent.

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.
 * Despite being a vampire, the user does not suck or drain blood from their victims, instead, they drain their youth.
