Batto Batto no Mi, Model: Vampire

The Batto Batto no Mi, Model: Vampire is a Mythical Zoan-type Devil Fruit which allows the user to transform into a Vampire hybrid or full Vampire at will. It was eaten by Azrael

Strength and Weakness
The Batto Batto no Mi: Moderu Banpaia gives the user increased physical capabilities and the ability to transform into a hybrid or complete vampire. The exponential boost in physical ability allows the user to perform extraordinary feats of strength and speed. As well as providing an equal enhancement in durability and maneuverability. The fruit is one of the Mythical Zoan fruits that provide flight through giant bat-like wings as well as access to incredibly sharp claws and a powerful tail.

It is a fruit that is extremely similar to Paramecia Devil Fruit by providing a supernatural ability to the user. The user is able to absorb the life-force through the blood of the living and freshly dead. Actively causing them to rapidly age during the duration of absorption. The accumulated life-force is then used by the user to heal as well as retain their youthfulness. Thus causing the Bat-Bat Fruit, Model: Vampire to classify as one of the fruits that grant the user immortality. However, the user is able to weaponize the absorption of life-force and rapid aging of the target while healing themselves. Absorbing life-force is done through contact with blood, requiring the user to wound the target through the usage of their natural weaponry. Common usages surround biting and impaling.

Other than the aforementioned weaknesses, Azrael is also affected by the standard Devil Fruit weaknesses

Usage
Azrael is shown to possess great control of his transformations. Isolating the form to selective parts of his body in order to absorb his target's life-force without transforming fully. He is also fond of growing his Full-Beast form wings in his human state for better maneuverability.
