Kyuuketsuki Kyuuketsuki no Mi (Vampire Vampire Fruit) is a Mythical Zoan that allows the user to turn into a Vampire.
Users possess the traits, attributes, characteristics and/or abilities of vampire, a being who subsists by feeding on the life essence of living creatures (often in the form of blood), regardless of whether the vampire is undead or a living person/being. They achieve this either through full or partial transformation into vampires, choosing to mimic certain aspects of vampiric beings, or simply already being a vampire in the first place. While all vampires need some form of life-essence, the quality and quantity vary greatly: from daily to rarely, from needing lethal amounts to barely notable, from sentient blood freshly drained to rare steak.
