Komori Komori no Mi

The Komori Komori no Mi ( 小森 小森) is a Zoan-type Devil Fruit that allows its user to transform into a Peacock hybrid or full version of a Vampire Bat. Komori for “Vampire Bat”, in both Viz Manga, and the FUNimation dub, it is called the Vamp-Vamp Fruit  and was ate by Silencioso.

Strengths and Weakness
Besides the fruit giving the user immense strength, speed and many other attributes. The user's hearing go to nearly superhuman level and they can release a sonic wave to help track others and their environment. Also like the real one, the user can feed off of the blood of others. However, it seems that Silencioso feeds off of more of animals than people. Sadly the user could only feed of off this, than normal food. Other than that, the user will suffer the standard weakness of the devil fruit.
