Horo Horo no Mi

The Horo Horo no Mi, also known as the Horo Horo Fruit, is a Paramecia-type Devil Fruit that allows the user to produce Negative Ghosts. "Horo" means ghost in Japanese. It was eaten by Perona.

Strengths and Weaknesses
The major strength of the fruit, as demonstrated by Perona, is that it gives it's user the ability of to produce spectral replicas that they can control. The user can also seperate into the ghosts and reform. Should a person be passed through by one of these, they immediately fall on their knees in manner similar to Foxy and become very negative about themselves. These replicas can also be used to gather information from different areas.

Though the power of these ghosts are seemingly unavoidable, they have no affect on a person who is orignally pessimistic about himself. This is clearly seen when several of Perona's Negative Ghosts passed through Usopp. Usopp, being pessimistic about his own abilities, was completely unaffected by them.

Other than that, the user is also susceptible to standard Devil Fruit weaknesses.

Usage
The fruit's bestowed powers, as used by Perona, have been used for both combat and information gathering situations. She has used her Negative Ghosts to weaken enemies so that her allies, like Absalom's Zombie Soldiers, can have an upper advantage. She has also used her ghosts in an elaborate information gathering system, called "Ghost Network", in order to monitor things around and on Thriller Bark.
