Oshi Oshi no Mi

The Oshi Oshi no Mi is a Paramecia-type Devil Fruit that allows the user to manipulate and move the ground like clay. It was eaten by Morley.

Strengths and Weaknesses
By simply pushing the ground, the user is able to shape it according to their whims. They can manipulate many types of ground, from soft earth to hard rock to even modified stones such as bricks and streets. Thus, this fruit has a good degree of offensive power, as shown when Morley pushed an entire chunk of the street onto the Pinkbeard Pirates and overwhelmed them. The user is also capable of channeling this ability through objects they hold, and so can grab ahold of the ground by jabbing into it with a weapon.

The fruit also gives the user the ability to tunnel through the ground by pushing it to clear a way for them. Unlike conventional digging, the moved earth appears to stay in place, protecting the user from cave-ins. This tunneling ability works well for infiltration.

No weaknesses are currently known aside from the standard Devil Fruit weaknesses.

Usage
Morley often uses this fruit to move through the ground undetected, as he arrived to confront the Pinkbeard Pirates this way and infiltrated Mary Geoise by tunneling through the Red Line. His tunnels sometimes also help other Revolutionaries with infiltration, as shown when he created an underground room under Mary Geoise for his group to hide out in.

He also uses it in combat, as shown when he overwhelmed the Pinkbeard Pirates by pushing a part of the ground toward them.

Trivia

 * This fruit bears similarity to some other Devil Fruits:
 * Pica's Ishi Ishi no Mi, as they both allow the user to manipulate and reshape the ground.
 * Senor Pink's Sui Sui no Mi, as they both allow the user to move freely through the ground.
 * Inazuma's Choki Choki no Mi and Diamante's Hira Hira no Mi, as they all allow the user to manipulate the shape of matter without changing its density and weight.
