Kyubu Kyubu no Mi

The Kyubu Kyubu no Mi is a Devil Fruit eaten by Gairam. It allows the user to cut anything they touch into cubes, making the user a Cube Human (キューブ人間). Kyubu comes from Kyūbu (キューブ), the Japanese way of pronouncing the word "cube".

Strengths and Weaknesses
The main strength of this fruit allows the user to make anything into a cube and stack them. The user is also able to levitate the cubes and form structures from them such as towers and mazes or use one as a floating platform. The user can even compress the air around them into a cube. He is also able to turn living creatures, such as humans, into cubes.

This fruit doesn't have any specific weaknesses outside of the standard Devil Fruit weaknesses.

Usage
Gairam primarily uses this fruit's power for combat. He is also able to channel the fruit's power through his hammer to turn whatever he strikes with it into cubes.
 * Cube Break (キューブブレーク): Gairam puts his hand on a structure and breaks it down into cubes. He first used this on a Marine battleship.
 * Cube Booster (キューブブースター): Gairam sends the cubes he creates flying at his opponent in order to crush them. This is first used against Luffy.
 * Air Cube (エアキューブ): Gairam uses the air itself to create a cube of compressed air in his hands.
 * Air Cube Booster (エアキューブブースター):: Gairam launches his Air Cube at his opponent where it explodes like a bomb. This was first used against the Buggy Pirates, but was stopped by Galdino's Candle Wall.


 * Totem Cube (トーテムキューブ): After transforming his opponent into a cube, Gairam stacks several cubes on top of each other with them on top and knocks away the bottom cube to torment them. This was first used against Buggy.

Trivia

 * Gairam's Air Cube Booster is similar in principle to Kuma's Ursus Shock, only much less destructive.
