Karori Karori no Mi

Introduction
The Calorie Calorie Fruit is a Paramecia class Devil Fruit; eaten by the as of yet unnamed Cook and Division Commander for The Collosal Pirates. The fruit has been shown to grant the user an insane amount of superhuman strength, speed and durability by simply exchanging his excess weight into power. Naturally, this is perhaps one of the reasons, if not the DEFINING reason, why he became a Division Commander.

Usage
The most common seen power used by the Calorie Calorie Fruit's user is the ability to shave off extra, unnecessary pounds of weight in order to grow stronger whenever he feels like it. This also applies to his speed, stamina, and defensive capabilities as well. Thus allowing the user to attain immense levels of power without much effort; though possibly because of over-specialization or abuse of his powers, the user hasn't shown any additional abilities beyond this point.

Strengths
The greatest strength this Devil Fruit provides is the instant achievement of superhuman strength, speed, and endurance by simply removing unnecessary calories from the user's body. Thus allowing the user to perform amazing feats of physical strength and speed that are on par with any Fishman, Bigfoot, or other superhuman species found within the One Piece world. Capable of destroying multi-story buildings with simple punches, kicks, headbutts, or any other form of attack; as well as being able to run at disturbingly high levels of speed and withstand attacks that should normally kill him, the user can fight evenly with almost any strong opponent he wishes, without having to spend tireless years of training or practice.

Another, lesser known benefit, is the ability to remove the effects of poor eating habits from the user's system, by reducing the fat and calories they've built up over time. This allows for a win-win situation, where the user can perform their superhuman abilities, without being hampered by their previous poor health. And when the user feels sick from his bad health, he can simply remove all of his additional weight; by simply trimming down to his preferred size.

Weaknesses
The user suffers from standard Devil Fruit weaknesses. Another major weakness is the inability to do much more with the Calorie Calorie Fruit's powers; as the Devil Fruit is too specialized to support any other functions aside from granting its user boosts in the physical department. Additionally, the user is unable to transfer their Devil Fruit's strength granting properties to others, or other objects in the same fashion as Haki; thus limiting the user's abilities to simple berserker attacks and assaults.

Trivia
