Oni Oni no Mi, Model: Stone Ogre

Introduction
The Hayaku-Hayaku' no Mi is a Paramecia-class Devil Fruit that allows the user to control speed of any object or individuals within a certain range from the user, turning the user into a Speed' Human (スピード人間 Supiido Ningen). Hayaku is the Japanese word for "quickly". It was eaten by Pablo Doni.

Usage
Pablo uses the fruit's power to control the speed of his attacks as well as being capable of controlling the attacks of his opponents, most often by slowing down his opponents. He can also speed up his own attacks to increase the damage he is capable of producing, most often producing devastating damages.

Attack List
All his attacks of to date is listed under the Rules of Speed category.
 * X2 Punches : Pablo doubles the speed of his punches, most often catching his opponents off guard at his sudden increase in attacking speed. This is one of his most commonly used attacks and is usually the opening punches for a fight, although it is not the strongest in his arsenal of attacks.
 * X4 Hits  : Pablo further doubles his already doubled attack speed. This is usually used for the damage it is capable of and not of the speed, as it should be noted that as his speed increases, the damages of his attacks are increased but the accuracy of the blows are simultaneously reduced.
 * X8 Blows  : Again, Pablo doubles the speed of his already law-defying quick punches. This speed is usually used by Pablo on quick succesions, as at this rate of attacking speed, it is difficult for Pablo to place much focus on its accuracy to be used for long durations of hits. This is Pablo's much preferred speed rate for attacking.
 * X16 Knuckles : Additional doubling of his attacking speed for incredible increase in attacking power, Pablo no longer have much accuracy and at this rate of speed, placing a deadly hit to the opponents is more often dependant on luck although Pablo have so far only used this speed rate on a few numbers of battles. It should also be noted that a misfired punch at this speed rate is still devastating even if hit in not vital points.
 * X32 Barrages  : This is the only speed rate of Pablo's attack that he can conciously control, sacrificing accuracy for damage. At this rate, any opponent that is within his range of control is at high risks of being hit due to the attack's almost-random misfiring nature.
 * X64 Random  : The fastest doubling speed so far seen produced by Pablo. As noted by the name of the attack, the hits of Pablo's attacks at this rate is of random and although he can still conciously use this rate, he no longer have any control over its accuracy, and often used by Pablo in dire situations as this rate is harmful to both himself and his crew, as well as his opponents.
 * Slow Mo  : Pablo slows down the speed of any individuals or objects within his range of reach to a point where a thrown object can be seen moving slowly in mid-air and can be easily dodged.
 * Super Slow Mo  : Pablo decreases furthermore the speed of any individuals or objects within his range, but only to a certain short amount of time only.
 * Pause  : The movement of any individuals or objects is completely stopped by Pablo when using this move, and can only moved if "Play" is used by Pablo or after 10 seconds have elapsed. This is commonly used by Pablo to stop his opponents and while his opponents is stopped, Pablo unleashes his speedy attacks. It is seen that when an opponent receives damages during "Pause" no effect is seen until movement of the opponent is returned where the damage is seen to accumulate.
 * Play  : The counter-effect of "Pause", where this returns the normal movement speed to any individuals or objects rendered motionless by Pablo's "Pause". This move is usually seen used in combo with "Pause".

Strengths
The main strength of this fruit is that it allows the user to control speed, movement speed or attacking speed alike. It is seen to allow the user to control the speed of simultaneous objects or individuals at a single given time, and no known limit of number of objects being able to be controlled is observed as of yet. The speed limit is also not seen yet, and it is currently observed to correspond only to the user's ability and physical limits to conciously controls the speed.

Weaknesses
As of now, the current user of the fruit, Pablo is seen to being unable to control the accuracy of the attacks as the speed of each doubling increases. There apparently also appears to be a time limit to certain speed rates. Besides those, the user suffers from standard Devil Fruit weaknesses.
