Centaurs

Centaurs (ケンタウロス) are artificial creatures of Punk Hazard, which were originally humans and afterwards got animal parts due to Trafalgar Law's Devil Fruit ability. They constitute Caesar Clown's army.

Appearances
Centaurs seem to have different variations, not following the ancient Greek and Roman myths of being half horse from the waist down, but instead having the lower half being any kind of animal. Some like Smoothie follow the traditional myths by being a horse centaur.

Formation
Almost all the current centaurs were originally full human pirates who got caught by Marines and deported to Punk Hazard as Vegapunk and Caesar Clown's guinea-pigs.

Due to the first explosion of Caesar's experiment on H2S gas of four years prior the present, they lost the use of their lower bodies. When Trafalgar Law arrived on the island, he used his Devil Fruit ability to give them new legs, creating the centaur army for Caesar.

Exceptions are constituted by Brownbeard and his crew, who lost their lower bodies use due to their fight against Basil Hawkins.

Disbandment
After Caesar was defeated and captured by the Straw Hat Pirates and Law, the centaurs who were petrified by Caesar's new H2S gas experiment was saved by their comrades, and were all arrested by G-5.

Trivia

 * Just before meeting the real centaurs, Luffy used Kin'emon's lower body to make up a fake-centaur.
 * Among Law's modifications include other types of human-animal hybrids that have different chimeric-design than the centaurs, such as ones who take on the appearance of satyrs, and Monet as a harpy.
 * Even though he is not a satyr, Caesar Clown is shown to have the same sheep-horns.
