Centaur

Appearance
A creature with the upper body of a human and lower body of a horse.

Origin
The first centaurs were born when Hera attempted to trick Ixion, the king of Lapiths, to accidentally reveal his love for Hera to Zeus by using Nephele, a cloud nymph. However, Ixion instead seduced Nephele and Centaurs were born.

They also appeared when Zeus spilled his seed on the ground of Cyprus, in frustration, after Aphrodite eluded him. These centaurs were then born, and these ones had horns.

When Zeus put Lamian Pheres to guard Dionysus from Hera, Hera instead transformed them to ox horned centaurs.

They are said to be wild but also good with healing and archery, and inhabit Magnesia, Mount Pelion in Thessaly, the Foloi oak Forest in Elis, and the  Malean peninsula in southern Laconia.

Riordanverse
The tribes of Centaurs have evolved and become known as "The Party Ponies." They love root beer and partying and using slang terms like, "Dude."

Chiron, unlike his brethren is a teacher at camp half blood, and trains demigods and heroes to this day.
