Diomedes' Horses are one of the world's most dangerous Equidaes (horses, donkeys, and zebras) due to their unnatural behavior to consume flesh from either animals or humans who come into contact. First originated in Southern countries nearby the Black Sea starting at Romania throughout Northern Turkey, the horses were accidentally brought to Greece by merchants trying to sell the horses to farmers. Unfortunately, a few escaped and created a small population within the country. In appearance, the horses vary between sexes with colors ranging from white to black. Males, smaller, are less aggressive and are omnivorous while the females, larger, are more aggressive and are carnivorous. Diomedes' Horses (unlike domestic and wild horses) have sharp, jagged teeth used for ripping food from their victims except for males, which have only K-9s and grinding teeth due to their omnivorous lifestyle. In the wild, females are usually in charge of a herd and are violent toward each other during mating season in which gender roles switch (males are picked by the females instead of the opposite of other animals). Domestication is still possible, but remember to always have in mind that even though females tend to be less aggressive in captivity, they still have a carnivore's thirst for blood.
Diomedes' Horses (shown above) were once part of the twelve labors of Hercules in which he binded their mouths shut with chains. This method is still used today whenever someone wants to 'break-in' the horses for domestication.
