The Amazons are an all-female race of near-human creatures.
History and Culture
They were created by a meeting of the pagan gods Ares and Harmonia, creating a tribe of warrior women who had no need for males, except for reproduction. At some point they had a war, and their numbers were vastly depleted, as such they made a deal with Harmonia to save them from extinction, and she made them more than human, turning them into monsters.
In the present day, the descendants of the original amazons, having moved to America at some point, starting mating in Miami and then Chicago, causing a series of deaths. In 2011 they began again; this led to the creation of Emma, when one Amazon, Lydia mated with Dean Winchester.
The brothers were able to kill one Amazon, and Emma, but the other Amazons fled before they could find them.
Tradition is very important to them. After mating, the child created must kill their father as a sign of initiation, they do this by first cutting off his limbs, and carving a symbol into his chest, before killing them. Children were taken to learn on the day of their birth, there they are trained and tortured to make them strong. Before their initiation, they have a mark burned into the skin.
Amazons have superhuman strength, enough to throw a grown man through a wall. They also matured incredibly fast. The women becoming pregnant hours after intercourse, and giving birth, hours after that, the child continued to mature, growing to late teens only two days after birth.
Despite this, they can be killed as easily as a normal human.
