Lycaon

Lycaon was the first werewolf and the former king of Arcadia.

History
Lycaon was once a human king of Arcadia, the son of Pelasgus and Meliboea. He tested Zeus, who was a guest, by serving him human meat, the meat coming from one of Lycaon's sons, whom he had murdered just for the occasion. He also ordered assassins to attack Zeus while he slept to test his immortality. Zeus became angry as a result of his actions. As punishment, he turned Lycaon and his fifty remaining children into werewolves, except for Nyctimus, the child Lycaon slaughtered and tried to serve to Zeus. Instead, Zeus resurrected Nyctimus and made him the new king of Arcadia, banishing Lycaon and his werewolf children from the land.

Lycaon served as the alpha to the original werewolf pack, and they travelled from village to village, town to town, until eventually, Lycaon died of old age. After Lycaon died, his pack split up into several different packs, each pack going in different directions.

Trivia

 * It is believed that because of Lycaon's act of cannibalism, a mutt now has to eat the heart of their maker (the one who turned them) in order to be cured.
 * Technically, Lycaon never fathered any pure breds. Lycaon himself was technically a mutt, and so were his fifty children. However, because they were the first werewolves, they were far more powerful than any mutt or pure bred.
