Derek Hale

Derek Hale is a beta type werewolf. He comes from a family or pack of werewolves that were almost wiped out in a fire at their home in Beacon Hills some years prior to the events of the first episode Wolf Moon. Only Derek, his sister Laura Hale and his uncle Peter Hale, now non-responsive and badly scarred, survived the fire. The cause of the fire is unknown at this time.

Laura Hale is killed and cut in half just prior to the start of the series.

Scott McCall initially blames Derek for biting him and turning him into a werewolf. Derek claims he is not responsible, instead another werewolf, "The Alpha", is the one that bit Scott.

Derek has assumed the role of mentor to Scott, explaining what it means to be a werewolf. He has also attempted to steer the younger man away from The Alpha since Derek claims the beast wants Scott to kill with him and join his pack.

Complicating Derek’s life further, hunters have come to Beacon Hill in search of the Alpha.

Hunter,Kate Argent, shot Derek with a wolfsbane tipped bullet in Magic Bullet. The bullet poisoned him bringing him near to death.

Lead Hunter, Chris Argent, believed Derek knew the identity of the Alpha and ordered that he not be harmed, but when Derek revealed to Kate that he did not know, she tried to kill him.

In Heart Monitor, he is attacked by the Alpha at Beacon Hills High School and is shown with a massive amount of blood pouring from his mouth. He may or may not have survived the attack. thumb|right|311px
