Peter Hale

Peter Hale, as the The Alpha Werewolf, was the primary antagonist during the first season of Teen Wolf.

His return from the dead was a major highlight of Season 2.

Biography
Peter Hale was born a werewolf and was with his extended family when the Hale House was attacked by arsonists.

He was the only known survivor of the fire and was left comatose and badly scarred in a long term care facility in Beacon Hills.

His werewolf nature allowed him to heal completely, albeit slowly, over the intervening years. He then tricked his niece, Laura Hale, into returning to town and killed her so that he could become an Alpha werewolf and seek revenge on those who he blamed for the fire that killed his family.

His single minded efforts to kill the guilty led to his death at the hands of his nephew, Derek Hale

Very intelligent and calculating, Peter had a backup plan. Just before his death he somehow infected Lydia Martin with a portion of his spirit through which he was able to give her instructions on how to fully revive his corpse.
