His return from the dead was a major highlight of Season 2.
Peter Hale was born into a family of werewolves and has always resented that his sister, Talia Hale, reached Alpha status in the pack, believing that place rightfully belonged to him.
When arsonists attacked Hale House, Peter survived while most of the family died. He was badly burned and went into a self-induced coma to heal. While he was out, Peter’s mind raced with thoughts of revenge. He blamed Talia for making the family weak and plotted to kill all the supernaturals in Beacon Hills and remake the town in his own image.
Six years after the fire, Peter seemed to have forgotten his plans for a new Beacon Hills. Instead, he sought revenge on the arsonists who had burned down Hale House. While seemingly still in a non-responsive state and with the aid of his nurse, Peter managed to kill his niece, Laura Hale, and take her Alpha status for himself.
He began building a pack by biting Scott McCall. It was this act that eventually led to the exposure of his revenge plan and Peter’s “death” at the hands of his nephew Derek.
Another bite would be his salvation.
Knowing that Lydia Martin would be “immune” to the werewolf bite, Peter attacked and bit her. Through the bite, he implanted his memories into her just prior to the final showdown with Scott and Derek. Once Lydia recovered from the bite, the memories took the form of hallucinations that instructed her on the means to bring Peter back from the dead.
The plan had to be completed by the second full moon after his death. She found Peter’s body buried under Hale House surrounded by wolfsbane. She then used wolfsbane hidden in drinks to drug Scott and anyone else who might interfere. She collected Derek, now an Alpha, by knocking him out with wolfsbane powder and dragging him to Peter’s body. The full power of the full moon and Derek’s Alpha spark allowed Peter to heal fully.
Peter claimed the return to life left him weak and he stayed near his nephew for months subtly manipulating him. Peter stayed out of a conflict with a pack of Alphas until the very end when he killed a rogue druid and declared himself “The Alpha.”
Peter further insinuated himself into Scott’s group of friends by aiding in the rescue of Stiles Stilinski from possession by a Nogitsune and in the process learned that he has a daughter. He believes Talia took the memory of the baby and her mother from his mind.
It is later revealed that, after the fire, Peter had been hospitalized next to an unconscious Meredith Walker. Though he was comatose, she was somehow able to pick up his fevered thoughts of revenge on the entire supernatural population. This became her inspiration and a road map for The Benefactor plan.
He is still bitter about Scott's rise to True Alpha status and wants to regain the status and power his family once enjoyed. He feels that the fire and Scott robbed him of his birthright.
He currently resides at Eichen House in a special ward for supernatural threats.
