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. Meredith Walker overheard his thoughts and would later enact this plan. (See: The Benefactor)
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.
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.
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.
Later, he is taken by the Ghost Riders and was missing for three months. He and Stiles find each other and reluctantly helped each other to find a way out and slowly earns his daughter's trust and right to be called her father.
When the Gerard recruits Tamora Monroe and reorganizes the Hunters, he initially wants to flee but eventually joins the fight and earns a place as an ally in Scott's pack.
