Lydia Martin is a main character and the current female lead of Teen Wolf. She is the daughter of Natalie Martin and Mr. Martin , and the granddaughter of Lorraine Martin and her wife Maddy. When first introduced, Lydia could be as described as a shallow, vain, mean girl who played dumb to hide just how smart she truly was; however, after she became friends with Allison Argent , Scott McCall , and Stiles Stilinski , Lydia began to shed this persona and has since grown into a brave, compassionate person who genuinely enjoys helping others who are struggling, particularly those who have been traumatized by the supernatural like herself.
At the end of Season One , Lydia was attacked and bitten by then- Alpha Werewolf Peter Hale , but in a shocking turn of events, she neither died nor turned into a Werewolf herself, a feat that was virtually unheard of in the supernatural community.
However, she began to hear voices , go into fugue states similar to sleepwalking, and have terrifying hallucinations about Peter, revealing that, unbeknownst to her at the time, Peter's attack had activated the latent Banshee abilities that she had inherited from her paternal grandmother. It was eventually revealed that his attack against her also allowed his spirit to live on in her mind, affording him a connection with Lydia that he could use to manipulate her into resurrecting him with a special ritual on the Worm Moon.
Even after he had vacated her consciousness, Lydia began to be drawn to dead bodies in Beacon Hills , particularly those whose deaths were related to the supernatural, and began unconsciously screaming , which steadily began to worry her. It was eventually revealed to her by Jennifer Blake that Lydia was, in fact, a Banshee, also known as the Wailing Woman, a harbinger of death who was drawn to the dead and the supernatural.
Since this revelation, Lydia has struggled to learn the full scope of her powers and how to use them, often lamenting the fact that her powers were passive, spontaneous, and largely out of her control, unlike the comparatively easier-to-use powers of shapeshifters such as her Werewolf and Werecoyote friends that could be used both actively and defensively. Despite her frustrations, Lydia's ability to sense imminent death has given the pack numerous advantages in battles, though very few people give her credit for just how powerful she is.
