Lydia Martin (Holland Roden) is a main character in MTV’s Teen Wolf. She starts out as a preppy popular girl, who quickly recruits Allison Argent as her new best friend. Later on, she plays a crucial role to resurrecting Derek Hale‘s uncle, Peter. This all gets explained in the third season, as Lydia is revealed to be a banshee. It is also revealed that she is much smarter than she lets on. For instance, she nonchalantly mentions her knowledge of archaic Latin. The rest of the show follows her adjustment to her supernatural powers as well as her romantic relationship with Stiles Stilinski.
