Kate Argent "La Loba"

Kate was raised to hunt werewolves and taught her families 400 year history but she had no respect for the code by which the hunters were supposed to operate.

When she was a young woman, she conspired with a number of people to burn down Hale House with a large number of the family locked inside. She got away with the murders for six years. When Peter Hale recovered from his injuries he came hunting for the arson conspirators.

Peter tore out her throat with a deep scratch but Kate's body began

to heal. Suspecting that the scratch of an Alpha would result in transformation, Mexican Hunter Araya Calavera came to Beacon Hills to check. She found Kate's body was healing and transforming and took her back to Mexico.

Kate fully recovered as a Werejaguar, faked suicide, and escaped. She made it to the temple of Mexican jaguar god Tezcatlipoca in a place known as La Iglesia. She was aided by the berserkers there and learned she could control them. She became known as "La Loba: The Bone Woman" and learned from Peter Hale that she also had the ability to create berserkers.

She blamed Scott McCall for the death of her niece Allison and for what she termed "the decimation" of the Argent family. While her plan to kill Scott failed, she managed to escape capture and is currently on the run from the Calaveras and her brother Chris.

Her grave remains in Beacon Hills Cemetery. The gravestone reads "KATHERINE ARGENT 1983-2011"
