Derek Hale is one of the main characters on MTV's Teen Wolf.
Derek initially served as a mentor to Scott McCall, but the relationship soured after Derek became an Alpha and began making choices Scott found immoral.
Despite this, Derek has remained loyal and continues protecting and fighting alongside Scott against numerous supernatural threats.
Derek was born into a family of werewolves. His mother, Talia, was much respected within the werewolf community meaning Derek came into contact with members of a number of other packs.
The process didn't take and, to end her suffering, Derek killed her.
Having taken an innocent life, his eyes changed from yellow to blue.
Sometime later, Derek entered into a relationship with werewolf hunter Kate Argent. She used him to gather information on his family making him an unwitting accomplice to the arson fire at Hale House that killed most of his family.
After his Uncle Peter killed the conspirators involved in the fire, Derek killed him and took the status of Alpha Werewolf.
Kate Argent somehow physically regressed Derek back to the age of 15. While he was eventually restored to his proper outward appearance, he lost all of his werewolf traits and abilities.
Derek apparently died for a little while in Mexico. The whole process - losing his abilities and dying - had been one of evolution. He now has the ability to shift his body fully into wolf form.
The Alpha Pack tries to get Derek to kill his pack to become like them. He finds his sister Cora, long thought dead, and loses two of his Betas and his Alpha status.
Derek is losing his werewolf abilities thanks to Kate, but he later evolves into a full wolf and gains his abilities back. (read more...)
- Derek possessed all of the abilities and weaknesses of a Beta werewolf until Season 4. At the end of Season 4 he develops the ability to shift into full wolf form, and seems to have regained all his werewolf powers.
