Dean Winchester - Season 1

Season 1

As the season begins, Dean, at age 26, is a hunter; he hunts and kills supernatural monsters. Usually, he is with his father John, but sometimes goes by himself. When his father goes missing, Dean asks for Sam's help to find him. They go in search of their father, saving people from the supernatural along the way, but at the end of the first episode, Sam's girlfriend Jessica Moore dies the same way their mother did.

In the episode "Skin", Dean and Sam battle a shapeshifter responsible for a string of brutal murders in St. Louis, Missouri. During the course of the episode, the shapeshifter assumes Dean's form, causing police to believe that Dean is responsible for the murders. However, Dean kills the shapeshifter while it is still in his form; the authorities officially declare him dead and pin the murders on him.

John finally contacts the boys, revealing that he has been away from them because he is tracking the demon that killed their mother. His affection for his sons could be used against him, so he wants them away from him. However, the family unites as they come into possession of the Colt, a special revolver which John says can kill anything, including demons. The season finale concludes with Sam, Dean, and John escaping from their clash with Azazel, the yellow-eyed demon. While Sam is driving an injured Dean and John to a hospital, a demon-possessed driver drives his semi truck into the Impala Sam is driving, causing massive damage to the car and the Winchesters inside.
