Dean Winchester

 Dean Winchester is a hunter, and eventually part of the Men of Letters. He is one of the leads of Supernatural along with his younger brother, Sam. He is also a good friend of the angel Castiel.

In addition to being Sam's older brother, Dean is the son of John and Mary Winchester, the older paternal half-brother of Adam Milligan, the grandson of Samuel and Deanna Campbell, and the second cousin of Gwen and Christian Campbell. He is also the grandson of Henry Winchester. Later on, Dean is revealed to be the true vessel of the Archangel Michael, making him a true servant of Heaven. He would also be deemed worthy by his ancestor and Knight of Hell Cain, also an older brother who wanted to keep his brother from being corrupted by Lucifer, and thus would be given the Mark of Cain.

Personality
Dean is shown to be understanding at times, kind, funny, mischievous, and, in contrast to his younger brother, a little immature. At an early age, Dean was trained by his father, John Winchester, to hunt and kill creatures of the supernatural. However, unlike his brother Sam, he did not resent his father for having him "raised like a warrior." He seemed to prefer hunting the supernatural over any normal "apple pie" life. However, by Season 7, following all that he has seen and done, Dean admits to Eliot Ness that he no longer wants to be a hunter and would give it up if he could. Dean is an avid fan of classic rock music. Many of his aliases have included the names of famous rock musicians. He is known to use crude humour, make sexual innuendos and indulge in pornography (especially for Busty Asian Beauties).
