John Winchester (Supernatural) [SEP] Introduction
John Eric Winchester is a fictional character on The CW's series "Supernatural", and the protagonist of the comic book spin-off series "". Developed by series creator Eric Kripke, the character is mainly portrayed by Jeffrey Dean Morgan. John is the father of Sam and Dean Winchester, the show's protagonists. Seeking revenge after his wife Mary was killed by the demon Azazel, John Winchester became a hunter and raised his two sons to fight the supernatural. John disappears early in "Supernatural", and the first season revolves primarily around Sam and Dean trying to find him. Morgan was also filming episodes of "Grey's Anatomy" while the first season of "Supernatural" was under production, and future appearances of the character were hindered by his busy schedule.
