Supernatural is an American television drama series created by writer and producer Eric Kripke. It was initially broadcast by The WB network from September 13, 2005, but after the first season, the WB and UPN networks merged to form The CW network, which was the final broadcaster for the show in the United States by the series' conclusion on November 19, 2020, with 327 episodes aired. The Winchesters, a spin-off prequel/sequel series to Supernatural developed by Robbie Thompson, Jensen Ackles and Danneel Ackles, aired on The CW for 13 episodes from October 11, 2022, to March 7, 2023.
Supernatural and The Winchesters each feature two main characters, Sam Winchester (played by Jared Padalecki) and Dean Winchester (played by Jensen Ackles), and Mary Campbell (played by Meg Donnelly) and John Winchester (played by Drake Rodger).
In Supernatural, the two Winchester brothers are hunters who travel across the United States, mainly to the Midwest, in a black 1967 Chevy Impala to hunt demons, werewolves, vampires, ghosts, witches, and other supernatural creatures. Supernatural chronicles the relationship between the brothers, their friends, and their father. Throughout the seasons, the brothers work to fight evil, keep each other alive, and avenge those they have lost. In The Winchesters, Dean Winchester narrates the story of how his parents John Winchester and Mary Campbell met, fell in love and fought monsters together while in search for their missing fathers.
Supernatural features many recurring guests that help Sam Winchester and Dean Winchester with their hunts and quests. Frequent returning characters include hunter Bobby Singer (who becomes a father figure to Sam and Dean after season two), Castiel (an angel), Crowley (a demon and the King of Hell), and Jack Kline (the Nephilim). The series also featured recurring appearances from other angels, demons, and hunters.
