Supernatural is a TV series that aired on The WB from September 13, 2005 to May 4, 2006 and The CW from September 28, 2006 to November 19, 2020 for fifteen seasons.

Guest Characters

(Note: You can barely hear the sign off of Jack Killian, the radio host protagonist of Midnight Caller, through a car radio with heavy static. The closed captioning does clearly say “This is your host Jack Killian on KJCM 98.3 FM, and good night, America, wherever you are.”. Midnight Caller is from the same executive producer and corporate owner as Supernatural and the closed caption is highly specific so I’ll list it even though this one is a barely there easter egg.)

Outgoing Crossovers

(Note: The Winchesters takes place in an alternate universe from the original Supernatural series with rebooted characters. The crossover characters listed above are the versions from the original show.)

Spinoffs & Outgoing Cast

(Note: The Winchesters involves Dean from Supernatural going to an alternate universe so the versions of his parents John and Mary in The Winchesters are not technically the same characters from the original show.)

Mobile & Web Series

Ghostfacers, a web only spinoff, aired ten episodes on the CWTV website from April 15, 2010 to May 13, 2010. One bonus episode aired on October 11, 2011.

Cartoon Crossovers & Follow Ups

Supenatural: The Animation was an anime adaptation of the series that ran from February 9, 2011 to April 27, 2011 for one season. It adapted several stories from the first two seasons of Supernatural but also expanded on the universe.

Supernatural crossed over with Scooby-Doo, Where Are You? in the season 13 episode “Scoobynatural”. Sam and Dean are sent inside of the Scooby-Doo episode “A Night of Fright Is No Delight”.
