This big bang is for any and all fics dealing with the Supernatural characters in an alternate universe. Want to write about Sam and Dean being werewolves? Or Dean and Castiel in high school? Or how about Jo as a warrior elf queen? Any AU is allowed, so long as it takes place outside the Supernatural universe (although the Endverse and the French Mistakeverse are allowed). RPS/RPF is welcomed.
