[Warning: Spoilers ahead for season 12 of Supernatural]
While at San Diego Comic-Con, Supernatural executive producer Andrew Dabb teased a new villain for the show's 13th season. Dabb declined to specify any further, but he did state that the new season's big bad would be someone the Winchester brothers are familiar with.
The series' 12th season concluded not only with the death of Castiel (Misha Collins), but also with the reveal that Lucifer has a son. It is assumed that Lucifer's offspring will be an antagonist in the series' next season, but according to the long-running show's executive producer, he is not the only villain on the slate.
Aside from this tease, the producer has been tight-lipped concerning the issue of season 13's antagonists. However, Dabb, who became co-showrunner for Supernatural last season, did give more than a few hints while talking to TVLine. And while these endless teases might serve to rile up the fanbase a bit, it has served to cause more than a few interesting theories.
Dabb revealed, “[Lucifer’s child] Jack is not the biggest threat they are dealing with.” When asked who this familiar face is, the showrunner responded by saying: "It’s an old — let’s call him friend — who we have not seen for many years.” He did go on to clarify that the villain is male and is from an "alternate world." What alternate world could this be? Well, when Dabb was asked if Michael – the archangel trapped in the cage with Lucifer seasons ago – is the upcoming villain, driven mad by his time in battle, the executive producer responded by saying, “I’ll plead the fifth on that one."
Whoever the villain might be, fans were assured that he will cause all sorts of trouble for Sam (Jared Padalecki) and Dean (Jensen Ackles) in the show's 13th season. There is no definitive answer one way or another, but Michael the archangel is as good a guess as any. With Mark A. Sheppard announcing that he will not be returning to portray longtime Supernatural villain/anti-hero, Crowley, it would appear as though the series could use another familiar antagonist in its rotation. Whether or not this villain sticks around past Supernatural's 13th season, however, remains to be seen. Until the show returns this fall (or until Dabb reveals more secrets), fans will have to continue their theories and speculation concerning this mysterious big bad.
The season 13 premiere of Supernatural will air Thursday, October 12 on The CW.
