"Supernatural" main cast members Jensen Ackles and Jared Padalecki previously teased the waiting fans with the upcoming Season 9 through the Facebook exclusive promo video. Now, it is Misha Collins and Mark Sheppard's turn to excite the viewers with the fast approaching premiere of "Supernatural" Season 9.

The two actors were in full character in the latest "Supernatural" promo video as the fan-favorite angel Castiel and the demon Crowley. The brief promo video shows Mr Sheppard opening the video as the King of Hell Crowley and introduces himself.

Then, Misha Collins appears as Castiel with the signature trench coat and the angel-versus-demon-like promo video began. "No need for blasphemy," Mr Collins warned co-star Mark Sheppard. However, Mr Sheppard's Crowley character does not pay attention with Castiel's opposing response to his messages for the "Supernatural" fans.

"Reminding you to watch the all new season of Supernatural on an all new night - Tuesdays," Crowley stated. He further added: "Do this for me and I'll give you my eternal thanks" but Castiel warned that it is "not something you want."

"The only thing you have to give in return? You guessed it. Your soul. No biggie," Crowley continued with Castiel looking disgusted while giving his response: "That's a very big biggie." Castiel further encourages the viewers to not listen to Crowley's message or deal "except about the Tuesday thing."

"That you should listen to," Castiel finally declares before sharing a look with Crowley. Fans are looking forward to a lot of exciting things for these two characters aside from the Winchester brothers.

Previous reports have revealed that angel Castiel will completely transform into a human being in "Supernatural" Season 9, making him powerless. Castiel must deal with his new found humanity and experience the stuff that humans do like eating, bleeding, doing laundry and even falling in-love.

Crowley, on the other hand, will be affected health-wise after the crazy ritual he did with Sam Winchester last season was put to a stop. Fans can watch Castiel and Crowley back in action when "Supernatural" Season 9 premieres on Tuesday, October 8, at 9 p.m. ET on the CW network.
