What creatures would you introduce: Kappa, Orang-bati, hiru, Chupacabra, Spring-heeled Jack, melon heads, Pukwudgie and thunder birds
Any past characters you'd have return? Jo, Ash
What would be the big story arch: I Would have the brothers trying to stop Malphas who possesses important world leaders in order to start Armageddon. They could attack different countries, polluting the environment and the supernatural world becoming every day knowledge.
What would be the big bad: Revenged-fueled and unstable Michael
What creatures would you introduce: Aswangs; River hags, like Jenny Greenteeth; Wampus cat, but scary; Two-face/sharp elbows; a Kraken in a lake; mermaids, not the zanna kind, the murderous kind; a basilisk; Spring-heeled Jack - mentioned in the Benders, but as we know, it was the Benders, not Spring-heeled Jack; Koschei; Succubi and Incubi; and better hybrids than Jefferson Starships.
Any past characters you'd have return? Since Pamela is dead, Missouri, but if Pamela could come back, that'd be great.
What would be the big story arch: Michael gets out of the cage. He's unstable, as Lucifer has said, and is done following what he thinks is Chuck's plan. The Winchesters don't stop him for a change, and he succeeds in creating an Apocalyptic-landscape across the world in a relatively short amount of time. There are more monsters than people when he's done, and they're all fighting over a limited food source. The job then turns from trying to prevent the bad things from happening to saving as many people as possible now that the bad thing has happened.
Any side stories: Possibly different monster and demon factions rise to confront one another over human resources, and these could be the focus of the next season after Michael is ultimately defeated.
The Archangel Michael has figured as the greatest and most revered of angels in many scriptures and spiritual traditions. Michael is a leader of armies.
He's been referenced many times by the Show over the seasons. But who is Michael? We've never met him and apparently Dean is his vessel. Seems like enough meat there for maybe a season.
Michael might be a little crazy and dark from his time in the cage. Dean's fought monsters all his life. I think he's a little crazy and dark too. (There are some cool sexy images of Dean Winchester as the Archangel Micheal online but won't let me post here).
However, I'm bracing myself for more BMOL, fast growing devil baby, and .... sigh, Lucifer.
Not sure I would have an overall big bad because that means we have to have a mytharc and those have not been working out too well. I would probably go for a virus brought to earth by “Angels” who have travelled to other universes – this might help to bring Cas into the fold although I would want the rest of the angels to decide they want nothing to do with earth as I haven't liked them for some time.
I would definitely want lots of good MOTW episodes with new and innovative monsters i.e. no vampires or werewolves! Gargoyles, basilisk and googling a few – Wolpertinger, Gjenganfer – lots and lots of potential monsters for them to fight.
I do also rather like CluelessDrifter's idea of an apocalyptic event but they would have to do it properly i.e. deserted towns etc and I doubt they have enough money to do a good job.
As for past characters, if we don't include Jody then it is rather limited as most of the ones I would like have been killed off already.
We would not have in the whole season any other guest actors that were so clever they make Dean and Sam look stupid!!. Cas should be included with a proper storyline which they just do not seem to be able to come up with and Crowley, if he is in the Season is not made to look stupid again with Lucifer.
You guys came up with some very good ideas. I haven't reached tweleve yet, but based on your guys dislike of it they must be winging it. Sometimes I wish fans could be in control.
What would be the big bad: The monsters unite under a council of monsters (Kali, Doc Benson, a Dragon, a surviving Starship, a witch and a resurrected Alpha Vampire) seeking revenge against the BoL's rampage.
What creatures would you introduce: Chupacabra, Spring-heeled Jack, Gargoyle, Succubus
Any past characters you'd have return? Revenant Rufus, Lily Sunder
What would be the big story arch: The monsters go to war against the hunters. They use teamwork and technology to decimate the BoL. Sam takes a John Connor approach and starts leading the surviving hunters to resist the uprising. Dean doesn't want to sacrifice any hunters in the war so tries to do all the hunts himself with Sam in tow. The Thule, The Stynes, The Grand Coven and The cult of Fenris unite as well to regain their lost power and get revenge on the winchesters. (Nazi werewolves and Revenant Rufus as their hunter).
Any side stories: Heaven decides to stay out of Earths business. Cas becomes the last Angel protector and joins the monster war with Lily Sunder. Crowley and Rowena play all sides but go team Winchester when The Thule and Stynes start stealing all the power.
