The Slayer Essence is actually a trapped Knight of Hell. When the Shadowmen try to force Buffy to accept more power, the Knight is set loose. Buffy and the Knight come to an arrangement where they coexist. Cain becomes aware of her after he gives the Mark to Dean, and goes to her and tries to find out what her big plans are. Cain leads Abaddon to Buffy, which in turn forces Buffy to make a decision to seek out the Winchester's help. She offers to help them kill Abaddon by giving them information that only the Knights are privy to in exchange for actively helping to kill Metatron and getting th...

The order of Dagon decides to move sooner to keep the Key safe from Glory but instead of just Buffy's blood they also combine it with the blood of a hunter.

Buffy is still mad after the fight with the the First. So when she gets a offer to go help in another universe, she decides to take the deal. With the confirmation that she will never have to leave this new universe against her will. She meets the Winchester's.

You can change details, it's fine just so long she leaves to the supernatural universe and meets the Winchester's.

The Scooby gang of session 5 are tormented and picked off one by one, by the Slender man

One of the core Scooby gang is the person that the demon Meg chooses for her host. The host can be from season 1 or 5-8 and the survival of the host is up to the author. Maybe Meg possesses two members of the Scooby gang, one for each canonical host.

I think it would be neat to see the Scooby!Meg being chased by the rest of the Scoobies and what the impact of the demon possession would be. Would Scooby!Meg have a greater impact on Supernatural canon than the two canonical versions? Would Scooby!Meg's host survive the exorcism at the end of season 1? Would the Scooby gang hunt Scooby!M...

There are 2 variations you can choose to base on for this challenge :

1) One of the Winchester Brothers is Reborn as one of the Buffy / Angel Characters

- You can include other Supernatural characters but the story must focus on the person that was reborn.
- You can use the Halloween event for them to remember who they were
- You can NOT include any demons / angels that were dead by the end of Supernatural Season 5 (or whichever season, from 5 onwards, based on what memories you want to give them) [The only exception to this rule is that your Supernatural World is AU,...

What if John Winchester was the commander of the Initiative or the one that they brought in to replace Walsh? He was a former marine with a reputation as being one of the most skilled hunters that was around at the time. What kind of force would he have turned Initiative into? He wouldn't have allowed for some of the crap that Walsh had allowed to happen experimenting would have only been to see the best way to kill the demons.
We've seen what happens when he only had his sons what would have happened if the government gave him the resources to really take the war against the supernatura...

Kind of surprised I haven't seen anything like this yet but here we go. In Supernatural its a fact that instead of going to heaven monsters go to purgatory. With that in mind it makes me wonder what would happen if some of our heroes somehow ended up there. How many of their old foes would they end up meeting in the afterlife of the monsters. And how long could a Scooby manage to survive in a world that was made up of defeated and destroyed monsters. Heck you could even add in foes from other shows like Charmed.

-> Angel or Spike be your main character since their ...

What if Xander was Sam? How you want that to be possible is up to you (though there are suggestions), but make sure that :
1 ) Dean doesn't know until he is near Xander/Sam, and somehow knows it's him.
2 ) Sam pretends not to know anything and asks of a favor from a Witch of the Devon Coven whom he met by accident to do a spell go which he has always been go Sunnydale (Optional)
3 ) He is not abused and Xander's parents are normal parents whom supports him. His morals are from school bullying.
4 ) If you start at Halloween, then Xander decides to dress up as Dean for his Hallow...

Confusion, Mayhem and Sneaking around, OH MY!
A story that includes Dawn and Dean and their budding relationship. The Scooby Gang (Buffy gang) and the Winchesters are friends and now live somewhere (your choice) that is very close by each other, like in the same state close.
I want Dawn and Dean to hide this romance from Buffy mainly because Dean is petrified he is going to get killed by the slayer. So they keep it a secret from everyone causing some serious issues within the newly enlarged gang. I want this to cause all out mayhem. Something like Buffy starts to think Dawn is demon-h...

Halloween 1998 instead of a Soldier Xander goes as a Cowboy. Said Cowboy turns out to be Samuel Colt. And Xander's gun becomes a Real copy of the Colt. When the spell ends Xander remembers everything Colt knew about the Supernatural.

One he uses to Kill The Judge the Other he uses for Kakiotos. When the Scoobies learn about the Mayor Xander hits the road to find the other Colt or the...

I'd like to see what Sam & Dean would think of the Slayerettes. Would they slay Willow, or try anyway. Would they interrogate Buffy? Would any of the Scooby gang be known to the hunters of their kind? Wesley did say he was a rogue demon hunter after all. Would they go after Oz?

My challenge: Sam & Dean witness a Slayer performing her duty and tail her back to HQ and attempt to investigate what the heck they saw by mentioning it to other hunters. Whether that's in Cleveland, Sunnydale, or some other Hellmouth is up to you


Dean trying to hit on a Slaye...
