Challenge 01 – HP x Supernatural. (the tv series)

I've never seen one of those! It would be interesting to see those two mixed up! So, should anyone choose to accept the challenge these are the rules:

01 – Harry is given up for adoption as soon as he's placed at the Dursleys.

02 – Harry is adopted by the Winchesters and is 2 years younger than Sam.

03 – When the Winchester house is burned down, besides the fire, there MUST be some magical force behind it. (not the Death Eaters)

04 – Harry must be able to perform some sort of accidental magic, preferably by vanquishing some demon or vengeful spirit (or calming them), that leads to Harry being sent out in hunts.

05 – Harry MUST become a hunter.

06 – The Winchester brothers should come to England/Scotland and supervise Harry's schooling as a Wizard. (it would also be good if Dean and Sam had other unusual abilities besides being hunters) He should also be at least 14 (or older...) by the time the Hogwarts staff finds him and brings him to Hogwarts.

07 – It is discovered that Voldemort is being possessed by a demon, preferably not the one that killed Sam's girlfriend.

08 – After the exorcism Tom Riddle is discovered to have been a hunter before possession. (he might or might not travel with the Winchesters.)

09 – Theory of conspiracy is encouraged, with something bigger and utterly evil being preferable.

10 – Harry x OC is highly discouraged.

11 – Finally... we have demons, we should also have good spirits, half-angels and the like around.

Now a few ideas I had on my own for this story (no one is forced to accept those ones):

Tom becomes some sort of older brother/father figure for Harry. (slash if someone wants it)

Snape as a half angel who helps exorcise Tom. (this one encouraged by Rickman's interpretation of Metatron in Dogma)

While not able to perform magic nor having his brother's high sensibility, Dean was blessed by a full 6-winged angel at the age of one, therefore being able to send spirits and demons and any dead-like being to the other world without much trouble or repercussions for his soul. His blood also being poisonous to vampires.

Trelawney (did I spell that right????) being a true Seers who has the ability to See things at will.
