1) Are there any fics out there that have Dean that have him as a fairy? He transformed into one or was born one? It can be similar to Nicnivin by henchgirl
2) Succubus or Incubus Dean? or Cas maybe? 
3) Dean with kids - like comforting them, or taking care of them. He doesn't have to be their dad or he can be, I'm not complaining.
4) Creature Dean - from an elemental to a werewolf, any are accepted!
5) Dean or Cas with a tail (any kind)
6) Soul bonded/connection Destiel

Slash and gen is fine.
Destiel (is preferred greatly) or Debriel is appreciated.
Please no Wincest or threesomes.
