CROSSOVER! Our two favorite pairs of vigilante brothers meet by chance, when rumors of a violent demon bring Sam and Dean to South Boston.

“Oh, not this Smallville BS again, Dean. That’s a myth.” Sam looks up from his manly breakfast of Corn Nuts and Coke to roll his eyes at Dean.

Sam and Dean go to Hogwarts.

An AU crossover with The Devil Wears Prada. What if Sam were a little more…fabulous? Jess never died, John goes missing much later, and Dean. Well. He's in for quite a surprise.

Dr. Brennan is pretty much okay with brother-on-brother action. It's just everyone else who needs convincing.

sequel to Vaughn, New Mexico, Day Interstates were all right in their own way. Nothing better if you had places to be. But Dean couldn’t help hating them.

Dean and Sam are on the trail of a demon who is killing families that share a certain secret. When they run into another set of brothers working the same case, they realize all four of them might be in danger as well.

Dean had them heading towards Golden Valley on I-93 when the semi and the fighter jet went screaming by, blasting at each other with what looked like laserbeams. That was crazy enough, even before both of them smashed into the overpass and stopped long enough to unfold into giant robots. (Crossover with Transformers)

Sam and Dean go to Hogwarts. (spoilers for All Hell Breaks Loose, Deathly Hallows)

Dr. Brennan is pretty much okay with brother-on-brother action. It's just everyone else who needs convincing.

Sam and Dean have always been oddities among the dragonriders; the youngest man to Impress a Bronze dragon in a hundred years and a boy who turned his back on the riders to become a dragon healer instead. But when fate steps in and chooses a far different path for Sam, the brothers and all the Weyrs of Pern will have to come to terms with much greater changes in their traditions.
