Warning
The following stories of mine contain major character deaths. Do not scroll if you don't want to be spoiled. Trust me - they are all better if you don't know ahead of time.
When you Gain the World ... Vamp!Dean, killed by Sam.
A Done Deal - Dean, (as completion of the deal, but he comes back)
One Shall Fall - Dean, (as completion of the deal)
Waiting - Dean, (as completion of the deal)
Samael - Dean, (as completion of the deal, but he comes back), Ruby, Lilith, Sam (but he comes back)
Acceptance - Bobby
When Death Deals, All Cards are Wild - Sam, although it isn't seen.
The Spirit Verse - Dean, (as completion of the deal, but he comes back)
Regeneration - The entire Regen!verse is centered around a future fic in which we find out that Sam and Dean are already dead. Flashback one-shots feature them alive for the most part. Release is the one-shot that is ACTUALLY the death scene.
For the Fallen - Castiel.
Tread Softly - Dean kills Sam.
Rage Against - An a/u of Mystery Spot in which Sam dies instead of Dean
Loss - Lisa, the Impala
Repo Men: The Upside-Down Apocalypse - Pretty much everyone that died in canon seasons 4-5, but all in different ways.
