Sorted by fandom. Old ass and not updated, because a) you've probably seen it before, b) I'm not really writing anymore unless you count the whump.
Though yes, I suppose a few of these will be reposted on ffnet. When I get around to it? When is that?
Fandoms are by amount of content, so most of what you're looking for is probably buried under the mountain of Mortal Kombat fic and scraps.
Insane, self-serving crossover bullshit is at the very bottom of the list, irrespective of fandom. XD
I like ";" so ";" is my divider thing instead of ":". I wish I had a more grammatically conscientious reason, but I don't.

Fullmetal Alchemist:
Needful Things: Greed/Everyone
The Human Stain Greed/Envy. Irrelevant consent, blood, bondage, clumsy pronouns, and awkward positioning. Strong language. SLASH.
Reward Response; Greed/Envy, close enough to actual hurt-comfort for jazz improv. Dubcon/noncon (the difference is debatable, anyway.) Blood, swearing, and general manhandling. SLASH.
Hedge Alchemy: Misc.
Can't; Alex-Louis angst, shortly after Ishbal. No warnings/gen.
So, Roy Walks Into a Bar; Roy and Greed meet. Because they so totally should've. Anime-verse AU.
Piecemeal; Ed-focused angst. Unfinished.

The Off-Road to Redemption; Gunn/Faith. Alcohol use, implied sex, awkward/impossible positioning.
Insane, Self-Serving Crossover Bullshit: (The Name Says Everything)
Three of a Kind; Baraka/Mileena/Greed in the same basic AU as "Glitter".
Pavement; the only Baraka/Batman slash ON THE ENTIRE INTERNET. EVER. TRU FAX SRYSLY. Can you believe Mortal Kombat Versus DC Universe is actually REAL? Neither can I. I weep most weepingly, and they are not tears of joy, oh no.
