FMA: Definitely. Though Roy, too, possibly - he's really hard on himself. And then you can enter the two of them into a feedback loop of woobie-comfort-woobie.

I can see a good fanfic which actually develops the character of, say, Breda or Havoc or Fury (not Hawkeye) and which allows them to fulfill the woobie tropes. You know, Breda has sacrificed himself for the good of the Cause and is broken, can is commanding officer put him back together? And it all takes place in a corner of an abandoned warehouse because they're Hunted. Uh, I'd probably read it ...

(haven't been keeping up with canon lately, btw)
