One was in a bdsm au where Fury was listed as Clint's emergency dominant after Phil died and he ended up transferring him to Tony who drugged him a lot and was abusive. Steve rescued him and they went on the run for a while.
There were a couple where clint got seriously ill after Loki's control. He had seizures and constant pain, I believe he died at the end of one. He became Stark's head of security in one.
There were a few ones where he was tortured. In one he was thought dead and was accidentally found on a random shield op after a year in captivity. He was heavily injured and scarred, he had a pretty nasty gag that endes up giving him a glasgow smile. There was also one set during catws where clint became paralyzed and ended up running an underground shield reacue network. He became known as the Handler.
There was also a wip involving William Cross and a mutant Clint fic where he was basically a walking bomb. He self immolated in the end after Phil died.
These fics have been removed from ao3 but i would really like to re-read them. I wanted to see if anyone had them downloaded or had an old link to one of them so I could check the way back machine.
I'd be grateful for anyone's help, this was one of my favourite series.
