1. A fanart of Steve flying the Valkyrie into the ice and Bucky is there as either a ghost or memory saying "I'm with you till the end of the line pal."
2. Any and all fics where Steve is an omega before the serum and an alpha afterwards
2.1. I think there was one where Bucky starts off as a beta and thanks to HYDRA's experiments ends up as an alpha. It was set in the 1940's, then 70 or so years later in the future. I'm pretty sure Tony was being an arse.
2.2. or where Steve is and omega and keeping it secret from everyone else and is pretending to be an alpha.
2.3. also where Steve is an omega and Captain America is an alpha (they are the same person).
3. Any and all fics where Steve is an omega and both tops and bottoms for Bucky. I think there might have been an A/B/O fic where Bucky is the alpha.
4. And last but not least a fic where HYDRA experiments on both of them expecting Captain America to be the alpha but he instead turns out to be an omega and his Sergeant is the alpha instead.
Thanks in advance. Remy
