“B

James “Bucky” Barnes is an alpha. Before hydra, his mated omega was Steve Rogers. The super serum that Steve received muted almost all omega aspects in him. He now firmly presents as an alpha. Until he sees Bucky again for the first time in years, and every omega instinct, buried under an alpha presence, scent, and build, is screaming for their alpha back. Steve goes into heat just based off the smell of Bucky. It’s been too long. And Bucky? The Winter Soldier? His memories may be suppressed under hydras brainwashing but his inner alpha starts screaming for Steve.
