Summary
Bucky is dead. To everyone else, Steve lost a friend, a soldier. For him, he lost a lover, his rock and crutch. They’d been together for so long that the hole Bucky leaves behind in Steve’s chest is like the remnants of a cannonball shot. Chased by grief, Steve drops the Valkyrie into the ice and thinks that this is it. He'll finally be able to be with Bucky again.
Steve wakes up in a new time, with new enemies and new friends, but the mission is the same. Bring down the enemy, no matter what. When a mysterious figure known as San Dapth makes his way onto the scene, Steve and the Avengers step forward and heed the call to arms. Together, they have to face down San Dapth and bring him to justice.
It's in their fight against San Dapth that Steve discovers something terrifying. He's pregnant with Bucky Barnes' baby. Now he must learn to live this new life without the man he loves.
Hydra learns of Steve's pregnancy. And they'll do whatever it takes to get to his unborn child, including unleashing their greatest asset from the ice—the Winter Soldier.
When Steve discovers the Winter Soldier and Bucky Barnes are one and the same, he must fight to bring back the man he loves.

Summary
Tony Stark finds himself unexpectedly transported from the Hydra base in Siberia to a snowy ravine, where he witnesses the aftermath of Bucky Barnes' fall from the train during World War II.
Realizing he is in some sort of vision created by Wanda, Tony just wants out. Instead, he is forced to experience one harrowing vision after another as the making of the Winter Soldier is laid before him.
Tony struggles with conflicting emotions, torn between his anger toward the man who killed his parents and a growing empathy as he sees the horrific treatment Barnes endured at the hands of his captors. -

Summary
You've always known something was a bit off, about you. You were raised alone, and never knew your father. Your mother never liked to talk about her family. You moved a lot when you were young. You had a broken arm once, that healed in two weeks instead of two months. Oddities that are overlooked by the mind of a child, but start to seriously pile up in adulthood. Now you're fully-grown and attending university in Berlin, just trying to make it through school and make ends meet. Life is blessedly normal. Until it isn't.
Until one night, you're stalked and chased through your own city by a man in a mask, until you're taken by HYDRA and told you carry a powerful genetic legacy in your blood, that you naturally inherited the effects of the super soldier serum from your maternal grandfather — Johann Schmidt, the Red Skull.
Until you're turned into their labrat, designation Subject V-13, as they try and take everything from you in their quest to create a new race of superbeing. Until the man who brought you into this hell in the first place, the Winter Soldier, is charged with minding HYDRA's most-precious natural resource; you.

Summary
James Buchanan Barnes had been through a lot in his life: Fighting in wars, brainwashed and forced to kill for decades, fighting to remember who he was... The hardest part of it all? Finding his place back in the world.
Then, there was you.
You had been someone else for so long, you didn't know how to step back into life.
From being taken to the Red Room, brainwashed, and then taken and experimented on by HYDRA for decades, you and Barnes shared your fair share of trauma, both separately and together.
You had grown close, although it hadn't happened overnight. You hated each other. There were multiple times over the years when you tried to kill each other and almost succeeded. Eventually, you both escaped HYDRA, and the most peaceful years were when you were on the run.
Unfortunately, the world had other plans. You were thrown back into the fight, on a galactic scale this time. Bucky blipped, you didn't. After five dark years, the fight was won, but at a severe cost to both of you.

Summary
The breach of a Nunavut warehouse spiralled a domino affect of events, even more so after Valentina butted into the investigation to offer some documents exposing an organisation never seen post the events of 2014: U.T.I.L.I.S.E., a supposed ally of HYDRA since the very beginning of their creation near enough. Valentina thrusted her team of heroes - the New Avengers, of course - into the spotlight, insisting that S.H.I.E.L.D. needed their assistance to bring down this threat before it escalated even further.
She, too, insisted for S.H.I.E.L.D. to chose her group over the 'Liberty Sentinels' (Sam Wilson's temporary team name), advocating that the mission could be a smart tactic to promote the New Avengers in a more positive light to dissipate the lasting public negativity still tarnishing their reputation.
Reluctantly, without much choice, they accepted.
OR
The New Avengers take up a S.H.I.E.L.D. mission as and Sam and the 'Liberty Sentinels' make their own appearance against Valentina's wishes. Both teams join forces to hunt down an anonymous assassin, a.k.a. the Canine, whilst Sam and Bucky traverse the complications of their not-so-secret situationship.

Summary
The wind howled through the ragged hole torn in the train, cold air ripping past them with freezing teeth. Shards of metal and splinters of wood whirled into the snowy ravine below—everything falling.
Steve’s hand clung to Bucky’s wrist with brutal force, his own arm shaking violently under the strain. Every muscle screamed, his shoulder pulled taut like it might tear free from its socket.
Fatigue clawed at him—merciless, familiar.
Like before the serum.
Before he could protect anyone.But this wasn’t just anyone.
This was Bucky.
He grit his teeth, dug deeper, and tried to drag him up.
Inch by inch.
He had him. He had him—
BANG.

Summary
Nobody cared if a 5 foot nothing, hundred pound kid was smart. It didn’t matter. Maybe people would care in the future, maybe being smart could make a poor kid into something. But not here, not now. Not in 1942.
He couldn’t even enlist.
Or
Steve is distracted when Bucky falls from the train, and the Hydra soldier he hit did not die. Hydra decides to take both Bucky and Steve and attempt to use them to train each other (and create more super soldiers).

He spoke to his captors as they wheeled him away. “Bitte,” he said, “Bitte.”
She had never heard a worse sound - not ever in her life - than the quiet pleading of Captain America.

Or, no one knows that Captain America was held captive and tortured during the War. The Avengers find out in the worst possible way. And there's nothing they can do to stop it from happening again.
Cue lots of Steve whump, hurt/comfort, and Avengers team moments.

Summary
“I don't trust her” Bucky ground out, his position resolute.
“I trust Bob”
“Bob can't even trust himself”
Yelena shrugged the comment off, “We worked for Valentina last time… Now, she works with us”
Bucky threw up his hands in exasperation, “Is that how you'd describe our last mission?” he contested, unable to keep the heat from his voice, “Working with us”
“Look, I don't trust Valentina either-” There was a pause.
“You all know where I came from, da?” Yelena inquired, eyes resting briefly on Bucky, then John, she knew that Alexie had been there.
“The Red Room…” John supplied, unsure what this had to do with anything.
“I did terrible things while I was there…Things you cannot imagine…unforgivable things” the echo of screams still rang in her ears, the snapping of twigs, the dirt flung up against her face, the bite of cold in the air, the spray of blood.
“I'm here because I was given a second chance” Yelena continued, her tone husky but firm.
“If you're asking me to give Valentina a second chance-” Bucky challenged, arms folded across his chest in defiance.
“No” Yelena relented, “Not for her” she cast a glance back to Bob, “For him”

Summary
After a seemingly simple mission goes sideways, Bucky Barnes is captured by an offshoot of HYDRA. Tony Stark—who has no love for him—is also taken while trying to stop them from reclaiming their most dangerous weapon. The two men can barely tolerate each other, yet they’re forced into the same transport, headed to a hidden facility. There, they discover something far worse: HYDRA has been training new Winter Soldiers. If they want to survive—or escape—they’ll have to find a way to trust each other.
Meanwhile, Steve Rogers and the Avengers launch a desperate search. Steve, unwilling to lose Bucky again, follows every lead with relentless determination. When the team finally locates the facility, a brutal rescue unfolds.
But the escape is only the beginning.
