Summary
“Ava,” he began once more, not even caring how drained and desperate he sounded while he looked back at her. “Just don’t take this the wrong way, alright? I’m not great at… spelling things out like this. But I think if I don’t say it straight, you’re gonna miss what I’m trying to tell you.”
"What?"
She somehow looked more offended, but Bucky had no choice but to ignore it.
“I’ve been trying to seduce you.”
“I beg your bloody pardon?” she squeaked, her mouth finally dropping to the floor.
“I’ve been trying to seduce you for over three years now, since I brought up the idea of having a book club together."Or: Bucky Barnes had been trying for three years to seduce Ava Starr…if only she had actually noticed.

Summary
“Why don’t you go back to sleep, hm? I’ll be back in a few hours, Sunshine. I’ll just…Bob?” Yelena was a bit startled when he unexpectedly tensed, his eyes snapping up suddenly. Her brows furrowed. “You okay?”
For a split second, something unfamiliar flickered across his face.
It was too quick to name, but it was enough to make her slightly worried. His arm slipped from around her waist as he shifted away, rolling onto his side with his back to her. Then, he tugged the comforter all the way up.Or: One morning before leaving, Yelena called Bob “sunshine,” and it just about broke him.

Thunderbolt’s Child Protection Service: Tiny Widow and The Puppy by HerBitterSweetness

Tags
Summary
When Walker and Ava hadn’t heard back from Yelena and Bob for a week, they knew something was off. Even though they had moved out two years ago from Watchtower to start their happily (disgusting) married life in Yelena’s quiet Ohio childhood home, it wasn’t like them to go radio dark like this without a snarky check-in or emergency piggy-sitting request.
So, they decided to check.
What they found instead was a feral-child version of Yelena, with her knife skills intact, a pint-sized Bob that looked like a cornered pup, and a house that screamed: “failed experiment gone wrong.”
Now it’s up to these reluctant Thunderbolts to play child protection services until they figure out how to reverse it while trying to stay one step ahead of a Red Room child assassin who wants them dead and whatever catastrophic power might still be buried inside the other one.
Or: Reluctant Thunderbolts* turned reluctant nannies to 8-year-old child assassin Yelena and terrified Bob, who follows Yelena like a puppy.

Tags
Summary
Ava Starr remembered that once upon a time, she liked hugs.
At least, that’s what she was half-heartedly convinced was true.
Though it felt like some distant, borrowed memory of warmth that didn’t quite belong to this version of her anymore. Back then, contact hadn’t felt like static crawling under her skin or like the world threatening to tear her apart at the seams.
It was warm and made her feel…happy and safe, in a way she couldn’t quite define anymore.
She thought she was past the point of missing it until she was hit with a toxin that made her body ache for contact or risk freezing to death.Or: Touch-starved Ava and the Thunderbolts team helping her through it, featuring #WinterGhost and a dash of #Boblena

Summary
Robert “Bob” Reynold wasn’t sure what he expected when he came down from his room that morning and found a strange-looking dog-monument sitting right on the kitchen counter. Yet he definitely didn’t expect to be turned into a giant golden retriever of all things.
The only way to break the curse?His beloved must recognize his name and say his name!
Except he doesn’t have a beloved the last time he checked.
Or: Bob gets turned into a fluffy golden retriever, and the only way to break it is your true love recognizing you, no matter what form he’s in—and Bob has absolutely no idea who that could possibly be.

Summary
Bucky feels his shoulders loosen the moment the Watchtower doors open with a welcoming hiss.
Except, when it did, the first thing to hit him straight away--
--was the sound of Ava moaning.
Deep.
Guttural.
The kind that he often pulls out of her with his own mouth.
And for a wild moment, the world absolutely refuses to make sense.
Then Bucky was moving.
Just to be assaulted with:
"Oh my god, John. Please. Don't stop. Don't you dare stop."
...Walker.
Of course, it's John Walker making Ava moan like that.

or
Bucky comes home from a mission only to find John with his gigantic hands on Ava in a way he doesn't fucking like.

Summary
These were the three, 100% undeniable facts of the matter:
Fact 1: Ava Starr was pregnant, and Bucky Barnes was the father.
Fact 2: Both of them are completely oblivious of Fact 1.
Fact 3: The only living soul who did, in fact, know Fact 1 to be truth was John Walker.
(Oh, and Alpine too, of course.)

Summary
All love ever does is break, and burn, and end.
At least, that’s what John Walker thought. And so, he kept his feelings for Bob Reynolds under lock and key, hidden behind the walls he’d built around his heart.
One thing about walls, though, is they can be broken down.

Summary
Trapped in a gray life in the cold streets of Manchester, Bob learned far too early that home is not always a safe place. Silence became his refuge, books his escape, and loneliness his only companion. Until one day, something impossible happens and the door to a wonderful world opens before him.
Bob never imagined that saving a cat from the bullies at his school would be the beginning of a chain of extraordinary events.
“Welcome to Hogwarts School of Witchcraft and Wizardry.”
“Wait… what?!”
The man in the trench coat sighed tiredly, running a hand through his white hair.
“You’re a wizard, Robert.”
And the magical and fantabulous adventure of Bob Reynolds is only just beginning.

Summary
Reader has been a vigilante for the last year–exposing corrupt elite, fighting off street thugs, speaking out against the government tightening its iron grip on superheroes. All of it while also working a full time job at a cat cafe. When arrested by the New Avengers and given the choice between prison time or joining the team, they join the team. They think it’ll be full of the self-righteous assholery of everyone else in power, but as they get closer to the team, they realize that everyone is just as trapped as them.
When a new villain makes an appearance to try and kidnap Reader for reasons they won’t detail, the team has to worry about the safety of their two most unstable members and prevent them from falling into manipulative hands (besides Valentina, of course).
What happens when Reader is kidnapped by this villain? What lengths are the team, and especially Bob, willing to go to to get them back?

Tldr: Reader is the living embodiment of sunlight while Bob deals with Void & Sentry while simultaneously keeping each other alive by trauma bonding like neglected shelter dogs -

Summary
John believes he's a difficult Sub. That handling him is agony for any Dom trying to subdue his overwhelming rudeness. However, he couldn't be more wrong when he himself provokes Bob to give him orders. Gentle and warm, without forcing him.
How can he surrender to someone who treats him tenderly, when his whole life has been a war? It completely disarms him. And, even if he tries to deny it, Bob is unlike anything he's ever known. It makes him think that no matter how much he wants to deny that Bob isn't his Dom, sooner or later the need to be there for him will be too much.
the summary sucks but i tried my best): -

Summary
Ghostwalker Week tie-in: High School AU (plus a little Meet the Family)
Ava Starr gives her teammates exactly what they need, but when what Karla Sofen needs a punch to the face, her coach is less than thrilled. Pissed that she may be benched for the season before it begins, Ava is pretty sure that her senior year will be as shitty as the previous 17 years. But when she finds a new transfer student in their football kit sitting as if they were under a trance, she may discover that the future may not be as predictable as she thinks.
Except that Karla Sofen will need to eat a knuckle sandwich, with two swift kicks to the stomach while she's down as her side dish. That much is guaranteed.
