Summary
Losing one's memory takes more than past events from you; it takes your very core. With no idea who she is or was, and no recollection of how she got her powers, Aleah must adapt to this new and foreign world or submit to those who would control her.
Waking from an endless sleep, Aleah is saved by a group called The Avengers when she stumbles into the midst of their battle. A bond quickly forms with their leader, Steve Rogers, but will a forced betrayal mean the end of any future alliances? When her bloody past and ties to HYDRA and The Winter Soldier come to light, will Captain America continue to fight for her redemption or will he cast her out like all the rest?

Summary
“Excuse me? How did you get that?” Yelena questioned angrily. Ava was sitting with her legs swinging in her white tracksuit pants and Pearl Jam t-shirt, as if Yelena had completely unfazed her.
“I opened the box and I got a pop tart.” Ava replied smugly.
“And how the hell did you get that open?!” Yelena was stunned to her core.
“Well, let’s just say that, from one child spy to another, it wasn’t hard to figure out. You and I are the same.”
“Yes, but didn’t you see that the box specifically says ‘Yelena’ on the top? Those are my pop tarts. You took my pop tarts.”
Post movie Thunderbolts*
In a new mission, Yelena and the team spend a lovely holiday undercover at an Ultron doomsday (haha see what I did there) cult camp.
Yelena and Ava Starr find out they might be more similar than they thought, and their current living situation seems to... bring them together.

Summary
A canon complaint story of a *very* slow burn romance between an original character. She is Tony Starks daughter (obviously). Hopefully very long and very sad... Stretches between the end of the winter soldier and thunderbolts, but there will be flashbacks to times before that. Happy ending though!!

Summary
For a brief moment, Illyana can let her tough exterior go, shoulders relaxing and mind slipping into happier thoughts. Such a rare thing for the blonde to do these days. Mostly because she doesn’t allow herself to show weakness, especially with the multiverse falling apart. Again, it’s only brief. Illyana’s eyes flick up from burying herself into Ororo’s shoulder and sees a woman with black and white hair, mismatching eyes, and slightly parted mouth, surprised to see what’s in front of her.
Illyana’s eyes sharpen again. “What is she doing here?”

Summary
ou weren't born in this universe. You fell into it—dragged across time from 2025 into the MCU, unaging, untraceable, and unseen. While the world turned through war, heroes, and apocalypses, you watched from the cracks. An observer. A ghost in history.
Campbell—your counterpart, your anchor—was pulled into the stars. While you walk Earth's shadows, she drifts through galaxies, monitoring gods and monsters alike. Across time and distance, you send each other hidden messages through cosmic anomalies.
You watched Steve Rogers before he was frozen. You saw Tony Stark declare himself Iron Man. You were there in Sokovia. In the Red Room. On the rooftops of New York.
You never interfere. Not unless Campbell is in danger.
Not unless someone touches the timeline.
Not unless it’s personal.But now… something else is watching you. Something that doesn’t belong.
And the timeline is beginning to break.

Summary
Saoirse Quinn never expected to become an Avenger.
Haunted by a voice in her mind that isn’t hers, she’s more comfortable behind blueprints than on the battlefield. But war doesn’t wait for readiness, and neither do ghosts. Pulled deeper into the Avengers’ world, Shay must navigate tangled alliances, dangerous missions, and a power growing inside her that she barely understands.
As HYDRA's legacy refuses to stay buried and new threats rise from the wreckage of old experiments, Shay finds herself fighting on every front. The pressure mounts, and so does the cost. Her past won’t stay quiet. And Arnim Zola—the voice buried in her mind—is beginning to get louder.
Through it all, her bond with Steve Rogers grows more complex with every mission—rooted in loyalty, laced with feeling—but it’s the unexpected pull toward Tony Stark, whose sharp intellect and stubborn loyalty challenge her in ways she never expected. Their connection is electric, unexpected, and deeply human.
As the world teeters on the brink, Shay must confront what it means to reclaim her mind, her magic, and the future no one thought she deserved.
