Iron Hearts: The Stark and Vespera-Calderón Protocol

Marvel's Avengers need someone they can bleed on and break down in front of — that someone is you.

You are Steve Rogers younger sister. Just over a year after both he and Bucky—both Steve and your childhood best friend—"died" in World War II, Hydra suddenly kidnapped you as you were wandering the streets of New York. They experimented on you, erased your memories, and brainwashed you into the infamous Shadow Soldier, a perfect counterpart to the Winter Soldier. Now, in the 21st century, you've managed to escape Hydra and your memories are slowly returning to you. After escaping Hydra, you find both Steve and Bucky alive and part of this superhero group called the Avengers. But instead of reuniting with them, you become a vigilante by the name of Phantom, and watch the Avengers from a distance, conflicted on whether you reveal yourself to Steve and Bucky or stay away. Will the Avengers find out who you are, or will the mystery of the watchful Phantom become unsolved?

After losing your family in a tragic fire, awakening extraordinary powers, and enduring four years of HYDRA experimentation, you've spent the past year reclaiming your life. Now, with your freedom restored and your abilities honed, you're ready for a new beginning as the Avengers' newest recruit. Living among Earth's mightiest heroes means adjusting to unfamiliar routines, navigating complicated personalities, building unexpected friendships, and learning to trust others again. Between dangerous missions, late-night conversations, team gatherings, and the possibility of an unexpected romance, you'll discover that becoming an Avenger is about more than saving the world.

A small-town bookworm arrives at Jujutsu Tech, only to become the unexpected obsession of two rival fraternity heirs—one golden, Satoru Gojo, one dangerous, Ryomen Sukuna —in a high-stakes college romance where the only thing more ruthless than the parties is the pursuit.

You just got into UA. This is MHA with a lot of characters having Instaroam accounts, I hate that so many don't have it, that's why it's a self insert you can choose your own story.

You were never meant to have a life of your own—only to be an experiment, a weapon, and a success story buried beneath the secrets of Project Genesis. Rescued by Young Justice with your memories shattered and powers awakening inside you, you must uncover who stole your past. But somewhere between dangerous missions, unexpected friendships, and a family you never thought you’d have, you begin to discover something Genesis could never manufacture: a reason to live beyond your purpose.

You work as Tony Stark's personal assistant long before the Avengers exist, when Stark Industries is still primarily known for technology, weapons, and Tony's increasingly eccentric public image. Your professional relationship starts with schedules, meetings, impossible demands, and Tony deliberately testing your patience, but spending more and more time around each other creates an undeniable tension neither of you openly acknowledges.

A Marvel enemies-to-lovers story where you and Bucky Barnes are forced into mandated therapy — and he's the only one who can see the rage you've spent years hiding.

You're Spider-Man's kid sister, and tonight you got drunk flirting with the Avengers before big brother Peter dragged you away covering his back.

After Brand New Day, you join Marvel's New Avengers — and the one person who can't keep her hands (or feelings) off you is Yelena Belova.
