The team knows Tony—he is a selfish, impulsive, playboy that doesn't work well with others. Which is why they don't understand why Pepper still works for Tony or why Fury lets him do whatever he wants. It's only when the team discovers that Tony is hiding something—someone, that it becomes clear they actually don't know Tony at all. (mentions of child abuse, tony's secret kid)

[Marauders Era] [Sirius Black x OC] [AU] Adelaide Fawley, a member of the sacred 28, was widely known as The Pureblood Princess. As the heiress to the Most Noble and Ancient House of Fawley, she grew up amongst the proud, noble, and prejudiced. She was raised to conform to the beliefs that contradicted every fiber of her being. She acted her part well. Too well.

Bucky Barnes: hitman, wanted man, man with a plan - find out who he is & get this damn arm fixed. How can he do that? Find an engineer; someone isolated from anyone else who won't ask questions. Cue Alvie Kennings, the dropout genius, a loose cannon that's worth the risk. But Bucky isn't the only one with skeletons in his closet; Alvie understands him more than he had ever planned.

When the Avengers seek out the help of an expert on the occult, they get more than they bargained for in the form of two brothers who have literally been to Hell and back. No one could have foreseen the consequences of this meeting, but as the old saying goes: When you gaze long into the abyss, the abyss also gazes into you. ***Noncompliant with Avengers: Age of Ultron***

"You cause me concern," Fury said plainly, sliding the folder closer. She read the information, an increasing look of alarm making its way onto her face.

Or am I just special?" Now: post-Avengers

With a notorious killer on the loose, her father's name on all tongues, Harry's search for answers to questions he shouldn't know to ask, Azkaban prison guards haunting the castle, and attempting to reign in her newfound, uncontrollable temper; Lillian didn't have time to be babysitting baby Slytherins and teaching charms...too bad that was exactly what she found herself doing.

Sequel to Seraphim. Nova Maddox works under Tony Stark as a biomechanical engineer. She's also a Legacy. James Barnes doesn't know what he is, but he's sure that Nova is the only one in the Tower who's capable of fixing his arm. A little oblivious and super mouthy, Nova doesn't see a threat in James. Too bad he doesn't agree with her. It's the makings of a beautiful friendship.

She was supposed to be just another experiment, another number. Then something went wrong. She escaped with a gift, a dangerous curse that only hurt the ones she loved. Years later, she back on the run, trying to escape the monsters in her head. She thought she was the only one who had to face these kinds of demons, then she met the man whose brain was stuck in a blender. Post AoU

It was only logical. She was a doctor; so she knew everything about keeping his body capable and alive. And with his new mission - self-given mission - of hunting down his handlers and their lackeys, there was bound to be injuries to his person. So he was bound to have use for her, right? Right. Now... To hide her from Steve... (Bucky/OFC Post!CATWS)
