Though you were safe in hiding for over two years from both SHIELD and HYDRA, you are eventually discovered by Nick Fury who sees you as nothing more than a threat that needs to be contained. However, an old friend of yours, Clint Barton, talks him down and instead enlists you to work with Steve Rogers and his team on their own mission to destroy any remnants of HYDRA.
As if your situation wasn't complicated enough, it eventually becomes more complicated when you find yourself harboring a certain metal-armed fugitive who Steve is desperately searching for. Over time, more and more of your past comes back to haunt you; threatening everything you've been building with Steve and the others.

Summary
You're a skilled assassin, created and trained do whatever you're told. With all the same powers as National City's Girl of Steel, if ordered to kill, you'll do it, and you'll do it quietly...that is until a mission goes wrong that puts you on the DEO's map. Supergirl has been hunting you, and suddenly, you attract the attention of too many people. That includes someone from a past long since erased.
You receive an order to kill Lena Luthor, and for the first time in your life, you hesitate. You never hesitate. Never. But something about Lena's vibrant green eyes, and the way she calls for you, using a name that you don't recognize but still somehow feels right, puts you in a position where you can't harm her. Something about her makes you feel, and something about the way Supergirl looks at you, makes you feel so protected. Isn't she your enemy? When has the enemy ever made you feel so safe?
...and so confused.
Who's your ally? Who's the enemy? And at which point did those lines blur? Are you what you're told? Or is there something more that's being kept from you?

Summary
Dirk and Harper were well-known around Dutiful Exoneration, as they had ended their partnership with the organization a little under a year ago. Though Celia had been sending assassins after them ever since, they had always managed to evade her grasp, somehow catching on to who was after them every time. You wouldn’t let it happen again, you would complete your mission, and once again prove to everyone why you were Celia’s right hand.
You heard the hum of a car outside with no doubt that it was Celia’s chauffeur, a gruff and quiet man named Carl, with whom you were well acquainted. You slipped a ring on your finger, one that would surely come in handy later, a bottle labeled with an ‘x’ on it into your pocket, and lastly, slipped a gun beneath your clothing, careful to conceal it from view. A last resort, but one that you knew was needed, especially with Eddie and Volt in the vicinity.
--
Or, you're an assassin sent to take out several targets and have an encounter with the notorious hitman husbands, Eddie and Volt.

Summary
He licked his lips once, slow, absentmindedly. Then smiled. Not that it reached his eyes.
From his perch, he could see the smear of red on your knuckles. Could almost taste the moment you’d snapped. Whatever had triggered this, the sloppiness, the brute force, he wanted to know. Wanted to peel it apart until your pain was cataloged just like your movements. He imagined your hands trembling, breathing too hard, wishing no one would see you—And he had.
He always would.
Or..
One mission, that's all you had together, right? So why is he back..
