Marvel. Katya, originally Jinx, an assassin and spy for years alongside The Winter Soldier, was redeemed years ago when Steve broke her out of Hydra’s facility for help to find Bucky in exchange for freedom. Over time, they grew a friendship and sibling like bond, and she grew one with the rest of the Avengers slowly but surely. She is now going by her birth name, Katya, and part of the Avengers team…she doesn’t remember her past with Bucky though.
