Kazimiera is a Sokovian-born woman who's a bit like Nat - got a dark past that she's run from and is keen to forget. Only Kass isn't an assassin, she's a mercenary, a thief, and a damn good one too. Hacking into Stark Industries will bring her face-to-face with a certain genius, billionaire, playboy, philanthrophist, who is more charming than she would like him to believe... (TonyxOC) Will cover from the first Avengers all the way to Endgame. Suit up for some flirting, action, and lots of AC/DC and Led Zeppelin!
