From Killer To Hero[DISCONTINUED UNTIL FURTHER NOTICE]

Lets change up the story a bit. What if Natasha Romanoff didn't go to New York to observe Tony Stark, to see if he was fit for the Avengers Initiative.
What if she was sent to KILL the Iron Man, Tony Stark, to keep the Avengers, which could challenge KGB and Hydra, from forming.
She becomes Natalie Rushman.
But in the struggle to kill Tony, she realizes what she was asked to do, why they wanted Stark dead, and she defies her mission to keep Tony safe from other KGB operatives that were sent to finish what she couldn't.
During this, she struggles to keep her status as an Russian assassin a secret, and of course, since KGB now wants her dead as well, she fights for her life, being attacked every time she left Stark Tower, which is where she lived, and eventually she had no choice but to tell Tony who she was and hope to god that he would help her.
Also, she catches Director of SHIELD, Nick Fury's eye, and he recruits her for SHIELD, taking her into his protection, where KGB can't reach her, and she later becomes an Avenger.

CREDITS GO TO MARVEL AND STAN LEE AND ALL OF THE CREATORS.
This is once again another one of my mind-numbing boredom cures, so let me know if its actually half way decent,(since I've re-edited the fist chapter of this and Believe like twenty times)
