Natasha is an elite Soviet black ops agent. Very little information is available about her past. The woman herself is a seasoned professional (and, in the words of some, a cold-blooded killer). She deals only with the most severe affairs of the Union.
While the Union's agencies continuously dismiss and/or incarcerate journalists who question Natasha's military conduct (due to reports of shocking cruelty she shows on the battlefield) or the validity of official sources on her life and career, the rumours persist.
