Black Widow has also been altered genetically although originally she was completely human, just like the other three.
No, she wasn't made up for the movie. She's been part of the Marvel universe for almost 50 years, in various guises. Scarlett Johanson is playing the 'original' Black Widow, Natasha.
Nick Fury of SHIELD is the catalyst that brings them all together, but Black Widow has been with SHIELD longer than any of the others.
I know far too much about comic book heroes......
