Viper draws first blood. The Widow— like Spider-man— is weary in both mind and body. At first, that bone-crushing fatigue costs her dearly. But as the fight progresses, she reaches deep inside herself… drawing on her indomidable will, a part of her so special that— even if she was the school teacher she’d once believed her self to be— it would have set her apart from other women. And by touching that unique corner of her soul… she finally, truly, knows who she is. Not Nancy Rushman, but Natasha Romanoff, the Black Widow. The best secret agent in the world. Against her, Viper doesn’t have a prayer.
Natasha: You’re beaten, Viper.
Here’s the conclusion of this fight, if you were wondering.
