She is considered by her Russian masters to be one of the best Crimson Dynamo pilots ever, and was a graduate of their "Federal Dynamo" program. Nemirovsky frequently wears the Mark XIII armor, which is equipped with Dire Wraith technology. On at least one occasion, she used another armor (when she and Red Guardian battled Iron Man). After the Dire Wraith invasion, Nemirovsky was fired and renamed herself the Ultra-Dynamo.
After leaving the Winter Guard, Nemirovsky was a brief ally of The Mandarin.
