Origin
Orphaned by a Eastern European revolution she lived a transient existence across Europe during her adolescence and early adulthood surviving by criminal activities of various sorts.  Joining the ranks of the terrorist group HYDRA, she was one of the few female agents of that time.  Promoted to the New York terrorist cell, she donned her green costume, dyed her hair, and assumed the title of Madame Hydra.

When her relationship with HYDRA turned sour, Madame Hydra inspired to other goals.  Killing the villain who was currently using the identity of the Viper, she assumed his name and leadership of the Serpent Squad adopting more venomous techniques as the new Viper.
