Dasha Petrov

Dasha Petrov was a Soviet spy on board the SS Joly Wanderer who was tracking down an alien supercomputer for the Cold War effort. She killed the original carrier of the supercomputer Anton Skutnick with poison in a golden nail before tracking it down to Ian Chesterton, Barbara Wright and Doom. Doom threw a glass component in front of her, unleashing nanoforms which destroyed her and hijacked her body, turning it into a supercomputer. (AUDIO: The Steel Cascade)
