Biography
Whitney Frost was presumably a former lover of Tony Stark and was among the highest ranks in the Maggia family, former clients of Stark Industries. When Tony Stark started searching for stolen Stark Tech using the Iron Man Armor, he found himself trying to take down the Nefaria compund, which Whitney was in charge of. The search for her left him in the tunnels of the compound. She was crushed by a piece of the wall of the room she was hiding when the destruction of the weapons protecting her made it explode.
