Charles Frankenstein was a scientist and visionary originally responsible for giving life to a creature stitched together from the remains of corpses. This creation, who has since become known as Viktor, recognized himself as being different and so demanded Frankenstein to create a mate for him. Charles acquiesced and used the elaborate equipment from this tower laboratory to create a female companion for the monster. When the female creation first awakened however, she was stricken by the monster's appearance and shied away. Charles decided that this specimen was too perfect to simply give away to his original experiment and so denied Viktor his bride. Viktor was enraged and lashed out at Frankenstein, but Charles drove him away by threatening him with fire from a lit torch. The struggle culminated in an explosion, which tore down a large section of the laboratory. Charles then decided to assume personal guardianship over his female creation that he named Eva.

Charles publicly introduced Eva to the modern world when they attended a party hosted by a wealthy countess. Eva comported herself quite admirably, but embarrassed Charles when she demonstrated an adverse, savage reaction upon seeing a house cat.
