In her first appearance, Spider-Woman was to be an actual spider evolved into a human as imagined by writer/co-creator Goodwin. Her debut was shortly followed by a four-issue story arc in "Marvel Two-in-One" in which Wolfman presented a different origin retcon as he felt her original origin was too implausible for mid-1970s readers. During this arc and the premiere issue of her own comic, Spider-Woman was identified as the human, Jessica Drew (combining the first name of Wolfman's daughter and the last name of fictional detective Nancy Drew), who had memories of being a spider implanted into her by the terrorist group HYDRA. Her costume was also redesigned for her series so that her long hair was uncovered, becoming a prominent part of the character's appearance.
