While her husband was assigned to a security post at the heavily government-subsidized Brand Corporation in New Jersey, Patsy met the Beast and learned his secret identity. Walker had long idolized "super-heroes," and she elicited the promise from him that in exchange for keeping his secret, he would help her become a "super heroine". Walker's marriage eventually came to a bitter end, and she sought out the Beast, who was now a member of the Avengers, to remind him of his promise. Tagging along with the Avengers to investigate criminal activities at the Brand Corporation, she became imprisoned along with the heroes by the Corporation and her ex-husband. After they freed themselves, Walker discovered the Cat Suit worn by Greer Nelson in her identity as the "Cat". Putting the costume on, Walker dubbed herself "Hellcat" and used her natural athletic abilities to help the Avengers.
