Hellcat

When Patsy helped Hank McCoy and learned of his alter-ego, she promised to keep his secret safe as long as he promised to help her become a "super heroine". Soon after the Beast left the Brand Company, Patsy divorced her husband and went looking for the Beast. She found him working as an Avenger and reminded him of his promise. Beast, wanting to keep her promise, allowed her accompany him on an Avengers mission which was relevant to her.

She and the Avengers went to investigate the illegal activities of a private army quartered in a Brand Corporation-owned building--the same company her ex-husband worked for. It was there that Patsy found one of Greer Nelson's (the hero known as Tigra) old costumes from when she was known as The Cat. Patsy donned the costume and took the name 'Hellcat'. Inside the building, she traveled with the Avengers to the Squadron Supreme's dimension. Upon their return, the Avengers were captured by Brand operatives. Hellcat managed to escape and threatened her ex-husband with her claws if he would not release the Avengers. Patsy raked Baxter's face to prove that she was serious, so he complied and released the Avengers. Baxter vowed vengeance after he was humiliated by his ex-wife. After this mission Patsy was offered a membership but she was persuaded by Moondragon to train in psychic ability and advanced barefoot martial arts on the moon Titan. The training gave her minor psionic potential. Once returning to Earth, she assists Doctor Strange in a battle and before long joined his superhero team known as the Defenders.

As a result of her experiences in hell and her resurrection, Patsy has a "demon sight" perception that allows her to sense mystical phenomena or those items or persons tinged with mystical energy. She is also surrounded by a mystical field that can deflect mystical attacks. It also allows Patsy to summon a costume that mimics her original Hellcat costume, and it appears in a fashion according to her whim.

Hellcat once possessed enhanced psionic abilities, due to the mental stimulation of Moondragon’s Titanian technology and training. She could move small objects telekinetically, resist mental control, and on one occasion was able to generate a psychokinetic force-blast. Moondragon has since used her own advanced psionic powers to undo the effects of her psychic augmenter. Since then, Walker’s psychic abilities have returned but to a far lesser degree than at their peak. She no longer has any psychokinetic ability, but she is still sensitive to certain psychic phenomena. Her yellow costume also gives her enhanced strength and agility. Her gloves on her costume have steel tipped claws.
