at her lab, which claimed her life. Greer then donned the suit, and set out to put an end to his scheme. With her powers, she adapted quickly to the strange garb and attacked Donalbain's headquarters, before convincing him to commit suicide rather than let himself be touched. A fire set off by the earlier fight then destroyed Donalbain's headquarters, including his copy of the enhancement machine. Greer then embarked on a brief crimefighting career as the Cat. Years later, another of Donalbain's Cat costumes surfaced when Patsy Walker discovered it while accompanying the Avengers. Donning it, she began calling herself the Hellcat.
