Tigra

Greer Grant lived in Chicago, Illinois. She was a sophomore at the University of Chicago when she met her future husband, policeman Bill Nelson. She left college to marry him. Bill was killed in an off-duty shooting, and Greer had to find a job of her own. After weeks of searching, she ran into her old physics professor, Dr. Joanne Tumolo.

Dr. Tumolo was working on the human potential experiments that turned Shirlee Bryant into the super powered villainess called the Cat. Not trusting the test subject chosen by her financial backer, Malcolm Donalbain, Greer persuaded Dr. Tumolo to let her undergo the experimental treatments as well. She emerged with superhuman physical and mental capabilities. When Donalbain had Dr. Tumolo's lab destroyed with dynamite, Greer donned one of dozens of the Cat costumes that he had created and the doctor had appropriated and set out to put an end to his scheme. With her new abilities, she adapted quickly to the strange garb and wrecked Donalbain's headquarters. Rather than let himself be touched by the Cat's raking claws, Donalbain committed suicide. A fire set off by the ruined equipment destroyed Donalbain's headquarters.undefined

Greer embarked on a brief career as the Cat, mostly battling old Daredevil foes. One day Greer returned home to find HYDRA agents attempting to kidnap the Dr. Tumolo. She changed into her Cat outfit and drove them off, but not before one had shot her with an alpha radiation pistol. Dr. Tumolo told Greer she could save her from the radiation poisoning by changing her "into one of us." Though Greer had no idea what her friend was talking about, she agreed. "Life is precious to me, Dr. Tumolo -- in any form!"

Dr. Tumolo flew her friend by private jet to Baja California. At a secret gathering of the Cat People in a cave, Greer was given an injection to make her body like theirs. With their combined mental powers the Cat People bound the soul of one of their greatest warriors to hers, and Greer became the reincarnation of Tigra. She was given an amulet, like the ones all the Cat People wore, which enabled her to change back to human form. Tigra prefered her feline form and abandoned both previous identities.

Tigra has belonged to both the Avengers and the West Coast Avengers.
