Mini Marvels - Tigra

Greer Nelson became a costumed superhero after her cop husband Bill was killed in a shooting. Undergoing an experimental procedure that gave her enhanced physical attributes, she called herself the Cat. Some time later Dr. Tumulo, Greer's old friend who had performed the procedure, was attacked by Hydra agents and Greer was gravely injured fighting them off. It was then that Tumulo revealed her true identity as a member of the other-dimensional Cat People. Having proven herself worthy by defending Tumulo, the Cat People decided to save Greer's life by transforming her into their champion, Tigra. With a new feline appearance and greater strength, speed and agility than before, Tigra became a regular member of the Avengers.
