Tigress was a worker at the Chimera Institute.
Being a splicer herself, Tigress was part of Dr. Cuvier's group of followers who declared war on the "norms." Together with Ramrod and King Cobra, Tigress broke in D.A. Sam Young's house to kill him, given to his outspoken determination to outlaw splicing. Even though she had animal genetic augmentation, she was outmatched by Barbara Gordon.
Tigress was forced into hiding afterwards, and while staying at the Carmine's Taxidermy Studio, Batman broke in. She fought him, but was eventually injected with an antidote that reverted her back to human. She was then arrested.
Powers & Abilities
Tigress had been spliced with a tiger's genetic material, bestowing her with strength, stamina, agility and an acute sense of smell. She alone detected Batman twice: when he trespassed the Chimera Institute and Carmine's Taxidermy Studio.
