History
Tigra was assembled along with Wonder Man, Hawkeye, Mockingbird, and the Hulk to fight off Ultron-19.
However, Hulk had been afflicted by the "Great Cataclysm," which made him evil. During battle, the Hulk switched sides and turned against his teammates in an attempt to join Ultron-19. When Tigra lunged at the Hulk on her own and tried to claw his eyes out, he managed to grab her, and tore her in half.[1]
