Joan Sanders' husband, doctor Sanders, was murdered by the terrorist Kurt Ostrec. She sought revenge, especially as the Blackhawks had arrested him thrice, and he escaped every time. She wanted a more permanent solution.

To that end, she recruited the widows of several of Ostrec's victims, and formed the Tigresses, an organization modeled on the Blackhawks. Because they could not get to Ostrec while the Blackhawks were still active, she devised a plan that would get rid of them both. She would first coax the Blackhawks to come to Tigress Island, and trapped them. She would then signal Ostrec with this prize. But Ostrec smelled a trap, and attacked her; the Blackhawks escaped and finished the fight. In the end, Tigress failed in her goal; Ostrec was captured, alive. Blackhawk berated her for her foolish actions.

Even though versions of the character may have since appeared, this information does not apply to those versions.
