Initially paid by Yavlinsky to terminate the latter's rivals, she was a triple agent working for The Consortium; she acted first as a "hired assassin" in the terrorist group Black Baton in Syphon Filter then as a resource of The Agency during the events of Syphon Filter 2, all while at the behest of The Consortium. Specifically, she was apparently in cahoots with Vince Hadden but it then transpired that Mihai Niculescu in fact hired her, during Syphon Filter 3 and Syphon Filter: The Omega Strain. Gabriel Logan first met Mara during the Washington D.C. attack and he (along with Lian Xing and Teresa Lipan) have worked to capture her since that point until her eventual assassination by Gary Stoneman (at Logan's request) during Syphon Filter: Dark Mirror.
