White Queen (Smallville)

Amanda Waller hired Cameron Mahkent aka Icicle to hunt down and kill members of the Justice Society of America, using his anger towards them as a catalyst. She later sent clues to Lois Lane about the JSA and Icicle to which she began investigating. After giving Lois time to investigate, Waller visited her, telling her that she planted the classified information and gave her a phone before leaving, all this without introducing herself. When Icicle failed in his mission, Waller took him into custody and revealed that he had actually succeeded, having been used in order to shake up the JSA and bring them back together. She then aimed a gun at him and said "Welcome to the Suicide Squad" before shooting him. Waller then met up with Tess Mercer in the Checkmate base, at which point revealing that Tess is a Checkmate agent.
