Amanda Waller

"My identity is highly classified."

- Amanda to Ben Turner

Amanda Waller, known under the codename Mockingbird, is the leader of A.R.G.U.S. and the Suicide Squad.

Season 2
In "Keep Your Enemies Closer", she captures John Diggle telling him that she needs his help to rescue Lyla Michaels as she has gone dark in Moscow. She parts with a statement saying that A.R.G.U.S. are aware of what Oliver and him do at night.

In "Tremors", Amanda offers Ben Turner an employment opportunity for a "squad" (presumably the Suicide Squad) in order to shorten his prison sentence.

In "Suicide Squad" Waller visits Lyla and Diggle at their apartment and requests both of thier assistance's to handle a chemical weapon's situation, organised by Gholem Qadir an old friend/enemy of Diggle's stationed in Markovia. Waller then tasked with getting the Suicide Squad into position to take down the chem weapons and terminate Qadir. Phase one of the plan, getting Qadir's phone from him at an art exhibition, succeeded by Shrapnel attempted to flee and Waller activated the bomb in his head as punishment. Later when the squad found the chemical weapons Waller sent in a drone strike to terminate chem weapons but take Deadshot and dozens of civilians with him. However Diggle convinced Deadshot to flee with him but as Waller's drone was focused on Deadshot's tracking chip Lyla was forced to cut it out of his neck and throw it away. The re-directed attacked caused Waller to deal with the Markovian government on "unprovoked drone attack". Later Oliver Queen visited Amanda in her office and the two are revealed to have previously known each other and Slade Wilson who Amanda believed to be dead just like Oliver did. When Oliver asks for information on him, Amanda gives him insight on a new mercenary named "Deathstroke" who she believes could be Slade.

Personality
Amanda is described as the "formidable and enigmatic". However she seems to be largely devoid of emotion and equally ruthless shown in the almost casual way she kills Shrapnel when he tries to abandon the Suicide Squad and there is certainly a trace of amusement in her voice when she orders Deadshot to remain in postion as a beacon for the drone strike and when she sees Oliver in her office asking if he still wants to kill her. This shows that whilst she maintains more composure over herself and what she shows the people around her, she is little different to Bronze Tiger and Deadshot.
