After news hit that there would be a spin-off series, titled Waller, details about the show and the cast have slowly been revealed. Amanda Waller is the head of the A.R.G.U.S. (Advanced Research Group United Support) that heads up the members of the Suicide Squad and generally commits minor acts of terrorism in order to avoid even larger catastrophes. In the DCEU timeline, Waller first appeared in the 2016 Suicide Squad and has since been in a number of DCEU properties, always as the same stone-faced, no-nonsense boss who casually uses supervillains to achieve her ends.
