Just like Deadshot and Captain Boomerang, Amanda Waller has been a part of the modern Suicide Squad mythos (not to be confused with the Silver Age Suicide Squad, which was a team of adventurers that only appeared in six issues of The Brave and the Bold) since the beginning.
The ends always justify the means in her book, even if it results in casualties.
She may not have superpowers or a colorful costume, but make no mistake, Amanda is one of the most formidable and dangerous individuals in the DC universe.
She’ll use intimidation, manipulation, blackmail and whatever other tools are at her disposal to ensure that her goals are carried out, which are usually on behalf of national security.
