In my Suicide Squad series, I would put Conduit (Kenny Braverman) in Waller’s position because he’s ex-military and have Ra’s Al Ghul secretly financing the Squad. As for who I would put on it, these are my choices: the Reverse Flash (Eobard Thawne), Ocean Master, Talia Al Ghul, Klarion the Witch Boy, Scarecrow, Cyborg Superman, Star Sapphire (Fatality), and Maxima.
Blackfire and Lady Shiva are fantastic characters, @Samsonkillingtime, and would be great on a team of femme fatales. But, if you’re going to make a whole team of femme fatales, then you have to include the ultimate femme fatale - Catwoman. Also, Cheshire and Magenta (Francis Kane) would make great additions to an all femme fatales team too, don’t you think ?
