The Sadistic Six was a group of five supervillians enemies of Force America. They were lacking one team member because in their past encounter with Force America, Acid Reing, their sixth member, was lost.

After Ghastly, the Dead Clown defeated and humilliated Force America, the Sadistic Six tried to make a comeback and recruit Ghastly in the proccess, but they found themselves face to face with what remainded of Force America. In a open fight, (and behind the panels) Force America was destroyed, with only Captain Hero surviving. Whatever happened with the Six, the five, I mean is unknown, but most probably they also fell in their last battle.
