After Dragon and the Chicago branch of S.O.S. prevent BrainiApe and a group of neo-Nazis from seizing Chicago City Hall, Barbaric and several Police officers take Dragon to a strip club for his bachelor party, where the festivities are interrupted by someone who appears to be Rapture, who claims to have been transformed into pure energy when she was "killed" by Darklord, and inhabited the body of her friend (and recent S.O.S. recruit) Lightning. Explaining that the battle with BrainiApe caused her to assume control of Lightnig's body, she eventually ends up fighting Dragon, who suspects that she isn't in fact the real Rapture. She escapes into the Underground - where it is revealed that she was in fact the villainous Impostor all along. Meanwhile, Overlord recruits Mace as his partner.
