Batman and the Outsiders #20

Part two of "The Truth About Halo" arrives with a cover that puts the tension front and center: a blonde woman in a black-and-yellow costume reels in agony while the faces of Batman and his Outsiders teammates look on in shock above her. Facing her down is Syonide — identified by the cover's own bold caption as the villain who "killed Halo once… and she's back to do the job right!" — rendered in a striking pink-and-blue costume and wielding a serrated wire with cool menace. Mike W. Barr and Jim Aparo were clearly firing on all cylinders with this 1985 entry, delivering a cover that makes it genuinely hard not to flip straight to the story inside.
