Supergirl #62

Supergirl unfairly judged Buzz of a crime he didn't commit. Now, knowing the truth, the guilt-ridden heroine tracks Buzz all the way to Gotham City. Unfortunately, it looks like Buzz really is on the wrong side of the tracks this time. He's aligned himself with Harvey Dent, a.k.a. Two-Face, whose kidnapping of a scientist leads to the creation of another bizarre foe for the Maid of Might!
