Eradicator
Too bad this issue didn't live up to the intriguing cover art. But the Eradicator, a small rock like object possessed with catastrophic energy, isn't a very cool plot device. In the end, it's really just Superman versus a rock, in a neat setting. And Jimmy Olsen turning into basically the Elongated Man, I could have done without. But it was a pleasant enough read. 7/10
