Or rather it's full title: TALES OF THE SINESTRO CORPS PRESENTS: CYBORG SUPERMAN. The issue actually gave an accurate depiction of the Cyborg's backstory, something Countdown is royally screwing up with (amongst other things). The Cyborg visits his wife's grave before assaulting the JLA's watchtower. It was spoiled in another thread that his goal is to die, if he kills Superman in the process it's a bonus. The Cyborg continues to explain that he doesn't even care to see his wife again. And then...well it's cold and gruesome. But his actions definitely tell the reader that, in this war, Henshaw is a villain that should not be messed with. Other than the Cyborg's motivations, this issue doesn't do much to further progress the Sinestro Corps War. The last scenes (on Earth) are cool, but I bet it'll be seen again in Green Lantern #24.
