The penultimate chapter of "K" presents Superman vs. AAB (The All-American Boy) in a no-holds-barred fight through Smallville! Only Heroes scribe Michael Green and his writing partner, Mike Johnson, could create the AAB — a supersoldier with Doomsday's DNA that's infused with Kryptonite! Can Batman help the Man of Steel defeat AAB, or will we witness "The Death of Superman" all over again?
