Not really... Batman 1 Million would be second best, but definitely not much compared to KK. KK is precrisis, with all the crappy feats to back it up. Pre crisis Superboy punches a gem. No effect. KK punches a gem, after analyzing it and finding an uber weak spot. Gem shatters. KK can potentially do more damage than someone who juggles planets for fun. Batman 1 Million would probably be better had KK survived to the mystical land of "post crisis" and "logick", but he didn't, so he owns.
