@thanofleeze: I've been hoping to be enlightened a bit in that regard myself. I remember he was said to be "powerful enough to crack a planet in half with a thought"(or something of that nature, during Rebirth), and taking on a very large group of Green-Lanterns while missing a hand(and overpowering them while holding back, if I recall). But I'm not clear on the circumstances.
Then it's a long fight until the team folks start tiring. They all fly and can stay out of the way, but none of their attacks can put him down. Barring something concocted for Rogue, they tire out and then get beat the hell down.
