basically the current justice league of america vs ol' pumbaa face.
straight fight with no knowledge of either opponent(s), and hal jordan is banned along with any loophole that involves him or his power/knowledge. also no outside help for either combatant(s), larz's troops are exempt for obvious reasons.
Seriously, very hard to beat this guy. His Orange Lanterns wont go away as long as there is greed in the universe. The entire time he fought the GLA Corps, he wasn't fighting serious. Fortunately, Hal was able to use his ring and deplete it completely only to stop on attack. JLA will lose here.
