@vuviper: Fine...but the rules are morals off, to the death...so what he wanted to do is irrelevant to what he actually can do. As to the Martians healing ability...since when is the Hulk a slouch in that department? His healing ability is so extreme it's broken...and with his rage increasing all his powers, he's more than a match for a White Martian...which means the Flash will his hands full.
Exactly since Morals are off, there is no reason for Flash to hold back him IMPs like he normally does. And I brought up martian healing to explain why he was back in the fight later in the arc, I wasn't comparing it to the Hulks, but I'm pretty sure J'onn has regenerated from worse than Hulk. A white martian isn't a match for a Bloodlusted Flash, so even if Hulk was a match for a white martian (which he isn't) it wouldn't say anything about beating Flash.
