Find Your Own Fire
Mehehehehehehe. I just finished my finals. Boy, KMC has gotten a little bit more rambunctious last time I posted here. My two cents. I think most people would agree that if Galactus could absorb the Oan energies, he'd run over the GL's and the Guardians most of the time. The Power of the Guardians, while extraordinarily potent and virtually capable of anything, has been shown to be quite absorbable. The Manhunter's tech is a rudimentary example. They just suck it up and even a GL's will cannot prevent it. Never liked that, to be honest, but it happens.
The question remains, could Galactus absorb it? Someone noted that he had threatened to absorb Mephisto's realm and Asgard and the Black Celestial. But the first two are more magical and the latter involved some technology. I'm going to argue that Galactus could use his affinity for power absorption capabilities to win 1/10 here. I don't see how Manhunter technology would be so far beyond Galactus' ability to not constitute at least one win. After all, Silver Surfer absorbed it in a crossover.
But I don't agree that doing so would result in an automatic win for Galactus 10/10. Even if he could absorb their energies, the GL's and the Guardians could still theoretically fight back, aka, run away and fling asteroids at him. They'd come up with something. And the GL's have shown the power to contain a galaxy destroying blast, so the entire Corps led by the veterans and backed by the Guardians... I think they'd take a sizable majority against Galactus. Galactus would have to resort to mass matter manipulation (ala turning Hercules into an amoeba) or stasis/mind control (ala Infinity War) to eke out his wins. Or, dare I say it... click the Ultimate Nullifier. Mehehehehehe.
Physically, multiple star system destroying blast just does not cut it against the entirety of the GL Corps. If this were Galactus and his heralds versus the Guardians and their Corps, it'd balance out better. But Galactus on his lonesome, having fed on only one planet? Hey now... Sure he could incinerate thousands of them in a blast that utterly and immediately incinerated the Annihilation fleet (a fleet with teleportation capabilties mind you), but all 7200 and the Guardians?
GL Corps 8/10
BTW, I don't think the galaxy destroying blast containment feat in 'Sinestro Corps War' passes the smell test. They had 50 GL's create that wall which Superboy Prime rammed through in 'Infinite Crisis.' Granted, the only veteran present was Guy Gardner and everyone else were rookies and here, you had veterans like Salaak, Kilowog, Arisia, Green Man, Stel, Brik, Bzzd (my new favorite GL) leading the charge, but still... someone mentioned that it took dozens of GL's to destroy a sun at one point? Something doesn't pass the smell test. My theory is that the destructive capacity of the blast was an effect of its antimatter composition. It would expand out in a wave of antimatter and eventually nullify all matter within the galaxy. The GL's contained the antimatter in a concentrated focal point and a rupture into the "under-universe" appeared and the antimatter flowed into that rupture. That is where all the destructive energy went rather then being absorbed into the GL's shields. The GL's shields didn't fully contain the blast so much as to provide just enough resistance for the rupture to fully appear and suck all the antimatter into the "under-universe." And although Greenman's dialogue after the fact could support this, this explanation is overly technical and I would guess unnecessary until something comes along to directly contradict it after the fact, rather then before the fact.
