Hulk is merely holding together the device from which said field is being generated. He's not directly holding off Exitar's foot from landing on Earth.
He is indirectly though. The machine wasn't capable of generating a planetary forcefield in the first place without Hulks help, then he is still able to hold them together even with Exitar standing on top of it.
As Doom said, the fate of the world were quite literally resting on his shoulders.
Actually, the machine was capable of generating the force field by itself. However, the machine wasn't designed to withstand the resulting internal stresses for long. Thus, Hulk was needed to hold the machine together while it was doing its job.
Which is what I said. Holding the Celestial at bay or even simply erecting a forcefield around the whole planet wouldn't have been possible without Hulk holding the two anchors in place. Very nice strength feat for him.
That`s amazing. A weakened Hulk shrugging off adamantium bullets, displaying a crazy energy feat (negating NZ particles), and even getting a mention that he doesn't need to breathe.
It seems only Corvus' atom-slicing weapon has been able to pierce Hulks skin this side of Marvel NOW and even then it took considerable effort to do so. I'm not including the Savage Wolverine appearance as that seemed to be pure spite in all honesty.
Hulks hard durability has definitely been increased and fits in line with how he was originally depicted, as an invulnerable power house, and not overly dependant on his healing factor. His feats are becoming more and more haxx which will please some fans, I just hope Waid doesn't believe that simply throwing in a few extra feats in his run will be enough to turn the declining sales around. Hulk needs to be more than just a weapon.
Branlor, you have to discredit everything of Hulk' don't you? Oh anyway, nice job on the Revamped Galactus Respect Thread. That was awesome. That's why I hate Galactus being used as a doormat like in Chaos War just to show how powerful the new guy is.
