Alright, so I decided to do something very much against my core of self, and decided to not catch up on WWH, listening to what you guys had to say, and basing my entire thoughts on that alone, and LATER read all of WWH, to see how it may differ, and how that would change my entire statement on it, and how it would sound afterword. And to start, my reading it DID change (as we all knew it would) how I saw the end of WWH in regards to the characters, and displays, and junk like that.
And obviously, it's going to end in the final battle between the Sentry and the Hulk, and their prospective power bases, as most of the argument seems to be held there. "Who's stronger? Who beat who? Who cancelled who? Who did what to who?" And, in all truth, it will make me seem like a Sentry fan girl, as I do spend quite a bit of time defending him (though fairly, as Corp would defend Thor, without overexpressing), or at least more so than usual.
In the end, it did appear that Sentry DID get to access power he normally does not, though cutting totally loose isn't exactly what I WOULD say he did. He did bring out some power, but it became quite obvious in the book that he didn't bring it all out, nor WOULD he bring it all out, and would, in fact, give up the fight itself.
We do see Sentry injured by the Hulk, but not severely, where we ALSO see this in the Hulk, who does seemingly get hurt, but not badly. However, it's in their final combat as the Sentry and Hulk (as opposed to Reynolds and Banner), that gives me this notion. Throughout the fight, the Sentry shines, literally at high levels of power, and is getting INTO the fight, wanting to brawl, wanting to smash. We start to notice his face becoming darker, and given his personality shift, it's very likely to assume it's a Void emergence, which might have one of several effects. Since it shows that the Void and the Sentry's power tend to negate each other (thus, preventing huge overflow of destructive energy, and the Void always seems to be helpless against the Sentry, so it may simply be a Void<Sentry affliction, and the power may be lower of that), there might be a reduced Sentry power. It may be, the Void was emerging, and given his damper from the Sentry power, the Void was in reduction. It may simply mean that the Sentry isn't the be all end all in strength as we mainly thought of him as prior to WWH. But one thing is glaring in all of it, is what Hulk tells the Sentry/Void about making decisions about being a hero, and a destructive being. Of course, THIS is what always trips up Robert, and in course, the Sentry's power levels, is guilt of responsibility. Much like Zom Strange, this hits Robert deep within the Sentry/Void personalities. Given the fact that Sentry/Void was just short of bloodlust shows that the Void was on the point of emergence/domination/replacing the Sentry, also gives us the idea that Robert simply shut his powers off, especially when he thanks Banner, indicating he was thanking him for reminding him who he was/could be/is/whatever.
So, all in all. While the Sentry was written to be releasing more power than he seems to have ever before (apparently Galactus wasn't that hard to fight), it leaves it wide open that we still haven't seen the Sentry's full power, as it looks like he stopped himself before he got out of hand.
