The key to beating the Hulk is to knock him out before he gets too angry. But you're right, he'd probably whollop Doomsday because DD doesn't have a "fight over, you're dead" ability. He'd just piss off the Hulk.

Whereas Superman could do any number of things to remove the Hulk from the equation, especially if we're talking about pre-Crisis Supes. He could just throw the Hulk into space.

The Most Interesting Man in The World ;)

He can restructure parts of the universe itself. You can't destroy him because he can re-organize his molecules and come back. He has the limited ability to see in time. He can do almost anything.

Like I said, I think the only thing more powerful than Manhattan is someone wearing the Inifinity Gauntlet. They can literally do anything if they are wearing all six stones.

Well, assuming your in there universe.  I suppose there is no proof Manhattan's power works everywhere, but it's decididly canon that the IG only works in the dimension it's from.

As for heroes wearing it...  Adam Warlock wore it, but was instantly deemed not worthy and had it striped nearly right away... and all he ended up doing was remove both his good and evil sides from him self.

Except his "good" side was also evil.

Alternate versions of Silver Surfer and Reed Richards wore the IG too, not sure if they were good or evil.

Also, I consider Reed Richards a villian.

I mean, guy can create molecules that can't be destroyed, a weapon that could kill galactus and a PDA who uses an alternate dimension as it's fucking memory bank, but he can't find a way for Ben to turn his power on an off or just cure him? 

I mean i'm positive he could make this, and just doesn't want to, the bastard.

Whoever holds the infinity gauntlet wins, I guess.... since they can do... anything...

The naked blue guy from Watchmen

Sentry is actually more powerful than Dr. Manhattan.

Hah, Reed Richards has turned into a dick over the past decade or so. It seems popular to write him as more of a hard-ass now than it was in years past.

I knew Warlock had the IG but I hesitated to call him a "hero". Like you said, he's kind of third party and does what suits him. Kind of a tweener character that can go either direction.

I was avoiding other dimensions' characters. Obviously with the latest storyline in FF, there are a shit-ton of Reed Richards, some villains, some not, all super-smart with varying levels of technology. Both the DC and Marvel universes involve too many variants to ever keep track of who is alive, dead, powerful, weak, etc.

For the life of me, I can't remember if the Surfer ever had the IG in this dimension. I should probably go back and re-read that era of SS some time. I used to love the character. If he ever possessed it, I think he's pretty much the most powerful character ever (in his dimension, anyway). The Surfer is already in the upper echelon of Marvel heroes; with the IG, he'd be unstoppable. There are only a handful of Marvel characters who the Surfer couldn't whoop without the IG much less with it. Plus, he has that whole "nobility" thing and the IG probably wouldn't reject him as it has others. He's also smart enough to wield it, unlike others who basically had their brain overloaded by the thing.
