Superhero Death Battles, Flying Cars, and Pop Culture in General! Oh My!

Since they both can warp reality to their desires it would be a tie there but Cthulhu would have the advantage in that it has allies in the other dark gods so Manhattan would be outnumbered.

 

I personally would agree with cthulhu winning. I think within their own universes both are basically unkillable in a physical sense. But Doc Manhattan is emotionally and psychologically still human for all his power and knowledge, and i think Cthulhu would drive him insane or warp his will to make him serve him.

 

That was my original thought, that he was still basically human, but if you remember from the book by the end he had pretty much lost all his connection with mankind.
He still wanted to care but he even forgot that she couldn't breath on Mars.
By human standards Dr. Manhattan is already so far away he might as well be a different species.

 

or hit him with a boat

 

Though if you think about it there's a good chance that the world wouldn't come out in very good shape as a result of such a battle.
Unless you could convince them to do it off planet I suspect the long term damage would be immense.

 

I actually read that the other way. That he can see everything yet forgets that Laurie couldnt breathe on Mars was to me a sign of how distracted he was, and how emotionally affected he was that the world rejected him and she (in her own way) rejected him also. The way he shuts himself away on Mars I thought was a very human reaction. Kind of a teenager with the powers of a demigod locking himself away in his room.

The fact that he has knowledge of so much of the past, present and future certainly gives him a different perspective than a normal person, and he maybe that is part of what makes him so detached at the end... but I still think it is probably that his mere exposure to Cthulhu (a being who's very existence is in contradiction to the universal laws Doc Manhattan thinks he is the keeper of) would send him insane without Cthulhu even particularly noticing him.

 

Ok, this is a weird battle...
Superman's super intestinal bacteria -vs- the earth's waste disposal treatment plants.
Who wins?
I think there may be a growing super bacterium in collected pockets of the world, centralized around Metropolis. One of these days it will attack...
