Why did he feel the need to investigate it then?
Ever heard of the quote, "God works in mysterious ways"? Well, think of it this way, a supreme being works in mysterious ways. The same way, a ghost who is suppose to be the wrath of god gets destroyed by by beings soo much weaker. It's a comic and don't try to apply a lot of logic into it.
He obviously was not, since his power was described in finite terms.
and infinite as well. I'll let Mr. M answer this question
Really, because I haven't seen that. In addition, it makes no sense, considering it would allow any random no-limits fallacy to be prevalent. So if you have a character who is supposedly unbeatable but the strongest thing in his verse is just a guy with class 10 strength, that means that even Galactus or LT can't beat him? roll eyes (sarcastic)
No, you missed the point. It means something else. Imagine I bring a character from Marvel into DC. Lets say Silver Surfer. He would be powerless because nothing is powering him up(Galactus), and the power cosmic isn't the same as DC. That would mean he is powerless. So we apply the same thing with Mandrakk, that only CA+Superman story should beat him.
It's stupid which is why he shouldn't be put in a Vs Thread. There is no point in the fight. One side says my argument, and the other says that it doesn't apply Marvel. It's never ending.
The only feats Mandrakk has is, he was eating DC Universe, he was defeated by an armor that can ADAPT to any situation instantly; powered by the best story. He has eternal power. He holds the bleed, and the regular monitors, and other beings in DCU pale in comparison.
As for the business withe Primal Monitor, I told you there can be SOO much theories on who he is. So far, there are many theories on who created the universe.
If we go by what FC is saying, PM is a organism( very big), DCU is a germ inside the PM which is growing(with more stories). Superman created the Universe. Mandrakk is eating up the DCU (everything) and he is the concept of evil(evil part of story)
So if we go by that, PM is a Supreme Being in the story, but he didn't created the story(DCU). Though, these theories can contradict. People can say, the presense created the universe because he admitted it when he say the Spectre and he said that these are his toys. Then there is Superman, Krona, Source Wall, PM, an probably a few more. Then we have the thing about the supreme being. We got the Presense, and the PM.
All in all, just choose who you want to be PM, at the end it doesn't even matter. I don't think the authors were even thinking this deep.
