For example, I believe someone said that Kryptonnite robs Superman of his powers. For the most part, that's not the case. Yes, it is actually A good example of this inconsistency is that he is rendered powerless when confronting Lex Luthor on the Kryptonite continent, and yet later on is still capable of heaving it into outer space despite the fact that the entire continent consists mostly of (if not entirely of) Kryptonite. Well I think inconsistency is the key word there. Like I said in an earlier post, he could have used a Force Point to shrug off effects of kryptonite while doing the lifting feat at the end of Returns. In the Mutants & Masterminds game it is explained that Superman spent his Hero Points (Force Points in that system) and used all the options in the game that enhances your abilities (in this case strength) and in doing so dropped himself to a dying state. I would also like to clarify that he does not nearly die from overexhaustion ... he nearly dies from overexposure to Kryptonite. This is speculation, not fact I'm afraid. But yes the kryptonite did factor in but it wasn't just kryptonite that nearly killed him. The fall back to earth after the lift is also a MAJOR factor. I don't know if you have seen Spider-Man 2 but a similar situation unfolds in that movie when Spider-Man stops the train. You can pass out and die from overexhaustion. Back to the subject of inconsistency, the same can be said about his powers. In some cases he has trouble lifting an airplane; in others he can move entire planets without much effort. In some cases he can outrun bullets; in others he can move faster than the speed of light. Thats the case with all comic book characters. But that still doesn't change the fact that you can divide his power levels into time periods (golden age, pre-crisis ect). Anyone who knows even the slightest bit about Superman (or any comic book character), knows this. Yes, his power isn't always consistent with the previous issue for example, but "power periods" do exist. The current Superman isn't nearly as powerful as Pre-crisis, and the Golden Age isn't nearly as powerful as the current. But there is really no need to debate this, as it is pretty much comic book lore. Regardless, however, it is a general fact that he is one of the most powerful beings in the known (DC) universe. This is completely true . In the marvel universe too IMO. Only very few, non-cosmic, beings can match his power.
