Ok but Magneto is still just a mutant... which is pretty much a human with a few added in / defective genes. He will get tired before Superman... get fatigued if he is forced to fight for hours much less if the fight took a day or two. he might be able to travel close to the speed of light (which I doubt but I will give you) but he cannot think that fast. Superman can.
What exactly is a will of iron?
He is a genius as far as things like cloning and mutations go. Not a battle genius or a very skilled fighter. Superman is though. Lets see... leader of the JLA or leader of mutants who always gets beat by the X-Men?
When Magneto is tired or hurt (after fighting Superman he will be both) he does not control his powers as easily. So he cannot do as much with them. Also he can do all of that extra stuff you said like control the different spectrums of light but it is a lot harder for him to do and takes a lot more of his concentration.
I have found one instance of him using his powers to lift a 30000 ton object... but not more. So your theory of "incidently, superman can only lift 30000 tons, magneto can go on way more than that"
-Show me the proof of him lifting way more than that
That wouldnt matter anyways... Superman has taken direct hits with nuclear weapons also... and lived. So that part of your arguement means nothing.
Magneto's telepathic powers as stated in Official Marvel Guidebook shows that he only as enough to help protect himself against other telepaths. He would not be strong enough to control Superman.
Even if I do give you all of the powers you listed above... (even though you portrayed them poorly and made them seem like he was a master of them all), it would end up that Superman has more endurance and would be able to fight for longer periods of time. Once Magneto gets tired he will start to lose control of his powers. Just like GLs powers weaken when they lose their concentration.
So again Superman would destroy Magneto. Sorry leonhartmm... A mutnant will never be enough to stop a near cosmic being. He is still just a gene defective human.
Instead of saying things like "I can't remember exactly" why dont you just say that you copy and pasted your entire arguement from the Marvel Handbook. Thats a shame... couldnt even copy right... trying to make it look like he is a master of all of those powers... End it.
