probably superman, because is very fast and strong, but lets think a little, supes come flying fast to hit mags, but mags protects himself with a electromagnetic field, off course supes will destroy it, but it would provide time enough to magneto control the iron in supes blood, destroying his brain, and all the rest of the organs. supes is the man of steel, but only in the outside not in the inside.
iīm thinking in a strange vs flash combat, strange could murder flash in so many ways, but if you put both of them in a corner and scream: ready set go, flash would be so fast that he would KO strange.
people, the whole iron in your blood talk was a joke, its not the iron in foods, its the actual type of metal that mystique pumped in the security guys ass lol
but yeah i still think superman would own magneto in so many ways, if anyone knows superman you know he's gonna use the eye-beams around the start of the battle
if mags manages to make adimantium body armor in like half a second, and adimantium weapons, along with an army of all other seriously hard scrap metals and sentinels, I think Mags could have a change.
man.. reason mystique pumped iron into that guy was so magneto could break FREE out of that plastic(or whatever it was made of) cell, simple as that, he could have killed that guy anytime he wanted, but killing him would still leave him in the cell!, duh!.
we're talking about comic book magneto, not the movie, anyway i've never seen the movie magneto use electromagnetism as far as manipulating metal, so i think he couldnt have killed that guard anytime he wanted
and you are correct, the movie magneto is only able to control metal. if it was the comic magneto he could destroy that prison with a tough.
about tyhe comics, the numbers are different because i have the portuguese versions, so maybe another one could help you on that.
but in the comic that shows maggot tolding his story to wolverine, you can see magneto killing a bunch of men controling the iron in theyīre blood, very cool.
he once stop the x-men from moving (by the blood thing again) just to speak a few words to them, i think this happen before mags took out the metal in wolverine, but that comic is not mine, so iīm not sure, and like iīve said i donīt know the number.
Guys you are forgetting something, Superman Biomagnetic Aura, the second source of his powers, Magneto just sense the presence of this aura around Supes body, stretch it, and throw Supes a piece of metal of high density and 600mph, stucking it into his heart, good bye Superman.
