superman for the win. superman beats polaris, the guy has same power like magneto, if you make a comparison you can see superman beating magneto too. and superman is too durable for magneto to rip metal out of his body. magneto has no way of countering superman's speed and strength, superman is going to break mag's force field and beat the crap out of him. on the other hand, most of magneto attack won't hurt superman, or it will get dodged by superman.
