Logically I know that, as time progresses and we get further and further away from WWII, Holocaust survivor Magneto will have to be retconned just to make the timeline make sense.
…But in my heart Magneto will be a 150 year old ornery bastard who refuses to die on principal and probably got into a fist fight with God so he could go back to Earth and spite bigots everywhere by killing whatever shithead congressman decided mutant kids needed to be put in camps this week and then yelling at the Xmen on live TV.
