But now, determined to fight for mutantkind's survival on his own terms, Magneto sets out to regain what he's lost-- and remind the world why it should tremble at the sound of his name. Magneto will safeguard the future of the mutant race by hunting down each and every threat that would see his kind extinguished - and bloody his hands that they may never be a threat again. But as horrors from his past loom large and S.H.I.E.L.D. agents pursue him, will Magneto soon become the villain he once was?
