Lorna Dane (Polaris) Edit
Polaris has a great ability to be able to levitate objects metallic and nonmetallic, with her electromagnetic field she can levitate objects and destroy them in the air, or through a small manipulation of gravity, can also cause non-metallic objects to levitate in the air and manipulate it through electromagnetic energy.
Max Eisenhardt/Erik Lehnsherr (Magneto)Edit
Magneto can manipulate metal at the atomic level and make it take different forms. Magneto also demonstrated to indirectly manipulate non-metallic objects via metal ores they may contain, for exxample the huge island that Magneto levitated due to iron ore that was therein. Magneto is also capable of creating powerful electromagnetic fields capable of levitating nonmetallic objects, he can also do this via force fields.
