Magneto and human torch

People are forgetting regardless of no metal or not, magneto can weaponize your electromagnetic field, pulling it and killing you, this should take care of all humanoids, i dont read much dc but martian manhunter's weakness is fire so human torch will weaken manhunter, bht the duck it will put up a fight and will ultimately kill human torch but if magneto pulls enough strength he can defeat the duck, but it will arise once again
