Value 2 JP
The superhero generates a potent magnetic field. The superhero sets off metal detectors, fixed or portable, he cannot use a magnetic compass because it will always point to him, he takes a -2 penalty on Craft (electronics), or anything else that involves electronics being placed within 5 feet of him. Any magnetic recording medium (tapes, hard disks, credit cards with magnetic strips, etc.) must make a Fortitude save (DC 10) every time the superhero handles them, or the data is permanently and irretrievably scrambled.
