Eltab
Lord of the Hidden Layer
Gah. How unimaginative and banal.it's his superpower.
Were I in a comic book world, I suppose I would become an 'institutional villain' (not a super-villain). I'd keep inviting superheroes over to my medical clinic for 'just a few tests'. You know - CAT scan, MRI, thermal imaging, electron microscope, biopsy, poke them with needles, that sort of thing.
If somebody gets prickly about it, I could use my connections and 'rat him out' to the EPA (anybody who shoots energy blasts), FAA (anybody who flies), Civil Rights (any mind-reader) or some other regulatory agency that will hassle him for the next 20 issues - unless he agrees to take the tests I offered in the first place.
