Since Superman doesn't wear gloves...does he have fingerprints and has anyone ever tried to deduce his identity through his prints?
Since Clark Kent doesn't to my knowledge have a criminal record or hold a job with the federal government, his prints would not be in any system or in any file. So he may leave finger prints behind, but there would be nothing to compare them to, so they are essentially useless in finding out his identity.
isn't there soemthing about how superman has this aura around him?
maybe kryptonians dont leave an oil residue for fingerprints or he vibrates them so fast it the print is a smudge.
