Hmm, along the same lines as night vision, might Faunus be sensitive to different frequencies? I could see Cardin (still don't have faith in him being a good guy) or someone playing a cruel prank on the Faunus students by blaring a high-frequency noise that humans can't hear at all. But it would be just in the obnoxious "nails on chalkboard" zone for most of the Faunus students, completely debilitating them.

The worst part would be that many of them couldn't cover their ears with their hands, having four. Of course, Blake would have a bit of explaining to do if she fell on the floor in agony.
